Patent number: 11268914Abstract: Systems, tools, and methods for optimizing fracturing schedules located along a horizontal wellbore include obtaining drilling cuttings during a drilling operation representative of a predetermined interval of the horizontal wellbore, performing at least one analytical process on the obtained drilling cuttings to determine at least one geomechanical property of the interval of the obtained drilling cuttings for the interval, generating a formation analysis estimation for the interval from the, wherein the formation analysis estimation comprises at least one of (i) a brittleness of the formation at the interval or (ii) a minimum horizontal stress of the formation at the interval, and based on the formation analysis estimation, at least one of (i) configuring a super-stage for deployment to the interval to perform a fracturing operation or (ii) designing a fracturing schedule to be performed to frac the formation at the interval.Type: GrantFiled: January 13, 2017Date of Patent: March 8, 2022Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Umesh Prasad, Sergey Stolyarov, David Gadzhimirzaev, Robert Samuel Hurt, Eduardo Adrian Cazeneuve, Frank Walles, Geoffrey Cave, Said D.

Patent number: 11150369Abstract: Systems, methods, and computer-readable medium for generating a three-dimensional fracture network model are provided. The method can include receiving reflected acoustic signal measurements acquired in response to emission of acoustic waves by one or more sensors disposed in a wellbore formed within a target region. Each reflected acoustic signal measurement represents a strength of a reflected acoustic wave as a function of time measured in at least one predetermined direction oriented with respect to an axis of the wellbore. A fracture extension estimate is generated for each of the reflected acoustic signal measurements. A three-dimensional fracture network model is generated corresponding to the fracture extension estimates generated for each of the plurality of reflected acoustic measurements. The generated fracture network model is output for display or use in modeling environments.Type: GrantFiled: November 25, 2019Date of Patent: October 19, 2021Assignee: Baker Hughes, a GE Company, LLCInventors: David Katz, Sergey Stolyarov, Eduardo Adrian Cazeneuve, Karim Sabaa, Gennady Koscheev

Patent number: 10677036Abstract: A method for performing a fracture operation. A log of a formation parameter is obtained for a formation surrounding a wellbore in which the fracture operation is to be implemented. A relation is determined between the formation parameter and a parameter of the fracture operation. A value of the parameter of the fracture operation is selected based on the relation and a value of the formation parameter.Type: GrantFiled: March 29, 2018Date of Patent: June 9, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Sergey Stolyarov, Junjie Yang, Sergey Kotov, David Gadzhimirzaev, Jason Wayne Simmons

Publication number: 20080182761Abstract: The productivity of sandstone or carbonate formations is enhanced by contacting the formation with a deformable particulate and a HF-containing acidizing solution. The deformable particulates create a partial monolayer in the formation while the HF-containing acidizing solution differentially etches the rock around the deformable particulate. The surface of the formation is partially blocked from reaction with the acidizing solution by the creation of the partial monolayer. Conductive channels are therefore created on the surface of the formation. The deformable particulates deform on closure. As the closure stress increases, the formation faces compress the non-dissolved, sandwiched formation points. These points function as pillars of un-reacted formation and act similar to a partial monolayer of proppant, providing the highly conductive channels.Type: ApplicationFiled: January 25, 2008Publication date: July 31, 2008Inventors: Christopher John Stephenson, Jeffrey C. Dawson, Leonard J. Kalfayan, Qi Qu, Sergey Stolyarov
