Oil finally appears to have stopped its slide, now hovering between $35-$40/barrel, but much damage has been done to our industry in a short amount of time. As of 2/26/09, there are 31 active rigs in western Kansas with only 17 pending locations. Twenty-seven rigs are listed as “In Yard” and 9 are listed as “Stacked.” Almost half of all rigs in Kansas are inactive (figures courtesy of John Morrison). Prices for products and services have come down and prices will stabilize as we reach equilib-rium. There now seems to be a fairly solid floor around $35/barrel, which, even though lower than we’d like it to be,

allows us to run economics on planned exploration and pro-duction projects. Exploration activity is beginning to resume, albeit at a lower level than a year ago, and evidence suggests we may continue at this lowered pace for the remainder of the year. Our society is approaching its fourth year of existence. We have grown in membership and sponsorship. Thanks to Mary Brohammer and others who have helped to make our web-site first class and thank you for those who have served for the last two years. I would like to make a plea for you to consider becoming involved in support-

ing our society by serving in the organizational leadership. Elections will take place shortly and we need to assemble a slate of willing volunteers. Our elec-tion for new officers will be held in April and the new offi-cers will be installed to begin their service in May. So for those of you who were around in the late 60’s, if we don’t get some volunteers, you may get a letter that begins in a time tested way … “GREETINGS:”. Rick Saenger

Geophysical Society of Kansas Volume 5, Issue 2

The GSKS was provided an interesting paper on January 15, given by Joël le Calvez, Schlumberger, Dallas, TX, who presented a paper entitled, “Shaly Behaviors Revealed—Examples of Lessons Learned Using Microseismic Monitoring During Hydraulic Fracturing and Re-Fracturing.” It is highly likely that microseismic technologies will play an ever expanding role in attempting to better understand the paths taken by hydraulically induced fractures in both resource plays and other “conventional” reservoirs around the world. We have two papers scheduled for March and April 2009. First, on March 19, Bill Wepfer of Echo Geophysical, will be here to present various aspects of advanced processing, which is described be-low. Following on April 9 will be Morgan Brown of Wave Imaging Technology, who will focus atten-tion on salt related issues in the Kansas subsurface. His abstract and bio appear on p. 5. If your schedule permits, please join us for lunch at the Cantina area of the Petroleum Club at 11:30 am, just prior to the Technical Meeting. Price for lunch is $13 in advance and $15 at the door. Reservations can be made through either Dennis Hedke or Rick Saenger, ph. 316-295-4675. Technical Program location is 225 North Market, Wichita Bar Association, 1st Floor Conference Room. Program begins at 12:30 PM. If you are aware of talks that would be of interest to the Geophysical Society of Kansas, please con-tact Dennis Hedke at [email protected] or 316-295-4675. We look forward to seeing you on March 19 and April 9.

Program Chairman’s Column

“… newer ideas can rejuvenate your older seismic. … [R]evisit that seismic data with less conventional ideas, thereby generating prospects no one has ever seen before ...”

Bill Wepfer, Ph.D., Senior Staff Geophysicist, Echo Geophysical Corp.

“That data has been picked clean—there are no more pros-pects in that old seismic.” Such sentiments about vintage data don’t tell the whole story—the story of how newer ideas can rejuvenate your older seismic. Sure, you’ve tried reprocess-ing—hasn’t everybody?—but if the same well-traveled ideas are applied, it’s not surprising that the seismic results change little.

The bread and butter of many independent geologists and geo-physicists is to work an old area with new ideas, often resulting in many successful wells. Why not do the same with your 3D surveys? Why not revisit that seismic data with less conven-tional ideas, thereby generating prospects no one has ever seen before?

Two “F’s” are proposed to do just that. FreqEnhance™, a super-whitening program, helps coax more subtle anomalies out of your aged seismic, thus help-

ing you better see those by-passed prospects. Flexbinning, or bin borrowing, is a simple method for intelligently increas-ing the fold, thereby improving the data’s signal-to-noise; this often results in making pay zones more evident that were previously shrouded in seismic noise. Between the two of them—FreqEnhance™ & Flex-binning—these two processing F’s could help make your next well an A!

Biography

Bill Wepfer earned his Ph.D. in laboratory rock physics from Purdue University in 1989. Subsequently, he worked for Amoco (now part of BP) in Houston doing land AVO, ulti-mately leading a nine member technical group in this effort. Upon exiting Amoco in 1997, he joined Brigham Exploration in Austin, continuing his onshore AVO efforts. During all of this time, Bill was heavily involved in the seismic efforts, realizing that the core of the amplitude problems lay in the proper proc-essing of the problematic, low S/N land data. He left Brigham in 2000 to join Axis Geophysical (now part of GX Tech/Ion) as processing manager. Bill moved to Echo in 2004 as a senior seismic analyst.

Morgan P. Brown Wave Imaging Technology Inc.

Modeling and depth migration techniques which use the “full” wave equation have a proven robustness to strong velocity struc-ture, such as complex salt bodies in the Gulf of Mexico, and can in many cases out-perform Kirchhoff prestack depth migration or time migration. While Kansas is not normally viewed as a “sub-salt” play, from an imaging perspective, the salt collapse features found in many Kansas fields produce the velocity structure which makes depth migration in general, and wave equation depth migration (WEM) in particular, applicable.

In this talk we simulate and image—from variable topogra-phy—a 3D survey over a salt collapse feature, illustrating the effect of various survey geometries on the image quality. We'll present an

efficient and general WEM angle decomposition scheme which enables AVA or azimuth-based prospecting in areas where time imaging fails. We'll go on to take the synthetic data through multiple iterations of depth velocity model building using an ad-vanced WEM-based focusing scheme.
