A polymer composition may include one or more monomeric units, with an internal crosslinker, internal breaker, scale control additive or a combination thereof.

Recovery of fluids from a subterranean formation during a well treatment operation is enhanced by injecting into the formation a treatment fluid comprising a sophorolipid.

A well servicing fluid formulated with ingredients comprising a viscosifying polymer that is a crosslinked copolymer of an ethylenically unsaturated dicarboxylic anhydride and an alkyl vinyl ether, or the di-acid thereof; a pH adjuster capable of maintaining a pH of 5.5 or greater; and a solvent. Methods of treating a well formation with the wellbore servicing fluid and methods of making the wellbore servicing fluid.

Well servicing fluid

A well treatment method includes forming a well treatment fluid by combining ingredients including a polymer, a crosslinker, an acidifying substance, and a base fluid. Crosslinking increases viscosity of the fluid during a development time. A pH decrease is controlled during the development time using the acidifying substance. The method also includes delaying the development time of the viscosity increase by controlling the pH decrease. A well treatment method includes forming a well treatment fluid by combining ingredients including a hydratable polymer, a crosslinker, an acidifying substance, and a base fluid. The method includes delaying development time of a viscosity increase by controlling a pH decrease without adding further acidifying substance after combining the polymer, crosslinker, acidifying substance, and base fluid. A well treatment fluid formulated with ingredients include a base fluid, a polymer, a crosslinker, and an acidifying substance. The acidifying substance is configured to delay development time.

Delayed viscosity well treatment methods and fluids

A well servicing fluid is formulated with ingredients comprising a viscosifying polymer that is a crosslinked copolymer of an ethylenically unsaturated dicarboxylic anhydride and an alkyl vinyl ether, or the di-acid thereof; a pH adjuster capable of maintaining a pH of 5.5 or greater; and a solvent. Methods include treating a well formation with the wellbore servicing fluid and methods also include making the wellbore servicing fluid.

A well treatment fluid containing borated galactomannan may be used to isolate a productive zone in a well having multiple productive zones. The fluid is particularly useful in treatment of wells containing a mechanical zonal isolation system in the productive zone of interest. The fluid is pumped into the well in a substantially non-hydrated form. The well treatment fluid is therefore highly effective in preferentially sealing or blocking productive zones in the formation since delayed hydration of the fluid may be controlled for up to several hours.

Disclosed is a method of rapidly hydrating a hydratable polymer, which method involves irradiating with radio frequency electromagnetic radiation, a mixture of at least the polymer and an aqueous hydrotreating medium to form a viscosified mixture of at least aqueous hydrotreating medium and hydrated polymer. Related methods of treating a subterranean formation and continuously hydrotreating a subterranean formation are also revealed.
