ABSTRACT:
Methods for completing and producing hydrocarbon from a well having a highly permeable production formation having a water zone and a hydrocarbon zone are disclosed. In the disclosed techniques a cased well borehole is cemented in place through the production formation. A packer is set in the casing to isolate the hydrocarbon zone from the water zone. Perforations in the water zone and in the hydrocarbon zone produce a mixture of both fluids into the casing/tubing annulus at different bottom hole pressures (FBHP's) due to the installation of a flow restriction limiting the flow of either hydrocarbon or water into the tubing string. Artificial lift means are used to produce the fluid mixture to the surface.
