“Unconventional Rocks” Recovered from the Moon during NASA’s Apollo Program


A representative of the U.S. Geological Survey is presenting on “unconventional rocks” recovered from the Moon during NASA’s Apollo Program.  The presentation begins with a newly revised video clip of the Apollo Saturn V rocket launch from Kennedy Space Center’s historic Launch Complex 39A.  Then, learn about the lunar geophysical experiments conducted on the Moon, plus the equipment and the vehicles of the Apollo Program.  After the presentation, audience members are invited to view the Moon rocks on short-term loan from NASA.
Lunar rock samples are embedded in a lucite disc, which contains all six rock types recovered from the Moon.  Moon rocks include (1) mare basalt, (2) mare regolith, (3) breccia formed by meteorite impacts, (4) regolith fragments from the lunar highlands, (5) anorthosite from the lunar highlands, and (6) lunar volcanic ash.  Additionally, meteorite samples obtained during Antarctic expeditions will also be available to view.  This lucite disc is embedded with the main classifications of meteorites, which include (1) condrite, (2) carbonaceous chondrite, (3) basaltic achondrite, (4) iron octahedrite, and (5) stony-iron pallasite.

From the President

Sam Fluckiger

It is my honor to represent you as President of the Denver Well Logging Society for the 2017/2018 term and I am privileged to work with the distinguished members of our Board of Directors whom I hope you will all have a chance to get to know and interact with throughout the year.  We have a number of exciting talks already lined up for the fall lecture series and I’m particularly excited about the joint RMAG/DWLS symposium coming up soon in September.  I see our industry going through a major transition in how we leverage technology and expertise which has created an environment where collaboration across disciplines is becoming increasingly important.  I look forward to meeting and interacting with all of you throughout the year and I am very interested to hear your thoughts on the state of the industry and how we as a society can evolve to keep pace with the changes we’re experiencing.  As such, I plan to submit a survey polling each of you on key issues and providing an open forum for feedback later this fall, the results of which will be reviewed by myself and the Board of Directors and subsequently shared back with the membership.  I encourage all of you to take advantage of this opportunity when it becomes available to make your voice heard and to help shape our society.  With that, I’m excited to welcome all of you to the 2017/2018 term of the DWLS.

Speaker Goals

To our DWLS members and welcomed guests, we continue a new luncheon speaker series with some unique topics and speakers.  Mimicking the diversity of the membership we will be trying to expose the group and guests to topics and speakers that reflect the various backgrounds that comprise our membership.  While there will have some familiar faces and topics, we will strive to introduce new, novel, and groundbreaking subjects to our membership.  We will also strive to grow our organization by attracting new members through our speaker series and workshops.  As always we welcome any and all feedback as this will help us improve our future speaker series and future workshop themes and topics.  Thank you and here is to a great luncheon speaker series.

The History of the DWLS

Have you ever pondered the extensive history of our beloved Denver Well Logging Society?  Who hasn't?  Well, I've been able to go through the entire archive of the chapter as far back as I am aware that anyone has still around.  I've tabulated the luncheon talks, all our workshops, and the Board of Directors, year-by-year, going back to 1985.  There are some gaps, but it's fairly complete.  Give it a perusal when you have the time; use the tabs at the bottom to switch views.  If you happen to have any additional information or think I have something incorrect, please let me know.

Robert M. Cluff Memorial Scholarship

For Graduate students specializing in Petrophysics and/or Reservoir Characterization

Thanks to the family and friends of Bob Cluff, long-time member and past president of the Rocky Mountain Association of Geologists, a memorial scholarship has been established in Bob’s name through the RMAG Foundation. When fully funded the scholarship will support graduate students who are specializing in petrophysics and/or reservoir characterization. Currently, with a balance of about $25,000, we seek to reach a minimum of $50,000 to maintain the fund in perpetuity and to begin offering scholarships.

We invite members of the DWLS to honor Bob by contributing to the scholarship fund. Members should also consider requesting matching funds or corporate funds from their employers to help fund this scholarship. A contribution to the RMAG Foundation Fund is tax-exempt under IRS 501(c)(3), Federal Tax ID 84-6036048. Questions regarding corporate funding may be directed to Laura Wray,
