This paper presents developments in the management of drilling fluids for use in high-pressure, high-temperature (HPHT) wells, especially a process that includes both a methodology for the management of bottom hole mud pressure and the use of modeling software that enables it, The developments have contributed to the success of four HPHT wells in the UKCS Central Graben. This paper discusses three essential elements for successful fluid engineering during HPHT drilling operations.
