Polymers and fracturing fluid compositions including a base fluid, an effective amount of a hydratable polymer composition including one or more gel-forming hydratable polymers, a friction reducer composition including hydrolyzed or partially hydrolyzed hydrolyzable polymers and copolymers, a cross-linking composition in an amount sufficient to crosslink the one or more gel-forming hydratable polymers to form crosslinked structures within the fracturing fluid composition with or without a proppant and methods including combining an aqueous fluid and an oleaginous fluid to prepare an invert emulsion comprising a polymerizable composition, degassing the invert emulsion under an extensional flow regime through an elongated passageway of an extender and thereby removing oxygen to produce a degassed invert emulsion and compositions and methods including a hydratable additive concentrate comprising a hydratable additive that is at least substantially hydrated and a hydrating liquid, wherein the hydratable additive concentrate is a mixture produced according to a method that includes flowing a hydrating liquid in a extensional flow regime through an elongated passageway of an extender.

Fracturing fluid compositions and methods for making and using same

Fracturing fluid compositions including a base fluid including a high TDS produced and/or flow back water, brackish water, RO reject water, clear brine, and mixtures thereof with or without added fresh water and systems, and methods for making and using same, where the method includes: (a) adding a first buffer to adjust the pH of a base fluid to an acidic pH, (b) adding a hydratable polymer or polymer slurry to the base fluid to form a hydratable polymer fracturing fluid, (c) adding a cross-linking composition to the hydratable polymer fracturing fluid to form a pre-cross-linked fracturing fluid, and (d) if needed, adding a second buffer to the pre-cross-linked fracturing fluid to adjust the pH of the pre-cross-linked fracturing fluid to form a viscosified fracturing fluid having a crosslinked structure.

Compositions and methods for cross-linking hydratable polymers using produced water

Methods include producing a gelled sanitizer composition, including preparing a hydrating fluid composition including water and one or more of alcohol and peroxide; preparing a hydratable additive; and combining the hydrating fluid composition and the hydratable additive to produce a gelled composition. Methods also include flowing a hydrating liquid composition in an extensional flow regime through an elongated passageway of an extender, wherein the hydrating liquid composition includes water and a C2-C10 solvent, and a flow rate of the hydrating liquid composition and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater; and adding a hydratable additive to the hydrating liquid composition in the elongated passageway to produce a mixture comprising the hydratable additive that is at least partially hydrated.

Systems and methods for the production of gelled sanitizer compositions under extensional flow conditions

A method includes combining an aqueous fluid and an oleaginous fluid to prepare an invert emulsion comprising a polymerizable composition, degassing the invert emulsion under an extensional flow regime through an elongated passageway of an extender and thereby removing oxygen to produce a degassed invert emulsion. A flow rate of the invert emulsion and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater. The method also includes transferring at least a portion of the degassed invert emulsion to the second extender at one or more time intervals and returning the portion of the degassed invert emulsion to the reactor, and isolating a polymer product from the degassed invert emulsion. A flow rate of the invert emulsion and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater.

Systems and methods of polymerization under extensional flow conditions

Compositions include a hydratable additive concentrate comprising a hydratable additive that is at least substantially hydrated and a hydrating liquid, wherein the hydratable additive concentrate is a mixture produced according to a method that includes flowing a hydrating liquid in a extensional flow regime through an elongated passageway of an extender, wherein a flow rate of the hydrating liquid and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater; and adding a hydratable additive to the hydrating liquid in the elongated passageway to produce a mixture comprising the hydratable additive that is at least partially hydrated.

Systems and methods of hydrating polymer additives

A method includes flowing a hydrating liquid in an extensional flow regime through an elongated passageway of an extender, wherein a flow rate of the hydrating liquid and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater. A hydratable additive is added to the hydrating liquid in the elongated passageway to produce a mixture comprising the hydratable additive that is at least partially hydrated.

The present disclosure relates to a crosslinking composition for use in crosslinking an aqueous suspension of guar, for use as a well treatment fluid and/or proppant carrier fluid for natural gas extraction. The present crosslinking composition is an aqueous suspension of hydroboracite. The composition may also comprise varying amounts of borax, canola oil, xanthan, glycerol, and/or NaOH. The composition may be selected to effect a desired delay in the crosslinking reaction in order to customize the viscosity and reaction time to the method of use, thereby maximizing proppant delivery while minimizing pump pressure.

Borate crosslinker

A heat pump liquid heater for heating a liquid comprising: a heat pump; a liquid tank in heat communication with the heat pump, wherein the liquid tank comprises the liquid; and at least one metal condenser tube immersed into the liquid, wherein the metal condenser tube forms at least one coil. The metal condenser tube has a flattened double-tube configuration and a cross-section defined by concentric ovals such that at least a portion of the concentric ovals is in contact with one another thereby minimizing space between the flattened double-tubes. The heat pump comprises a tube-in-tube heat exchanger and a compressor, wherein the tube-in-tube heat exchanger recovers heat from refrigerant returning from the liquid tank and transfers the recovered heat to refrigerant going to the compressor thereby superheating the refrigerant.

Heat pump liquid heater

Polymer suspensions prepared with non-aqueous, oil-free carrier fluids, for use in oil or gas well servicing. The polymer suspensions typically comprise a hydrophilic polymer, an organic clay, a stabilizer, and a carrier fluid selected from propylene glycol and butylene glycol. The addition of isopropyl alcohol, a polar activator, lowers the viscosity of the suspension. The further addition of neopentyl glycol further lowers viscosity and improves cross-linking of the polymer. The composition is both stable and environmentally acceptable.
