ABSTRACT:
It has been discovered that the production or recovery of oil or bitumen produced or recovered in the form of an oil-in-water emulsion form a porous water containing oil or bitumen producing formation is maintained and improved by maintaining the temperature of the produced oil or bitumen in the form of an oil-in-water emulsion at a temperature not lower than and preferably greater than Tc, wherein Tc is the minimum temperature for the oil or bitumen, such as in the form of an oil-in-water emulsion, to flow through the porous water-containing oil or bitumen producing formation. In a special practice of this invention to prevent water coning, a substantially water impermeable barrier can be produced in a water saturated formation by depositing therein a bitumen or oil-in-water emulsion barrier or zone at a temperature below Tc.
