摘要： A fracturing fluid can include: a base fluid, wherein the base fluid comprises water; proppant; a friction reducer; and a friction reducer enhancer, wherein the friction reducer enhancer is a surfactant. The friction reducer enhancer can be in a concentration greater than or equal to a critical micelle concentration. Methods of fracturing a subterranean formation can include introducing the fracturing fluid into the subterranean formation. The friction reducer enhancer can increase the hydration rate of the friction reducer, whereby friction reduction of the fracturing fluid can occur much faster than without the friction reducer enhancer.

摘要： A slickwater fracturing fluid that includes a brine with dissolved solids, an anionic friction reducing additive, a polysaccharide, and a nanomaterial that includes nanoparticles with an average particle size between about 1 nm and about 500 nm. The polysaccharide and the anionic friction reducing additive synergistically reduce friction of the slickwater fracturing fluid so as to increase an injection rate of the slickwater fracturing fluid. Also, the polysaccharide, the anionic friction reducing additive, and the nanomaterial synergistically provide viscosity to the slickwater fracturing fluid so as to increase proppant transport capability. Also described is a method of fracturing a subterranean formation by pumping the slickwater fracturing fluid into a borehole and fracturing the subterranean formation with the slickwater fracturing fluid.

摘要： Friction reducers can be used in fluids for oil and gas operations. Friction reducers can be water-hydratable and can decrease the friction within wellbore components after fully hydrating. The friction reducer can be pre-hydrated at the well site. The friction reducer and water can be combined into a static mixer of a pre-hydration apparatus that forms a mixed fluid. The friction reducer can be retained in the pre-hydration apparatus for a sufficient period of time to allow the friction reducer to hydrate. The mixed fluid containing the pre-hydrated friction reducer can then be added to a base fluid to form a treatment fluid. The treatment fluid can be a fracturing fluid. The pre-hydrated friction reducer can provide an immediate reduction in friction to the treatment fluid as the treatment fluid is being pumped into the wellbore.
