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.

Patent number: 8584755Abstract: The invention provides economically effective methods for hydraulic fracturing a subterranean formation that ensure improvement of the hydraulic fracture conductivity because of forming strong proppant clusters uniformly placed in the fracture throughout its length. One of these methods comprises: a first stage comprising injection of fracturing fluid into a borehole, the fluid containing thickeners to create a fracture in the formation; and a second stage comprising introduction of proppant into the injected fracturing fluid to prevent closure of the created fracture, and further, comprising introducing an agent into the fracturing fluid to provide formation of proppant clusters in the created fracture and channels for flowing formation fluids.Type: GrantFiled: November 18, 2011Date of Patent: November 19, 2013Assignee: Schlumberger Technology CorporationInventors: Dean M.

Patent number: 8540024Abstract: Hydraulic fracturing an individual reservoir fracturing layer of a subterranean formation to produce heterogeneous proppant placement is given in which pillars of proppant are placed such that the pillars do not extend the entire height of the fracture (for a vertical fracture) but are themselves interrupted by channels so that the channels between the pillars form pathways that lead to the wellbore. The method combines methods of introducing slugs of proppant-carrying and proppant-free fluids through multiple clusters of perforations within a single fracturing layer of rock, with methods of ensuring that the slugs exiting the individual clusters do not merge.Type: GrantFiled: July 3, 2007Date of Patent: September 24, 2013Assignee: Schlumberger Technology CorporationInventors: Ivan Vitalievich Kosarev, Oleg Olegovich Medvedev, Anatoly Vladimirovich Medvedev, Ian Walton
