Patent number: 10030495Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) and proppant-spacing filler material (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the material (24), and removing the filler material (24) to form open channels (26) around the pillars (28). The filler material can be dissolvable particles, initially acting as a consolidator during placement of the proppant in the fracture, and later dissolving to leave flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.Type: GrantFiled: February 23, 2015Date of Patent: July 24, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Fedor Nikolaevich Litvinets, Andrey Vladimirovich Bogdan, Sergey Mikhailovich Makarychev-Mikhailov, Oleg Medvedev, Alejandro Pena, Konstantin Mikhailovich Lyapunov, Alexander Vuacheslavovich Mikhaylov, Timothy M.

Patent number: 9863230Abstract: A method of injecting well treatment fluid including proppant and proppant-spacing filler material through a wellbore into the fracture, heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands spaced apart by the material, and removing the filler material to form open channels around the pillars for fluid flow from the formation through the fracture toward the wellbore. The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The filler material can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and/or to inhibit settling of the proppant.Type: GrantFiled: June 12, 2012Date of Patent: January 9, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Fedor Nikolaevich Litvinets, Andrey Vladimirovich Bogdan, Sergey Mikhailovich Makarychev-Mikhaliov, Oleg Medvedev, Alejandro Pena, Konstantin Mikhailovich Lyapunov, Alexander Vuacheslavovich Mikhaylov, Timothy M.

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: 9121272Abstract: A method of fracturing multiple zones within a wellbore formed in a subterranean formation is carried out by forming flow-through passages in two or more zones within the wellbore that are spaced apart from each other along the length of a portion of the wellbore. The flow-through passages within each zone have different characteristics provided by orienting the flow-through passages in directions in each of the two or more zones relative to a selected direction to provide differences in fracture initiation pressures within each of the two or more zones. A fracturing fluid is introduced into the wellbore in a fracturing treatment. The fracturing fluid in the fracturing treatment is provided at a pressure that is above the fracture initiation pressure of one of the two or more zones to facilitate fracturing of said one of two or more zones while remaining below the fracture initiation pressure of any other non-fractured zones of the two or more zones.Type: GrantFiled: August 5, 2011Date of Patent: September 1, 2015Assignee: Schlumberger Technology CorporationInventors: Dmitry Ivanovich Potapenko, Bruno Lecerf, Olga Petrovna Alekseenko, Christopher N Fredd, Elena Nikolaevna Tarasova, Oleg Medvedev, Matthew Robert Gillard

Publication number: 20150204177Abstract: A technique facilitates treatment of a subterranean formation. A proppant and a proppant carrier fluid are delivered to a subterranean location for treatment of the formation. At the subterranean location, heterogeneities of proppant structures are generated with the proppant and the proppant carrier fluid. The heterogeneous proppant structures are then transported into the subterranean formation to improve conductivity.Type: ApplicationFiled: August 7, 2012Publication date: July 23, 2015Applicant: Schlumberger Technology CorporationInventors: Ruslan Ramilevich Isangulov, Konstantin Viktorovich Vidma, Oleg Medvedev, Konstantin Mikhailovich Lyapunov, Anatoly Vladimirovich Medvedev, Alexander Vuacheslavovich Mikhaylov, Rod William Shampine, Geza Horvath Szabo
