  • Publication number: 20230399561
    Abstract: A method of removing condensate banking in a subsurface formation using a treatment fluid includes injecting a treatment fluid including nanoparticles and a thermochemical component, the thermochemical component including sodium nitrite and ammonium chloride, into a wellbore having condensate banking, thereby exposing the treatment fluid to subsurface formation conditions. The method further includes allowing a temperature of the wellbore to activate the thermochemical component, causing an exothermic reaction generating nitrogen gas, pressure, and heat. The method further includes allowing the treatment fluid and generated nitrogen gas to mix with the condensate banking, thereby forming a homogenous multi-phase foam and lowering hydrostatic pressure in the wellbore. The method further includes allowing the homogenous multi-phase foam to flow back to the surface due to the pressure generated by the exothermic reaction and lowered hydrostatic pressure in the wellbore, thereby removing the condensate banking.

  • Publication number: 20230392068
    Abstract: A sand consolidation composition includes a hydrocarbon mixture comprising asphaltene, bitumen, or tar, and a binding agent, where the binding agent is an amino silane, and where the composition has a viscosity ranging from 5 to 20 cP at 20 to 25° C. A method of sand consolidation includes introducing the sand consolidation composition in a wellbore, contacting sand downhole with the sand consolidation composition, maintaining the wellbore such that a viscosity of the sand consolidation composition and the sand increases from an initial viscosity of the sand consolidation composition, introducing a thermochemical reagent comprising sodium nitrite and ammonium chloride such that it intimately intermingles downhole with the sand consolidation composition and releases a gas, and after a period, forming a productive consolidated sand.

  • Patent number: 11773316
    Abstract: A method for acidizing a subsurface formation using a treatment fluid includes injecting a treatment fluid including a strong acid, a buffer, a thermochemical component, a foaming agent and nanoparticles into the wellbore, thereby exposing the treatment fluid to subsurface formation conditions. The method further includes allowing a temperature of the wellbore to activate the thermochemical component, causing an exothermic reaction generating nitrogen gas, pressure, and heat, thereby forming fractures within the subsurface formation. The method further includes allowing the treatment fluid and nitrogen gas to mix within the subsurface formation, thereby forming a foamed acid within the fractures to acidize the subsurface formation.

  • Patent number: 11555145
    Abstract: A method for stimulating production of hydrocarbons from a sandstone formation includes the steps of injecting a stimulation fluid formed from a hydrofluoric acid generating precursor and an oxidizing agent, an ammonium containing compound, and a nitrite containing compound into the sandstone formation, where one or both of the hydrofluoric acid generating precursor and the oxidizing agent comprise a degradable encapsulation. The method further includes maintaining the stimulation fluid, the ammonium containing compound, and the nitrite containing compound in the sandstone formation to initiate reaction and generate heat and nitrogen gas. Upon generation of heat and degradation of the degradable encapsulation, the hydrofluoric acid generating precursor and the oxidizing agent react to form hydrofluoric acid in-situ to dissolve silica and silicate minerals and stimulate the sandstone formation.

  • Patent number: 11441063
    Abstract: A method for the removal of well bore damage, the method including performing an acid cleaning of one or more of a coiled tubing and the well bore using a hydrochloric acid mixture of 7 to 15 wt % hydrochloric acid and displacing the hydrochloric acid mixture with a first fresh water stream. After acid cleaning, a composition comprising at least 10 wt % acetic acid into the wellbore is injected into the wellbore. After injecting acetic acid, gel jetting of the well is performed with a gel mixture, and the gel mixture is subsequently displaced with a second fresh water stream. After gel jetting, an organic solvent mixture is injected into the well bore and allowing the organic solvent mixture to soak for 2 to 6 hours. Finally, a thermochemical mixture is injected into the well bore, thereby increasing temperature and pressure and cleaning build up from the well bore.
