  • Patent number: 10753188
    Abstract: A method for thermal recovery of hydrocarbon housed in a reservoir comprising injecting a mixture comprising either hydrocarbon and water (for downhole heating) or hydrocarbon and steam (heated at surface) into a wellbore and circulating the heated mixture of hydrocarbon and steam inside the wellbore allowing the heated mixture to increase the temperature of the reservoir and thereby reduce the viscosity of the hydrocarbon within the reservoir. The injection of steam facilitates the delivery of more heat to the reservoir due to the latent heat of steam, compared with circulating heated hydrocarbon alone.

    Abstract: Heavy oil recovery using downhole radio frequency radiation heating accelerates SAGD thermal recovery processes. In one embodiment, one or more SAGD well pairs traverse a subterranean formation for recovering heavy oil. The SAGD well pairs each create a steam chamber which, over time, expands to allow each steam chamber to interact with one another and in this way, increases the recovery heavy oil from the formation. One or more antennas may be interposed between the steam chambers to introduce electromagnetic radiation into the formation to heat the fluids therein to accelerate expansion of the steam chambers, particularly where antennas are judiciously situated to optimize steam chamber expansion. Where an infill production well is present, the antennas may be situated to accelerate steam chamber communication with the infill production well. Advantages include lower cost, higher efficiencies, quicker and increased hydrocarbon recovery.

    Abstract: Method for preheating an oil reservoir comprises injecting saturated or superheated steam at an initial injection pressure into a tubing placed inside a well drilled in the oil reservoir. Steam temperature at an outlet of the tubing is measured and a heat flow from the well to the oil reservoir is calculated. An optimal steam injection rate when steam quality of the injected steam at the tubing outlet becomes greater than zero, is calculated, the optimal steam injection rate ensuring compensation of the heat flow from the well to the oil reservoir with the heat of steam condensation. A steam injection rate is decreased to the calculated optimal steam injection rate value by decreasing the initial injection pressure providing constant temperature at the outlet of the tubing.

  • Patent number: 9353611
    Abstract: Superheated steam from a generator (10) proximate a well (14) is delivered through an output pipe (12) that communicates through a dual entry wellhead (17) with downhole steam piping (18) extending into the well (14). Steam is delivered at approximately 50 PSIG over the frictional and other losses encountered from the surface to the steam piping outlet (19). Oil is extracted through production tubing (20) passing through wellhead (17). Production tubing (20) and steam delivery piping (18) are secured in parallel relationship by clamps (46). The production tubing (20) communicates with a lift pump, and the steam piping (18) is terminated generally at a midpoint of the production tubing (20), several feet above the lift pump. A thermocouple (43) is placed approximately two feet below the end of the steam piping (18).

  • Patent number: 9334720
    Abstract: Fracturing slurries are prepared on the fly using a solids pump to feed the solid such as a gel into a liquid stream of normally water for pumping downhole with a large capacity triplex pump. The solids pump is preferably a Posimetric® style which delivers the solid into the fluid pipeline in a manner that keeps fluid from backing into the solids hopper above the solids pump. A separate fluid tank is connected to a fluid pump to pressurize a suction line to a boost pump before reaching the triplex pump and pumping into the subterranean formation. The solids pump can deliver between the fluid and boost pumps in which case the solids go through the triplex pump or alternatively the solids can be delivered into the higher pressure discharge line of the triplex pump.

  • Patent number: 9238957
    Abstract: A downhole injection apparatus having a sleeve disposed in a tubular housing. The sleeve and housing define an annular orifice through which steam flows prior to injection into the wellbore. Water condensate collects at the orifice or restriction proximate the orifice and is mixed with or entrained into the flow of steam. The sleeve preferably has a plurality of generally radial ports such that steam flows from interior the sleeve to the annulus. Preferably the injection ports and sleeve ports are angled to reduce or eliminate radical changes in direction of the steam flow.

  • Patent number: 9127542
    Abstract: A process of treating a subterranean well comprising a plurality of flow channels and at least one of the flow channels is impaired. The treatment is used for alleviating the impairment. The process comprises a flow of gaseous carrier fluid supplied into the subterranean well. The gaseous carrier fluid pushes liquids out of the plurality of the flow channels. A liquid treatment agent is created. To create the liquid treatment agent, first, a surfactant solution is created and diluted with a solvent. The surfactant solution is created by compounding a plurality of non-ionic ethoxylated sorbitan fatty acid ester surfactants together until a proper hydrophilic-lipophilic balance is achieved. At some point, the liquid treatment agent is atomized. This atomized liquid treatment agent is blended with the gaseous carrier fluid, to create an atomized treatment fog. The atomized treatment fog is supplied into the subterranean well.
