Publication number: 20170284179Abstract: Rows of horizontal production wells and rows of horizontal injection wells are drilled and alternating in a formation. The horizontal production wellbores and the horizontal injection wellbores are placed in the direction of a minimum horizontal stress in the formation. Within casing strings of the wells, at least two hydraulic frac ports are installed and multi-stage fracturing is performed through them in the production wells and in the injection wells in such way that fractures are formed along each production well and along each injection well in a direction perpendicular to the horizontal wellbore, the hydraulic fractures in the injection wells are offset from the hydraulic fractures in the production wells. The production and the injection wells are put into operation by injecting a fluid into the injection wells, a flow rate and/or a volume of the injected fluid are controlled in such a way that the injection pressure is below a fracturing pressure.Type: ApplicationFiled: March 31, 2017Publication date: October 5, 2017Inventors: Kreso Kurt Butula, Vladimir Evgenievich Stashevsky, Vladimir Viktorovich Malyshev, Sergei Vereschagin, Christopher Hopkins

Publication number: 20160312594Abstract: The method for orienting hydraulic fractures in a subterranean formation comprises injecting a first fluid into a first horizontal wellbore penetrating the subterranean formation and open to the formation in at least one specified segment and pressurizing the first fluid in the first wellbore to create a stress field around each specified segment of the first wellbore. A second pressurized fracturing particle-laden fluid is simultaneously injected into a second horizontal wellbore open to the formation in at least one specified segment and vertically spaced apart from the first wellbore for inducing fractures propagating from the specified segments of the second wellbore towards the specified pressurized segments of the first wellbore.Type: ApplicationFiled: April 20, 2016Publication date: October 27, 2016Inventors: Fikri John Kuchuk, Bertrand Theuveny, Andrei Alexandrovich Osiptsov, Kreso Kurt Butula

Patent number: 9447673Abstract: A proppant pack may be formed in a fracture that extends from a wellbore formed in a subterranean formation and is accomplished through different methods. The methods involve providing multiple spaced apart proppant slugs within a hydraulic fracturing fluid that is introduced into the wellbore at a pressure above the fracturing pressure of the formation.Type: GrantFiled: May 17, 2010Date of Patent: September 20, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Anatoly Vladimirovich Medvedev, Oleg Medvedev, Alexander Vuacheslavovich Mikhaylov, Christopher N.

Publication number: 20150300157Abstract: A method of tracking a treatment fluid in a subterranean formation penetrated by a wellbore provides for injecting the treatment fluid with the plurality of tracer agents into the well and the formation. The tracer agents are high viscous liquid droplets having a diameter of not more than 1000 nm. Location and distribution of the treatment fluid is determined by detecting changes in physical properties of the formation caused by arrival of the treatment fluid comprising the plurality of the tracer agents.Type: ApplicationFiled: April 24, 2015Publication date: October 22, 2015Inventors: Ashok Belani, Dimitri Vladilenovich Pissarenko, Kreso Kurt Butula, Sergey Sergeevich Sanfonov, Oleg Yurievich Dinariev, Oleg Mikhailovich Zozulya

Patent number: 7578346Abstract: A material and method for treating a fractured formation penetrated by a wellbore includes providing a quantity of resin coated particles having a particle size of from about 0.2 mm to about 2.35 mm. A quantity of smaller deformable or non-deformable particles is combined with the resin coated particles to form a generally uniform consolidated particle pack when mixed together and subjected to at least one of heat and pressure. A slurry of the particles is formed with a carrier fluid capable of suspending the particles. The slurry of particles is introduced into the wellbore of the formation. The resin coated particles and smaller deformable particles thus may form a consolidated particle pack in at least a portion of the fractures of the formation.Type: GrantFiled: November 8, 2006Date of Patent: August 25, 2009Assignee: Schlumberger Technology CorporationInventors: Diankui Fu, Kreso Kurt Butula
