Summary:
In deepwater exploration wells uncertainty in pore pressure (PP) and fracture gradient (FG) and the margin between them increases the potential risk of gas influx, lost circulation, and wellbore instability. The risk of total losses is even greater in deepwater exploration prospects that contain salt and fractured carbonates. A new managed pressure drilling (MPD) system has been used in Guyana to drill deepwater exploration wells that have many of the same problems and potential risks that will occur in Mexico.
