  • Patent number: 11326090
    Abstract: A well cleanup process involves removing an impermeable filter cake from a formation face with thermochemical and chelating agents to allow formation fluids to flow from a reservoir to a wellbore. The method may be used with oil and water-based drilling fluids with varied weighting agents, e.g., bentonite, calcium carbonate, or barite. Such thermochemical agents may involve two salts, e.g., NO2? and NH4+, which, when mixed together, can generate pressure and heat, in addition to hot H2O and/or N2. For example, the thermochemical agents may comprise Na+, K+, Li+, Cs+, Mg2+, Ca2+, and/or Ba2+ with NO2? and NH4+ with F?, Cl?, Br?, I?, CO32?, NO3?, ClO4?, and/or ?OH.

  • Patent number: 10472560
    Abstract: Fracturing (or fracking fluids) used to enhance hydrocarbon extraction for subterranean rock formations may impede the recovery of the targeted hydrocarbons. Thus, it is common practice to inject a breaker into the subterranean rock formation to reduce the viscosity of the fracking fluids. The chemicals used to reduce the viscosity, called breakers, need to act after the tracking fluids have opened the pores in the subterranean rock formations, but before hydrocarbon extraction is hindered. A novel method for controlling the release of the breakers is disclosed. This method comprises encapsulating the breakers within a capsule comprised of water-soluble polymers and water-insoluble polymers. The water-soluble polymers are dissolved controllably by fluids within the well, allowing the breakers to react with the fracking fluids.

  • Patent number: 10400566
    Abstract: A method of increasing a permeability of a strata includes positioning an electromagnetic tool at a first location of the strata, generating a first time-varying magnetic field using the electromagnetic tool, and applying a first time-varying magnetic force to a first magnetic material of the strata using the first time-varying magnetic field, where the strata includes a first plurality of pores. The method further includes fracturing the strata to increase the permeability of the strata proximate the first location using the first time-varying magnetic force.

  • Patent number: 10358594
    Abstract: The present disclosure relates to a crosslinking composition for use in crosslinking an aqueous suspension of guar, for use as a well treatment fluid and/or proppant carrier fluid for natural gas extraction. The present crosslinking composition is an aqueous suspension of hydroboracite. The composition may also comprise varying amounts of borax, canola oil, xanthan, glycerol, and/or NaOH. The composition may be selected to effect a desired delay in the crosslinking reaction in order to customize the viscosity and reaction time to the method of use, thereby maximizing proppant delivery while minimizing pump pressure.

  • Patent number: 10323174
    Abstract: The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g., in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.

  • Patent number: 10308862
    Abstract: A cleanup fluid for reducing a viscosity of a residual viscous material in fractures of a hydrocarbon-bearing formation. The cleanup fluid includes an exothermic reaction component operable to generate heat, where the heat is operable to reduce a viscosity of the residual viscous material to create a reduced viscosity material, the reduced viscosity material operable to flow from the fractures.

  • Patent number: 10308860
    Abstract: Compositions for removing filter cake from a subterranean borehole and methods for degrading filter cake and filter cake removal are provided. The composition contains an encapsulated peroxygen (e.g., acrylic resin coated ammonium persulfate), a surfactant (e.g., nonionic surfactant), and optionally an unencapsulated peroxygen. The method (e.g., a one-step method) involves contacting the filter cake with the composition, and allowing the composition to remain in contact with the filter cake for a period of time sufficient to degrade the filter cake. The reaction of the composition with the filter cake results in acidic conditions, thereby eliminating any need for follow up acid treatments. The composition is stable enough to effectively remove filter cake at temperatures up to 250° F. or greater. Through filter cake removal, the method provides for increased flow, production, and/or recovery of oil and gas hydrocarbons from a subterranean formation.
