20140166279 | EXTENDED REACH STEAM ASSISTED GRAVITY DRAINAGE WITH OXYGEN ("ERSAGDOX") - A process to recover hydrocarbons from a reservoir, where the hydrocarbons have an initial viscosity greater than 100,000 cp, preferably greater than 1,000 cp, the process including:
| 06-19-2014 |
20140166278 | USE OF STEAM-ASSISTED GRAVITY DRAINAGE WITH OXYGEN ("SAGDOX") IN THE RECOVERY OF BITUMEN IN LEAN ZONES ("LZ-SAGDOX") - A process to recover hydrocarbons from a reservoir having at least one lean zone, wherein said lean zone has an initial bitumen saturation level less than about 0.6, said process including:
| 06-19-2014 |
20140144623 | METHOD FOR INCREASING PRODUCT RECOVERY IN FRACTURES PROXIMATE FRACTURE TREATED WELLBORES - A method of recovering product from a fracture below a surface, said method including:
| 05-29-2014 |
20140138287 | INTEGRATED CENTRAL PROCESSING FACILITY (CPF) IN OIL FIELD UPGRADING (OFU) - A process for upgrading oil including optionally pre-treating a heavy oil including at least one dissolved gas, asphaltenes, water, and mineral solids; reducing at least one dissolved gas content from said heavy oil, optionally further reducing water content from said heavy oil; adding a paraffinic solvent to said heavy oil, at a predetermined paraffinic solvent:heavy oil ratio, facilitating separation of asphaltenes, water, and mineral solids from the heavy oil resulting in a de-asphalted or partially de-asphalted oil (“DAO”)-paraffinic solvent stream, comprising a low asphaltenes content DAO-paraffinic solvent stream and an asphaltenes-mineral solids-paraffinic solvent-water slurry stream; optionally separating the paraffinic solvent and water from the asphaltenes-mineral solids-paraffinic solvent-water slurry stream; optionally separating the DAO-paraffinic solvent stream into a paraffinic solvent rich stream and a DAO stream; and optionally adding diluent to the DAO stream resulting in transportable oil. | 05-22-2014 |
20140096962 | STEAM ASSISTED GRAVITY DRAINAGE WITH ADDED OXYGEN ("SAGDOX") IN DEEP RESERVOIRS - A process to recover hydrocarbons, from a hydrocarbon reservoir having a bottom, using a substantially horizontal production well, the substantially horizontal production well having a toe and a heel, the process including:
| 04-10-2014 |
20140096960 | USE OF STEAM ASSISTED GRAVITY DRAINAGE WITH OXYGEN ("SAGDOX") IN THE RECOVERY OF BITUMEN IN THIN PAY ZONES - A SAGDOX process to recover liquid hydrocarbons from at least one thin pay zone in a hydrocarbon bitumen reservoir, via a substantially horizontal production well, where the hydrocarbon bitumen reservoir has a top and a bottom. The process includes:
| 04-10-2014 |
20140076555 | METHOD AND SYSTEM OF OPTIMIZED STEAM-ASSISTED GRAVITY DRAINAGE WITH OXYGEN ("SAGDOXO") FOR OIL RECOVERY - A steam assisted gravity drainage with injected oxygen (SAGDOX) process to recover hydrocarbons in a hydrocarbon reservoir including:
| 03-20-2014 |
