Methods can include contacting an aqueous fluid including a zirconium salt with a scale inhibitor in a subterranean formation to form a zirconium salt/scale inhibitor complex, and systems related thereto.

Use of zirconium salts as scale inhibitor squeeze enhancers

A method may include providing a treatment fluid comprising a metal sulfide dissolver and a base fluid. The metal sulfide dissolver includes a chelating agent, a boosting agent, a scaling agent, and a dispersing agent. The treatment fluid is then injected to contact a metal sulfide scale, which dissolves at least partially. The treatment fluid may be injected into a wellbore as a standalone treatment or as an additive.

Metal sulfide scale dissolver for oilfield application

Compositions and methods for the use in scale inhibitor squeeze treatments are provided. In some embodiments the present disclosure provides a method including introducing a pre-flush fluid into at least a portion of a subterranean formation, the pre-flush fluid including a choline chloride chemical additive; and introducing a treatment fluid including a scale inhibitor into the portion of the subterranean formation after at least a portion of the pre-flush fluid has been introduced into the portion of the subterranean formation.

Enhanced scale inhibitor squeeze treatment using a chemical additive

Disclosed herein is a wellbore servicing fluid comprising a scale inhibitor, a surfactant, and an aqueous fluid comprising sulfate in an amount of from about 100 ppm to about 10,000 ppm based on the total weight of the aqueous fluid. The wellbore servicing fluid can be used as a fracturing fluid in a method of servicing a wellbore penetrating a subterranean formation. The wellbore servicing fluid can mitigate the formation of scales, prevent water blockage, and increase hydrocarbon production.

Wellbore servicing fluid and methods of making and using same

Provided is a method of introducing a scavenger composition into a fluid contaminated with a sulfur contaminant, mixing the scavenger composition with the fluid in a vessel, and recovering the fluid containing a reduced amount of sulfur contaminant from the effluent. The scavenger composition comprises a hydrogen sulfide scavenger and a linear anionic polymer. The linear anionic polymer is present in an amount of about 0.1% to about 50% by weight of the scavenger composition and has a number average molecular weight of about 1.0&#xd7;10to about 2.0&#xd7;10Daltons.

Increasing scavenging efficiency of HS scavenger by adding linear polymer

A method for treating a well penetrating a subterranean formation, comprises placing a treatment composition comprising polylactic acid into the well, wherein the treatment composition is in the form of pellets, a cylindrical rod, or both.

Treatment composition including a polylactic acid for a well and method relating thereto

A variety of methods, systems, and compositions are disclosed, including, in one embodiment, method of scale inhibition including: introducing a treatment fluid comprising a brine, a scale inhibitor in neutralized form, and a thermally activated acid precursor through a wellbore and into a producing formation; wherein the thermally activated acid precursor is heated to release an acid that enhances miscibility of the scale inhibitor in the brine.

Acid precursors for enhanced inhibitor placement in scale squeeze treatments

A method is disclosed that includes introducing a scavenger composition into a fluid stream contaminated with a sulfur contaminant such that the scavenger composition reacts with the sulfur contaminant to reduce an amount of the sulfur contaminant in the fluid stream, wherein the scavenger composition includes a hydrogen sulfide scavenger and an anionic linear polymer. A composition is disclosed that includes a hydrogen sulfide scavenger; and an anionic linear polymer.

A method may include: preparing or providing an aqueous fluid containing iron ions; screening at least one iron control agent against the aqueous fluid; selecting at least one iron control agent and iron control agent concentration based at least in part on the step of screening; and preparing a fracturing fluid comprising an aqueous base fluid and the at least one iron control agent wherein a concentration of the iron control agent in the fracturing fluid is greater than or equal to the selected iron control agent concentration.
