Automated Managed-Pressure Drilling Helps Find Reserves Near Failed Exploration Well

Wilson, Adam (JPT Editorial Manager)


The SB field is considered a very challenging area because the pressure and temperature in the depositional environment are abnormally higher than in neighboring fields. Some of the key challenges with this high-pressure/hightemperature (HP/HT) environment are reduced kick tolerance, narrow drilling window between pore pressure and fracture gradient, higher drillingfluid densities, temperature limitation on formation-evaluation bottomholeassembly components that limits data acquisition, wellbore ballooning and breathing, and number of personnel with HP/HT drilling experience.
