20120061080 | INLINE RF HEATING FOR SAGD OPERATIONS - The present invention provides a method for accelerating start-up for SAGD-type operation by providing radio frequency heating devices inside the lateral wells that can re-heat the injected steam after losing heat energy during the initial injection. The method also extends the lateral wells such that the drilling of vertical wells can be reduced to save capital expenses. | 03-15-2012 |
20120061081 | RF FRACTURING TO IMPROVE SAGD PERFORMANCE - A method of producing heavy oil from a heavy oil formation with steam assisted gravity drainage. The method begins by drilling a borehole into a heavy oil formation comprising a steam barrier between a first pay zone and a second pay zone, wherein the steam barrier prevents a steam chamber to be formed between the first pay zone and the second pay zone. The steam barrier is then heated with a radio frequency. The steam barrier is then fractured to permit a steam chamber to be formed within the first pay zone and the second pay zone. Heavy oil is then produced from the heavy oil formation with steam assisted gravity drainage. | 03-15-2012 |
20120234537 | GRAVITY DRAINAGE STARTUP USING RF & SOLVENT - The method begins by forming a gravity drainage production well pair within a formation comprising an injection well and a production well. The pre-soaking stage begins by soaking at least one of the wellbores of the well pair with a solvent, wherein the solvent does not include water. The pre-heating stage begins by heating the soaked wellbore of the well pair to produce a vapor. The squeezing stage begins by introducing the vapor into the soaked wellbore of the well pair, and can thus overlap with the pre-heating stage. The gravity drainage production begins after the squeezing stage, once the wells are in thermal communication and the heavy oil can drain to the lower well. | 09-20-2012 |
20120273195 | METHOD FOR STEAM ASSISTED GRAVITY DRAINAGE WITH PRESSURE DIFFERENTIAL INJECTION - A process for recovering hydrocarbons with steam assisted gravity drainage (SAGD) with pressure differential injection. | 11-01-2012 |
20130199774 | HEAVY OIL PRODUCTION WITH EM PREHEAT AND GAS INJECTION - An enhanced oil recovery technique that combines gas injection with EM radiation to heat and mobilize heavy oil at least until fluid communication is achieved. | 08-08-2013 |
20140090834 | EM AND COMBUSTION STIMULATION OF HEAVY OIL - A method of producing heavy oil from a heavy oil formation by combining electromagnetic heating to achieve fluid communication between wells, following by in situ combustion to mobilize and upgrade the heavy oil. | 04-03-2014 |
