MANAGED PRESSURE DRILLING: (JUST) A DRILLING PERFORMANCE TOOL OR A KEY SAFETY ENHANCER?

Open publisher page 0 citations

Abstract

Managed Pressure Drilling (MPD) is broadly defined as an adaptive drilling process used to control the annular pressure profile throughout the wellbore. This technology was originally developed to increase the boundaries of drilling operations, allowing to walk the narrow gap between pore and fracture pressure gradients in deep formations, perhaps not drillable with conventional operations. It is well recognized that MPD helps reduce non productive time in critical wells but this Workshop will explore another critical perspective: how the use of MPD can improve HSE during drilling operations.
