Basically,how are we meeting the needs of themembership?Aneasyquestiontoask,butadifficultquestiontoanswer.Whatfactorsshouldweconsider,andhowshouldweratethosefactorstoderiveananswer?Beforeproceedingfurther,stopandaskyourself,howwouldIanswerthisquestion?
Some factors that I would consider:
Attendance at technical meetings.When considering attendance, I wouldconclude this is a positive indicatorsupporting the value of the Society.Technical breakfasts have the largestsingleattendanceofanymeeting,andthenumbersshowprogressiveincreasesovertime.Technicallunchesarenowheldattwo locations,and the totalattendanceis the largest for any meeting.

Killer whales produce whistles, clicks, pulsed calls, low-frequency pops and jaw claps for two
overlapping functions—to communicate and echolocate.
For years PGS has been communicating closely with operators in exploration basins world-
wide to help locate new prospects, to expand production from existing ones and to lower find-
ing and development costs. Recent significant successes from our depth imaging teams are
giving geoscientists clear images by using state-of-the-art migration algorithms and advanced
velocity model building workflows. To find out more about the bottom line benefits of PGS
data processing, please contact Frank Dumanoir at (281) 509-8354.

Abstract:Interpretationofaseismicvolumeforstructureanddepositionalsystemscanbeaverytime-consumingprocesswhenconductedusingtraditionalinterpretationtechniques.Traditionalsystemsrelyontheinterpretationofstructure(salt,canyons,andfaults)and stratigraphy (channels, fans, progrades, meander zones,etc.) on inlines, crosslines, and time- or depth-slices in theseismic volume. These systems typically include some 3-Dautomationintheformofhorizonautotracking.A new workflow and new interpretation techniques havebeen developed to enable “true“ volume interpretation - theinterpretation of structural stratigraphic features as complete3-Dsurfacesintheseismicvolume,whereanentiresurfaceisinterpretedatonce.Theworkflowincludesthefollowingsteps:
* Structural Interpretation: o Imaging and extraction of complete 3-D salt bodies andcanyons o Automatic extraction of fault surfaces from fault probabilityvolumes o Predictivehorizonsurfaceinterpretation* Stratigraphic Interpretation: o Creation of a stratal volume, removing all structural deformationfromthe3-Dseismicvolume o Imagingandsemi-automaticextractionof3-Dboundaries ofdepositionalsystemsinthestratalvolume o Inverse transformationof theextracted featuresback to thedomainoftheinputseismicvolume
Automatically interpretinghorizons,saltboundaries,canyons,andfaultsascomplete3-Dsurfacesinthevolumesignificantlyreducesthecycletimeinstructuralinterpretation.Thedomaintransformationofthevolume,removingallstructureincluding3-Dfaultdisplacementtocreateastructure-freestratalvolume,providesanidealviewofthedataforidentificationandextractionof depositional features as 3-D bounding surfaces. Many
depositional systems and features that would be completelymissed in the input seismic volume become visible andinterpretableinthestratalvolume.Theinversetransformationofthesedepositionalfeaturesintotheoriginalseismicvolumeallows all aspects of the interpreted geological structure andstratigraphy to be integrated into one view, leading to muchmorerapidandcompleteidentificationofprospectswithintheseismicvolume.

THE SEG AND THE GSH, THROUGH THE ROCK PHYSICS SIG, ARE PLEASED TO ANNOUNCE...
The field of rock physics represents the link betweenqualitativegeologicparametersandquantitativegeophysicalmeasurements. Increasingly over the last decade, rockphysics stands out as a key technology in petroleumgeophysics,asithasbecomeanintegralpartofquantitativeseismic interpretation. Ultimately, theapplicationof rockphysics tools can reduce exploration risk and improvereservoirforecastinginthepetroleumindustry.
Traditionally,rockphysicshasfocusedontheunderstandingofhowseismicsignatureschangeasafunctionofhydrocarbonsaturation,porosity,andpressure;withgreatbreakthroughsmade in laboratoryexperimentsand theoreticalmodeling.Today, rock physics has extended its turf and plays animportant role in the basin scale characterization of thesubsurface, being an integral part of both well log andseismic data analysis. This lecture shows the importanceand benefit of linking rockphysics to geologic processes,
including depositional and compactional trends. It furtherdocuments that lithology substitution can be as equallyimportant as fluid substitution during seismic reservoirprediction. It is important in exploration and appraisal toextrapolate away from existing wells, taking into accounthowthedepositionalenvironmentchangesaswellasburialdepthtrends.Inthiswayrockphysicscanbetterconstrainthe geophysical inversion and classification problem inunderexplored marginal fields, surrounding satellite areas,orinnewfrontiers.
