In an embodiment, the present disclosure relates generally to a method for well stimulation. In some embodiments, the method includes pumping a treatment fluid into a well. In some embodiments, the treatment fluid includes carbon dioxide (CO.sub.2) and a breaker, and the method further includes treating at least one of a reservoir and a wellbore of the well with the treatment fluid. In some embodiments, the breaker is a solution of stabilized chlorine dioxide (ClO.sub.2). In some embodiments, the method further includes commingling the CO.sub.2 with water and forming, as a result of the commingling, carbonic acid. In some embodiments, the method includes activating the stabilized ClO.sub.2 to form activated ClO.sub.2. In some embodiments, the activated ClO.sub.2 is formed as a result of a lowering of pH in the treatment fluid by the carbonic acid.

A composition of a treatment fluid having an aqueous base fluid and a true crystallization temperature reduction additive. A method includes providing a treatment fluid having an aqueous base fluid, adding a true crystallization temperature reduction additive and placing the treatment fluid in a subterranean wellbore.

The use of a quaternary ammonium salt of a polyalkoxylated amine as a stabilisation additive in an oilfield fluid comprising water.

Methods comprising preparing a gelled fluid comprising a base fluid, a first gelling agent, and particulates; introducing the gelled fluid into a process stream, the process stream in fluid communication with a subterranean formation; introducing anhydrous ammonia into the gelled fluid at a downstream location in the process stream, thereby forming a particulate-containing treatment fluid; and introducing the particulate-containing treatment fluid into the subterranean formation from the process stream and through the wellhead.

Reaction products produced by mixing a maleated tall oil fatty acid and/or a maleated soy oil fatty acid/DETA component with an amine or amine bottom preparation are used as clay inhibitors in drilling fluids and in hydraulic fracturing fluids for drilling wells and for fracturing subterranean formations, and are also used as clay inhibitors in other treatment fluids for treating wells or subterranean formations.

Various embodiments disclosed relate to guanidine- or guanidinium-containing clay or shale stabilizers for treatment of subterranean formations. In various embodiments, the present invention provides a method of treating a subterranean formation that can include placing a composition including a clay or shale stabilizer including at least one of a substituted guanidine group and a substituted guanidinium group in a subterranean formation.

The present technology relates to a process for enhancing hydrocarbon production from a shale formation. In particular, the present technology relates to a process wherein a treatment fluid comprising a water soluble delayed release carbonate-dissolving agent is introduced into the shale formation after or as part of a hydraulic fracturing process. The present technology also relates to a treatment fluid that can be used in such a process.

Clay stabilization compositions include one or a plurality of triamino compounds and/or derivatives thereof, fluids containing an effective amount of the clay stabilization compositions and methods for making and using same.

Various embodiments disclosed relate to guanidine- or guanidinium-containing clay or shale stabilizers for treatment of subterranean formations, in various embodiments, the present invention provides a method of treating a subterranean formation that can include placing a composition including a clay or shale stabilizer including at least one of a substituted guanidine group and a substituted guanidinium group in a subterranean formation.

A process comprising spraying production saltwater comprising water and dissolved salt through an evaporator to evaporate a portion of the water, collecting unevaporated saltwater which is an unevaporated portion of the saltwater that remains after being sprayed through the evaporator, and adjusting a salinity of at least a portion of the unevaporated saltwater to yield an adjusted brine product.
