摘要:
A composition, treatment fluid and method using hydrolyzable fines. A treatment fluid, which may optionally include a high solids content fluid (HSCF) and/or an Apollonianistic solids mixture, includes a fluid loss control agent comprising a dispersion of hydrolyzable fines, optionally with one or more of a surfactant, plasticizer, dispersant, degradable particles, reactive particles and/or submicron particles selected from silicates, γ-alumina, MgO, γ-Fe2O3, TiO2, and combinations thereof.

A method of placing proppant into a fracture formed in a subterranean formation from a wellbore is disclosed. The method comprises injecting through the wellbore a first treatment fluid to initiate the fracture in the subterranean formation; injecting through the wellbore a second treatment fluid comprising a particulate blend slurry made of proppant; the particulate blend comprising at least a first amount of particulates having a first average particle size between about 100 and 5000 μm and at least a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size; and forming with the particulate blend slurry a plurality of proppant-rich clusters spaced apart by proppant-free regions forming open channels.

A method of treating a subterranean formation of a well bore comprises providing a treatment fluid comprising a carrier fluid, a particulate material, a viscosifying agent and fumed silica, wherein fumed silica is in such concentration to reduce the settling rate of the particulate material in the treatment fluid; and introducing the treatment fluid into the wellbore.

摘要:
Methods which include hydrating a crystalline polymeric material in a first liquid medium, precipitating the polymeric material to form an amorphous polymeric material, and combining amorphous polymeric material with a second liquid medium to form a treatment fluid. Alternative methods include hydrating a crystalline polymeric material in a first liquid medium, precipitating the polymeric material to form a lower crystalline form of the polymeric material, and combining the lower crystalline form of polymeric material with a second liquid medium to form a treatment fluid.
摘要:
A method of treating a subterranean formation penetrated by a wellbore involves introducing an acid treatment fluid through the wellbore into the formation. The treatment fluid is formed from a zwitterionic viscoelastic surfactant, an acid in an amount to provide the treatment fluid with an initial pH of ≦0 and a rheology enhancer. The treatment fluid has a high viscosity at the initial pH and a lower viscosity when the pH of the treatment fluid is raised to an intermediate pH of from greater than 0 to about 5.
