摘要

Pioneer Natural Resources’ multi-discipline DeepwaterExploration Operations team recently planned and operatedthe company’s first deepwater (4946’ WD) GOM well, Argo#1, using a Life Cycle Analysis (LCA) planning process. Asthe closest offset well was 25 miles distant it was imperativeto mine the maximum amount of pre-drill information fromthe pre-stack seismic data set.The team wanted a 3D seismic-based platform that wouldgenerate multi-discipline output for use throughout planningand drilling of the well. Of particular importance was theneed for a tool that could be used onsite for real-timelithology, porosity, and fluids correlation and pore pressureand fracture gradient prediction. The multi-discipline solutionswere provided in SEGY files for the Geophysical andGeological (G&G) team members and graphical documentsfor the Drilling/Completion & Reservoir team members.The seismic-based platform offered by the service providerwas used successfully to plan, drill, and evaluate the well forthe AFE’d cost. The service company provides two processes:The first process, DrilSeis, is a new, fully automated prestackseismic velocity extraction algorithm that generates porepressure and fracture gradient volumes.The second process, LithSeis, is a pre-stack seismic-basedpetrophysical analysis that yields lithology, porosity, andpossible hydrocarbon accumulations. LithSeis was used to aidin the confirmation of the prospective zones and to screen theshallow sediment section for possible “shallow water flow”SWF and shallow gas zones.1 Also, the pre-drill seismic porepressure and petrophysical analysis (lithology, porosity, andfluids) provided the operator with the G&G and Engineeringdata that supported the approval from the MineralsManagement Service (MMS) to eliminate the 20” conductorcasing resulting in significant cost savings. The seismicsolutions platform enabled the multi-discipline team toconduct cost-effective deepwater drilling operations.
