These advantages ultimately translate to higher production and/or reduction of total hydrocarbon extraction time. These methods are particularly advantageous when applied to shallow reservoirs (e.g. reservoirs having depths less than or equal to about 150 meters). | 07-05-2012 |
20120247760 | DUAL INJECTION POINTS IN SAGD - A method for recovering petroleum from a formation, wherein at least two injection wells and at least one production well are in fluid communication with said formation, comprising: introducing a gaseous mixture into a first and a second injection well at a temperature and a pressure, wherein said gaseous mixture comprises steam and non-condensable gas (NCG); and recovering a fluid comprising petroleum from said production well, wherein said injection wells and a production well are horizontal wells, and wherein said first injection well is disposed 1-10 meters above said production well, and said second injection well is disposed at least 5 meters above said first injection well. | 10-04-2012 |
20120312534 | ENHANCED HYDROCARBON RECOVERY THROUGH GAS PRODUCTION CONTROL FOR NONCONDENSABLE SOLVENTS OR GASES IN SAGD OR ES-SAGD OPERATIONS - Methods are provided for enhancing hydrocarbon recovery through gas production control for noncondensable gases in SAGD or ES-SAGD operations. Steam may be injected into one or more injection wells to heat the hydrocarbons and reduce their viscosity to more easily produce the hydrocarbons. A noncondensable gas may be injected into the injection wells to beneficially reduce the steam-to-oil ratio, improving economic recovery. Unfortunately, excessive production of noncondensable gases can adversely suppress hydrocarbon production rates. To counteract this problem, gas production rates at the production wells may be controlled to optimize hydrocarbon output by limiting the produced gas-to-water ratio to certain limited ranges. The noncondensable gas may optionally comprise a combustion gas such as flue gas. By providing a useful application of existing combustion gases, green house gases emissions may be reduced. Advantages include higher efficiencies, lower costs, reduced hydrocarbon extraction time, and in some embodiments, reduced greenhouse gas emissions. | 12-13-2012 |
20140144627 | HYDROCARBON RECOVERY WITH STEAM AND SOLVENT STAGES - A steam-assisted gravity drainage method includes a two stage solvent injection scheme, wherein steam plus solvent injection is followed by steam plus heavier-solvent injection. The two solvent injections improve recoveries of both the heavy oil and the injected solvent while limiting steam requirements, thus improving the economics of the method. | 05-29-2014 |
20140332210 | TOP-DOWN OIL RECOVERY - Methods relate to producing hydrocarbons, such as bitumen in an oil sands reservoir. The methods include utilizing an injector well with multiple horizontal laterals to provide downward fluid drive toward a producer well. Combined influence of gravity and a dispersed area of the fluid drive due to the laterals facilitate a desired full sweep of the reservoir. Fluids utilized for injection include water heated to less than 60 weight percent steam, solvent for the hydrocarbons and emulsifying agent for the hydrocarbons. The methods employing these fluids provide energy efficient recovery of the hydrocarbons. | 11-13-2014 |
