Joint SGS/NOGS November Luncheon Presentation

Subsalt Imaging: The RAZ – WAZ Experience Speaker: Jerry Kapoor

Abstract Is the salt winning? This was the question posed by keynote speaker Paul Singer of Total at the subsalt workshop held at the Colorado School of Mines in the summer of 2005. This was a unique workshop in that presenters from oil companies and contractors all discussed their inability to successfully image under salt rather than the success stories generally related at most conferences. It became quite obvious at the end of the workshop that the salt, indeed, was winning, and we needed a step change in technology to improve our ability to image subsalt on a consistent basis. Oil industry geophysicists stated that their exploration success in the deepwater Gulf of Mexico area was linked to our ability to image subsalt, and most of the presentations suggested that vast areas of the salt basins remained un-imaged (see Figure 1). The reasons for our inability to image subsalt on a consistent basis remained unclear. “Image under salt and reap huge rewards” provided the motivation to invest in new research and development. The deepwater subsalt play in the Gulf of Mexico is an area where the cost of drilling and development can run into billons of dollars. The complex geological structures, the presence of allochtonous salt, and wells costing 50-100 million dollars provide the economic motivation for investment in step-change technology.

Abstract Continued

This lead to the development of new acquisition techniques such as wide azimuth (WAZ) and rich azimuth (RAZ), together with more accurate velocity models and migration algorithms, to meet the demand for accurate images in Gulf of Mexico subsalt exploration areas. Several wide-azimuth-type surveys have been acquired in the last couple of years and some early processed results were shown at the 2006 SEG International Exposition and Annual Meeting by BP, Shell, and BHP. These results indicated that these types of surveys do provide a step-change improvement in subsalt imaging. The technical and financial success of these surveys has led the industry to acquire several large-scale multi-client surveys in the deepwater Gulf of Mexico salt basins. In this paper, we share experiences gained and real data examples from processing several such surveys

Jerry currently manages WesternGeco’s North America Advanced Imaging Team. He began his career with GSI in Croydon, England and has managed seismic data processing centers in Stavanger, Norway; Bedford, England; and Houston. In 1990 he began work on developing and applying technology to image steep dips and sub-salt sediments. Since 1994 he has been managing WesternGeco’s depth imaging business unit and has been involved with a number of successful complex imaging projects in the deepwater Gulf of Mexico.

President’s Corner_____________by Toby Roesler

A new style of Energy Company commercial is out on TV now showcasing the oil industry efforts to abate our dependence on foreign

oil, increase the use of renewable energy sources, lowering green house gas emissions and reverse global warming. But as we all know these new/high-tech solutions will do little to change the world in comparison to the one thing that really is the driver . . . commodity price. So those of us who are sticklers for the truth in advertising might long for oil company promotions that in affect say: the oil and gas industry wants you to know that record profits are making the world a better place . . . and you are welcome. The marketers won’t let that happen. In spite of all these great intentions and with the price of a barrel approaching the century mark, Americans still seem reluctant to car pool, drive smart cars, ride bikes, abandon drive-thru daiquiri shops, or abandon the suburbs. To date the geoscientist has done very little to help in the “greening” of America. Our esteemed colleagues at OPEC, the operators of the world’s fleet of deepwater drilling rigs, and the providers of smart completions have been doing everything in their power to get the developed world to change its thirst for oil all to no avail. Success in changing hearts and minds will require coordination and help from geoscientists. The geoscientist has not been doing his part and in fact is one of big culprits in oil and gas’s failure to turn the world “green”. Repeatedly infusing the industry with innovation after innovation, geophysics has created so much cost saving technologies that have enabled the industry to find more and more oil. I believe that the technology has gotten so good that even an interpreter with a Colorado School of Mines degree can find oil.

President’s Corner Continued

So how can we turn this trend of efficiency and cost saving around? Figure 1 (above) dramatically illustrates the failure of geoscience and hints

at what we can do about it. Figure 1 charts the daily rig rate for a state of the art deepwater drilling rig and my annual salary over my career. As one can clearly

see my salary was on par with the rig rate when I first started working in oil & gas. I worked hard, had some success and what happened? The curves diverged! So, I worked harder and had some more successes. But by this time the other curve was so far away that I couldn’t see it. Clearly I was doing something wrong. So what can we do to close this Gap (the Roesler Gap)? I don’t know the solution but all I do know is that if we can close the gap, the world will have taken a great step forward. And we would be safeguarding the world where our children’s children will live. Let’s close the Gap! Toby

Second Vice-President’s Corner by Don Dubose

Thank you all for attending our first Social Event of the year, we had 79 people attend. If you see any company representatives from the following companies thank them for their sponsorship of the House of Blues party: PGS, CGGVeritas, Diversified Well Logging, Geokinetics, GPI, SEI, Seitel, WesternGeco, Baker Hughes, eSeis, Fairfield, Geotrace and TGS. The October luncheon had 12 no shows from the confirmation reservations. Please note the SGS gets charged for these reservations. We should have a larger crowd this month with the joint SGS/NOGS luncheon, so call in early with your RSVP. Our luncheons will continue to be held at the LePavillon 2nd Floor on the second Thursday of each month through December of 2007. Make these dates on your calendar: Nov. 8 and Dec. 13. The luncheon formats will be, 11:00 check-in and socialize, lunch to be served at 1:30, meeting and technical talk at 11:55. Please try to RSPV to each luncheon by 10 am the Monday prior to each Thursday luncheon. You can do this by emailing your company representative or by sending email directly to me. You can reach me via email ([email protected]) or phone (504-592-5105). As always each SGS officer welcomes comments and suggestions. We want to make this organization the best that it can be. And your help in that is always appreciated.

November’s Mental Moment

These puzzles are intended to flex your grey-matter not to enhance your internet search skills. Try this one. How many squares can you see on a standard chess board? (Hint: a standard chess board is 8 x 8 ) If you think you have the answer, please give me an e-mail: tim.m@chevron.com------------------------------------------------ Here is the answer to the October puzzle: You have 1000 one dollar bills and pile of envelopes. Put the bills into the envelopes in such a way that someone can ask you for any amount of money from $1 to $1000 (examples - $27, $250, $833, etc.) and you can give it to them through a combination of the envelopes. What is the fewest number of envelopes you need to use and how much is in each envelope? Answer = 10 Why : The bills are distributed as 1, 2, 4, 8, 16, 32, 64, 128, 256, and 489 in the envelopes. Any amount up to 1000 can be constructed from some combination of the envelopes. ( Hmmm, related to the 2n sequence ) Tim M…
