Abstract
A method of constructing a packer assembly can include installing a body lock ring on a mandrel, and then outwardly surrounding the body lock ring with a structure displaceable relative to the mandrel by a setting mechanism. A packer assembly can include a setting mechanism which displaces a structure relative to a mandrel, and a mandrel lock device which permits one way displacement of the structure relative to the mandrel, the mandrel lock device including a body lock ring and a bias sleeve which urges the body lock ring into gripping engagement with the mandrel, the bias sleeve and the structure being separate elements of the packer assembly. The bias sleeve can be secured against rotation relative to the mandrel while the structure is rotatable relative to the mandrel.
