Critical requirements for successful fluid endineering in HPHT wells: modeling tools, design procedures bottom hole pressure management in the field

摘要

THis paper presents deveopments 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 s uccessful fludi enineering during HPHT drilling operations: an accurate hydraulics program couple with a temperature simulator procedures for design and planning bottom-hole pressure management in the field
