Patent number: 9624421Abstract: Proppants for use in fractured or gravel packed/frac packed oil and gas wells are provided with a contaminant removal component to remove one or more of the contaminants found in subterranean water/hydrocarbon from a production well. The water/hydrocarbon cleaning proppant solids may be used as discrete particles in a proppant formulation, as a coating on proppant solids in pores of a porous proppant solid or as part of the proppant's internal structure. The contaminant removal component removes contaminants, especially dissolved contaminants, in the subterranean water or hydrocarbon before the water/hydrocarbon leaves the well. For those contaminant removal components that can be regenerated, such as ion exchange resins, a measured quantity of an acidic regeneration solution can be injected into the fractured stratum for regeneration and recovered when the well resumes production.Type: GrantFiled: June 25, 2014Date of Patent: April 18, 2017Assignee: Preferred Technology, LLCInventors: Robert Ray McDaniel, Avis Lloyd McCrary

Patent number: 9556377Abstract: Chelating agents are often used in conjunction with stimulation operations in a subterranean formation to address the presence of certain metal ions therein. Hydrophobically modified chelating agents can be used to form metal-ligand complexes in a subterranean formation that can sometimes exhibit significantly different behavior than do their more water-soluble variants. Methods for treating a subterranean formation can comprise: providing a treatment fluid comprising a hydrophobically modified aminopolycarboxylic acid chelating agent, the chelating agent comprising an N-substitution having no carboxylic acid groups and about 6 carbon atoms or more; introducing the treatment fluid into a subterranean formation; and complexing metal ions in the subterranean formation with the chelating agent to form a metal-ligand complex.Type: GrantFiled: October 8, 2013Date of Patent: January 31, 2017Assignee: Halliburton Energy Services, Inc.Inventors: Aaron Michael Beuterbaugh, Enrique Antonio Reyes, Alyssa Lynn Smith

Patent number: 9540903Abstract: An emulsion is mixed with fibers while the emulsion is moving through a surface tubing using a venturi. The fiber/emulsion mixture is injected into a pressurized tank and the pressurized fiber/emulsion mixture is injected from the pressurized tank into a desired location in a wellbore. Pumps and pressure boosters may be used to move the fluid. Alternatively, an emulsion and a fiber suspension is provided and a first downhole tubing disposed in a wellbore conveys the emulsion downhole while a second downhole tubing disposed in the wellbore and circumferentially enclosing all or part of the first downhole tubing conveys the fiber suspension downhole. The first downhole tubing has nozzles through which the emulsion passes into the second downhole tubing and the emulsion and the fiber suspension mix. The mixture exits the second downhole tubing through ports at a desired location in the wellbore.Type: GrantFiled: October 16, 2014Date of Patent: January 10, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Mustapha Abbad, Stephen John Remane Dyer

Patent number: 9152646Abstract: A creation order of content items can generally be determined by a metadata creation time associated with the content items. In some instances, multiple content items can be associated with the same metadata creation time. To determine the order of content items associated with the same metadata creation time, a files system modification time for the content items can be accessed. The file system modification time may indicate time in a smaller time increment than the metadata creation time. If the creation order of the content items cannot be determined from the file system modification time, the names of the content items can be analyzed to determine if they indicate a creation order. Alternatively the order the content items are placed in memory can be used to determine the creation order. Metadata identifying the determined creation order of the content items can be appended to the content items.Type: GrantFiled: April 5, 2013Date of Patent: October 6, 2015Assignee: Dropbox, Inc.Inventors: Alex Sydell, Kyle Consalus
