Patent number: 9797232Abstract: A method for producing minerals and, more specifically, for producing hydrocarbons, by hydraulic fracturing of the rock, can be used for the optimization of formation fracturing crack processing conditions. The method includes splitting a main stream of a propping agent suspension in a fluid at a mixer output into at least two flows having different volume delivery rates, and comingling the at least two flows before delivering to the hydraulic fracturing zone.Type: GrantFiled: February 23, 2015Date of Patent: October 24, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Oleg Medvedev, Anatoly Vladimirovich Medvedev, John Lassek

Patent number: 9316087Abstract: In downhole treatments in the oilfield, ball sealers seated in perforations may not fully seal and may leak fluid through gaps and asperities between the balls and the perforations. A method is given for improving the sealing of ball sealers in perforations by adding a sealing agent that forms a plug in the gaps and severely restricts or eliminates fluid flow. The sealing agent is preferably degradable or soluble, malleable fibers slightly larger than the gaps. Optionally, the particles may be non-degradable, rigid, of different shapes, and smaller than the gaps but able to bridge them. Mixtures of sealing agents may be used. The sealing agent may be added with the ball sealers, after the ball sealers, or both.Type: GrantFiled: January 20, 2015Date of Patent: April 19, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Curtis L. Boney, Jason Swaren, John Lassek, Ricardo Ariza, Desmond E. Rees, David Ryan Simon, Michael A. Dardis, Darrell P. Davis
