A method of fracturing a subterranean formation penetrated by a well comprises: forming a fracturing composition comprising a carrier fluid; and a superabsorbent polymer component comprising one or more of the following: a first composite of a proppant and a first superabsorbent polymer in an unhydrated form, the first superabsorbent polymer being at least partially embedded in a void area of the proppant; a coated superabsorbent polymer; a superabsorbent material having a three-dimensional network; or a second composite of a second superabsorbent polymer and a slow-release breaker; and pumping the hydraulic fracturing composition into the subterranean formation to create or enlarge a fracture.

Fracturing fluids and methods of treating hydrocarbon formations

A well servicing fluid includes ingredients including a GLDA salt, a crosslinker, and a viscosifying agent that is not crosslinked by the crosslinker. A well treatment method includes forming a well servicing fluid with ingredients including a GLDA salt, a viscosifying agent, and a crosslinker, the GLDA salt containing a metal cation chelated with a GLDA anion. The well servicing fluid is inserted into a well in a formation. The method includes crosslinking the viscosifying agent and attaining a first viscosity of the well servicing fluid using the crosslinker. After the attaining of the first viscosity, viscosity of the well servicing fluid in the well is decreased to a second viscosity less than the first viscosity by using the GLDA anion. The GLDA salt may be a GLDA calcium salt and the crosslinker may be a zirconium crosslinker.

Well treatment methods and fluids with GLDA salt

Disclosed herein is a fracturing fluid comprising a carrier fluid; a polymer that is soluble in the carrier fluid; the polymer being a synthetic polymer, wherein the synthetic polymer comprises a labile group that is operative to facilitate decomposition of the synthetic polymer upon activation of the labile group; the synthetic polymer being operative to increase the viscosity of the carrier fluid to about 5 to about 50 centipoise; the fracturing fluid being operative to reduce friction during a downhole fracturing operation and to transport a proppant during the downhole fracturing operation; and an oxidizing agent. A method for treating a hydrocarbon-bearing formation is also disclosed herein.

Fracturing fluids and methods for treating hydrocarbon-bearing formations

Disclosed herein is a fracturing fluid comprising a carrier fluid; a polymer that is soluble in the carrier fluid; the polymer being a synthetic polymer, wherein the synthetic polymer comprises a labile group that is operative to facilitate decomposition of the synthetic polymer upon activation of the labile group; the polymer being crosslinked, the fracturing fluid having a viscosity of about 200 to about 3000 centipoise at 100 s; and an oxidizing agent. A method for treating a hydrocarbon-bearing formation is also disclosed herein.

Described herein is a method that can be used for heat treating a metal in at least one of the following processes: carburizing, carbonitriding, nitrocarburizing, and neutral carbon potential annealing operations that are used in a 1 atmosphere pressure furnace and in an atmosphere that is oxygen free and comprises nitrogen and at least one hydrocarbon.

Method and apparatus for heat treating a metal

A method and apparatus for nitriding of highly-alloyed metal article is disclosed herein. In one embodiment, the method and apparatus uses at least one nitrogen source gas such as nitrogen and/or ammonia in an oxygen-free nitriding gas atmosphere, with small additions of one or more hydrocarbons. In this or other embodiments, the method and apparatus described herein is applicable to metal articles comprising iron, nickel and cobalt based alloys and which tend to form passive oxide films on at least a portion of their surface, heated to and nitrided at a certain temperature without prior surface preparation. The apparatus includes an external gas injector comprising 50-60 Hz AC, high voltage/low-current arc discharge electrodes, activating the nitriding atmosphere stream on its way from source to nitriding furnace.

Compositions and methods of reducing a flow of aqueous liquids through a subterranean formation are provided. The compositions and methods are used for water control. The compositions include a water control additive that is prepared by reacting a soluble sodium silicate and a hydrolysable organosilane compound to produce silanol that reacts and forms a bond with the formation thereby producing a binding polysiloxane.

Method of using sodium silicate in treatment of subterranean formation for water control

A thermal insulating packer fluid contains at least one water superabsorbent polymer and optionally water and/or brine, and a viscosifying polymer. The composition is capable of inhibiting unwanted heat loss from production tubing or uncontrolled heat transfer to outer annuli. The viscosity of the composition is sufficient to reduce the convection flow velocity within the annulus.

Methods of using water-superabsorbent polymers to reduce heat transfer

Unwanted heat loss from production tubing or uncontrolled heat transfer to outer annuli is inhibited by introduction into the annuli a thermal insulating packer fluid or a riser fluid containing a zwitterionic surfactant, an alcohol and a brine. The viscosity of the composition is sufficient to reduce the convection flow velocity within the annulus. The invention has particular applicability with high density brines.

Methods and compositions for thermal insulation

A method of enhancing the productivity of a subterranean formation penetrated by a gas, oil or geothermal well consists of introducing into the formation and/or well a pumpable polymerizable fluid comprising a crosslinkable, monofunctional alkene, multi-functional alkene (such as a difunctional alkene), a heat inducible free radical initiator and brine. The fluid may be used in the thermal insulation of production tubing or transfer pipes and hydraulic fracturing.

Method of using crosslinkable brine containing compositions

Liquid breakers can be used in methods and compositions for acid fracturing formations. The fracturing fluid includes a liquid breaker that decreases the viscosity of the fracturing fluid over time. The liquid breaker can also be produced in situ. The liquid breaker includes fluoroboric acid.

Method of using water-superabsorbent polymer in production tubing and pipes

A thermal insulating composition containing an organic solvent of low thermal conductivity and a gelling agent hydratable in the solvent is useful for controlling heat transfer from a production tubing or transfer pipe in a wellbore to a surrounding annuli and/or the environment. Further, the composition is capable of reducing convection flow velocity within the annulus surrounding production tubing or a transfer pipe.
