摘要

Beginning in the early 1990's, ChevronTexaco (CVX) initiated the strategy of developingmechanical earth models from acoustics dominated data volumes. The business driver was tolink the G&G disciplines involved with prospect exploration and development with theengineering disciplines involved in well systems design. This strategy has culminated inCVX's capability to build Mechanical Earth Models (MEM) from the reservoir to surface,linking earth physical properties, I.e., rheology, to the geology, seismic geophysics and in situstress character of the entire geologic section. MEMs are now being created during earlyproject stages, to provide a phased approach to asses well systems design risk. Well plannersnow use MEM volumes for bit optimization & performance prediction, wellbore stability,sand prediction, fracture stimulation design, cuttings disposal design and seismic reservoircharacterization for by-passed oil. The presentation will introduce acoustics based rockmechanics concepts, describe CVX's acoustics based rock property prediction technique, andpresent field application case histories for selected business units world-wide, includingdeepwater Gulf of Mexico, North Sea, the Arabian Gulf, offshore West Africa and Asia.
