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.

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

Publication number: 20110083850Abstract: The invention relates to the oil-and-gas production industry and can be used for enhancement of the production of oilfield wells as it prevents the fracture from closing by pumping of propping granules (proppant) during the hydraulic fracturing of oil-producing formations. Higher stimulation of a reservoir through using hydraulic fracturing is provided with the proppant as particulate with spherical or elliptic form, made of ceramic, polymer, metal, or glass and having higher roughness than regular proppant, wherein the surface roughness is nonuniform and described by two criteria A and B, varying in the intervals: A =0.0085?0.85; B=0.001?1.0. The proppant manufacturing method comprising the preparation of raw material, mixing, granulation, drying, firing, wherein an additional stage of creation of surface roughness is added at the granulation stage and/or the firing stage.Type: ApplicationFiled: December 17, 2010Publication date: April 14, 2011Inventors: Evgeny Borisovich Barmatov, Elena Mikhailovna Pershikova, Konstantin Mikhailovich Lyapunov, Jonathan Abbott

Publication number: 20080156489Abstract: This invention relates to the oil and gas industry, in particular, to methods affecting the formation productivity at the oil and gas production stage. A method for fracture propping in a subsurface layer, which ensures a reliable protection of wells from the proppant carryover from the fracture, has been proposed. According to the proposed method, a fracturing fluid is mixed with a propping agent and particulate binding material wherein the particles have an average length-to-width ratio of less than or equal to about 10; thereafter, a formation fracturing process is implemented. Then, the particulate binding material hardens and forms a homogenous firm mass with the propping agent, which impedes the closing of the fracture and precludes proppant carryover from the fracture. Or, a fracturing fluid composition obtained by mixing a propping agent with a binding compound in the form of a powder whose size varies from about 1 to about 500 ?m.Type: ApplicationFiled: December 18, 2007Publication date: July 3, 2008Inventors: Elena Mikhailovna Pershikova, Evgeny Borisovich Barmatov, Konstantin Mikhailovich Lyapunov
