WELL WITH SAND CONTROL AND STIMULANT DEFLECTOR (D#77,400-TCRL-003-F) ABSTRACT OF THE DISCLOSURE A well completion and method for improving the productivity of hydrocarbon emulsion from a substrate layer which holds the hydrocarbon. The well completion includes an elongated substantially horizontally disposed liner, the walls of which are perforated to receive the emulsion from the substrate. Operationally, a flow of hot stimulating fluid is injected into the productive layer in a manner to achieve optimum penetration, as well as maximum horizontal sweep thereof. A flowable dam or gravel pack is disposed at the completion remote end and serves to pass a flow of stimulating fluid whereby to achieve the desirable distribution of said stimulating medium into the substrate. However, the gravel pack deters passage of emulsion back into the liner.
