The author presented to SIPES on helium in southeastern Colorado as recently as 2022. This presentation is is an outgrowth of continued research, and is reoriented away from discussion of principles and systematics, which are well covered in the literature and were pursued at the recent RMAG Helium Conference. Instead, in this presentation I will explore the detailed geology of five or six helium occurrences in the southern Rockies that are  interesting, at least to me. These examples demonstrate a variety of geological sources and traps for helium, from a giant CO2-dominated anticlinal pool in Wyoming to an active helium-bearing, but non-producing hydrothermal system in Colorado, with other occurrences thrown in for good measure.


Today’s speaker is known to many of you. Ed Coalson was schooled in geology at Cal State Long Beach and the University of Wyoming in the 1960’s. Intense re-education came in the 1970’s and 1980’s at Amoco Production Company and Davis Oil Company in Denver. A vanity Ph.D. came in 2012 from the Colorado School of Mines. After working for several Denver independent oil and gas companies, he currently provides consulting geology and petrophysics for Desert Mountain Energy, a helium-exploration company with operations centered in the Holbrook Basin of Arizona.

Houston Chapter Luncheon @ Petroleum Club of Houston
Jun 15 @ 11:00 am

The Society of Independent Professional Earth Scientists (SIPES) presents:

Big Escambia Creek Field Escambia County, Alabama

Date: Thursday, June 15th, 2023
Time: Wine served at 11:00 am  |  Lunch & Lecture starts @ 11:30 am to 1:30 pm
Venue: Petroleum Club of Houston, 1201 Louisiana St, Houston, TX 77002


Big Escambia Creek Field was discovered by Exxon in 1972. Production began in 1974 and full field development was underway. Production is found between 15,500’-16,000’. The field has produced 1.1 TCF and 70.7MMBC. Original bottom hole pressure was 7500# and dew point pressure was 2700#. Dew point pressure was crossed in the early 90’s and since then the GOR has not risen appreciably. This presentation will offer a theory as to why.

Wichita Chapter SIPES Meeting @ Zoom
Sep 12 @ 12:30 pm

Wichita Chapter SIPES Meeting Announcement

Presenter: Robert Bryce    

Author, podcaster and film maker. Based in Austin, Texas, he writes about varying energy issues, including nuclear energy, natural gas and wind power.

Please join us on Tuesday, September 12th, 2023 for a virtual meeting beginning at 12:30 p.m.

A Sober Look At The Energy Transition

Politicians, climate activists, and media outlets are claiming that an “energy transition” is underway and that one day soon, our economy will be fueled solely by renewable sources like wind and solar. Well-funded advocacy groups are pushing regulations to ban natural gas and “electrify everything,” including our cars and trucks. In this talk, author, podcaster, and film producer Robert Bryce will deliver a sober look at the energy transition. He will discuss the labor, land use, and geo-political barriers to these all-renewable schemes and explain why energy transitions occur over decades, not years. He will show why hydrocarbons will continue powering our economy for decades to come and provide ideas and numbers that will help industry leaders prepare for the future.


Thomas Pronold is inviting you to a scheduled Zoom meeting.

Topic: Robert Bryce Energy Transition

Dallas Chapter SIPES Meeting @ Prestonwood Country Club
Sep 19 @ 11:30 am

Date: Tuesday, September 19, 2023

Place: Prestonwood Country Club – 15909 Preston Road, Dallas, TX 75248

Time: 11:30 A.M. (dining at 11:45 A.M.)

Topic: A New Economic Yardstick for Today’s Late-life Production: Holdback
Low-rate, late-life producers figure prominently in the portfolios of most oil companies, but they also create a unique financial trap for their owners. Decades of delayed plugging has accumulated liabilities while production and cash flow have tapered down. Combined these make it possible for cash-flowing properties with a positive present value to be net liability instead of an asset. This presentation explains the unexpected, the dangers it creates, and how to foresee the trap.
Speaker: Dwayne Purvis, Purvis Energy Advisors
Dwayne Purvis, P.E. has spent two and a half decades in reservoir engineering and executive leadership as a consultant and operator. He has led or participated in hundreds of field studies and reserve analyses over dozens of basins in the United States and abroad, and he has participated in the sale or acquisition of projects valued from tens of thousands to billions of dollars. Before starting his own consulting practice in 2015, he served Jetta Operating Company as Reservoir Engineering Manager and Reserves Manager. Prior roles include founder and Executive Vice President of consulting firm The Strickland Group and partner at Cawley, Gillespie & Associates, and he currently serves as an adjunct professor at Texas Christian University. Mr. Purvis has published on issues of shale reservoirs, decline curve analysis, reserves, and risk analysis. He is a registered professional engineer in the state of Texas, member of SPEE, AAPG, SEG, SIPES and a 25-year member of SPE.
