  • Patent number: 9033047
    Abstract: A method for enhancing hydrocarbon recovery in low permeability reservoirs comprises first providing a subterranean reservoir comprising one or more hydrocarbons and water therewithin and a wellbore in fluid communication with the subterranean reservoir. Next, a substantially anhydrous composition is injected into the reservoir through the wellbore. The substantially anhydrous composition comprises carbon dioxide and one or more surfactants. The composition is suitable to form a foam upon contact with the water within the reservoir. The method often results in reduced wellbore corrosion and hydrate formation, reduced reservoir fingering, and enhanced carbon dioxide sweep efficiency over conventional methods.

    Abstract: An apparatus and device for hydrocarbon recovery in a well for coal bed methane (CBM) recovery, tight sand gas extraction, and other gas extraction techniques provides for the formation of a hydrocarbon foam comprised of a fluid delivered into a downhole portion of the well and the hydrocarbon, maximizing water removal for gas recovery. The apparatus may include a check valve that feeds a nozzle to deliver or atomize the spray of fluid into the downhole portion of the well when the pressure applied to the fluid is sufficient to overcome a hydrostatic pressure in the downhole portion of the well and to deliver the fluid into the downhole portion of the well. The fluid is not sprayed directly into the formation, thereby protecting the formation from damage and recovering the fluid even in the case where water is not present. The capillary tube feeding the fluid to the check valve may be placed externally to the production tube to facilitate ease of cleaning and clearing of the production tube.

  • Publication number: 20120285694
    Abstract: A method for enhancing foam stability in foaming compositions for use in oilfield treatment application, including but not limited to use in mobility control for gas flooding. The method comprises the step of adding to a foaming composition a foam stabilizer of formula (I): wherein R1 is an alkylamido group or a branched or linear alkyl group; R2 and R3 are individually hydrogen or a methyl group; R4, R5 and R6 are individually hydrogen or a hydroxy group, with the proviso that at least one of R4, R5 or R6 is a hydroxyl group; wherein the alkyl group has greater than about 10 carbon atoms. Also disclosed are methods to enhance foam stability in an aqueous foaming composition.

  • Publication number: 20120279715
    Abstract: A method of foaming a fluid for recovering gas from a gas well and enhancing oil production from a gas-lifted oil well penetrating a subterranean oil-bearing formation is disclosed and claimed. The method includes introducing into the fluid a foam-forming amount of a composition comprising at least one compound having the general formula: R1 is selected from a saturated linear or branched alkyl, an unsaturated linear or branched alkyl, a substituted naphthalene, a substituted benzene, a natural oil, and a natural oil derivative. R2 is a C2-C8 alkyl. R3, R4, and R5 are independently selected from trimethyl, triethyl, diethyl, monoethyl, benzyl dimethyl, and benzyl diethyl. X is selected from hydrogen, methyl, and ethyl. Z? is a negatively charged counterion.

  • Patent number: 8302683
    Abstract: A method of increasing biogenic production of a combustible gas from a subterranean geologic formation is described. The method may include extracting formation water from the geologic formation, where the extracted formation water includes at least a first species and a second species of microorganism. The method may also include analyzing the extracted formation water to identify the first species of microorganism that promotes the biogenic production of the combustible gas. An amendment may be introduced to the formation water to promote the growth of the first species of microorganism, and the biological characteristics of the formation water may be altered to decrease a population of the second species in the geologic formation.
