Title: Noise and Multiple Attenuation whilst Greatly Preservingthe Amplitude Integrity of Primaries.

Speaker: Tony Rebec, Integrated Services, Paradigm Geophysical

Abstract:There is perhaps no greater frustration to the seismic interpreter than to have signal obscuredby noise. This is a common occurrence and many noise attenuation algorithms have beendeveloped to address it. Most methods attempt to separate the desirable signal from the unde-sirable noise, usually by making use of some transform into a domain where the signal or noiseis modeled mathematically, and the signal and noise can be separated.

Most historical noise suppression methods stop at separating noise and signal. That is, thesignal model itself is the output of the noise attenuation program. Some go slightly further by

I never had a “mentor.” At least, I neverhad a mentor in the classic sense-a singleindividual who guided and groomed me topromote my career or advancement. Nev-ertheless, I do not consider myself a self-made man of science. Many, many individu-als have guided my actions by giving meadvice, suggesting alternatives, or simplytaking me to lunch. I was not active in theSEG or my local geophysical section for thefirst decade of my career as a geo-scientistat Shell.

My first “Mighty Mini-Mentors” were mem-bers of the Southeastern Geophysical Soci-ety in New Orleans, LA. I was merely anonshore party-chief and spent a significantportion of time in the field during the late1970’s. Whenever I was in town, my mini-mentors dragged me out of my office andinsisted that I go to the society’s lunches. Inparticular, Gene Brumbaugh (later the SEGPresident 1982-83) drafted me to be a ses-sion monitor for the SEG Annual Meetingin New Orleans. I worked hard and felt likeI was part of an historic team promotingthe SEG ideals. I have been an active mem-ber of SEG and my local section ever since.

As GSH members, we all need to do whatthe SGS did for me. Many small nudges inthe right direction can give our younger geo-scientists considerable momentum. Bring an

associate to a GSH luncheon. Suggestthat everyone in your company attend theDistinguished Instructor Short Course(DISC 2004) January 13, 2005. As aquick aside, register for the DISC withthe form in this Newsletter or online atgshtx.org. The course provides geophysi-cists with a broad overview of the petro-leum systems of deep-water settings. Thecourse design allows geophysicists toquickly integrate the information intotheir daily workflow. The material pre-sented is approximately the 80-85th per-centile of available information. Lectureswill be complemented by extensive ref-

erences to key publications that geophysi-cists may use to follow up. This courseemphasizes the geologic aspects of deep-water deposits.

Not everyone will accept your invitationthe first time-but keep asking-month aftermonth. You do not have to adopt or con-tinuously mentor the careers of your asso-ciates. Recognize that your mini-mentoringwill consist of many small nudges and thatthose nudges can have a tremendous ef-fect on someone. Eventually, you will findanother you or me to be an influentialleader or future SEG or GSH officer.

According to the SEG history, the totalmembership was 14,172 during the 50thanniversary year in 1980. The AnnualMeeting registration was 12,319, an atten-dance record that has never been broken.At next year’s 2005 Annual Meeting INHOUSTON, we will celebrate the society’s75th anniversary. Start your many smallnudges now to get enough momentum tosurpass any previous records.

I have confidence that GSH members canserve as the Mighty Mini-Mentors of theHouston area for the new century.

Distinguished Instructor Short CourseHouston, January 13, 2005

Hilton Americas Houston, 1600 Lamar

OverviewThis course provides geophysicists with a broad overview of the petroleumsystems of deep-water settings. The course design allows geophysiciststo quickly integrate the information into their daily workflow. The materialpresented is approximately the 80-85th percentile of availableinformation. Lectures will be complemented by extensive references tokey publications that geophysicists may use to follow up. This courseemphasizes the geologic aspects of deep-water deposits.

SummaryThe course will start with an overview of the geology of deep-watersystems, past, present and future. This review will cover the recenttrends in deep-water in terms of drilling results, and introduce theelements of petroleum systems-reservoirs, traps, seals, source rock,migration, and timing.

The key characteristics of the key reservoir elements in turbiditesystems are: a) sheet sands (layered and amalgamated), b) channelfill, c) thin beds (overbank), and (d) slides and debris flows. The seismicstratigraphic expression of these systems is present in 2D, shallow3D, and depth 3D, and integrated with the wireline log expressionand information from outcrops, cores, and biostratigraphy. Examplesfrom several producing basins around the world illustrate these points.The production history and the reservoir challenges in developingeach of these fields is discussed.

Participants are introduced to the basic occurrences of turbidite systemsin a sequence stratigraphic framework. Examples show how to modifythe basic model for each kind of basin setting (structural setting, faults,and salt), high frequency sequences, sediment delivery systems, andthe effects of grain sizes on turbidite systems. Carbonate and lacustrinesystems are also discussed.

Many different kinds of basins produce from turbidite systems. A review ofthese basins shows the different tectonic settings and associated structuralstyles. The review also demonstrates that most reservoirs are purestratigraphic traps or combined traps. A review of seals, source rocks andmodeling principles gives the geophysicist practical techniques forunderstanding deep-water systems.

The course concludes with a summary of what is important inthe exploration for and development of deep-water systems. Theapplication of these techniques to each geophysicist’s currentprojects is key, as is the difference between frontier explorationand exploration in mature basins with deeper potential. Examplesfrom 3 or 4 basins distributed globally illustrate the principles.These examples will also demonstrate that there is deep-waterpotential in most basins globally.

Book ReportBy John Sumner

Discovery of Global Warmingby Spencer R. Weart

Could a slender book on scientific dis-covery be a thriller, a whodunit? For de-

cades we assumed that the climate was sim-ply there, in the same way that the sun risesin the east. Sure, some years might be colderor hotter or wetter or drier than others, butin the end we assumed that it all evened outand that climate didn’t really change all thatmuch over the long haul. That is not the case,as this book details.

The author follows 100 years of geophysi-cal research on climate. He draws from liter-ally hundreds of papers: meteorology, ocean-ography, ice chemistry, solar physics, pollu-tion studies, and greenhouse gases (both

naturally occurring and manmade). If thatisn’t enough, he has all those references andmore available at a website, www.aip.org/history/climate/.

It was only in the mid 1800s (thanks to LouisAgassiz) that it was finally accepted that onlya few thousands years ago vast, thick sheetsof ice covered northern Europe and NorthAmerica. Close on the heels of this knowl-edge came the desire to understand the causeof the Ice Ages. From an idea proposed in1896 that industrialization could affect theweather, this book takes us to the conclusionin the last decade that climate can change dra-matically over a period of just a few years.

Weart lays out the sophisticated and believ-able results of geophysical models that in-corporate greenhouse gases and particulatepollution into a Global Climate Model. A fi-nal chapter covers conclusions from the IPCC(Intergovernmental Panel on ClimateChange) and the refusal of the US to playany part in mitigation of the causes.

adding back a percentage of the original in-put data. Here we will show an amplitudefriendly technique to attenuate noise and mul-tiples, by taking a new approach that addsback an estimate of the signal removed dur-ing the signal modeling, rather than addingback a percentage of the original data.

This is a fundamental shift in noise suppres-sion strategies. It is an approach which is veryflexible in that it can incorporate a variety ofapplication domains, filtering tools, and newtechnologies and ways of modeling data. It isan approach which greatly improves signalpreservation, making quantitative AVO androck property analysis much more reliable. Itis a robust amplitude-preserving way to pre-condition data for pre-stack migration, avoid-ing migration artifacts and costly reruns. Theprimary amplitudes after this new approachare trustworthy, making pre-stack migrationwith AVO now a realistic option.

Biography:With over 35 years in the seismic arena TonyRebec has experience in the full spectrum ofactivities from seismic data acquisition throughto reservoir characterization. He received hisbachelor of science joint honors degree in geol-ogy and mathematics from London University.

Tony’s career started in 1967 with Geophysi-cal Services Incorporated (GSI) at their facility

in England as a processing seismologist. In1967 he accepted a position as quality con-trol geophysicist in marine acquisition work-ing in and around Africa, Australia and theFar East. After 2 years he was promoted toarea quality control geophysicist for the ma-rine operations in EAME with the prime re-sponsibility for field data integrity. Returningto processing in England he was promoted togroup leader and processing party chief priorto being appointed as processing manager fora joint venture in Stavanger, Norway betweenStatoil and the Norwegian Petroleum Direc-torate. This joint venture was later merged withthe Geophysical Company of Norway to formGECO. On returning to England he wasmade responsible for all Shell UK’s process-ing in Europe as a processing supervisor andworked on the first 3-D surveys processed inthe North Sea.

In 1978 he was promoted to a staff posi-tion at GSI’s headquarters in Dallas, Texaswhere he was responsible for worldwidetraining in marine acquisition and process-ing. In 1980 he joined Marion Bone’s 3Dinterpretation and reservoir studies groupwhere he was accountable for marineprojects. Responsibilities included hands-on3-D training schools for clients, interpreta-tion projects, geophysical reservoir studiesand the development of an early 3-D inter-active interpretation system and 3D visual-

ization technologies. This group evolved intoan integrated studies group for reservoir de-scription and 3-D reservoir monitoring forwhich he was the operations manager. In1990 the Dallas facility was relocated toHouston under Halliburton Geophysical Ser-vices (HGS) where he was instrumental insetting up Halliburton’s reservoir descriptiongroup. He was appointed to the worldwideHalliburton team for the promotion of hori-zontal drilling technologies where he was akeynote speaker for geophysics. He wasthen promoted to marketing manager forland and marine processing for HGS. In1994 Western Geophysical purchased theassets of HGS and he was positioned as tech-nical marketing and sales manager for ma-rine processing with specific focus on depthimaging until joining The Coherence Tech-nology Company (CTC) in 1995. At CTChe was VP for worldwide marketing andsales until it was acquired by Core Labora-tories in 1999 where he continued as VPfor business development.

Museum News By Tom Fulton

Joe Jones and Bill Steiner did a masterful job organizing the GSH Tennis Tournament on the afternoon of October 22 at the Chancellors Club. They were aided in forming the brackets;

with 32 players it was relatively easy to make an even division between the A and B brackets.

This was Joe’s final season as honcho of the Tournament. He says that he has been doing it forso many years that he can’t recall when he started doing it, although it may have been prior toglobal warming!

The GSH Museum has recentlytaken delivery of both a base

station Magnetometer, a Ruska por-table #4835, a tripod and a cut-awayseismometer - all in excellent condi-tion from Dick Baile. Also, a call and

visit to Turhan Taner resulted in thetrunk of my car being full of a dozenboxes of files - advertisements andtechnical papers - many from the’80s. I particularly noted a numberfrom SSC friends.

Other trivia noted. Craig Ferrisstarted the SEG Museum Committeein ’85. The Oct. ’79 GSH News Let-ter indicates that C.C. Hutchinson atthat time had chaired the GSH Mu-seum Committee for 20 years.

Title: Fluid property discrimination from the inversion of AVO attributes

Speaker: Brian Russell, Hampson-Russel Software

Abstract:This paper draws together materialfrom rock physics, AVO, and seismicamplitude inversion to discuss howfluid effects can be discriminated frommatrix effects using pre-stack seismicdata. The theory of both Biot andGassmann for porous, fluid-saturatedrocks is first used to derive a generalformula for fluid property discrimina-tion given that both the P and S im-pedances are available. This formulaallows us to decompose the P and Simpedances into a fluid term and arigidity term. We show that this for-mulation does not depend explicitlyon which set of physical parametersare used: the Lamé constants and den-sity, or the bulk and shear modulii anddensity. This method can therefore bethought of as a generalization of thelambda-mu-rho (LMR) approach.

The AVO and amplitude inversiontechniques are discussed to show howthis technique can be implementedusing pre-stack seismic data. We firstgive an overview of AVO attribute

analysis, discussing how the use ofpre-stack seismic data allows us toextract at least two independent at-tributes from our data. Althoughthere are many choices for these at-tributes, we use the AVO techniqueto extract P and S reflectivity at-tributes. We next use amplitude in-version to transform these reflectivitysections into P and S impedances.These impedance sections are thentransformed to fluid and matrix termsusing the transform previously de-scribed. The techniques are illustratedusing a shallow gas-sand examplefrom Alberta and a well log examplefrom Eastern Canada.

Biography:Brian Russell holds a B.Sc. in Geo-physics from the University ofSaskatchewan, a M.Sc. in Geophys-ics from Durham University, UK, anda Ph.D. in Geophysics from the Uni-versity of Calgary. He started his ca-reer with Chevron in 1976, andworked in both Calgary and Hous-

ton as an exploration geophysicist. Hesubsequently worked for both Teknicaand Veritas in Calgary before co-founding Hampson-Russell Softwarein 1987 with Dan Hampson. Since2002, Hampson-Russell has been afully owned subsidiary of VeritasDGC.Brian is currently Vice President ofHampson-Russell, and is based inCalgary. He is actively involved in bothgeophysical research and training, andpresents courses on seismic technol-ogy throughout the world.

Brian was President of the CanadianSEG in 1991, received the CSEGMeritorious Service Award in 1995,the 1999 CSEG Medal, and honor-ary membership in 2001. With SEG,Brian served as chairman of TheLeading Edge editorial board in1995, technical co-chairman of the1996 Denver annual meeting, andas President in 1998. In 1996, Brianand Dan Hampson were jointlyawarded the SEG Enterprise Award.
