Claim 1
Independent Claim
146 words
A METHOD OF COMPLETING AND PRODUCING A WELL THAT PENETRATES AN UNCONSOLIDATED OIL-BEARING SUBTERRANEAN FORMATION WHEREIN THE OIL INCLUDES BOTH VOLATILE AND RESIDUAL HYDROCARBONS WHICH COMPRISES INJECTING AN OILDISPLACING FLUID INTO THE FORMATION FROM THE WELL AT A PRESSURE IN EXCESS OF FORMATION PRESSURE AND IN A QUANTITY SUFFICIENT TO DISPLACE A PART OF THE OIL FROM THE PORTION OF THE FORMATION THAT IMMEDIATELY SURROUNDS THE WELL BORE AND TO MOVE THE DISPLACED OIL DEEPER INTO THE FORMATION, HEATING SAID PORTION OF SAID FORMATION TO A TEMPERATURE IN THE RANGE FROM ABOUT 400*F. TO ABOUT 1300* F. WHICH IS SUFFICIENT TO VAPORIZE VOLATILE HYDROCARBONS AND TO BOND RESIDUAL HYDROCARBONS TO THE PARTICLES OF SAID UNCONSOLIDATED FORMATION, THEREAFTER TERMINATING SAID HEATING, AND REDUCING THE PRESSURE WITHIN THE WELL TO A VALUE LESS THAN FORMATION PRESSURE SO THAT OIL MAY THEREBY FLOW FROM THE FORMATION INTO THE WELL.
