Analysis of Post-Audits for gulf of Mexico Gravel-Packed Oilwell completions Leads to Continuous Improvement In Completion Practices

摘要

Final production rate alone is not an adequate measure of the success of a well completion. Rather, we must estimate the "po- tential" of a reservoir and judge the ultimate success of a comple- tion on how close we come to achieving this potential. Specific productivity indexes (SPI's) [BFPD/fit]/psi], specific injectivity indexes (SII's) [(BFPD/ft/psi), and completion efficiencies (CE's) (percent of Darcy radial flow) can be calculated at various times throughout a well completion.
