A series of numerical evaluations were undertaken to establish the relationship between casing curvature and the leakage potential/rates of different premium connections under cyclic steam injection conditions. The connection evaluations were conducted by finite element analyses, with the loading conditions for the analyses derived from another study completed previously by C-FER, which investigated the presence and magnitude of casing curvature occurring in typical thermal wells. The results quantified the connection seal performance as a function of connection geometry, connection material properties, temperature, internal pressure, curvature loading, and load path of the shear displacement.
