Marlin Failure Analysis and Redesign: Part 2- Redesign

摘要

This second of three related papers addresses applying the failure analysis from the first paper to the remaining Marlin wells. The fact that all five initial Marlin penetrations were predrilled up to the completion stage limited mitigation options. Within the limitations posed by predrilling, well design concepts were developed and screened using agreed-upon risk-acceptance criteria for health, safety, and environment (HSE); do-ability; and operability. On the basis of the risk profile and cost associated with each option, a vacuum-insulated tubing (VIT)/fiber-optic completion concept was selected. This paper focuses on the VIT redesign process.
