ABSTRACT:
Process for producing bitumen from a subterranean reservoir of tar sands comprises heating the casing for melting the bitumen from the tar sands adjacent the casing for forming a passage in the reservoir from upper perforations at the top of the reservoir to lower perforations at the bottom of the reservoir, setting a packer in an annulus between the casing and a tubing therein between the upper and lower perforations, circulating hot fluids from the upper perforations and back into lower perforations for melting more bitumen from the tar sands for forming a predetermined size cavity around the casing, adding a packer and a screen to the tubing, ejecting a gravel pack material slurry into the cavity around the screen, ejecting more hot fluids into the cavity for melting more bitumen from the tar sands, and flowing the melted bitumen through the gravel pack, lower perforations, and screen for filtering out the sand and gravel from the melted bitumen for recovering the melted bitumen at the surface. A modification of the above process is disclosed.
Two new methods for forming a gravel pack in a subterranean reservoir of tar sands are disclosed.
