Santos Basin, Brazil: Successful Drilling Campaign 2008-2010

摘要

The evolution in well design and continuous-improvement actions are reported for the execution of five shallow-water and deepwater wells drilled by Repsol using a third-generation semisubmersible rig during 2008-2010. As part of the continuous-improvement approach, the quality-assessment/quality-control (QA/QC) procedures were tightened throughout the campaign. The proper use of after-action reviews at the completion of each well phase was paramount for the lessons learned from each well and their application to subsequent wells.
