An assembly and a method for sealing a tubular in a wellbore, where the wellbore sealing assembly includes a hollow housing body and a seal. The hollow housing body is configured to receive a tubular. The seal is positioned within the hollow housing body and has a first movable end and a second movable end. A first seal surface and a first hollow housing inner surface define a first hollow housing cavity. A second seal surface and a second hollow housing surface define a second hollow housing cavity. The seal is configured to seal fluid in the first hollow housing cavity from fluid in the second hollow housing cavity when the tubular is disposed in the hollow housing body. The first movable end and the second movable end are moveable to change a length of a third seal surface shared between the seal and the tubular.
