FEB 14, 2020
Abstract The Western desert of Egypt is characterized by very complex subsurface. This usually forms a barrier to the oil and gas exploration especially that we cannot easily extract information from the seismic data. In the first few meters below the surface, the presence of hard layers like limestone and Dolomite. These are areas where limestone is dissolved and is usually filled with other rock types, the sudden change of the lithology causes scattering of the seismic data and loss of energy. The Abu Roash layers below the near surface are usually characterized by high acoustic impedance and sharp velocity variations, they trap the seismic energy inside them and do not allow most of the energy to penetrate downwards. In this paper we will show a successful study from the Western Desert where the use of new seismic data processing technologies and the integration of good seismic acquisition with the geologic and geophysical knowledge helped to clearly image the layers in the deep part of the area and led to a successful oil discovery.We utilized the non-uniform coherent noisesuppression technique to be able to model the linear and coherent noise of the data accurately and remove them.The data regularization played an important roleto overcome the acquisition irregularities and produced gathers that are much better for velocity analysis and depth imaging.The drilled well confirmed the interpretation from the seismic data and has hit its target accurately which giving Egypt a new oil discoveries in the Western Desert.

Title: petroleum and energy economics Abstract Cost Benefit Analysis (CBA) in environmental policy expresses its future benefits and costs in terms of money and in order to compare them on the present, CBA discounts them for a discount factor -which is the denominator of the formula. This entails that the future will have a decreasing value relative to the present. For example, a 150M$ cost, 80 years from now, at a social discount rate of 5%, worth today its 2%. This raises a big question about fairness and commitment to the wellbeing of forthcoming generations. Short-valuing the future entails not only an ethical problem, but also a contradiction with the definition of sustainable development which states that present development should not compromise the future of the next generations (United Nations 1987). On the other hand, giving the same weight to all future generations or zero discounting- is also not a good solution (Pearce, Groom y Koundouri 2003). This means that we should care not only for generations 80 years from now, but also for generations 1 million years from now or more, bearing all the cost to the present ones resulting in a heavy impoverishment. For this reason, it is a source of concern to find better discount rates of CBA of environmental policies that reflect better the cost and benefits to future generations without compromising the present nor the future development. However, the most recent response to the problem, is the declining discount rates which states that the social discount rate decline significantly over time (Weitzman 2001), in other words, the discount rate should be negatively correlated to the time. Actually, the United Kingdoms Treasury does its public policy appraisals based on this rule (HM Treasury 2013). Despite some researchers have proposed alternatives, there is still much to do.

Title: Quantification of Condensates Generated in the Gas Compression System by Phase Behavior Simulation for Field Production Validation Abstract In the gas compression system of the BarĂşa-V plant, water and hydrocarbon liquids are generated due to pressure and temperature changes. These condensates are reported as additional production and are deducted from oil production measured at the delivery point. It is necessary to validate field production by quantifying hydrocarbon liquids generated in the gas compression system. Steady-state process simulation and phase behavior study were performed to reproduce the multistage gas compression system, obtaining the flow (in bbl/day) of water and condensates generated in the compression and cooling processes of natural gas. From there, the factors that will enable the calculation of water and hydrocarbon liquids generated as a function of the compressed gas flow were determined. Favorable thermodynamic conditions for the presence of gaseous hydrocarbons, condensed liquid hydrocarbons and free water are found downstream the 2nd stage cooler (E-2), converting flow into a multiphase stream that is physically separated in the scrubber, by the effect of the density difference. The calculation of the liquid factor corresponds to 82% of the current value. Hydrocarbon shrinkage factor corresponds to 56.08% of the reference factor currently used. In conclusion, according to the simulation results for the shrinkage factor, the correction of liquid factor and the deduction of the liquid hydrocarbons from imported gas, the quantified condensates are reduced by 41.38% compared to current calculation. This results in a decrease of 350 bbl/month and 4.200 bbl/year in 2018. When there is no measurement system available, generation of representative models using digital tools for quantification of any phase flow has a direct impact on field production.

Title: Transforming sour condensate into value – A Kuwait Oil Company’s endeavor devised for maximizing potential of Gas Abstract KOC being a pioneer of oil & gas industry in the region, shoulders the onus for high quality production and transportation of gas to cover entire needs for energy in State of Kuwait. An accelerated development program resulted in production of targeted amounts of gas and Condensate from newer fields, however, it introduced significant operational and product quality concerns. This often resulted in production cut-backs or flaring of hydrocarbon. Moreover, KOC was dependent on downstream refinery for processing its entire volume of Sour gas and condensate in their Acid Gas Recovery Units (AGRU). In order to be less constrained and to reduce flaring, pre-engineered, modular based integrated Sour Gas Sweetening Facilities were conceived. However, excess sour condensate still continued to remain a challenge. Therefore, new treatment units were considered to sweeten the sour Condensate to meet required specifications whilst meeting regulatory, personal safety and environmental standards. This paper discusses the series of events that led to the development of a novel Condensate Treatment unit, with the focus on comprehensive screening of process technologies, energy conservation and process integration with existing units, the supposed economic benefits and environmental performance improvements. The selected concept had relatively low process complexity which led to higher availability and lower maintenance costs in the long term. Transforming sour condensate into value beyond established business functions have been a success of this endeavor. The concept also resulted in surplus value generation with expected earnings of around 216,000 USD per day. https://www.scientificfederation.com/oil-gas-petroleum-2020/program.php

Title: On similarity of volumetric heat capacity and capillary pressure fractal dimensions for characterizing Shajara Reservoirs of the Permo-Carboniferous Shajara Formation, Saudi Arabia Abstract The quality and assessment of a reservoir can be documented in details by the application of volumetric heat capacity. This research aims to calculate fractal dimension from the relationship among volumetric heat capacity, maximum volumetric heat capacity and wetting phase saturation and to approve it by the fractal dimension derived from the relationship among capillary pressure and wetting phase saturation. Two equations for calculating the fractal dimensions have been employed. The first one describes the functional relationship between wetting phase saturation, volumetric heat capacity, maximum volumetric heat capacity and fractal dimension. The second equation implies to the wetting phase saturation as a function of capillary pressure and the fractal dimension. Two procedures for obtaining the fractal dimension have been utilized. The first procedure was done by plotting the logarithm of the ratio between volumetric heat capacity and maximum volumetric heat capacity versus logarithm wetting phase saturation. The slope of the first procedure = 3- Df (fractal dimension). The second procedure for obtaining the fractal dimension was determined by plotting the logarithm of capillary pressure versus the logarithm of wetting phase saturation. The slope of the second procedure = Df -3. On the basis of the obtained results of the fabricated stratigraphic column and the attained values of the fractal dimension, the sandstones of the Shajara reservoirs of the Shajara Formation were divided here into three units.

In this work, the main study was the thermal behavior of biomass materials (artichoke, acacia, wheat, cotton and several urban wastes) during co-combustion with two types of lignite. Co-combustion of biomass and coal contributes to energy production and helps decrease the consumption of fossil fuels. Also, co-combustion represents a short-term, low-risk and low-cost sustainable choice of renewable energy sources, to reduce CO2, SOx and NOx emissions. Torrefaction processes of lignites, these five kinds of biomass materials, and also their mixtures with lignite, were investigated using the thermogravimetric analysis (TGA/DTG). This type of pre-treatment can improve the properties of biomass for thermal conversion by improving grindability, heating value, reducing the hydrophilic nature, and increase its resistance to biodegradation. Individual samples and blends were subjected to chemical and mineral characterization. Fusibility analysis was also subjected to determine behavioral fusion. During the co-combustion of these two lignites with biomass materials, it was observed that increasing the percentage of biomass participation in the mixture increased the combustion rate of the mixture, and the peak rate in the DTG curves shifted to lower temperatures. The results of the chemical analyzes showed that most biomasses presented high concentrations of Ca and K. Lignites, compared to biomass materials, had higher concentrations of Fe, Mg and Al. Furthermore, biomass materials showed a high concentration of Cu and Sr, while lignites showed relatively high levels of Ni, Cr, Sr and Cu. With the addition of biomass to the two lignites, the silicon content in the mixtures increased, while the percentage of aluminum was reduced.

Title: Reliability of Intelligent Completion Systems in Sandstone Reservoirs Abstract Through Intelligent Completion Systems, oil and gas production and recovery factor from new and existing oil and gas fields can be optimized. Intelligent well completions collect downhole data that allow the operator to selectively control completion intervals. Performance can be monitored realtime and operations can be adjusted remotely using downhole equipment. The primary objectives of these abilities are normally to maximize or optimize production/recovery, minimize operating costs, and improve safety. As established, a better economic output was recorded with an intelligent completed well compared to a conventional completed well. Based on the analysis of the results, risk management and sensitivity analysis, it was noted that the IWC technology presented an increase in oil production by approximately 50%, a higher return on investment, low attached risks, a high reliability, and a minimal water production amongst other added values, thus proving the multiple benefits of IWC adaptation. Over the years, intelligent completions have proven to be an industry winner with improved well operations and performances. Therefore a wider need for adoption should be encouraged in conventional oil and gas fields both onshore and offshore as intelligent completion systems are highly adaptable.

Abstract Natural gas as one the most significant fossil fuels, is playing a crucial role in national energy mix in different countries. Nevertheless, its applications have not been limited to energy providing, and has been used widely as the feed stock in production of different varieties of petrochemicals. So that most of new petrochemical complexes around the country are designed and constructed based on natural gas feed. Natural gas was produced as one of the byproducts of crude oil and mostly was burned. Gradually along with increasing volumes of extracted natural gas, planning on gathering and using associated gas resulted in more usage of natural gas in different sectors including petrochemical feed and fuel. Following the developments, National Iranian Gas Company (NIGC) was established in 1965 as one of the subsidiaries of the petroleum ministry with initial capital of 25 millionRials. Since its establishment, NIGC has gradually achieved capabilities and managed to have access to various sources and facilities such as experts and efficient human force equipped with scientific and theoretical vision and knowledge, tools, equipment, machinery and various advanced workshops for implementing its operations proportionate with the economic and social development trend of the country, so that it can independently accomplish all the related tasks complying with the valid international acceptable standards. Today, NIGC as one of the 4 mail subsidiaries of petroleum ministry is supplying more than 70 percent of total energy in the country as well as the feed stock for tens of petrochemical and industrial complexed around the country. The company also is operating one of the biggest high pressure gas transmission and distribution networks of the world facilitating export, import, transit and swap of natural gas in the country. In the point of natural gas treatment and supply, the company has the first position in the Middle East and one of major gas companies around the world. At the time being, the number of the NIGC permanent staff is more than19000official staff and more than 19300 total staff.

Title: Environmental Impact Assessment (EIA) Process for Sustainable Extraction of Oil, Gas and Petroleum Raw Materials and Processing Technological Systems Sustainability Excellence Achievements Abstract In this research article, strategic environmental assessment (SEA) process for sustainable extraction of oil, gas and petroleum raw materials and processing technological systems have been discussed. Strategic environmental assessment (SEA) process can be broadly defined as a study of the impacts of a proposed project, plan, project, policy or legislative action on the environment and sustainability. In this research, SEA process has been aimed to incorporate environmental and sustainability factors in to project planning and decision-making process such as project formulation and appraisal of Matsushita Carbon Company (MCC) plant in 1979 at Tada and cotton roller ginning plant as well as certain other projects that included policies, programs, plans and legislative actions. Sustainable extraction process is a kind of extraction that meets the needs of the present without compromising the ability and efficacy of future generations to meet their own sustainable extraction of oil, gas and petroleum raw materials and processing technological system needs. Environmental Impact Assessment (EIA) process can be defined as the systematic study of the potential impacts (effects) of proposed projects, plans, programs, policies or legislative actions relative to the physicalchemical, biological, cultural, and socioeconomic components of the total environmental product life cycle. The primary purpose of the EIA process is to encourage the consideration of the environment in Organizational’s planning and decision-making process (OPDM) and to arrive at actions that are environmentally compatible. OPDM process should include the integrated consideration of technical or engineering, economic, environmental, safety, and health, social and sustainability factors to achieve business excellence. Prior to the National Environmental Policy Act (NEPA) process in 1970 in the USA, technical and economic factors dominance the World’s projects. The objective of the study design conceptualization of SEA process based on fifteen number of sustainable detailed project reports (DPRs) submitted by the extension learners of Diploma in Entrepreneurship and Business Management (DEBM) course conducted by the Entrepreneurship Development Institute of India (The EDI of India) during the research year (RY) 1999 to 2019 under the author’s counsellorship.

study is cross sectional. Environmental Health Impact Assessment (EHIA) process has been conducted for projects to consider the safety and health impacts to mitigate psychological health loadings on workers and nearby residents. Social Impact Assessment (SIA) process can be defined as the systematic identification and evaluation of the potential social impacts (effects) of proposed projects, plans, programs, or legislative action such that social consideration is encouraged in OPDM process and to arrive at actions that are socially compatible. SEA process concerns to environment and sustainability effects in OPDM process and arrive at proposed projects, plans, programs, and legislative actions that are compatible with respect toenvironment and sustainability issues. International EIA process required multi-disciplinary approach that has been conducted very early stage of Japanese Matsushita carbon rod project in 1982 for strategic environmental assessment. The paper highlights SEA process conducted for certain projects such as sustainable extraction of oil, gas and petroleum raw materials and processing technological systems that based on operation and process approach and associated studies for sustainable extraction development. Engineering product environmental lifecycle analysis (LCA) has been conducted for identifying and measuring the impact of extraction of oil, gas and petroleum raw materials and processing technological systems on the environment by means of mass and energy balance methods. LCA considers the activities related to raw materials, transformation, ancillary materials, equipment, method, market, man power, production, use, disposal and ancillary equipment. As far as safety is concerned personal protective equipment and materials (PPEMs) that include garments, clothing, gloves, safety shoes, hard hats, safety glasses, shields, respirators, full aprons, safety belts, and other safety items which must be used by an individual. Such equipment is important for personal protection and for safety. It is the manager’s and supervisor’s responsibility to ensure that they are used. The enactment of worker’s compensation law and occupational disease law shall increase materially the cost of insurance to industry. The increased cost and the certainty with which it is applied will put a premium on accident-prevention work. This cost can be materially reduced by the installation of safety devices. Research experience has shown that approximately 80% of all the extraction of oil, gas and petroleum raw materials and processing technological system accidents are preventable. EIA and EHIA processes have been conducted for research projects to consider the safety and health impacts to mitigate psychological health loadings on workers and nearby residents. SEA system is a potentially useful element of good environmental management and sustainable development; however, as currently practiced in oil, gas, and pertroleum industries, it is far from perfection. Emphasis should be given in industries involving the extraction of oil, gas and petroleum raw materials and processing technological systems on maintaining economic viability of the operation, while in turn taking care to preserve the ecological and social sustainability of the country. International EIA process required multidisciplinary approach that has been conducted very early stage of Indo-Matsushita Midget electrode project in 1982 at Tada for technical, economic, ecological and social sustainability .

Title: Biogas, Renewable energy Biogas power generation at oil production unit Abstract The biogas is a renewable energy that can be used for heating, electricity, and many other operations that use a reciprocating internal combustion gas engines. To provide these internal combustion engines with biogas having ample gas pressure to optimize combustion, within the European Union ATEX centrifugal fan units built in accordance with the European directive 2014/34/EU (previously 94/9/EG) are obligatory. These centrifugal fan units, for example Combimac, Meidinger AG or Witt &Sohn AG are suitable for use in Zone 1 and 2 . Other internal combustion engines such as gas turbines are suitable for the conversion of biogas into both electricity and heat. The digestate is the remaining inorganic matter that was not transformed into biogas. It can be used as an agricultural fertiliser. Biogas plants A biogas plant is the name often given to an anaerobic digester that treats farm wastes or energy crops. It can be produced using anaerobic digesters (air-tight tanks with different configurations). These plants can be fed with energy crops such as maize silage or biodegradable wastes including sewage sludge and food waste. During the process, the micro-organisms transform biomass waste into biogas (mainly methane and carbon dioxide) and digestate. Higher quantity of biogas could be produced when the wastewater is co-fermented with other residual from dairy industry, sugar industry, brewery industry. For example, while mixing 90% of wastewater from beer factory with 10% cow whey, the production of biogas is increased by 2.5 times compared to the biogas produced by wastewater from beer factory only.

Title: Production Optimization through Gas Lift: The Challenges Abstract The driving force, which displaces oil from a reservoir, comes from the natural energy of the compressed fluids in the reservoir. This energy is known as the reservoir pressure. This pressure results from the overburden from the overlying rocks. A reduction in pressure between the reservoir and the producing facilities is required for a well to https://www.scientificfederation.com/oil-gas-petroleum-2020/program.php

produce. If this pressure difference is great enough, the well will flow naturally to the surface using only the natural energy supplied by the reservoir. However, if the pressure equalizes between the well bore and the reservoir, no flow from the reservoir will take place and there will be no production from the well. When the natural energy cannot overcome the hydrostatic head of the fluid in the tubing, the natural energy needs to be supplemented by some form of artificial lift. There are various forms of artificial lift which are continuous gas lift, intermittent gas lift, rod pump, centrifugal pumping (ESP). The main form of artificial lift this paper will focus on is the continuous gas lift. In the continuous gas lift system, gas is injected into the well at a constant rate into the tubing. The lifting effect is created by aerating the liquid, i.e. changing the density of the liquid in the tubing. Production optimization through gas lift has its own benefit and challenges which this paper will center on. The aim of this paper is to review gas lift method for production optimization and its operational challenges in mature field. The objective of this paper is to examine the different levels of gas lift optimization, assess current improvement in gas lift technology and identify key changes for the future of gas lift operations. Currently in the oil and gas industry, the discovery of huge reservoir is no longer common in many part of the world and with the tendency of oil price increasing, many operators in the oil and gas industry are increasingly investing in artificial lift method for production optimization. This paper is imperative because it will critically review the advancement and challenges of gas lift technology and also contribute to existing literatures on production optimization through gas lift.

Title: Data Analytics for Oil & Gas Exploration and Production Abstract In today’s competitive world, saving Time, reducing Cost, maintaining/ improving the Quality and Safety consideration, are crucial principles that should be realized by “Oil & Gas Industry” as one of the highest money-producing and investment industries in the world. Finding and producing Hydrocarbon is technically challenging and economically risky where this complicated process generates a huge amount of data and a great power is embedded in this data that Oil and Gas Industry can learn much from it. The amount of data one has is important, as more data leads to more understanding of the entire mechanism. However, the important takeaway of this large volume of data (Known as Big Data) is what organizations do with it. During the past decades, Energy Industry was focused on data integration to find a solution for getting all the data in one place and make it available for all the expertise working in different disciplines to find and produce Hydrocarbon. While today’s focus is on the integration and interpretation of this data (known as Big Data Analytics) which refers to a new technology being employed to handle the large datasets with the main characteristics of Volume, Variety, Velocity, Veracity and Value. Analyzed data provides insights that lead to better technical decisions mainly through improving reservoir simulation, reducing drilling time, increasing drilling safety and optimizing production rate.

Abstract Unconventional deposits are natural forms of oil that have such high viscosities and densities that they are no longer "fluid." "Unconventional" refers to naturally occurring oil or gas deposits of potentially commercial significance that are unrecoverable by conventional drilling methods. TWO main groups: Bitumen family -- Oil shale -- Oil sands Hydrates Natural gas in the presence of water at low temperatures forms clathrates and becomes effectively a solid (methane hydrates). Oil Sands (formerly “tar sands”) USGS definition: “Any consolidated or unconsolidated rock that contains a hydrocarbon material with a gas-free viscosity, measured at reservoir temperature, greater than 10,000 mPa, or that contains a hydrocarbon material that is extractable from the mined or quarried rock.” (This definition excludes coals, oil shales, and solid bitumens.) They are commonly present at shallow depths (< 600 m) and not far above major unconformities. Many deposits represent the outcropping parts of conventional oil reservoirs. Heavy oil sands contain equally heavy oil, but are exploitable with the aid of artificial stimulation - usually cyclic steam injection (steam soak) under pressure. Surface and near-surface bituminous sands Most bituminous sands are found in: ß Venezuela - Orinoco oil belt ß Alberta Athabasca oil sands ß Russia (Siberia) -- Olenek oil sands, Olenek deposits are in remote Siberia: ß Permian sandstones ß Heavy oil: 1011 m32 ß Unlikely to be exploited Orinoco oil (or tar) belt of eastern Venezuela is probably the largest continuous accumulation of oil in the world - 600 km long by ~ 50 km wide; - net pay thickness: 40-80 m - 180 and 1800 m depths - 1.2 X 1011 m3 - 6 X 1011 m3 recoverable These oils have API Gravity of 8-12°, but low viscosity - few thousand millipascal-seconds – they are heavy oil rather than “oil sands” They are exploited from conventional wells with the assistance of injected steam. Athabasca oil sands "The world's largest self-contained accumulation of hydrocarbons." It is a single, discrete accumulation in a single reservoir rock (unlike Orinoco). Oil is in Lower Cretaceous sandstones (McMurray Formation) that rest unconformably on Devonian limestones and evaporites. Characteristics of the sandstone: ß clean, well sorted (~35% porosity) ß quartzose, mainly uncemented ß 50-80 m thick ß ~20 m saturated with “tar” ß locally up to 20 wt % bitumen (outcrop richest grades) ß interstratified bitumen beds up to 50 cm thick ß Lower part of the reservoir sandstone is an alluvial complex ß Upper part consists of tidal flat and lower delta plain deposits Overall reservoir complex is therefore coastal and transgressive, mainly nonmarine, but with marine components at the top. Highest oil saturations are in fluvial and tidal channel sands The "tar" is an asphaltic residuum of about 10.5° API gravity. Oil is wrapped as a coating around individual, water-wet sand grains:3 “The extraction problem is not of getting the oil out of the sand but of getting the sand out of the oil” Origin of the oil (still not fully resolved) First described in 1884, first worked about 1921. Discussion has focused around three points: • Is the "tar" immature oil or degraded oil? • What was its source rock(s)? • How did it get into its present reservoir as a coating on its grains instead of a filling of its pore spaces? Immature oil? Ball: Highly immature "protopetroleum" lacking natural cracking to make it mature () Low level thermal maturation has been confirmed – but does not account for all the characteristics of the "tar" Corbett: Tar's state is original, and due to in situ generation by humic acids from superabundant land vegetation delivered to the coal-generating Cretaceous delta . . . (unlikely) Senile (old) oil? Most geologists consider the oil to be senile, having undergone • biodegradation (bacterial) • water washing • inspissation (drying out) • some oxidation4 Effects become more pronounced updip: from heavy oils in Cretaceous basin to https://www.scientificfederation.com/oil-gas-petroleum-2020/program.php

immobilized "tars" of the Athabasca deposit. Geochemical problems . . . -- high concentration of unstable compounds suggest that the oil in its present form has not been extensively weathered, evaporated, or polymerized. Migration and source rock problems The oil has undergone long lateral migration (÷) . . . but how much vertical migration? Early workers suggested a Devonian source rock (subcrop of Devonian shales) Gussow: oil sands are a gigantic stratigraphic trap, containing oil that had migrated from postDevonian, but pre-Cretaceous, rocks formerly occupying most of the Alberta Basin? Geochemically, oil sand oil is like other Cretaceous oils but unlike Devonian oils in the Alberta Basin -- little paraffins, more cycloparaffins and aromatics than Devonian oils Vigrass proposed long migration from Cretaceous shale sources far to the west, preferentially directed around barriers on which no Lower Cretaceous sandstones were deposited Problems … • Most post-Jurassic shales have low TOC – mainly of Type III • None of the shales in the E have ever reached generative maturity. • These shales have to have generated oil volume equivalent to all known conventional oils and have survived migration across the basin. . . ?? How did the oil migrate? Improbable: single-phase flow (too far?) continuous kerogen network Possible: micellar solution? water? (theoretically possible) What if oil is pre-Cretaceous (despite geochemical problems)? The "tar" cannot have migrated > 100 km in present state Thus inferences based on present chemistry are suspect5 Did oil originate in pre-Cretaceous source sediments in the west, and migrate towards the foreland before the first Cretaceous sediments were deposited? The truncated Devonian reservoir might then lose the oil as seepage droplets into the newly formed Cretaceous lake and shallow sea; the droplets adhered to sand grains in a developing fluvial- deltaic coastal complex, and were deposited as part of the sediment: Thus no heavy, viscous oil has "migrated". PROBLEMS! Survival of oil below an erosion surface that was developed over 150 Ma before final burial Experimentally impossible to get viscous asphaltic oil to adhere to sand grains in an aqueous environment… Recent geochemical studies (Fowler et al. 2001) • Biomarkers favour a single major source rock for all the heavy oils • Same source rock also was source of many Carboniferous, Jurassic and Cretaceous conventional oils in WCSB • Biomarkers also characterize Late Devonian – Mississippian Exshaw Formation (Bakken) • Biodegradation is variable – but increases W to E in Cretaceous • Migration may have been pre-Cretaceous in northern areas Settings for giant oil-sand deposits Reservoir sands are widespread, fluvial deltaic- coastal complexes deposited between emergent landmasses and large, offshore sedimentary basins – large source areas Between source and reservoir are extensive, interfingering, permeable carrier sandstones, little interrupted by faults The carrier beds and the reservoir bed occupy a simple homoclinal slope with updip stratigraphic convergence towards the edge of the basin. An equally widespread regional seal, commonly transgressive marine shale, must follow the extensive development of the reservoir rock. This permits long-duration, long-distance migration of the oil, focused towards a single target reservoir at the updip extremity of permeability. Migration is facilitated by an updip hydrodynamic gradient towards the foreland: If maintained, much of the oil may be driven completely out of all traps and into a tar mat at the surface6 If the hydrodynamic gradient weakens, meteoric waters encroach upon the oil-filled reservoir rock from foreland outcrops, causing degradation of the oil and sealing the accumulation with asphalt.

Title: Mature Offshore Heavy Oil Field Development Utilizing Pioneer Intervention Method. Case Study in Egypt Abstract A Pioneer Coiled tubing methodology applied to overcome production-logging challenges in mature viscous and heavy oil reservoirs drilled by horizontal/deviated wells in order to determine flow profile and zonal phase contribution to maximize the productivity from the current wells. A combination of high deviation, viscous and heavy oil was almost restricting conventional intervention in these wells - especially in flowing condition - which affected the recovery of the field. A long history of unsuccessful intervention operations is recorded. When conventional logging operations are restricted due to such friction forces. Smart E-coil (coiled tubing with mono conductor cable) was used to deploy the production logging tools (PLT and Pulse Neutron log) also to perform perforation moreover it has the capability to perform conventional coiled tubing applications as well. Shut-in and flowing surveys were performed to identify water saturation, zonal contribution, and water entry zones. The data acquired using Smart E-coil provided the zonal contribution and water saturation profile, which resulted in a clear vision to take, have better reservoir management and ways to improve field recovery. GUPCO utilized Smart E-coil as the first time in Egypt,Middle East and offshore globally, 27 successful runs in six wells were done using single reel and single power pack unit also More than 20 days working in sour wells with adequate corrosion protection finally added 2000 BOPD and Saved $ 1.6 MM (34% of the budget

Title: THE NEED FOR AN AMPLE PRODUCED WATER HANDLING IN NIGER DELTA OIL PROVINCE Abstract The Nigeriaâ&#x20AC;&#x2122;s Niger delta is one of the worldâ&#x20AC;&#x2122;s largest tertiary delta systems and an extremely prolific hydrocarbon province globally. The Niger delta region has several ecosystems that play essential role for the sustenance of the different habitats and life forms in the area. it consists of mangrove, lowland rain forest, fresh water forest, and https://www.scientificfederation.com/oil-gas-petroleum-2020/program.php

aquatic ecosystem that provide services to the indigene of the region and to the economy at large. The region is noted for its high biodiversity and abundant resources of global importance. Petroleum exploration and production in the Nigeriaâ&#x20AC;&#x2122;s Niger delta region has substantially improved the nationâ&#x20AC;&#x2122;s economy over the past decades. However, activities associated with Petroleum exploration development and production operations have local detrimental and significant impacts on the ecosystems in Niger Delta. Produced water also known as oilfields water constitutes the largest waste stream from Petroleum Production operations. They contain chemicals, oil, grease etc. which continues to receive attention because of the volume involved, cost of treatment and potential environmental implications. Multiple research reveals that produced water discharged into the environment in the Niger delta is yet to meet set stipulated standards by DPR (Department of Petroleum Resources) and EGASPIN (Environmental Guidelines and Standards for Petroleum Industry in Nigeria) for both onshore and offshore disposal as concentration of oil/grease content, salinity, dissolved oil, aromatics are often the constituents of the concern. The toxicity of produced water varies with the age of the oil well and between different operations. Also, the volume of water produced increases with the age of production. As global demand and production of fossil fuel continues to increase so do their associated environmental footprints one of which is produced water. Discharges of produced water have caused environmental pollution adverse human health effects socio economic problems and degradation of the host communities in the 9 oil-producing states in the Niger delta region. Many approaches have been developed for the management of environmental impacts of produced water discharge and several environmental laws have been institutionalized for its regulation. However, the existing statutory laws and regulations for environment protection appear to be grossly inadequate and the sustainable practices to prevent environment protection have failed to be adopted. This paper reviews the resultant effects of improper discharged constituentâ&#x20AC;&#x2122;s effluent of produced water, indicate stringent strategies for produced water handling and explore the potential of oilfield produced water to be a source of fresh water for water stressed oil producing area life Niger Delta and more importantly for safer environment.
