This is an issue for basically all seismic surveys, and the ability to handle unwanted multiples is important for subsequent imaging and interpretation. With the increasing demand for extracting precise information from seismic data, the ability to tackle the multiple problem will be even more important in the future. Seismic imaging techniques generally assume that the input data are free of multiples. Violation of this assumption leads to spurious images and amplitudes. Some typical problems are i) the strong multiples from subsalt reflections, ii) contamination of AVO properties due to multiple energy, iii) water bottom multiples and diffracted multiples that coincide with the reservoir image, etc. If multiples are not properly removed, they may be misinterpreted as, or interfere with primary energy. by Lisa Buckner K-12 Outreach Committee Initiatives I bet you are wondering why our society needs a K-12 outreach committee and what we hope to accomplish. In order to attract more students to pursue a college degree in geophysics or geology and then join/replace us in the oil industry, we need to spark their interest in elementary and middle school. In high school and college, they are interested in how a topic they like to study can become a career. All students need to learn the importance of oil & gas in their daily lives and thus promote a more positive image of our industry. Our committee has several initiatives targeted towards the needs of different age groups. The application of the complete method to 3-D data has not been straightforward. The major problem in 3-D SRME is the spatial aliasing caused by the large separation between receiver cables and between source lines in 3-D surface seismic acquisition. Elementary students need fun hands-on activities. Geologists give them rock samples to examine, categorize and identify. They also teach them about porosity and permeability. As geophysicists we can talk about earthquakes and how we use sound waves to find oil & gas. We do this by attaching a geophone to an oscilloscope (or a laptop with oscilloscope software). Students can tap on the table or jump to create the “earthquake”. I was the outreach chairperson for the Southeastern Geophysical Society in New Orleans for several years and they have a portable Technical Breakfast continued on page 20 President’s Column continued on page 20. The theory for 2-D and 3-D surface-related multiple elimination (SRME) was formulated by Berkhout and Verschuur at TU Delft in the early 90’s. The 2-D implementation very soon became a powerful tool in production processing, even for 3-D data. Today, most contractors have some implementation of the 3-D SRME method, and it has now become industry standard for the processing of 3-D seismic data. 2007 Honors & Awards Banquet May 3, 2007 See Page 13 for Details Inside This Issue Geophysical Auxiliary .......................... 3 Saltwater Fishing Tournament ............. 5 Museum News ..................................... 6 Membership Report ............................. 6 SIPES Announcement .......................... 6 Tury Tanner Tribute Photos ................. 9 Letters to the Editor .......................... 10 GSH Scenes ......................................

Editor’s Note 2007 Annual GSH Honors and Awards Banquet Thursday, May 3, 2007 6:00 p.m. - Cocktails • 7:15 p.m. - Dinner Presidential Address by Leon Thomsen “Applied Geophysics in the 21st Century: the Role of the SEG” Abstract: “With the end of the era of Cheap Oil in sight, the world will need applied geophysics more than ever. As the world’s pre-eminent organization of solid-earth geophysicists, the SEG will necessarily play a large role in this effort. The magnitude of the task means that the SEG will need to expand its activities substantially, to better serve its worldwide membership. I will give you a preview of some of the exciting new things that you will be seeing shortly, and of some of the challenges that we will have to overcome to bring this off.” Biography: Leon Thomsen, Principal Geophysicist at BP, holds degrees in geophysics from Caltech (BS, 1964) and Columbia (PhD, 1969). His academic career began with postdoctoral appointments at CNRS in Paris, and at Caltech, followed by tenured faculty appointments at the State University of New York at Binghamton (1972-80). His industrial career began in 1980, at Amoco’s Tulsa Research Center. In 1995, he moved to Amoco Worldwide Exploration in Houston, to help implement the ideas that he had earlier helped to invent. Following the 1999 merger, he serves in BP’s Exploration and Production Technology Group in Houston. Thomsen has lead technical development through innovation in vector seismics: polar anisotropy, azimuthal anisotropy, azimuthal AVO, converted-waves, Life-of-Field-Seismics, and pore-pressure prediction, through numerous SEG publications and presentations, and many patents. Thomsen was an early recipient (1960-64) of an SEG Scholarship. He received SEG’s Fessenden Award in 1994. He served as SEG Distinguished Lecturer in 1997 and as SEG/EAGE Distinguished Instructor in 2002. He is an honorary member of the Geophysical Society of Houston and of EAGE. He served SEG as vice president during 2003-04, and became an SEG Foundation Trustee Associate in 2004. He was appointed a foreign member of the Russian Academy of Natural Sciences, and given their Kapitsa Medal in 2004. He currently serves as SEG President.

This leads to an inadequate sampling in the crossline direction. A hyperbolic sparse-inversion solution to the crossline problem was developed at TU Delft. Although the method is an alternative to extensive inter- and extrapolation of data, this approach is numerically too costly for practical seismic processing. An early 3-D implementation of surface multiple attenuation was Shell’s proprietary code MAGIC. In this implementation, areally recorded shots are interpolated on the fly by interpolating the existing data sets. The computational effort increases with the number of shots when going from 2D to 3D, and adequate hardware is necessary. Statoil has developed a new implementation of the 3-D SRME scheme. We use an alternative formulation based on parabolic sparse inversion in the crossline direction. This leads to a highly efficient weighted least-squares solution that can be obtained in the angular-frequency domain. Consequently, the application of 3-D SRME to real-size 3-D surface seismic data sets becomes feasible, with a computational cost comparable to that President’s Column continued from page 1. of 3-D depth migration. The present 3D SRME scheme is implemented in Statoil’s in-house processing group. Biography: Roger Sollie is a geophysicist at Statoil’s Research Centre in Trondheim, currently working at Statoil’s office in Houston. Sollie received his master’s degree (1984) and PhD (1989) in theoretical physics from the University of Trondheim. After two years as a post doc in theoretical physics at Temple University and Florida State University, he joined Sintef Petroleum Research to work on applied research within geophysics and seismic methodology. In 2001 he joined Statoil, where he has been the Lead Geophysicist for Statoil’s Exploration R&D program. He started his current expat position in Houston in August 2006. Sollie is also adjunct professor in Applied Mathematical Physics at the University of Trondheim. He has published in such widespread areas as quantum physics, general relativity, hydrodynamics, as well as seismic multiple attenuation, depth imaging, and AVO inversion. 7th ANNUAL GSH/HGS SALTWATER TOURNAMENT oscilloscope. It is used at annual events like Super Science Saturday at the Louisiana Children’s Museum. Throughout the year, society members check it out for school classroom presentations and Boy/Girl Scout Troop meetings. Our committee is investigating costs for purchasing a portable system. On a larger scale, we are working with the Houston Museum of Natural Science (HMNS) to design a Houston Geoscience Center. It will be part of the new HMNS Satellite located in the former prison building in Sugar Land. We plan to model it after the SEG Geoscience Center in Tulsa, OK. A 12 channel seismic acquisition system setup around a room would make a great interactive exhibit. I’ve seen one in action. The students enjoy jumping in different parts of the room and observing the traces being generated. The center would include hands-on activities, exhibits of historical artifacts from the GSH museum collection showing the history of oil & gas exploration in Fort Bend County and at least one classroom. We will also encourage participation by HGS and other local societies. We are participating in two joint society projects. HGS is leading a committee to help develop curriculum, TEKS, professional development training course for teachers, etc. in support of the new 12th grade Earth Systems course as part of the four year science requirement of the Texas State Board of Education. The GSH, as a member society of the Engineering, Science and Technology Council of Houston (ECH), provides Science Fair judges and supports other K-12 outreach efforts. As you can see, we have many plans and could use more help. If you want to have some fun educating young minds, contact me, Lisa Buckner ([email protected]) or call (713) 609-4256.

The American Oil & Gas Historical Society will have this year’s meeting in the Oklahoma City’s historic Skirvin Hotel, May 31st to June 2nd, in partnership with the Oklahoma Energy Resources Board. The meeting’s key development goals include sharing strategies and building relationships needed to educate the public about the vital importance of our industry. The GSH provided a talk and artifacts at last year’s meeting in Wichita, Kansas. This year a bus load will visit the SEG’s Geoscience Center in Tulsa as part of a Saturday tour of historic communities and museums. More information is available at www.aoghs.org and a copy of the March THE PETROLEUM AGE at the HGS/GSH office. 713/463-9477 As to our new laptops, Bill Gafford will use one to continue his excellent picture inventory of our artifacts. Haynie Stringer, on the other hand, will build the other into a training tool capable of demonstrating a geophone or displaying film clips collected by Gene Womack and others. What talent do you have to help? If not direct help, can you influence a friend to show his proven talents? All will be needed as we progress toward a Geoscience center (hopefully associated with the Sugar Land HMNS Satellite).

Optimal use of these images requires a full understanding of the seismic imaging processes that create them, from data acquisition to the final migration. The primary objective of this course is to provide a broad and intuitive understanding of seismic imaging concepts and methods that enables geoscientists to make the appropriate decisions during acquisition, processing, imaging, and interpretation projects. Another objective is to expose the audience to current trends in imaging research and empower them to adopt new technologies quickly. Summary The course is organized in four lectures. The first lecture introduces the fundamental concepts of seismic imaging. The remaining lectures focus on the solutions to three crucial problems encountered in practical application of 3D seismic data: 1) choice of the most effective migration algorithm, 2) estimation of the velocity model, and 3) poor image quality caused by irregular and inadequate data spatial sampling and incomplete subsurface illumination. 1.

Our tournament was a morning event, family and non-GSH members’ participation were welcomed. The event is timed to precede the opening day of the Texas North and Central Zone Dove season and 219 shooters of varying abilities and ages turned out to hone their skills and have some fun. Our tournament was a success because all participating made it a safe morning - from the organizers to the cooks and individuals attending - by observing the safety procedures and taking responsibility for each other. We shot on two courses so most teams were finished by 11am and enjoying Diversified Logging’s excellent BarBQue lunch with chef Kenny Baucom’s presiding. We avoided heat stroke by having Gatorade on the course this year, although the soda supply took a beating at lunchtime. Accolades go to our best shooter, Ken Burch with a score of 49/50, to our leading lady, Gai Lynn Marshall with 37/50 and our junior champion Tyler Peterson with 24/ 50. The winning teams were the Halliburton Blasters and the BakerAtlas Leaders tieing at 225/250. In addition to prizes best shooters we awarded over 75 competitor prizes and many shooters departed prepared for Dove Season with extra shells and gear. Shooters: Foley, Landis, Gillespie, Brethauer and Lanza 8 Geophysical Society of Houston May 2007 May 2007 Thanks for a successful day go to all our sponsors, my co-chair Dietrich Landis, Jim and Jeani Harris and the staff at American Shooting Centers and Lilly at the GSH office. Our tournament this year will be on Saturday August 25th, 2007 and will commence a little earlier at 8:30am to minimize the amount of time shooters spend in the midday heat Sincerely, Alan Foley, Sporting Clays Tournament Chairman Geophysical Society of Houston 17 A Tribute to Dr. Tury Tanner ...a gentleman, a scholar, a great pioneer 16 Geophysical Society of Houston May 2007 May 2007 Geophysical Society of Houston 9 Letters to the Editor Golf Tournament and Dinner Geophysical Society of Houston from Lee Lawyer Responses to April ’07 President’s Column, “Preaching to the Choir” A note received from Elwin Peacock Lee, It seems that the companies are not encouraging employees or supporting GSH or SEG. Would it be a good starting place to contact the Chief Geophysicists, Chief Technology Officer or what ever they are called today and ask them to sponsor (push) their employees memberships. I don’t know how many companies pay for memberships now but they would know the status. Now when so many are called geoscientists it may be you will have to go to Vice Presidents of Exploration. It appears a whole new approach is needed. Times have changed for sure but I think professionals are missing a lot if they don’t join the professional societies and then participate in them. If they have to leave a company or want to become independents they will sure wish they had networked beforehand.

Signature: _______________________ Elwin Peacock GOLFERS READ CAREFULLY Elwin: You have made good points. It takes a lot of continuous effort to keep reminding people to support their local society. Each year, it seems that new effort is required, even though the benefits are obvious (at least to us). Lee No entry will be accepted until the entry form and fees are received in full. DON’T BE LATE WITH YOUR ENTRY FORMS AND FEES. AFTER THE APRIL 15th DEADLINE, THE COST PER PERSON WILL BE $150. Another note is from a “Joe Interpreter” named Greg Brown - I am sure we can all empathize with him. If you are not playing golf, but want to join your friends attending the dinner following the tournament, please send in $15.00 I had a few moments this morning and read your column (Preaching to the Choir) in the GSH bulletin. Here is a data point for you: per person to cover the cost of the dinner. Make a note at the bottom of the check “Dinner Only”. These checks should also be made payable to the Geophysical Society of Houston. * I am a 30 year active SEG member, once very engaged in the CSM Student, Casper, Anchorage, Midland, Denver and Lafayette geophysical societies * I am a registered Texas certified geophysicist * I also am heavily engaged working for an oil company in the Galleria area in GOM Production/Development geophysics as an interpreter * Often I see GSH events of interest, and want to attend: schools, meetings, SIGs. More data for filtering: * Looking at the current GSH ballot, I threw it away since I knew none of the people and did not feel qualified to vote * My work schedule and life are absolutely crammed, like most I work 10 hour days, and some weekends * Last fall I tried to attend the national SEG, registered, paid and was cancelled by my management at the last moment: other priorities * I have no transportation during work hours, taking a TREK commuter bus from Sugar Land to work * I have submitted (this week) a paper to the SEG, hoping it is accepted, and I get to present it (a long term career goal) I hope not to be again cancelled due to other priorities (wells drilling, budget, etc) * My local management is at best neutral on networking and SEG-GSH; they are all reservoir engineers, we have gantt charts, we must stay on schedule, I am doing two or three jobs at any given time—although they give supporting words, actions are otherwise—point is not all oil company management really agrees that the networking has value * These days I am approaching my mid-50s, end of career, energy levels are attenuating: the thought of driving in, fighting traffic to HGS meetings, etc. is not pleasant * At previous locations simple logistics, and momentum (everyone went to the meetings, everyone knew everyone, small town) made participation enjoyable, easier and management supported the societies. So, there is some data. Yes, I would love to participate in GSH. I could both contribute and learn and network. Nope, it does not happen for many of the above reasons. I bet I am a quite typical “Joe Interpreter”: overworked, on a rigid schedule, logistically challenged and often juggling major priorities. 10 Geophysical Society of Houston May 2007 MULLIGANS $5.00 EACH (MAX. 2/PERSON) AVAILABLE AT CHECK-IN GSH GOLF TOURNAMENT FORM You may select your own foursome, if not, you will be assigned to a group.

Winker, N.R. Braunsdorf, M.G. Kittridge and T.N. Diggs, Shell International Exploration & Production Inc. Abstract: In the Perdido Fold Belt of the Western GOM, mudrock acoustic properties are observed to change abruptly across the boundary between the Vicksburg-Jackson-Claiborne (VJC) and Wilcox Formations. Characterized by a sharp increase in bulk density and up to a 2,000 ft/s increase in velocity, this “jump” causes a sub-regional seismic event that we refer to as the “Perdido Jump”. Possible explanations for the “jump” include: 1) Changing mudrock composition associated with changing provenance, 2) Mineralogical changes in the mudrock associated with the diagenetic reaction of smectiterich Mixed Layer Clay (MLC) to illite, and 3) A change in the fluid pressure environment (i.e. higher fluid pressures in the overlying VJC mudrocks. Petrologic and x-ray diffraction (XRD) data reveal a significant change in the constituent granular and clay mineralogy across the boundary. VJC mudrocks above the transition are characterized by high percentages of volcanic ash and glass, and by low-grain density zeolites derived from local alteration of detrital glass. This supports changing provenance as the most likely cause for the “jump”. In addition, petrophysical evidence suggests that the overlying VJC mudrocks may be under-compacted. Mudrocks in this interval have an unusually high Poisson’s ratio and apparent porosities. Consequently, they are acoustically very soft and much more compressible than the underlying Wilcox mudrocks. On seismic time-slices, these mudrocks display a regular polygonal fault network that is stratigraphically constrained and regional in extent. A recent well drilled by Shell penetrated an interval located between the Oligocene age Frio sands and the sea floor. Mudrocks and marls in this interval are characterized by their relatively high Poisson’s ratios of ~ 0.45-0.47, approaching that of a suspension (0.5 by definition), high smectite content, fine-grained nature and low predicted friction angles that indicate very weak shear properties. They may, therefore, be the precursors for polygonally faulted, smectite-rich mudrocks that were first recognized and mapped in the western GOM by Charlie Winker and that also occur in similar aged marine sedimentary sections throughout the world. n Thursday, May 3, 2007, the Geophysical Society of Houston (GSH) will host its Annual Honors and Awards Banquet in the Ball Room of the Lakeside Country Club.
