Abstract
A gravel pack apparatus and associated method of completing subterranean wells provides convenient and economical gravel packing operations, permitting a sand control screen to be run into the well attached to the apparatus which is, in turn, attached to production tubing, and further permitting the tubing to be detached from the screen. In a preferred embodiment, a gravel pack apparatus has interoperable valve and tubing release portions. The valve portion may be closed after the gravel packing operation is completed. Closure of the valve portion activates the release portion, permitting the apparatus to be separated.
