摘要： Treatment methods including preparation of an aqueous treatment fluid composition composed of a carboxy modified polymer, a crosslinking agent, and a viscosifying quaternary amine salt, and subsequently introducing the composition into a the formation to treat. The treatment method is particularly useful for fracturing a subterranean formation. The polymer and crosslinker may be premixed and injected into a wellbore, then mixed therein with the quaternary amine salt to treat the formation. In another aspect, the polymer, crosslinker, and quaternary amine salt are mixed, injected into a wellbore, and introduced in the formation for treatment.

摘要： A fluid loss control pill or solution includes a polymer having a functional group that can be hydrolyzed by a base or a nucleophile. A method for fluid loss control in a subterranean formation includes placing a fluid loss control pill or solution in a wellbore penetrating the subterranean formation, wherein the fluid loss control pill or solution comprises a polymer having a functional group that can be hydrolyzed by a base or a nucleophile; and converting the polymer into a soluble form by hydrolyzing the functional group with a base or a nucleophile, when fluid loss control is no longer needed.

摘要： A wellbore treatment fluid is formed from an aqueous medium, a gas component, a viscosifying agent, and a surfactant. The surfactant is represented by the chemical formula: [R—(OCH2CH2)m—Oq—YOn]pX wherein R is a linear alkyl, branched alkyl, alkyl cycloaliphatic, or alkyl aryl group; O is an oxygen atom; Y is either a sulfur or phosphorus atom; m is 1 or more; n is a integer ranging from 1 to 3; p is a integer ranging from 1 to 4; q is a integer ranging from 0 to 1; and X is a cation. The fluid may be used in treating a subterranean formation penetrating by a wellbore by introducing the fluid into the wellbore. The fluid may be used in fracturing a subterranean formation penetrated by a wellbore by introducing the fluid into the formation at a pressure equal to or greater than the fracture initiation pressure.

摘要： A method of introducing friction reducing agents within a wellbore penetrating a subterranean formation during a gravel packing operation is accomplished by providing a length of tubing located downhole within the wellbore for conducting fluids within the wellbore through the tubing during circulating of gravel packing fluids introduced from the surface within the wellbore. At least a portion of the tubing is surrounded by a screen for screening out particulate matter during the gravel packing operation. An annular space is defined between an interior of the screen and the exterior of the tubing. A friction reducing agent is dispensed from a dispensing apparatus that locates downhole with the tubing. The dispensing apparatus includes a housing and a chamber disposed within the housing that has one or more outlets that open into the annular space defined by the screen and tubing for dispensing the friction reducing agent. The dispensing apparatus further includes a piston and a trigger mechanism for actuating the piston. When the trigger mechanism is activated to actuate the piston, the friction reducing agent is dispensed through the one or more outlets at a position downhole remote from the surface during the circulating.
