Support GSH Activities

Advances in computers and software

have made geophysical processing, interpreta-tion, and modeling more efficient. Unfortunately, these efficiencies have not been translated into more time for thinking and learning, interacting with our friends, or enjoying life. We have an ever-increasing number of things to do, projects to complete, deadlines to meet, and emails to return.

As the industry continues to evolve, companies are doing more work with less manpower. We find ourselves under pressure to work long hours at the office, take work home, and reduce the time spent reading journals, newsletters, or attending technical meetings. Most of us work hard to maintain a precarious balance as we go through the day — juggling all the activities that make demands on our time.

Which is why it is so important to make time for the GSH.

Title: “Prestack Depth Migration at The Frade Field, Deepwater Brazil, for High-Resolution Subsurface Characterization”

Speaker: Jennifer Lewis, Chevron

Abstract:The utility of prestack depth migrated seismic data is well-established in obviously complex geologic and geophysical environments, such as subsalt. Rising costs of data acquisition and drilling necessitate a more robust characterization of risk, and more recently the benefit of prestack depth migration has been realized in areas in which time migrated data were traditionally deemed acceptable.

Advances in computer efficiencies combined with an evolving knowledge base enable high-resolution seismic imaging techniques that preserve and recover amplitude fidelity and optimize frequency bandwidth. The resulting increased confidence in interpretation can lead to a reduction in uncertainty, impacting static and dynamic models and ultimately project economics.

The Chevron-operated Frade field in the deep water of the Campos Basin was discovered in 1986 by Petrobras, followed by a successful appraisal well in 1989. Because of technical and economic challenges, comprehensive efforts toward appraisal and development planning were not commenced until 1998 by Texaco. (Chevron merged with Texaco in 2001.) Consequently, the field’s development was delayed by more than two decades after its discovery. The Frade structure is only ~1 km beneath the seafloor, but the overlying complexities create geophysical challenges that demand a prestack depth migration: a deep incised seafloor canyon with associated buried stacked channels, shallow gas, and a laterally varying anisotropic velocity structure. Near the end of the Appraisal phase of the project, Chevron delivered a reservoir-scale prestack depth migrated dataset.

The imaging effort drove a reevaluation of the structure maps, which significantly impacted estimates of original oil in place and prompted changes to proposed development well placement. A depth migration is an inherently interpretative product, and continual and close interaction between the geologist and the geophysicist is an iterative and integral element of success. As Frade enters the Production Operations phase and offers new insight into the subsurface, the depth migration will be reworked and recalibrated to further impact business decisions.

Biography:Jennifer Lewis studied earthquake seismology and the regional tectonics of southern California at San Diego State University and graduated in 2000 with an M.S. in Geological Sciences. She immediately began her career in oil with Chevron in New Orleans working Deepwater Gulf of Mexico shallow hazards and pore pressure, analysis and modeling for prestack depth migration and VSP design, and later in Houston as the Jack/St. Malo geophysicist. Jennifer is currently with Chevron’s Energy Technology Company as a Team Leader for the Velocity Modeling Services Team, which provides geophysical support for projects worldwide.

GSH OUTREACHCOMMITTEE ACTIVITIES

by Lisa Buckner

Did you know that a few Geophysical Society of Houston/Society of

Exploration Geophsyicsts (GSH/SEG) members are actively involved in making Houston area K-12 students aware of careers in geophysics?

Every October, for several years, we have hosted a geophysics booth in celebration of Earth Science Week at the Houston Museum of Natural Science (HMNS) Family Energy Festival organized by the Houston Geological Society (HGS). We have several activities including a geo-phone plugged into a laptop computer running an oscilloscope emulation program. We ask the students to tap and knock on the table and watch the response on the monitor. The geophone also picks up the periodic firing of a nearby airgun in the Wiess Energy Hall. A volunteer explains how the airgun works and how it is used in marine seismic acquisition. Another volunteer explains the illuminated seismic section on the wall. Several hundred students

and adults participate, including Boy & Girl Scout Troops earning their Geology merit badges, local families, and tourists who just happened to visit the museum during the festival. The students earn a prize (rock sample kit and more) for visiting all of the booths. It’s fun to share our knowledge and passion for geophysics with the general public. Would you like to volunteer next time?

In January, the GSH was invited to host an exhibit booth at the annual First Colony Middle School Career Day in Sugar Land because one of their teachers was impressed by the SEG/GSH booth at the Science and Engineering Fair of Houston (SEFH) last March. GSH member volunteers Lisa Buckner, Gene Womack, and Haynie Stringer educated the 8th grade students about various careers in geophysics (not just oil & gas), global opportunities and education requirements. Interested students picked up several SEG and American Geological Institute (AGI) geophysical careers brochures. We had

the geophone and laptop setup and asked the students to stomp on the gym floor. Then we explained how the geophone works using a GSH Museum cutaway geophone. Next we explained how we use sound waves to explore for oil and gas and showed them a seismic section (lots of oohs and aahs). We demonstrated the P- and S-wave propagation using a toy spring (a generic Slinky). Afterwards, we gave a plastic toy spring provided by the SEG to each of the 172 students who watched our presentations. The school also asked us to give each student a sticker for their Social Studies Passport Book. Do you know of a school that has a career fair at which GSH might be able to host an exhibit booth?

On February 6, Bill Gafford and Lisa Buckner attended the Engineering, Science and Technology Council of Houston (ECH) Annual Retreat. Bill serves as the GSH representative to the ECH, and Lisa gave a presentation about GSH outreach activities.

If you are interested in working one or more shifts, please contact Lisa Buckner ([email protected])

The next outreach volunteer opportunity is the Science and Engineering Fair of Houston (SEFH), March 12 & 13, at the George R. Brown Convention Center. The GSH is a SEFH sponsor for the first time this year. Approximately 1000 junior high and high school students participate in the SEFH each year. We need volunteers to act as fair project judges or to work in our exhibit booth. If you are interested in volunteering as a judge, please contact Bob Wegner ([email protected]) or Bill Gafford ([email protected]). Exhibit booth volunteers will work in three shifts on Friday and one shift Saturday morning.

Earth transmission effects or external noise, this is the stuff of acquisition, processing and, ultimately, interpretation of seismic data. From time to time, geophysicists have taken a different point of view and have attempted to use interfering “noise” as usable signal with mixed results. Recently, there has been renewed interest in this topic – in particular for the case of deploying and activating multiple seismic sources that intentionally interfere with one another.

While long a topic of research and field practice for land vibrator acquisition, so-called simultaneous source (SimSrc) acquisition is relatively new to the world of impulsive sources as are commonly used for marine acquisition. Proposed and demonstrated 10 years ago, the subject of marine SimSrc has lain fallow until the recent uptake of wide-azimuth marine surveys. Typically, in a wide-azimuth marine survey, multiple marine vessels are deployed to achieve efficient acquisition and sufficient azimuth and fold. The desire to make better use of these vessels

and, at the same time, to achieve better coverage has driven geophysicists to pursue SimSrc for marine acquisition. The benefits promised by SimSrc are substantial.

Some topics under consideration are reduced shot spacing, unlimited record length, increased sampling in the azimuth domain allowing azimuthal analysis, faster acquisition (particularly for VSP), improved land acquisition with new technology derived for marine, reduced undershooting time, and other safety benefits. In this talk I will discuss the achievements of SimSrc and the challenges that remain for both land and marine if it is to become a mainstream acquisition methodology.

Biography:Craig Beasley completed B.S., M.S., and Ph.D. degrees in mathematics and then joined Western Geophysical in 1981. He served in several capacities in the Computer Sciences, R&D, and Data Processing departments, including worldwide VP of

R&D and worldwide VP of Data Processing in Western Geophysical and continued as VP, Data Processing after the formation of WesternGeco. He has received two Litton Technology Awards, a Performed by Schlumberger Silver Medal, and the SEG Award for Best Presentation, and he served as the Esso Australia Distinguished Lecturer. He received honorable mention for the Best Paper in GEOPHYSICS.

He is an Honorary Member of the Geophysical Society of Houston and Foreign Member of the Russian Academy of Natural Sciences. He has presented papers and published widely on a variety of topics, including prestack imaging, migration, acquisition, and the connections among acquisition, processing, and imaging. He served as the 2001-2002 SEG 1st Vice President and as the 2004-2005 SEG President. Currently, he is chief geoscientist for WesternGeco, a Schlumberger Fellow, and the founding chair for the Geoscientists Without Borders committee, and he continues to serve on the committee.

This is our opportunity to recognize those who have made contributions to the GSH and SEG over the past year and also over their careers. In addition, awards will be presented

for those with 25, 50 and 60 years of membership in the SEG.

GSH MUSEUM COMMITTEEDISPLAY AT SEG CONVENTION

Museum News by Bill Gafford

The GSH Museum Committee put together a very interesting and well received display

of 1920’s and 1930’s vintage geophysical equipment and documents for the recent SEG Convention in Houston. The display was part of the SEG Historical Preservation Committee booth and included the “Living Legends”. A number of contacts were made with people interested in possibly helping with the committee or possibly borrowing some of our inventory for display. We also received helpful suggestions for future displays. Some pictures of the display are

included below. Additional pictures can be found on the GSH website at gshtx.org.

Discussions are continuing with the SEG Historical Preservation Committee to coordinate efforts to share inventories of the GSH and SEG museum collections. We are currently involved in moving the items from our current storage area at the UT Bureau of Economic Geology Houston Research Center on West Little York to a nearby Fugro Data Solutions storage area. Volunteers are always welcome and needed to help with research, identification, and preparation of artifacts and documents for display.

FISHING TOURNAMENT RULES:This year’s tournament will be open to any and all GSH/HGS members and their guests. This is an Individual tournament, no team categories exist, and again, all participants are on the honor system. Please do not consider pooling your catch with someone else’s into one stringer. This is not fair to those who are fishing alone. 1. This is a Big Fish Tournament. In order to be as fair as possible to everyone, each participant may weigh their largest fish of each species on one stringer; i.e. one person cannot win multiple places for any one species in each category.2. No lunch break or breakfast is scheduled, so fix your own coffee and sandwiches if you don’t want to miss any fishing time.3. Both Live and Artificial bait are legal. Trolling, Tube Floaters, and wade fishing are all allowed. However, the use of trotlines, seines, electric telephones, dynamite, M-80’s, rotenone, spear fishing, etc. or any other means of illegal fishing is strictly prohibited. Only fish caught during the tournament hours are eligible. All fish weighed must be legal according to the laws of the State of Texas. Any person attempting to weigh a fish that is not legal will be disqualified. Fish that are frozen, gutted, or otherwise mutilated will not be eligible and the person attempting to weigh such a fish will be disqualified. GSH is not responsible for any violations or fines/actions resulting from any violations of state game laws, boating laws, or any other law relevant to boating and/or fishing. The GSH strongly encourages safe boating practices including the use of kill switches. DRINKING AND BOATING DO NOT MIX.4. Each contestant may launch and fish anywhere on the bay, as long as the Weigh-In deadlines are made at Tackle Box Storage & Fish Spot Marina. We ask all contestants, if possible, especially those weighing in fish, and the trophy winners, to remain at the Weigh-In on Saturday long enough for pictures to be taken for the follow-up GSH newsletter and HGS Bulletin5. The Tournament Chairman and Weigh-In Master who will act as judges will handle all disputes or interpretations of the rules. The decisions of the judges are final!6. Each contestant, evidenced by his entry in the tournament, does hereby release and agree to protect, indemnify and hold harmless, the Geophysical Society of Houston and Houston Geological Society, GSH/HGS organization, from and against any and all claims, demands, causes of action of any sort and damages, resulting from any accident, incident or occurrence arising out of, incidental to or in any way resulting from his participation in this tournament.

2010 SEG/EAGE

Distinguished Instructor Short CourseGeophysics Under Stress: Geomechanical Applications

of Seismic and Borehole Acoustic WavesSpeaker: Colin Sayers, Schlumberger

April 22, 2010 • WesternGeco10001 Richmond Avenue, Houston, TX 77042

Register at http://www.gshtx.org

Overview

The state of stress within the earth has a profound effect on the propagation of seismic and borehole acoustic waves. This leads to many important applications of elastic waves for solving problems in petroleum geomechanics. The purpose of this course is to provide an

overview of the sensitivity of elastic waves in the earth to the in-situ stress, pore pressure, and anisotropy of the rock fabric resulting from the depositional and stress history of the rock and to introduce some of the applications of this sensitivity. The course will provide the basis for applying geophysics and rock physics solutions to geomechanical challenges in exploration, drilling, and production. A variety of applications and real data examples will be presented, and particular emphasis will be placed on the rock physics basis underlying the use of geophysical data for solving geomechanical problems.

Whom Should Attend?The integrated nature of this course means that it is suitable for individuals from all subsurface disciplines including geophysics; geomechanics; rock physics; petrophysics; geology; geomodeling; and drilling, reservoir, and petroleum engineering. The short-course presentation, limited to one day, will provide an overview of the basic concepts and applications and minimizes the use of mathematical developments. As a result, the course presentation does not require a theoretical background and can be attended by a broad section of working geoscientists and engineers interested in applying geophysical data to the solution of geomechanical problems. The course book will provide support for the course and further extend some of the more technical considerations.

Date: Thursday, March 18, 2009Time: 5:30 p.m.Location: HESS Club 5430 Westheimer Road, HoustonSpeaker: Dr. Philip Ball, Senior Geologist GoM South Deepwater Global Exploration (GEX) North America StatoilHydroTopic: “Constraints On Continental Break-Up Within The Great Australian Bight From Seismic Reflection, Gravity And Magnetic Data Analyses”Abstract:Weakly magmatic passive margins record large amounts of extensional strain prior to breakup, but the role of magma intrusion and the along-strike variability of strain remain poorly understood. This study utilized existing onshore and offshore gravity, magnetic, seismic reflection, and well data to probe the evolution of rifting, continental breakup, and seafloor spreading across the Australo-Antarctic margins. Continental rifting along the largely non-volcanic southern margin of Australia occurred during two discrete phases, Syn-rift 1 (165-140 Ma) and Syn-rift 2 (100-83 Ma), but existing data are too sparse to map their spatial extent. The crustal thickness and structure onshore varies between tectonic domains, thinning from 35-40 km onshore to approximately 10 km beneath the magnetic quiet zone offshore. Euler deconvolution solutions calibrated with seismic reflection data reveal two discrete sub-parallel rift systems. Rift Structures of the western rift system overlap that of the eastern rift system, but they are separated by approximately 200 km. Each system terminates at or near to the boundary of the Gawler craton, suggesting that the craton served as an obstacle to rift propagation. The Ceduna sub-basin, which contains up

to 15 km of primarily post-rift strata, lies between the two rift zones. During Syn-rift II, a new rift zone developed oceanward of the Syn-Rift I along the western rift zone. Minor magmatism and possible mantle exhumation is observed during the second rifting stage and within about 10 My prior to the first well-defined seafloor spreading anomaly. The asymmetry of the conjugate Australian and Antarctic margins may be explained by the along-axis propagation of two spatially separated rifts that eventually linked via a NW-striking system of faults, or through discrete rift jumps to the NE within the rift-overlap zone. Using observations of the location and distribution of basement-related structures, a revised model for breakup between Australia and Antarctica is proposed.

Abstract:

During the past two decades or so, significant progress has been made in our theoretical understanding of the mechanical (elastic) and hydraulic (transport) behavior of fractures. On an empirical level, we have made enough observations, both in the laboratory and on real data, to be able to categorize pretty well how seismic waves behave in fractured rock. For instance, we know that the size, shape, contacts and connectivity of the surfaces of fractures are important, as are the number of fracture sets and their orientations. Geophysicists may argue that we now know enough about the seismic response to fractures and may be able to predict their presence and spatial

distribution in reservoirs. However, we cannot yet claim success in obtaining these fracture parameters from seismic data since we have not yet convinced reservoir engineers to routinely use seismically derived “fracture” parameters in their flow simulations.

In this presentation, I will review the concept of fracture prediction from seismic data, focusing on fracture modeling, and will highlight our current understanding of its limitations and the challenges ahead.

Biography:Enru Liu received his BSc in Geophysics from Changchun Geological Institute

(now Jilin University, China) in 1984 and his PhD in Geophysics from the University of Edinburgh (Scotland, UK) in 1990. Enru was Principal Research Scientist at the British Geological Survey in Edinburgh until March 2007 when he joined ExxonMobil Upstream Research Company. While at BGS, he was involved in the Edinburgh Anisotropy Project – an industry-sponsored re-search consortium. Enru is currently a research associate in the Geophysics Division of URC. He has published over 60 papers in peer-reviewed journals on seismic anisotropy, poroelasticity, multi-component seismics, and seismic fracture characterization.

DATA PROCESSING SIGDate: Wednesday March 24, 2010Time: Social 5:00 Presentation 5:30pmLocation: Fugro 6100 Hillcroft, Houston TX 77081 Speaker: Bee Bednar, Senior Executive Vice President, Panorama Technologies Inc. Topic: “How Many Beams Would a Beamer Form if a Beamer could Form Beams?”Abstract:This talk attempts to explain that mystery of mysteries loosely referred to as Beam Migration. On the one hand, Beam Migration is one of the oldest and simplest approaches to imaging seismic data ever invented. On the other hand, modern approaches and algorithms cloud Beam Migration’s simplicity, making it seem to be complex and mysterious. This presentation attempts to remove the cloud and reveal the inner practical workings

of the emerging Beam Migration methods. This includes computerized historical approaches (what I like to call hand migration); more modern raytrace based methods, including Beam Stack and Gaussian Beam methods; and finally, full wave equation “delayed” shot migration. These concepts are explained through the use of practical graphics and examples while avoiding complex mathematical or physical concepts.

Biography: After receiving a Ph.D. in Mathematics from the University of Texas at Austin, Bee did research in Anti-Submarine Warfare at Tracor and taught Mathematics at Drexel University and the University of Tulsa. He was Manager of Seismic Research at Cities Service Company and later became Manager and then Director of Geophysical Sciences at Amerada Hess, where he was instrumental in the development of distributed seismic processing software and led Amerada to the forefront of prestack beam-based depth imaging and computer-assisted interpretation. He has participated in many prestack depth imaging and interpretation projects and has published over 75

papers in Mathematics, Electrical Engineering, Geophysics, and Computer Science. After retiring from Amerada Hess he became Vice President of Research and Development at Advanced Data Solutions, where he was instrumental in introducing LINUX-based cluster computers to the energy industry. He founded 3dBee Tech in 1997 to perform consulting and geophysical software development. He is currently one of the founders of Panorama Technologies Inc., where he is Senior Executive Vice President. Bee still keeps a finger in education through Migration courses for the Society of Exploration Geophysics and Nautilus, Inc.
