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.

Method and composition for acidizing a subsurface formation utilizing a nitrogen gas-generating treatment fluid

A composition includes a nonionic fluorinated polymeric surfactant, a nonfluorinated surfactant, and a scale treatment. Additionally, a method for scale treatment is provided. The method includes injecting gas into the aforementioned composition to produce a foam and injecting the foam into a formation. In the formation, the foam may be exposed to a first temperature at which it has a first viscosity. The foam may be maintained inside the formation for a period of time, and then recovered from the formation, at which point it is exposed to a second temperature and has a second viscosity.
