Method and means for stabilizing gravel packs
This patent describes a fluid production or injection well comprising a well bore penetrating a subterranean producing zone, gravel pack liner tubing in the well bore having apertures therein, a gravel pack in the annulus between the liner tubing and the well bore, a tubing string connected to the liner tubing through which produced fluid can flow, and a packer surrounding the tubing string at a location spaced above the gravel pack. This paper describes improvement in pressure relief valve means; the pressure relief valve means comprising a check valve located radially outwardly of the inside diameter of the tubing string; and the check valve including a screen covered outlet opening to the check valve for preventing entry of particulate matter larger than the screen size into the check valve while the check valve is open.
