Abstract
A wellbore system includes a sealing assembly for creating an annular seal between wellbore members. The sealing assembly includes a seal body having a u-shaped cross section, with elongate grooves formed on inner and outer walls thereof. A depth of the grooves varies along a length of the grooves to allow wickers to penetrate the groove by differing degrees when the walls are urged toward the wickers. The wickers can thus provide a high degree of both sealing and lockdown performance.
