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: 9863228Abstract: A system includes a regional blending facility having a number of bulk receiving facilities, where each bulk facility receives and stores a particle type having a distinct size modality, a bulk moving device that transfers particles between the bulk receiving facilities and of a blending/continuously receiving vessel and/or a mixer, and a carrying medium vessel. The mixer receives particles from the blending/continuously receiving vessel and/or the bulk moving device, receives a carrying medium from the carrying medium vessel, mixes the particles with the carrying medium, and provides a mixed treatment fluid. The system includes a fluid conduit that fluidly couples a wellsite location with the regional blending facility, where the fluid conduit delivers the mixed treatment fluid to the wellsite and/or delivers produced fluid from a wellbore positioned at the wellsite to the regional blending facility.Type: GrantFiled: March 8, 2013Date of Patent: January 9, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Rod Shampine, Edward Leugemors, Timothy M. Lesko

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: 9140109Abstract: A technique enables improvements in hydraulic fracturing treatments on heterogeneous reservoirs. Based on data obtained for a given reservoir, a fracturing treatment material is used to create complex fractures, which, while interacting with the interfaces and planes of weakness in the reservoir, develop fracture connectors, e.g. step-overs, which often grow for short distances along these planes of weakness. The technique further comprises closing or sealing at least one of the fracture connectors to enable reinitiation of fracturing from the truncated branches, and to subsequently develop additional connectors. As a result, the overall fracturing becomes more complex (more branches and more surface area per unit reservoir volume is created), which leads to an increase in the effective fracture area and improved fluid flow through the reservoir.Type: GrantFiled: September 29, 2010Date of Patent: September 22, 2015Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Roberto Suarez-Rivera, Dean M. Wulberg, Timothy M. Lesko, Marc Jean Thiercelin, Gisele Thiercelin
