    摘要: An oil production system and method. The system includes a system for heating unrecovered oil. The system includes a chemical injection well having at least one subterranean outlet. The system also includes an oil production well with at least one subterranean inlet. The subterranean outlet is lower in elevation than the at least one inlet. The chemical injection well is coupled to an injected reactant source, and wherein said injected reactant source reacts with a second reactant in an exothermic reaction.

    摘要: Some methods of production hydrocarbons from a formation comprise drilling two or more horizontal wellbores in the formation, at least a portion of each extending in a direction that is within 20 degrees of parallel to a direction of maximum horizontal stress of the formation. The horizontal wellbores can include one or more producer wellbores and one or more injector wellbores, each of the producer wellbore(s) separated from at least one of the injector wellbore(s) by a formation-permeability-dependent well spacing. Some comprise comprising creating one or more longitudinal fractures that are in communication with the formation in each of the horizontal wellbores, injecting a recovery fluid comprising gas into at least one of the injector wellbore(s) such that the recovery fluid flows into the formation, and receiving hydrocarbons from the formation into at least one of the producer wellbore(s).

    摘要: Various examples are provided related to airlift pumping of downhole geothermal fluids. In one example, an airlift system includes a compressor; a gas sparger head in a wellbore of a geothermal well, and a pressure head recycle assembly. The sparger head produces artificial lift of the geothermal fluids by injecting a gas resulting in a difference in density downhole. The entrained gas can be extracted by the pressure head recycle assembly, compressed, and reinjected downhole. The geothermal fluid at the well head can be used in direct use applications or in a thermodynamic cycle to make shaft power. The gas sparger head can include a venturi shaped passage extending through the gas sparger head and a bubble orifice including gas orifices radially spaced about a narrow portion of the venturi shaped passage. The gas orifices can have a corresponding resonant chamber through which the gas (e.g., air) is provided.

    摘要: A novel tool for improving the efficiency of extraction of hydrocarbons from underground formations is described. The tool is configured to produce localized waves of high pressure fluid at a location within a wellbore. These pressure waves are effective to displace hydrocarbons within a geological formation such that enter the interior of the wellbore where they can be more easily removed by means of an accompanying pump assembly.
