20140360727 | REMEDIATION OF ASPHALTENE-INDUCED PLUGGING OF AN OIL-BEARING FORMATION - A system and method for remediation of asphaltene-induced fouling of an oil-bearing formation is provided wherein an asphaltene solvent comprising at least 75 mol % dimethyl sulfide is introduced into an oil-bearing formation containing asphaltene deposits and the dimethyl sulfide is contacted with the asphaltene deposits. | 12-11-2014 |
20140367097 | OIL RECOVERY SYSTEM AND METHOD - A system and process are provided for recovering oil from an oil-bearing formation. An oil recovery formulation that is first contact miscible with a liquid petroleum composition that is comprised of at least 15 mol % dimethyl sulfide is introduced together with steam or hot water into a subterranean oil-bearing formation comprising heavy oil, extra heavy oil, or bitumen, and oil is produced from the formation. | 12-18-2014 |
