| 20080196892 | Enzyme enhanced oil recovery (EEOR) for waterflooding operations - The present disclosure involves the release or recovery of subterranean hydrocarbon deposits and, more specifically, to a system and method for secondary and/or enhanced oil recovery (EOR), by utilizing waterflooding compositions that include enzymes as well as methods for injecting waterflooding compositions into subterranean formations for oil recovery operations. | 08-21-2008 |
| 20090050325 | Enzyme enhanced oil recovery (EEOR) for near wellboretreatment of oil and gas with greater than 50% barrel of oil equivalent (BOE) gas production - Disclosed is a system for injecting an enzymatic fluid composition into a gas or gas and oil near-well bore having a wide temperature range. The enzymatic fluid composition is a treatment for reducing oil deposits, asphaltenes, waxes, scale, or other hydrocarbon materials in a gas well or a combination gas/oil well where the production of gas is greater than 50% on a barrel of oil equivalent (BOE) basis. | 02-26-2009 |
| 20090062153 | Enzyme enhanced oil/gas recovery (EEOR/EEGR) using non-gel hydraulic fracturing in hydrocarbon producing wells - The present application describes enhanced recovery of oil and/or other hydrocarbons in a subterranean formation such that oil and/or hydrocarbons are released by a hydraulic fracturing process with a non-gel hydraulic fracturing fluid that comprises an oleophilic enzyme thereby forming a non-gel hydraulic fracturing fluid enzyme composition which is injected during an initial or later stage. | 03-05-2009 |
| 20090260827 | Enzyme enhanced oil recovery (EEOR) for water alternating gas (WAG) systems - The present disclosure relates to the release or recovery of subterranean hydrocarbon deposits and, more specifically, to a system and method for enhanced oil recovery (EOR), by utilizing enzyme compositions and water-alternating-gas (WAG) methods for injecting water compositions, followed by miscible, near miscible or immiscible gas into subterranean formations for oil recovery operations. | 10-22-2009 |
| 20090266547 | Enzyme enhanced oil recovery (EEOR) for near wellbore treatment of oil and gas with greater than 50% barrel of oil equivalent (BOE) gas production - Disclosed is a system for injecting an enzymatic fluid composition into a gas or gas and oil near-well bore having a wide temperature range. The enzymatic fluid composition is a treatment for reducing oil deposits, asphaltenes, waxes, scale, or other hydrocarbon materials in a gas well or a combination gas/oil well where the production of gas is greater than 50% on a barrel of oil equivalent (BOE) basis. | 10-29-2009 |
| 20090288826 | Enzyme enhanced oil recovery (EEOR) for cyclic steam injection - The present disclosure relates to the release or recovery of subterranean hydrocarbon deposits and, more specifically, to a system for enhanced oil recovery (EOR), by utilizing stabilized enzymatic fluid and cyclic injection of steam or heated fluid into subterranean formations. | 11-26-2009 |
| 20090288843 | Enzyme enhanced oil recovery (EEOR) for waterflooding operations - The present disclosure involves the release or recovery of subterranean hydrocarbon deposits and, more specifically, to a system and method for secondary and/or enhanced oil recovery (EOR), by utilizing waterflooding compositions that include enzymes as well as methods for injecting waterflooding compositions into subterranean formations for oil recovery operations. | 11-26-2009 |
| 20100300693 | Enzyme Surfactant Fluids Used in Non-Gel Hydraulic Fracturing of Oil Wells - The present application describes improved total recovery of oil, condensate and associated gas in a subterranean formation such that said hydrocarbons are released by a hydraulic fracturing process with a non-gel hydraulic fracturing fluid that comprises an enzyme surfactant fluid with at least one anionic surfactant thereby forming a non-gel hydraulic fracturing fluid enzyme surfactant composition which is injected at 1 to 3 percent of total frac fluid during fracturing. | 12-02-2010 |
