Workshops to Improve Your Skills Beyond Resistivity

Friday, September 9, 2016, 8:30 am – 5 pm, Colorado School of Mines, Ben Parker Student Center, Ballroom C Fee: $250, includes food at breaks, class notes, and PDH certificate Instructor: Dr. Dan Krygowski, Discovery Group

The course assumes a basic understanding of common openhole logging measurements and their interpretation, and uses that working knowledge to consider the determination of formation fluid content through the equations which describe water saturation and water content (Archie’s equation and bulk volume water). The course illustrates how graphical methods that we once used to quickly determine fluid saturation and moveability (Pickett, Hingle, and Buckles plots) can now be used to determine calculation parameters for the equations, leaving the arithmetic to the hardware while the user concentrates on the interpretation of the data. Exercises provide the means to put the information shared here into practice.

Petroleum Geology for Non-Geologists

Monday, October 17, 2016, 8:30 am – 5 pm, Colorado School of Mines, Berthoud Hall rm. 243 Fee: $250, includes food at breaks, class notes, and PDH certificate Instructor: Laura Wray

In this one-day course, lectures, discussions, and exercises will focus on the manner in which geologic concepts are woven together both factually and creatively in the search for accumulations of petroleum. More specifically, the class is designed to provide an overarching summary of basic petroleum topics and how they are used in the search for oil and gas. Topics to be covered include:

Petroleum Engineering for Non-Engineers

Tuesday, October 18, 2016, 8:30 am – 5 pm, Colorado School of Mines, Berthoud Hall rm. 243 Fee: $250, includes food at breaks, class notes, and PDH certificate Instructor: Dr. Jennifer Miskimins

This one-day short course provides a broad, basic understanding of various petroleum engineering topics for nonengineers. The focus of the course is placed on the design, construction, stimulation, and production of wells. Specific topics discussed include the drilling of wells, rig types, wellbore integrity and design, completion types, casing and tubing definitions, downhole tools such as packers, formation damage, and stimulation including hydraulic fracturing. As the title implies, the course is designed for those who work in the oil and gas industry but do not have a technical background in subsurface topics. Previous attendees that have found the course useful include landmen, technicians, accountants, financiers, and field personnel.

PRESIDENT’S LETTER

By John Ladd

Ballots to come in October Oversupply is reappearing, causing a steady slide in oil prices through the second half of July, dampening the optimism many of us felt in June. It’s hard to walk down the 16th Street Mall at lunchtime without having a canvasser thrust a clipboard in my face and ask me to sign a petition to get a initiative on the ballot which would either outlaw 95% of the drillable locations in the Wattenberg Field or would hand over power to control oil and gas development to individual cities and counties, which in turn would lead to zoning ordinances that would effectively stop all oil and gas development in large parts of the state. One of the presidential candidates proposes to ban entrance into the country of all Muslims, which might have all sorts of unintended consequences on our relations with the major suppliers of oil to the world. Another embargo, perhaps? The other candidate gives wishy-washy answers when asked whether she would approve of a blanket ban on fracing, thus effectively shutting down the domestic E&P business. So many interesting things to write about, yet I have to write a column about…by-law changes!? Yes, by-law changes. It’s as if I headed off to DIA thinking I was going on a vacation to Hawaii, where the accompanying photo was taken, but then looked at my boarding pass and discovered I was booked on a flight to Indianapolis.

So why would I need to devote

one of these columns to such a dry subject? It’s simple. The Board and Executive Director are given a lot of leeway on how to run RMAG, which is probably just fine with a large majority of our members. Most don’t want to be bothered with it. However, one thing we can’t do is change the by-laws.

Why? Because it says so in the bylaws themselves. They can only be changed by the members. We can propose changes, but they have to be approved by a majority of the members in an election open to all members. So, you are going to receive an email with a ballot in early October. This ballot will have the usual listing of the candidates for open board seats, but in addition, there are going to be two initiatives to vote on, sort of like scaled-down version the ballot you will be voting on in the Presidential election, except I promise neither initiative will have anything to do about banning fracing. The first one will be concerned with updating the by-laws to reflect either how we already run our business today or how we would want to but don’t in deference to the by –laws. The second one will be about a modification to the Board structure.

The RMAG by-laws are not like the US Constitution, a bare-bones document meant to outline the basic structure of the organization.

Instead, it is full of lots of details about how the organization should be run and thus, it runs into conflict with what our needs are today. We made an attempt to modernize them a few years ago when

I served on the Board in another capacity. At that time, we focused on bringing them into the digital age, because the by-laws previously specified all sorts of things that needed to be done through the US Mail, like the annual Board elections. Basically the changes approved by members at that time added the option to use email and telecommunications for all functions that the by-laws required us to do by conventional mail. This still left a lot of other things that needed changing. For example, once upon a time, back in the early days of my career, most of the majors had large offices in Denver, the number of geoscientists employed in oil and gas here was much higher than today, and as a result, our membership was about 4000 people, double what it is now. This meant that there were a lot more volunteers available to arrange events and lots more people around willing to give presentations to the members, and believe it or not, we actually held lunch meetings virtually every week of the year. Arranging for technical talks every week was a major undertaking, so unlike now, where the monthly luncheons are handled by the Continuing Ed Committee, there was a separate Luncheon Committee to take care of the arrangements. The by-laws have a section about “Regular Luncheon Meetings” and they state that that they will be held with coordination of the Luncheon Committee Chairman. Such a position hasn’t existed for decades, so it’s sort of hard to be in compliance. Another

example is in the membership requirements. As was common with professional societies when I first started my career, they always required that someone applying for membership needed to get two or more “sponsors” who would vouch for them having the proper degrees and experience to qualify as a member. Such exclusivity has fallen out of favor, and RMAG informally stopped requiring applicants to be sponsored many years ago.

However, the rule is still in the bylaws. It would be cleaner if we just eliminated such items.

There are some outdated rules that we still do follow, mainly with regards to running the board meetings, which are subject to some regulatory oversight. For example, several years ago we added the position of President-Elect to the Board. Prior to that, a new president was elected at the end of the year and he jumped right into being President with little or no preparation. Now we have a year to understand all the issues and procedures facing the organization without the responsibility of having to make any decisions.

Much better! Prior to having this position, the 1st Vice –President was the stand in for the President in all functions, including running board meetings. Now the primary focus of that position is to help run the Publications Committee. The President-Elect is much more tuned into all the issues and has gone over the board meeting agenda with the President and the Executive Director the week prior to the meeting. Therefore this

person is in a much better position to stand in for the President.

Add to this that by tradition, we only nominate for President-Elect people who have already served on the Board in some other capacity. Therefore the President-Elect knows how board meetings typically operate, even at the beginning of their term of office. I nearly had to stick John Roesinck with running the February meeting when it turned out I had to be out of town on the day the Board meeting was scheduled, and he had been to a grand total of one board meeting. Fortunately everyone could agree on an alternate date. It would be much better if we could just turn over those duties to the President-Elect.

The second proposal has to do with making some modifications to the board structure. One of the awkward features of our current Board structure is how much turnover there is every year. Only three out of nine members on the current Board carry over onto the following year’s Board. This limits continuity and makes for a lot of work for the staff who have to get all the new members up to speed. One of the new incoming members, the President-Elect, has served on the Board before but the others may all be first-timers, as is the case this year. I have talked to several people I know who sit on other non-profit boards and all expressed amazement that we would have a majority of positions turn over every year. In order to reduce the changes, we propose that the Board be expanded by one person

Vol. 65, No. 9 | www.rmag.org

President’s Letter to a total of ten and that everyone serve a two year term.

Instead of having someone be elected as 1st or 2nd Vice President, who then serve on the board in that position for one year and then become the Publications or Continuing Ed committee chair, they will now stay on the Board the second year as well as be committee chair. For the first year, they will have the Vice-President-Elect title and will oversee some of the other committees currently assigned to the VP; in the second year, they will be the VP and will serve as Chair or co-Chair on one of the two big committees.

There will be only one two-year Councilor instead of the current two. The Secretary position will become a two year term and will be elected in alternating years with the Councilor.

You might think it is weird to have an even number of members on the board. What about tie votes? Would it lead to gridlock? In reality, we rarely have close votes on any motions.

Usually if there is disagreement about a proposed motion, we

discuss it, make some modifications to the original motion and then pass it with a unanimous or near-unanimous vote.

Plus, there are plenty of months when one board member is missing, so meeting s are already frequently run with an even number of members present, without any problems.

Just in case this isn’t enough of an explanation for you to be convinced that you should okay these changes, the current bylaws with markups showing all the changes we propose should be posted on the RMAG website by the time this column is published. Accompanying this will be a chart that Carrie Veatch has put together showing the details of the changes to the board structure and how they will be phased in over the next three years. Feel free to check out the details for yourself. I am confident that you will agree that all the changes are quite reasonable. And then don’t forget to fill out and return your ballot, which you should receive in early October.

Mineralogy Derived Brittleness from the Qemscan: Niobrara Case Study David Katz, Marshall Jung, Lyn Canter, Mark Sonnenfeld, Mark Odegard, John Daniels, Alan Byrnes, Mary Guisinger, Kim Jones, John Forster (Whiting Oil and Gas Corporation) goal of this study is to document the link between the sequence stratigraphic hierarchy and its control on the evolution of mineralogy by FEI’s QEMSCAN system, unconfined compressive rock strength, and dipole-sonic-derived brittleness for the Niobrara Formation. The Niobrara ultimately consists of a combination of sharply to diffusely bedded rocks composed of chalks to claystones with variable

The brittleness of sedimentary rocks is a critical aspect of their potential to form hydraulically stimulated fractures, resist embedment after stimulation, and thereby produce hydrocarbons over economically significant periods more efficiently. As such it is important to understand how brittle versus non-brittle rocks are organized within a play to improve the recovery of petroleum reserves by identifying higher-potential stimulation intervals.

organic matter. It is mainly calcium carbonate rich with changing concentrations of detrital quartz, clay, and organic matter that function as the main variables of the mineral brittleness index. The detrital and organic components are relatively dominant in the transgressive systems tract (TST) in the form of laminated and sharply laminated-gradational millimeter to centimeter to decimeter intervals of organic-rich chalky claystones-to-marly chalks; high resolution scanning electron photomicrographs also document that this fine scale bedding continues at the nanometer to micrometer scale. Discretely interbedded chalks and marly chalks are interbedded with marls at the cm to decimeter scale during the highstand systems tract (HST); by HST time the shorelines have been pushed landward the farthest and detrital terrestrial contribution to the marine environment has been reduced. This environment is ultimately more favorable to chalk deposition and an overall more brittle mineral assemblage. Mineral-derived brittleness logs of the Niobrara ultimately co-vary with dipole-sonic-derived rock mechanics (Young’s Modulus and Poisson’s Ratio), unconfined compressive rock strength measurements from the Equotip-Piccolo, and gamma ray values from downhole tools which in turn may be tuned to identify hydraulic stimulation targets away from cored wells.

The rockslide and avalanche mobilized 39 million 3 yd of rock and soil down 2,100 ft of elevation and caused a 3-minute seismic wave train and 2.8 magnitude earthquake. The H/L (height to length) mobility index was 0.14 and angle of reach a very flat 8 degrees. The most rapid avalanche surges overtopped a 280-ft high ridgeline at an outside bend on the west side as well as a 180-ft high ridgeline on the east side of the valley. Velocity estimates at these locations, based empirically on the overtopped ridge heights and trim lines above the pre-landslide valley floor, range from 40 to over 85 mph. Independently, USGS velocity calculations from analyzing the seismic data lie within this range of avalanche speeds.

Approximately half of the volume was

On May 25, 2014, a large rock avalanche (sturzstrom) occurred in rural Western Colorado, about 38 mi east of Grand Junction at an elevation of ~9,500 ft. The rock avalanche was initiated by a disturbed 2,900-ft wide and 900-ft deep block of Green River Formation that slipped along a preexisting landslide shear plane. As the rockmass (composed of shale, marlstone, and oil shale) rotated, the heaved and oversteepend front disaggregated and the pulverized rockmass “flowed” in discrete rock avalanche surges 2.8 mi down valley. The deposits ultimately covered nearly one square mile of the West Salt Creek valley.

incorporated into the rock avalanche. The remainder is now a half-mile-wide rotated disturbed block that slumped down to expose a 450-ft high headscarp. The backtilt of the block formed a large depression that filled to form a 420 acre-ft sag pond. Concerns were raised about the long-term stability of the existing headscarp, the instability of the rotated block, and the potential for mud/debris flows if the pond were to breach.

The first spring (2015) following the event, water drained from the pond by percolation to a natural pipe that outlets from the exposed base of the slump block.

This caused the pond level to stay within its banks. The following spring, on May 27, 2016, a landslide from the head scarp slid into the pond and displaced a wave of water that spilled over and cut a channel into the rotated block.

This event dropped the pond level about 6 ft., generating a mud/ debris flow that extended beyond the original avalanche to block Salt Creek and the county road. The debris flow bifurcated and buried two well pads in mud where there are multiple producing well heads.

From a regional perspective this landslide has prompted a need for landslide mapping and bare-earth LiDAR elevation models, caused re-evaluation of long run-out landslide morphology previously assumed to be coalesced mud flows, and consideration of the current density and siting of oil and gas well pads that may be near landslide-prone areas.

available, John & Al did an exemplary job of compiling their research efforts studying, in ascending stratigraphic order, the Dawson Formation, Wall Mountain Tuff and Castle Rock Conglomerate.

The rhyolite (Wall Mtn Tuff, 36.7 ma) building stone of the Castle Rock area was used in the construction of the Castle.

Where the rhyolite crops out on the ranch, an archeology site has been found, a rhyolite quarry where tools and tool making 29

debris show that early native Indians used the site.

The outcrops on Raccoon Knob demonstrate clearly the paleotopography that existed in the Late Eocene. Wall Mtn Tuff fills valleys cut into the Dawson.

On Cherokee Mtn, the Castle Rock Conglomerate fills a paleovalley that cut 240 feet into the Dawson. Although hundreds of feet of topography existed in the Late Eocene, the bulk of the erosion and topography of Douglas

ownership can be summarized as a ‘working, private ranch’ from 1954, when purchased by Mrs. Tweet Kimball from Charles Johnson, until 2000, when the ranch went to the Foundation.

The Castle is currently one of the private party/wedding venue sites in the Larkspur/Castle Rock area, with the Foundation managing the scientific research efforts on the geology and archaeology of the Ranch.

Through his research and collaboration with Dr. Wheeler, he has been able to identify four species of Paleocene angiosperms, the most common of which is laurel.

On our return to the Castle, the group traversed over “Eldorado”, a location of a significant number of petrified trees found in situ that was not previously known or documented. It was significant to us, as we heard our leaders discuss the discovery of Eldorado, how important it is to have contributors with scientific and technical expertise collect 31

these data. Within the near future, the Cherokee Ranch Geology Institute plans to publish, and eventually share in the public domain, the fascinating geology of this area.

County occurred in the last five million years.

Recent age dating techniques, such as Zircon Laser Ablation (ZLA), have been used on the Ranch and surrounding southern Denver Basin to refine and improve the stratigraphic interpretations. The Institute is working with the University of North Carolina on the dating. The ZLA helps to make a strong case that the Castle Rock Conglomerate contains lithofacies derived from both the southern and northern Front Range. The 1080 ma Pikes Peak Granite comprises the western Front Range provenance, whereas granites coming from the northern Front Range, specifically the Routt Plutonic Suite (1,700 ma) and the Berthoud Plutonic Suite (1.400 ma), have also been identified within the Castle Rock Conglomerate. The Institute is combining the ZLA information with petrography, field work, and paleocurrent directions. Mega trough cross-strata are well displayed on Cherokee Mtn. Although the day was quite warm, the leaders provided numerous stops and a wonderful alcove for shade for our lunch stop. Following lunch, the group was able to meet a third member of the Cherokee Ranch staff, Tom Michalski, who has looked at the internal architecture of the petrified wood samples from the Ranch and researched their botanical similarities to modern trees, utilizing the expertise of Dr. Elizabeth Wheeler, faculty

LEAD STORY

WSGS Publishes Updated Oil and Gas Map of Wyoming

Data about Wyoming’s oil and natural gas resources is depicted in an updated map published today by the Wyoming State Geological Survey (WSGS).

The 2016 Oil and Gas Map of Wyoming replaces the 2012 version through a collaboration between WSGS oil and gas scientists and geographic information systems (GIS) specialists.

“The map is designed to provide a general reference of Wyoming oil and gas activity through 2016,” says Rachel Toner, oil and gas geologist for the WSGS. With Wyoming ranked fifth in natural gas production and eighth in oil production nationwide, the Oil and Gas Map of Wyoming is one of the WSGS’ most popular products and is used by industry, policy makers, researchers and the public.

Because the paper map is a static snapshot of the oil and gas resources in the state, the WSGS in July launched a new

OUTCROP | September 2016

interactive, online version of the map that can be updated more regularly as new information is acquired. The online map is proving to be just as popular as its print counterpart, with more than 400 users the first week it became available to the public.

“Although the Survey is moving away from paper maps and toward having them available electronically, there is still a demand for the printed version of the Wyoming Oil and Gas Map,” says Tom Drean, WSGS director. “Many tell us that they want the paper copy for a quick reference or as an office decoration.”

Information portrayed on the map about oil and gas fields includes their reservoirs and predominant reservoir ages, field status (abandoned, shut-in, undergoing enhanced oil recovery), production information and whether a field is used for disposal purposes. The map also shows pipelines provided by the Wyoming Pipeline Authority, oil refineries, gas processing plants For more and general geologic information base layers. please contact: Compared to the previous map version, geolChristina George ogists updated the field (307) 766-2286 x231 boundaries, field attrichristina.george@wyo.gov butes and added new designations such as whether helium or carbon dioxide

Editor’s Note: Although the Lead Article for this month’s Outcrop is short and sweet the data you’ll find in the hyperlinks throughout may serve very useful to small operators on a tight budget. In many states this data would be largely inaccessible but the Wyoming State Geological Survey has done a great job of providing data to the public. With shapefiles, paper maps, and high resolution .pdf’s there’s something for everyone on the Wyoming State Geological Survey’s website.

Final steps in the project involved several rounds of cartographic editing to ensure proper label placement, symbology, reference documentation and map layout.

The map (series 103) is available to download free of charge, and printed copies are available for purchase via the WSGS Online Store. A shapefile of the 2016 field polygons is also available for download from the Survey website.

is produced from a field or used for Class I and Class V disposal (based on allowed waste injection). Oil- and gas-related facts for each basin were also updated.

The updates to the map data required extensive research into oil and gas wells, past Wyoming Geological Association field descriptions and field statuses and production. This data was incorporated into an ArcGIS model designed by the WSGS. The model automates the oil and gas field polygons and their attributes, a major difference from
