... of bottomhole pressure (BHP) increase is accompanied by a change in the dynamic head and increasing the gas pressure at annular space ( Shagiev, 1998 ). Growth of casing pressure above limit pressure can lead to technical problems at wellhead. This paper describes a method for predict the pressure...

...P. Oudeman; L. J. Bacarreza The problem of annular pressure buildup due to heating of the strings by the (hot) well effluent, will typically be of concern in the design of casing strings for high-pressure/high-temperature (HP/HT) sub-sea wells. In such completions bleeding off the pressure through...
