Optimizing Well Design with MPD and IME: A Case Study from Offshore Mexico

Abstract This paper presents the application of Managed Pressure Drilling (MPD) techniques and the Influx Management Envelope (IME) methodology in an offshore well in the Mexican Gulf of Mexico (GoM). Drawing on insights from SPE/IADC-200509-MS, SPE/IADC-200504-MS, and SPE/IADC-200514-MS, an adaptive casing design was implemented to address uncertainties in pore pressure (PP) and fracture gradient (FG). This approach facilitated deeper casing points, enhanced decision-making, and improved influx management. MPD ensured constant bottomhole pressure (BHP), enhanced formation pressure monitoring, and strengthened well control. The paper highlights the benefits of early MPD integration, cost savings, and key lessons learned, including the importance of gap analysis, early adoption, and tailored training for all stakeholders.
