As we look back upon 2010, I would like to take the opportunity to recognize Beth Anderson. Beth stepped into the role of WGA office manager in 2010, coming “on board” halfway through the planning of the Annual Field Conference. Things were a bit overwhelming, to say the least. Beth stepped up and was a huge help in the planning for the Conference. Since then, Beth has been instrumental in the daily operations of the WGA, and things have really shaped up! Thank you Beth, you are truly appreciated! I would also like to thank Steve Reid for his service to the WGA. Steve may not be the first person to serve on the Board more than once, but he is the first to serve a second term as President. I admit that I would be much more nervous taking on the role of President if I hadn’t been on the Board with Steve and benefited from his mentorship. His experience with the WGA is a huge asset and I don’t plan on allowing him to go into WGA retirement as long as I am on the Board. Thanks, Steve! One final note: we will be honoring another group of 50- and 60-year members at the Friday luncheon on January 28th.

Discovery of the giant Prudhoe Bay field in 1968 by ARCO and Humble led to an agreement among these companies and BP to propose and study an 800 mile, 48” pipeline to the ice-free Valdez marine terminal. A federal right-of-way was issued in 1974, and construction began. Hundreds of hungry stateside geologists headed north for jobs involving geohazard and geological mapping, environmental studies, well site geology, and foundation engineering support. The smart geologists skipped geology and joined a union. Even the lowest paid union laborers earned 2-3 times more than professional geologists. Construction was completed in 1977 by the Trans Alaska Pipeline System (TAPS) at a cost of $8 billion ($28 billion 2010). Crossing three mountain ranges and 800 rivers, it was the largest privately funded project ever. Eleven pump stations with four pumps each operated at 1180 psi and 2 million BOPD throughput. By 1981, 2 billion BO were shipped. In 2002, an M7.9 earthquake on the Denali Fault caused only minor pipeline damage and no spillage. New life was breathed into the pipeline in 2002 when the USGS reported NPR-A reserves of 10 billion BO based on extrapolations from the Alpine Field discovery. By 2009, 15 billion BO had been loaded into 20,000 tankers. In October 2010, the USGS struck a blow to the pipeline’s future by downgrading NPR-A reserves by 91% to 896 million BO. Currently there are four operating pump stations with a throughput of less than a million BOPD. TAPS predicts the pipeline can physically operate until 2035. Minimum throughput rates of 200-300 MBOPD are needed for economic operation. The pipeline’s economic future may lie with ANWR, whose development potential and timing are uncertain.

The Cretaceous Mowry Shale is a prolific source rock for quite a few of the Cretaceous reservoirs in many Rocky Mountain basins, including the Big Horn Basin. A few 1980 vintage wells have been completed out of the Mowry Shale as a bailout zone because of the shows seen while drilling through it. In the Powder River Basin there was more production encountered in vertical wells, but once again mainly as a bailout after conventional reservoirs proved nonproductive. Recently the Mowry Shale has been the subject of several concerted exploration programs over the last couple of years in the Powder River and Big Horn Basins. Recent horizontal drilling in the Powder River Basin has had mixed results. Newer technology application along with an understanding of the play concept can be expected to result in better commercial results.

The Mowry is a siliceous shale that ranges in gross thickness in the Big Horn Basin from 250 to over 400 feet. Amorphous silica content ranges from 45% to as high as 70%. There are areas in the basin where very fine grained turbidites are interbedded with siliceous shales in the Mowry. TOC content ranges from 1.1% to as high as 4.0%, but there is a relationship between lower TOC values and higher thermal maturity. There are both type II and type III kerogens present in the Mowry.

The 2008 USGS evaluation of the Big Horn Basin describes the Mowry as a possible basin centered oil accumulation. Overall reservoir characterization for the basin centered Mowry is slightly different than the areas that have historically produced from the Mowry in the basin. Within the hydrocarbon generation window, expulsion microfractures contribute to the overall matrix of reservoir pore space, along with interparticle porosity and “large crack” fracture porosity. Horizontal drilling with effective completion technology will be key to making this play commercially successful.

HONORING THE OLDHONORING THE OLDHONORING THE OLDHONORING THE OLD----TIMTIMTIMTIME MEMBERS OF WGAE MEMBERS OF WGAE MEMBERS OF WGAE MEMBERS OF WGA

The group being honored here today as 50- and 60-year members of the WGA can probably remember what our Rocky Mountain basins looked like at that time. A series of oil and gas producing anticlinal traps located around the margins of basins; Lance Creek, Big Muddy, Salt Creek in the Powder River Basin; Dallas, Derby, and Circle Ridge in the Wind River Basin; LaBarge, Hatfield and Lost Soldier in the Green River Basin; Rangely and Parker Dome in the Piceance Basin; Big Sheepherder structures all around the Big Horn Basin; little production in the Denver and Williston Basins.

Stratigraphic traps came on slowly. Weimer’s Patrick Draw and Lawson’s Grieve discoveries were significant field developments and provided new stratigraphic concepts for geologists to pursue. Seismic helped define the interior of the basins and the stratigraphic condition and potential traps. Now, fracking and horizontal drilling.

Geologists had trouble selling stratigraphic prospects to managements who had been schooled on structural closures. An example: After the Grieve discovery Forest Oil’s management, Clayton Dorne and Bill Miller, were pressing for another big discovery and Don Lawson and I put together a fake prospect based on Grieve geology – clearly a stratigraphic trap. They threw us out of the office. “No one would drill a prospect like that.”

We had to move through acceptance of stratigraphic traps and the central Denver and Powder River Basin oil production got us started. The Wamsutter gas picture and the Williston Basin oil play are big time now. (Jack Parker really discovered the Williston play – the technology and oil price weren’t ready then.) Shale gas and oil are coming on. It remains to be seen if technology and price are ready.

(Bill Curry, (Skip’s father), who discovered the Big Muddy field, knew natural gas was very common and used to say gas was “still being generated.” He had drilled the Niobrara.)

Hello!

My name is Barb McGavern-Atkinson and I am excited to be your new WGA newsletter editor for 2011.

I am a geologist at Trihydro Corporation and have been a member of WGA since moving to Wyoming in snowy February 2007. It took me nearly 20 years to make the West my home, and I’ve finally arrived and love it!

MMMMEMBERSEMBERSEMBERSEMBERS’ C’ C’ C’ CORNERORNERORNERORNER With each new year… and each new volume of the newsletter, have you ever stopped to realize:

The average age of our WGA membership spans nearly seven decades?

As a result, we have an abundance of life-long professional experience, expertise, and just plain good ol’ story-tellin’ … right at our fingertips!

Do you know that there are many mid-professionals and junior or younger members of WGA who appreciate this fact and would value the mentorship and fellowship of our more senior geologists?

You may not be the best professional speaker … and you may not be the best professional technical writer … and you may not be the most comfortable at telling your story, summarizing your research, explaining your professional opinions ……. But you have true experience in your field, you have thoughts to share, guidance to offer, and stories that need to be heard. Why not share them? Consider being a Friday luncheon speaker for WGA, and tell YOUR story. Your fellow members would truly appreciate it.

Similarly, how may of you younger members, just entering college or, perhaps, recent graduates, realize how the fast-paced changes in modern technological aspects of geological science may have quickly left some of us older geologists (i.e., those of us who have long since graduated) in the dark?

Why not be a luncheon speaker, as well? ...Present your thesis or doctoral research, ask opinions, provide new insight and theories, tell YOUR story, too?

As mentioned previously in the editor’s note, this WGA newsletter is YOUR newsletter; you, the members, make WGA what it is: the largest, most active and successful geological association in the USA! We are eager to hear what you have to say!

Stromatolites, during life, are mounds; with high tides or storms, they become covered with sediment and, subsequently, will grow a new layer of bacteria on top (continual growth).

When stromatolites are fossilized, erosion eventually uncovers them to give a flat cross-section-like appearance. Stromatolites are rather rare today, but at various ages in the past they were very common. It may be misleading to think of stromatolites as organisms. Geologists actually refer to them as a sedimentary structure. Photo/source: www.geology.com

Answer (from p 9): One of the principal facilities at risk during the 1989 to 1990 eruptions of Redoubt Volcano was the Drift River Oil Terminal located at the mouth of the Drift River, 35 km (22 mi) northeast of the volcano. This aerial view, looking southwest, shows the 1.9 billion barrel capacity oil storage tanks. Redoubt Volcano is on the skyline at left. Photograph by R. McGimsey, U.S. G. S., April 13, 1990.
