Patent number: 10711173Abstract: A friction reducing treatment solution that includes water, from 100 to 500,000 ppm of total dissolved solids, and from 0.5 to 3 gallons per thousand gallons of a water-in-oil emulsion containing a water soluble polymer. The total dissolved solids include at least 10 weight percent of a multivalent cation. The water-in-oil emulsion includes an oil phase and an aqueous phase, where the oil phase is a continuous phase containing an inert hydrophobic liquid and the aqueous phase is present as dispersed distinct particles in the oil phase and contains water, the water soluble polymer, and surfactants and an inverting surfactant. The water soluble polymer is made up of 30 to 60 weight percent of a non-ionic monomer, 0.5 to 25 weight percent of a carboxylic acid containing monomer, 0 to 10 weight percent of a sulfonic acid containing monomer, and 10 to 60 weight percent of a cationic monomer and makes up from 10 to 35 weight percent of the water-in-oil emulsion.Type: GrantFiled: November 21, 2017Date of Patent: July 14, 2020Assignee: SOLVAY USA INC.Inventors: Kevin Frederick, Shih-Ruey Chen, Randy Loeffler, Kailas Sawant

Patent number: 10662748Abstract: The flow of a stimulation fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of an acid soluble or acid degradable solid particulate and a composite of an acid or an acid generating compound adsorbed onto a water-insoluble adsorbent. Conductive flow of hydrocarbons from an occluded fracture may be resumed by release of the acid from the adsorbent or the acid generating compound.Type: GrantFiled: March 29, 2019Date of Patent: May 26, 2020Assignee: Baker Hughes, a GE company, LLCInventors: Harold Dean Brannon, Stephen Jan Szymczak, D.

Patent number: 10633575Abstract: Formulations and methods for stimulating the production from wells in nano-darcy shale formations are described. In one embodiment, the method includes injecting a treatment mixture containing a metal complexing agent into a nano-darcy shale formation adjacent to a well at a pressure below the fracture pressure of the formation. A sufficient contact time is allowed and then the treatment mixture is pumped from the subsurface. This has been shown to stimulate well production in shale formations. Without being held to a particular theory it appears that the metal complexing agent is binding with naturally occurring metals in the shale formation, and particularly divalent metal ions, which are then extracted with the spent fluid. This removal of naturally occurring metals may be increasing the permeability of the formation in the contact region adjacent to the well, thereby causing the observed increased production.Type: GrantFiled: January 19, 2018Date of Patent: April 28, 2020Assignee: Flex-Chem Holding Company, LLCInventor: Andrew Bryce Conway
