The integrationof rock mechanics, open hole logs and seismic geophysics for petroleum engineering applications

摘要

The integration of core based rock mechanics with the open hole log and seismic geophysics technologies, has created added value through operational costs savings for Chevron's world-wide drilling and completion holdings. Early development of this integrated technology focused on supplementing core measured rock property data with open hole log measurements to obtain rock mechanical property estimates throughout the borehole. Log derived mechanical property estimates have lead to the development and world-wide use of the following applications: 1) formation drillability assessment for bit optimization and performance prediction, 2) wellbore stability for extended reach and horizontal wells, 3) sanding predictions for completion design, and 4) formation stress profiling and elastic properties modeling for hydraulic stimulation design.
