November Newsletter

Tuesday, November 13th, 2018

Hello Everybody, with the outside temperatures becoming bearable, the economy apparently in full swing, the oil price at around $60-$70, the hurricane season almost behind us, and the mid-term election over – it seems like a great winter is ahead of us!

At the university yet another semester is coming to an end. I am currently teaching a class in Historical Geology and have just started discussing dinosaurs, which means that after their extinction only 66 Million years will be left to talk about – very little on the geological time scale. After having gone through the evolution of our planet through the past 4.6 billion years, it is always a great point of frustration not to be able to see how the story continues until our sun runs out of fuel in about 5 billion years.

Now that the 2018 GCAGS convention just ended, the call for oral and poster abstracts for the 2019 convention in Houston (10/23-10/25/2019) has opened and abstracts are accepted until March 4, 2019 (

In addition to our regularly scheduled meeting on Tuesday November 13, in which Barry Gidman will give a talk about shales, we have a second talk scheduled this month in conjunction with the UL Lafayette SEG student chapter on Friday November 30 at 1 pm at the University (Hamilton Hall auditorium 108). The speaker will be the 2018 North America Honorary Lecturer, Dr. Christine Krohn, with a talk about the fidelity of land seismic data. Since the University is closed after 1 pm on Fridays, parking on campus should not pose any problem. We will send out a reminder as time gets closer.

Finally, I would like to encourage everybody to actively participate in our society, come to our luncheon meetings, volunteer for office, help funding student lunches, or help with ideas for speakers, or short courses. We also would like to increase student participation in our meetings, but without sponsorship our finances do not allow for the support of reasonably-priced student lunches.

See you at the meeting!


Welcome back! SWLGS September lunch meeting Tuesday, September 11

Monday, September 10th, 2018

Kids are back in school, roads are crowded during the morning commute, days getting shorter, a named storm makes a near miss… I know what you’re thinking:

It must be time for our SWLGS meetings to start up again! And you’d be right. It’s tomorrow Tuesday, September 11, 11:30 AM at the Lafayette Petroleum Club. Isn’t it nice to know you can count on some things?

Have a look at the attached newsletter for the bio of UL’s newest Geology Professor and see what he’ll talk about at our meeting and then come by and meet him in person on Tuesday. Also check out the newsletter for details on the SWLGS/LGS barbecue. We’re changing it up this year. No spoiler here. Read all about it.


Technical Meeting and Luncheon, Tuesday May 8th

Thursday, May 3rd, 2018

The May SWLGS speaker is Harry Whitlow with a talk entitled “Frontier research at the Louisiana Accelerator Center:
present and future plans”. The luncheon starts on Tuesday 5/8/18 at 11.30 am in the Petroleum Club of Lafayette. Thanks for coming out!

Abstract: The Louisiana Accelerator Center (LAC) is a University Center within the Materials Research
Institute. The Centre is operates a 1.7 MV Pelletron Accelerator which focuses on to materials
research. The purpose of the presentation is to alert practicing geologists, researchers and students of
the work that is ongoing at LAC and future possibilities for investigations and research.
In the rst part of the presentation the tools and methods currently available at LAC are
outlined. These include (i) a MeV ion microprobe, (iii) a system for irradiation with ultra-low
fuxes of protons to simulate the radiation doses that are encountered space travel in Low Earth
orbit and interplanetary missions as well as proton beam cancer therapy and (iii) a system for
high flux irradiation that can be used to simulate exposure of materials to radiation from NORM
(naturally occurring radioactive materials).
The next part of the presentation will discuss some recent work on using the MeV ion microprobe
to identify different phases in metal alloys and rocks by a colocalization technique by using mercury
pathways in dental amalgams and a piece of drill core (provenance unknown) to develop the method.
The nal part will outline new tools that are planed including a unique MeV-SIMS microscope
that can will open unique possibilities for quantitative mapping of speci c inorganic and organic
molecules in geological samples.

Technical Meeting, Co-sponsored by LGS, Wednesday 3/21/2017

Thursday, March 8th, 2018

The March SWLGS speaker is Dr. Carl Fiduk with a talk entitled “A reversal in the roles of salt and sediment in the northern Gulf of Mexico: the rare effect of allochthonous salt advancement and inflation on over-pressured sediment”. The luncheon starts on Wednesday 3/21/2018 at 11.30 am in the Petroleum Club of Lafayette. Thanks for coming out!


In almost every basin in the world that contains evaporites, it is the evaporites which get deformed by sedimentation. A typical simple scenario would be for a) evaporites to be deposited, b) clastic and/or carbonate sediments to be deposited on the evaporites, and c) the evaporites to begin deforming into diapiric and then allochthonous salt features. However, it is possible for the roles of salt and sediment to be reversed. An advancing salt body can provide the load that causes deformation to underlying strata. This unusual reversal of roles has been observed and documented in the deep northern Gulf of Mexico basin. The full abstract is here: 2018 3-22 Lafayette_SaltKeel_abs_Fiduk

Carl Fiduk is an independent consultant and owner of Fiduk Consulting, LLC. Carl was previously an explorationist at Gulf Oil, BP, and Freeport McMoran, and Chief Geologist at CGG, CGGVeritas, and WesternGeco. To his clients he provides expertise on petroleum exploration, salt tectonics, marine depositional processes, basin analysis, seismic interpretation, seismic processing, and structural geology. He earned his B.A. and M.S. in geology from the University of Florida, an M.B.A. from The University of Texas
Permian Basin, and a Ph.D. in geology and geophysics from The University of Texas at Austin. He has explored in almost all the major salt basins of the world. He has published just at 100 peer reviewed abstracts/papers and is a past AAPG Distinguished Lecturer.
