cluster is using the ‘Early Development Facility’ (EDF) concept to accelerate production from the key Sadad North, Hawqa and Asfoor projects. Although Sadad North was only discovered in March 2015, strong co-operation between Exploration and the cluster resulted in a field handover within six months and to date over one million barrels of oil have already been produced. With the ‘EDF’ track being actively progressed, it is envisaged that the field will be delivered without a cash loss to PDO. This is a significant achievement, especially during times of uncertainty surrounding oil price developments. The accelerated development at Hawqa field from 2022 to 2018 should result in a net present value of US$500 million. Another critical success factor is that the existing stock of over 800 wells is well managed through focused integrated well and reservoir reviews. Daily monitoring of the production performance through Lean principles using the NIBRAS exception-based surveillance tool has resulted in eliminating unnecessary time wasted on checking the wells, enabling immediate reaction to issues or opportunities. Furthermore, the expansion of the scope for hydraulic fracturing across several fields, turning the long-term closed-in wells into a valuable asset by intensive reviews and open-ups, and focus on the artificial lift system, have resulted in a significant increase to annual No Further Action (NFA) production and field management. The cluster NFA decline was arrested from around 10% to 6%, resulting in an NFA production increase of 4,000 bpd at a low UTC of around US$5 per barrel. The growth of production and number of wells is linked to the execution of several projects, such as the Greater Rima project, which has led to the de-bottlenecking of the oil pipeline water disposal capacities. New pipelines were also built from Thuyfut all the way to Rima station, which also had its capacity upgraded. Three new stations are going to be operational within the coming two years; Zauliya gas plant (ZGP), Hawqa EDF and SDDN EDF. The fast-tracked engineering project is a key enabler in reaching the cluster’s potential as PDO’s top performer by 2021.
Bahja Rima Cluster
Bahja North & South Studies
BAHJA RIMA, WHICH HAS MORE THAN SEVEN BILLION BARRELS OF OIL IN PLACE, HAS ALREADY RECORDED A 30% INCREASE OVER A TWO-YEAR PERIOD WITH THE ADDITION OF A HUGE VOLUME OF HYDROCARBON RESOURCES Hamed said: “The huge growth of well stock, increase in oil and gross production, and rise in hoist and rig activities are placing a huge challenge on the Operations team which is doing a tremendous job. “Our success did not come by luck, but by using the strength of our people and giving them the right space to put their technical thoughts and creativity into action. Doing things differently, challenging the obvious and taking calculated risks have been key success factors. “The Hawqa and Asfoor appraisals, Zareef low resistivity pay projects, Zauliyah fracking and SDDN production through the well test unit are examples of success by doing things differently. We are now referring to Bahja Rima as ‘The Land of Diamonds’!”
