Annular Pressure Buildup (APB) occurs in all wells with high bottom hole temperature, multiple casing strings and annuli that cannot be vented--which includes most deepwater Gulf of Mexico wells. APB can result in casing string and premature well failure, unless a well is properly designed. APB risks are fully assessed for all load cases, and any necesary APB mitigation methods are evaluated, fully analyzed for effectiveness, and properly implemented.

This project covers RPSEA RFP requirements of analyzing APB mitigation technologies. Moreover, will provide industry with a stochastic tool for analysis, comparison, and choice of possible APB mitigation techniques applicable to an operator's well and field situation.
