Abstract
The present invention generally relates to apparatus and methods for completing a well. Particularly, the present invention relates to a single-direction plug for use with cementing applications and with drilling with casing applications. One embodiment comprises a cement plug for installation in a wellbore casing. The plug includes a body and gripping members for preventing movement of the body in a first axial direction relative to the casing. The plug further comprises a sealing member for sealing a fluid path between the body and the casing. The plug is movable in a second axial direction with fluid pressure but is not movable in the first direction due to fluid pressure.
