COVER PHOTO Mt. Lassen in Mt. Lassen Volcanic National Park, California. Mt. Lassen is the southernmost active volcano in the Cascade Range and is the result of subduction volcanism. At 10,462 feet, the mountain is not high in Colorado terms, but it made itself known through a series of eruptions between 1914 and 1917. A dacite on Lassen’s summit is likely the youngest rock in California . Photo is a view to the west from the Cinder Cone located in the northeast part of the Park.

RMAG December Joint Board of Directors Meeting

By Heather LaReau, Secretary (Heather.LaReau@encana.com)

On December 9th, 2011 a joint board meeting was held at the Marriott Hotel with both the incoming 2012 and outgoing 2011 RMAG Board of Directors. For me, the meeting was bittersweet! The 2011 BOD presented a summary of accomplishments, changes and areas of improvement over the past year as well as move forward items that the 2012 BOD will have to pick up and keep rolling. The 2011 BOD faced fiscal challenges without any large national events, such as AAPG conventions, to help bolster our income. However, we decided to plunge forward and run the organization on deficit budget while emplacing many changes and improvements so we are in a better position for 2012. Most notable changes with the largest impact for the organization were: 1) the new and improved RMAG website and 2) the Outcrop publication going digital, and 3) forming a sponsorship committee.

We have already seen many improvements from the website such as record breaking p u b l i c a t i o n s a l e s , i n c r e a s e s vot i n g participation, and very successful tracking of events. I believe the 2012 BOD will realize great monetary savings to the organization from the digital Outcrop and the sponsorship committee. The Outcrop did not go digital until October and therefore was unable to cut any major costs from the spending budget of 2011. Organized sponsorship solicitation will help round out and plan each events budget with monies allocated early in the year. The 2011 BOD also provided a 2012 budget for the incoming board for a guideline. All in all, the board did a very good job aligning projects, budgets and move forward tasks so that the 2012 BOD can be up and running without any lapse.

It has been a fantastic year and I look forward to seeing all of you at upcoming RMAG events!

President’s Column

By Pete Varney

90. More on that later, but first...

It’s the beginning of a new year for RMAG and the first thing I want to do is thank last year’s Board for their many contributions. Changes in 2011 included making the Outcrop digital only and welcoming in Josh as our new office manager. All of you, of course, serve the organization through your dues, committee memberships and attendance at RMAG events both social and professional. Thank you!

Three members of the 2011 board continue on in 2012 including Mark Sonnenberg as Councilor, Larry Rasmussen as Treasurer and yours truly, Pete Varney, as President. As I write this, the election for 2012 Board is in progress, so I don’t yet know who will join us but as you know, there was a fine slate of candidates willing to serve. Congratulations to those who won! For those who did not, thank you for being willing

to join the Board – and please say yes the next time you are asked to run.

While we’re talking about comings and goings on the board, I’d like to address the newer and, for the most part, younger members of RMAG. Except for the office staff your association is a 100% volunteer organization. Members run the golf tournament, edit the Mountain Geologist, determine technical and professional award winners, and much more. Please consider serving on a committee in 2012 – this is your chance to take an active part in the organization and gain knowledge about what RMAG does and how it works. Further, by serving on a committee you expand your network and develop skills that could be useful in your work. You will also bring in new ideas and perspective that could benefit the organization

President's Column

a lot going on in the DJ basin with Anadarko, EOG and others expanding development of the Niobrara/Codell in the Wattenberg – things will be interesting this year!

So, what’s that 90 all about? It is significant that 2012 marks the 90th year of RMAG. The first meeting was held in the Albany hotel on January 26th, 1922 and apparently was attended by 50 members. Back in those days the association had biweekly meetings that featured speakers on a variety of topics mostly related to petroleum. We will feature this significant milestone throughout the year. And, here is a related history fact: On April 24th, 1924, three members of RMAG helped

incorporate the American Association of Petroleum Geologists, thus starting a vital partnership that continues.

These tidbits of RMAG history come from Hal Kellog’s excellent “75 years of the RMAG” published in the Mountain Geologist, October 1997 issue.

Because I think it is important to have up to date knowledge of alternative energy sources, I’ll take advantage of this space during the year to discuss some of them, particularity from the standpoint of their true cost viz-a-viz petroleum. I think you’ll find it interesting.

That’s all for now. More in February.

in the future. Who knows...you might end up in a leadership position on the board!

I’m sure you have all heard the news. This year has the potential of being very active for the Rocky Mountain petroleum industry. The USGS has announced that according to 2008 estimates, the Bakken contains several billion barrels of technically recoverable petroleum, so I expect we will hear a lot more about the formation as 2012 unfolds.

One result is that the best place to get an oil industry job right now is North Dakota...if you like cold winters!

We are laying out plans for another Bakken symposium this year, so stay tuned for details. And then, there’s

The RMAG is pleased to announce the winner of The Mountain Geologist Best Paper Award for 2011. The winning paper is “White River Group paleosols as source rocks for uranium mineralization in western Nebraska”

by Steven S. Sibray.

This extremely well written and illustrated paper presents the geologic history of the uranium bearing White River Group sediments in western Nebraska. The author presents evidence that the uranium deposit at the Crow Butte mine occurs in the Eocene Chamberlain Pass Formation instead of the Oligocene Chadron Formation. This outstanding paper will serve as a useful guide

Smart Apps

By Cat Campbell Utah DNR Geosights

Speaking with a friend the other day, I realized just how integral our smart phones are becoming in our lives. He was explaining that while driving on vacation last week, he noticed an outcrop that could be important in some research he is doing.

Lacking his trusty Brunton, he simply downloaded an app for the compass, grabbed his strike and dip and continued home.

Smart phones can even do geology now.

The technological capabilities of our smart phones is astounding.

In order to try and stay informed, we compiled a list of a few of our favorite geologic apps currently available.

The Beetaloo Basin, Australia: The World’s Oldest Petroleum Systems?

By Thomas Ahlbrandt, Ahlbrandt Consulting, Conifer, Colorado, January 4, 2012

The basin is dominantly an oil prone (Type II kerogen) basin with about four times the resource volume potential of oil relative to natural gas although both represent very large opportunities.

The Beetaloo Basin is arguably the oldest petroleum basin in the world with source rocks dating back to 1.4 billion years (Mesoproterozoic) and contains four active petroleum systems at relatively shallow depths (<3 km); i.e. the Hayfield, Upper and Lower Kyalla and Velkerri Total Petroleum Systems across a prospective area that encompasses 7 million acres. The basin is dominantly an oil prone (Type II kerogen) basin with about four times the resource volume potential of oil relative to natural gas although both represent very large opportunities. In aggregate the four Mesoproterozoic source rock shales constitute 70 percent (2100m) of the upper 3 km of the sedimentary succession. It is part of the larger MacArthur Basin, Northern Territory of Australia, approximately 600 kilometers south of Darwin.

Eleven wells were drilled by Pacific Oil and Gas in the late 1980s and early 1990s, a subdivision of Rio Tinto, to evaluate the petroleum potential of the area following the encountering of numerous oil and gas shows in mining core holes related to sulfide mineralization in the region and all encountered numerous oil and gas shows as well as recovering relatively light oil (35-38° API) oil in several sandstone and shale horizons. Petrohunter Energy Corporation drilled the Shenandoah #1 well in the central basin commencing in 2006 and Falcon Energy deepened the well in 2009 and is currently testing the well in multiple unconventional gas accumulations.

Luncheon Programs basin that greatly modified the interpretation of the structural history of the basin.

These imbricated, westerly verging thrusts are related to a zone of transpression (relay zone) along a north south strike-slip fault created in a Mesoproterozoic rift basin.

Thermal maturity modeling using Tmax data suggest that the shales between about 300m and 1500m are in the oil window and deeper than 1500m are in the gas window. Cores from the Lower Kyalla and Velkerri shales in the Shenandoah well, although not taken in the most favorable pay intervals, are very encouraging averaging 90 scf/ton and 106 scf/ton with favorable brittleness for fracing in terms of Poissonâ&#x20AC;&#x2122;s ratio, Youngâ&#x20AC;&#x2122;s modulus and Brinnell harness and good GRI permeabilities.

The Upper Kyalla Shale has TOCs in the oil window from 2 to 3+ percent, high Hydrogen Indices (400-700 HI), and is in the oil window to depths from 500m to 1,500m and cores were bleeding oil from these intervals. The Lower Kyalla Shale contains a wet gas based on desorption analyses of cores and gas shows in the Shenandoah 1A at a depth of 1700m even though the thermal maturity (alginate reflectance equivalents to vitrintiteâ&#x20AC;&#x201D;vitrinite does not occur until the Phanerozoic) would suggest a dry gas window. The most prospective petroleum system is the Velkerri Shale, which is the major rich source rock in the basin and is as much as 800m thick. The Mid Velkerri is a 300m thick zone with TOCs commonly from 4-8% and as high as 15%, excellent Hydrodgen Indices (400-700), good secondary porosity related to calcite to dolomite cement conversion, and abundant fracturing probably related to hydrocarbon generation. The Mid Velkerri in the Shenandoah 1A well is in the dry gas window and Continued on page 18

has good desorption values, average 106 scf/ton, at a depth of about 2500m with as much as 130m of potential gas pay, which includes both shale gas and tight gas potential.

Along with these rich source rocks, still in the oil and gas windows, are a series of six sandstone reservoirs, each of which has some evidence of hydrocarbons either in the form of free oil recoveries or numerous gas shows. Reservoirs have retained good porosities (up to 20%) and permeability (up to 100 md) in the shallower reservoirs. Sandstones range up to 300m in thickness and are mostly continental or nearshore marine and have soft sediment deformation and curious trace fossils possibly the string of bead features similar to Horodyskia moniliformis or williamsii (?) are found on very shallow arenaceous shallow water substrates associated with flat crested mega-ripples, and abundant subaqueous penecontemporaneous slumps and small scale evaporite dissolution features.

the prospective unconventional oil plays (Lower Kyalla and Mid Velkerri).

In both reports, the recoverable natural gas resource potential was estimated to be 63.91 TCF of which shale gas accounted for 23 TCF, Basin Centered Gas for 39.3 TCF and the remaining 1.6 TCF in conventional gas accumulations.

In 2010, Ryder Scott (2010), estimated 38.95 BBO of recoverable

Prospective areas for oil vs. natural gas in the Mid Velkerri for example were 3.89 and 1.17 million acres respectively.

Although geologists are trained

to believe the present is the key to the past, this paradigm is seriously challenged by Proterozoic rocks.

The Proterozoic occupies nearly half of earthâ&#x20AC;&#x2122;s history, and the oceans, continents, sedimentation, life forms, rock kinetics, are substantially different than the Phanerozoic. For example, sulfate minerals such as pickeringite, voltaite, rozentite and pyrite occur in the Velkerri Shale reflecting the very different water chemistry, volcanism and tectonic plate distribution in this ancient landmass (pre Rodiniapost Columbia supercontinent).

The unconformity between the Cambrian Antrim basalt (dated to 573 Mya) and the Kyalla Shale (dated to 1.4 Ga) of some 800 million years plus is longer than the Phanerozoic so there is plenty of uncertainty about the basinâ&#x20AC;&#x2122;s history. Today the basin is a low relief area with significant dry and wet seasons hiding a buried Mesoproterozoic rift and thrust belt basin. Its great age is always a concern for petroleum preservation, but apatite fission track analyses suggest principal times of generation to be 200, 130 and 50 million years ago.

Active hydrocarbons are evidenced in the many cores, DSTs, mudlog and well log shows of the dozen wells in the basin drilled to date, as well as many shallow coreholes, which mostly penetrated the pre-rift Velkerri Shale.

The Beetaloo Basin is comparable in size to the current Bakken play in the Williston and opens a window on the little explored Proterozoic petroleum systems and basins of the world.

Are Shales Really that Dull? Shining Light into Dark Places and the Effects of Opening Pandora's Box.

By Joe H.S. Macquaker,Department of Earth Sciences, Memorial University of Newfoundland St. John's, Canada, February 15, 2012 Fine-grained sedimentary rocks are currently the subjects of great deal of research. In spite being very common they are poorly known, relative to other sedimentary rock types.

Most geologists consider them to be the product of deposition in low energy environments, and if they are source rocks, below anoxic bottom waters. Recent petrographic studies of marine mudstones have shown that they are typically organized into very thin, sharp based beds and commonly contain a wide variety of micro-sedimentary structures including: gutter casts, compacted ripples, triplet fabrics, organo-minerallic aggregates, aggregate grains and diminutive burrows. The presence of these fabrics forces a radical reappraisal of the conditions under which they were deposited and the processes responsible for organic carbon enrichment of the sediment.

Using micro textural data derived from classic fine-grained successions e.g. Kimmeridge Clay Formation, Mancos Shale, Whitby Mudstone Formation and Marcellus Shale, the sedimentological processes responsible for mudstone deposition in these units will be reviewed.

The presence of a wide diversity of micofabrics suggest that prior to being sedimented the components of the mudstones were: a) delivered to the seafloor as organo-minerallic aggregates and b) then dispersed both in bedload and as fluid mud by processes such as wave enhanced sediment gravity flows and geostrophic flows, prior to c) being burrowed by diminutive organisms that were living close to the sediment water interface. These data suggest that mudstones, and source rocks in particular, were deposited in much more dynamic conditions than most researchers have assumed, and that the deep water, predominantly low energy, anoxic model that is typically the default setting for interpreting their origin needs to be revisited.

They also demonstrate that these rocks contain a great deal of useful, but largely unrecognized stratigraphic information, and that they reward careful study.

PTTC Workshops Basic Well Log Interpretation Monday-Tuesday, January 9-10, 2012, 8:30 am â&#x20AC;&#x201C; 5 pm, Colorado School of Mines, Ben Parker Student Center Ballroom C Fee: $450, includes food at breaks, class notes, and PDH certificate Instructor: Dr. Dan Krygowski, The Discovery Group, Denver, CO

Overview: The course assumes no logging knowledge and seeks to establish an understanding of basic petrophysical measurements and interpretation techniques which can be applied to routine tasks, and upon which more complex and advanced information and interpretive techniques can be built.

Fluvial Stratigraphy Thursday-Friday, January 19-20, 2012 Colorado School of Mines, General Research Lab Conference Room Fee: $450, includes: refreshments, workbook, and PDH certificate Instructor: John Holbrook (University of Texas, Arlington)

Who should attend: Geologists, engineers, geophysicists, and other professionals engaged in production and/or exploration of reservoirs that were partly to mostly deposited by river and floodplain processes.

Objectives and content: Fluvial reservoirs abound and are an integral source of the world petroleum supply.

The primary objective of this course is to provide a primer on the range of processes that form fluvial strata and to develop from this genetic framework for assessing the stratigraphic architecture of fluvial reservoirs. The course will provide an overview of river processes and primary controls on fluvial preservation. We will use this background as a basis to explain the range of stratigraphic variations observed in fluvial strata from the bedform to the basin scale.

From this foundation, we will explore best techniques for reconstructing reservoir stratigraphy from available core, seismic, well-log and outcrop data.

Pervasive Tight Gas Reservoirs: Classroom and Core Workshop Thursday-Friday, March 8-9, 2011 USGS Core Facility, Lakewood, CO Fee: $450, includes food at breaks Instructor: Larry Meckel and John Kuhla Class will combine classroom learning with hands on work with core. The first day will be spent discussing the geology of different deposition environments and learning to recognize their log signatures.

The last day will be spent looking at examples from the Rocky Mountain basins. This 2-day course at the Denver USGS Core Facility will address some of the basic concepts and tools we use to recognize, map, and evaluate these pervasive tight gas reservoir systems. These resource plays have been around a long time (therefore lots of good data), are still being aggressively developed (downsized), and are the focus of new exploration (one very new play may well become the largest gas field in the U.S.). So even though gas prices are depressed, these plays have not gone away and are still very much on the industryâ&#x20AC;&#x2122;s radar screen.

The instructors have over 70 years of combined experience in these plays. They will address concepts, useful techniques, and problem areas on the first day via lectures and use the second day to look at a variety of outstanding cores from fields in four Rocky Mountain basins.
