Publication number: 20220340809Abstract: 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.Type: ApplicationFiled: April 23, 2021Publication date: October 27, 2022Applicant: Halliburton Energy Services, Inc.Inventors: Leiming Li, Chunli Li, Liang Xu, Philip D.

Patent number: 11479715Abstract: 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.Type: GrantFiled: May 22, 2020Date of Patent: October 25, 2022Inventors: Leiming Li, Liang Xu, Todd Collier
