Title:Crosswell Seismic Profiling: The DecadeAhead

Speaker:Jerry M. HarrisSEG/AAPG Distinguished Lecturer

Abstract:For many years crosswell seismic

profiles (XSP) has promised high-reso-lution images for purposes of reservoircharacterization and monitoring. De-signed to fill the gap in coverage andresolution that exists between surfaceseismic and borehole logs, the crosswellseismic profile has overcome numeroushurdles in technology development, op-erations, and commercialization.

PRELIMINARY INTERPRETATION OFFALCONTM AIRBORNE GRAVITYGRADIOMETER (AGG) BASS STRAITSURVEY

By Yi Zeng and Marion Rose ,BHP Billiton Exploration and MiningTechnologies, Melbourne

Speaker:Peter Diorio, BHP Billiton World Explo-ration Inc., Toronto

ABSTRACT:A FalconTM AGG survey was flown

over an area in the Gippsland Basin inBass Strait, Australia in July 2002. Thehigh-resolution survey covered an areaof approximately 35 by 40 km, centeredon the Marlin and Snapper gas fields.Products from the survey include grav-ity (gD), vertical gravity gradient (GDD) andaeromagnetic total magnetic intensity.

The purpose of this survey is to testFalconTM AGG over a petroleum envi-ronment. This area is consideredsuitable†since it is a significant petroleumbasin, and more importantly the surveyarea is over part of a 3D seismic surveyin which marine gravity was also beingacquired. The survey examines the con-sistency between FalconTM gD and bothsatellite and marine gravity survey resultsand examines improvement in resolu-tion Falcon data can achieve. In addi-tion, good seismic coverage assists in

interpreting the data and determiningthe source of observed features.

Biography:Peter Diorio graduated from

Carleton University in 1976 with a BSc(Hons) in Geology and Physics. Hestarted his career in 1976 as a geophysi-cist with Sander Geophysics Ltd. thenjoined Utah Mines Limited in 1980.There, and subsequently with BHP Min-erals, he was responsible for geophys-ics on wide range of base metal, pre-cious metal and diamonds projects inNorth America and overseas. He is cur-rently Research Application Geophysi-cist with BHP Billiton and is based inToronto. He is a member of the SEG,ASEG, KEGS and PDAC.

Title:Stress-induced anisotropy and its effecton AVO modeling

Speaker:Shiyu Xu

Summary:In a recent rock physics study,

anomalously high Vp/Vs ratios wereobserved relative to expectations in un-consolidated reservoir sands at shallowburial depths. For the wet sands, the Vp/Vs ratios were high relative to the sur-rounding shales. The wet sands also hadhigh Vp/Vs ratios relative to laboratorymeasurements. For gas sands, the Vp/Vs ratios observed in logs were high rela-tive to laboratory measurements of drysamples. For oil sands, the observed Vp/Vs ratios were high relative to predic-tions using existing rock physics mod-els.

The observed behavior cannot beexplained using factors such as poros-ity, lithology, clay content, pressure, tem-

perature, compaction or cementation.However, the observed behavior can beexplained as a result of stress-inducedanisotropy. Since the vertical stress isnormally much higher than the horizon-tal stresses in a relaxed sedimentary ba-sin, the compressional wave is fast inthe vertical direction, but the shear waveis slow. This consequently gives high Vp/Vs ratios in the vertical direction.

A rock physics model that includesthe effect of differential stress was ap-plied to compute anisotropic elastic pa-rameters. Preliminary results show thatits effect on Vp/Vs can be bigger thanthe fluid effect (oil versus gas). The modelhas also been applied to two deepwaterwells. We observed significant improve-ment in S-wave log prediction and in thepredicted AVO behavior compared tothe observed seismic response.

BiographyShiyu Xu is currently a senior re-

search specialist at ExxonMobil Up-stream Research Company. Shiyu Xugraduated from Imperial College, Lon-don, with an M.S. in Exploration Geo-physics and a Ph.D. in Applied Geophys-ics and Petrophysics. From 1991 to1997, he worked for the London Uni-versity Seismic Lithology PredictionConsortium, sponsored by oil and ser-vice companies. In 1998, Shiyu joinedMobil Research Company in Dallas as asenior staff geophysicist. After themerger, he joined ExxonMobil UpstreamResearch Company in Houston as aspecialist in rock physics. His researchinterest includes rock physics, seismicidentification of reservoir fluid andanisotropy.

is crosswell technology today and howis it being used? In this talk, I’ll reviewthe recent history and the state-of-the-art of modern crosswell seismic profil-ing. I’ll cover the major aspects of dataacquisition techniques, data processingfor velocity, attenuation and reflectivity,and image interpretation. Is the prom-ise realized? I’ll attempt to answer thisquestion with case studies from reser-voir imaging and process monitoringstudies. Finally, I’ll use this recent expe-rience to identify some possible futureapplications of crosswell seismic profiles

to problems found in natural resourcemanagement, groundwater systems andgeotechnical engineering.

BiographyJerry M. Harris received the Ph.D.

degree in electrical engineering fromCalTech in 1980. He worked on atmo-spheric attenuation of microwaves forthree years, then after completing thePh.D. he joined Exxon Production Re-search Company. At Exxon he workedon adaptive seismic beam steering andpolarization methods for use in areaswith seismically poor data. He moved

to the Standard Oil Company (later BP),where he developed crosswell technolo-gies for reservoir imaging. In 1988 Dr.Harris joined Stanford University wherehe is currently Professor and Chairmanof the Department of Geophysics. In1992, Professor Harris foundedTomoSeis Corporation (now a part ofCoreLabs) to commercialize crosswellseismic profiling. His current researchinterests include experimental methodsin high-resolution borehole geophysics,seismic attenuation, and acoustical reso-nance spectroscopy.

new reserves in the deepwater GOM isoften hampered by extensive salt cano-pies, sheets and other salt bodies thatabsorb or redirect seismic energy, result-ing in poor seismic imaging. Interpreta-tion of base of salt and sub-salt struc-tures can be extremely difficult. Factorsaffecting sub-salt imaging are steep dipsof the edges of salt bodies, rugose topof salt, salt structures with embeddedsediments, multiples and velocity insen-sitivity. Sediment velocity floods, saltvelocity floods and PSDMs are used inan attempt to overcome the salt ambi-guity. The use of Full Tensor Gradient(FTG) data in conjunction with seismic

interpretation and processing has provenextremely effective.

Full Tensor Gradient data representthe first derivative of the gravity (vector)field, and describe the spatial rate ofchange (of the vector field components)in all three dimensions. Gradiometerdata differ in many aspects from con-ventional high-resolution gravity databecause of increased bandwidth, reten-tion of high frequency short wavelengthsignal (generated by shallow to interme-diate geologic features), and muchgreater resolution. These factors enableits incorporation in the seismic interpre-tation at a prospect level.

Speaker:Fred Aminzadeh

AbstractWe describe the concept of meta-

attributes and their use in ‘seismic ob-ject’ detection. Meta attributes are anaggregation of a number of attributeswhere the interpreter’s insight andpower of a trained neural network arecombined to detect a particular seismicanomaly. Among the seismic objects wedetect are gas chimneys, faults, fractures,sand channels and salt bodies. We alsouse the neural network platform to inte-grate geological and pertophysical data(logs, cores), geologic knowledge (inter-preted horizons and stratigraphic se-quences) with seismic and other data.Non-linear interrelationships betweenvarious data types and reservoir proper-ties are defined implicitly at the naturalscale levels by the integration frame-work. Seismic character, in conjunctionwith acoustic and elastic impedance isused for horizon based facies analysis,reservoir characterization, hydrocarbondetection, and volume-based porosityestimation, and reservoir fluid/lithology

prediction. Meta Attributes are used todetect seismic bodies.

Biography:Fred Aminzadeh is president and

CEO of dGB-USA, a company that pro-vides services and software for quantita-tive seismic interpretation, stratigraphicanalysis, seismic inversion, and neuralnetworks-based reservoir characteriza-tion and seismic object detection.Aminzadeh previously worked forUnocal with both technical and manage-ment responsibilities. He has a Ph. D.from USC. His thesis dealt with theanalysis of layered earth media.Aminzadeh was a vice president of theSociety of Exploration Geophysicist for2001-2002. He is a member of Rus-sian Academy of Science, a member ofAzerbaijan Oil academy, and NationalResearch Council’s Committee on Seis-mology. He has three patents and anxtensive list of publications in diverseareas including nine books such as thoseon Reservoir Characterization, Petro-leum Geology of South Caspian Basin,3-D Seismic Modeling Advances in Seis-mic Data Processing, Geophysics forEngineers, and Petroleum Industry Ap-plications of Pattern Recognition.
