Publication number: 20230034507Abstract: A method of stimulating fluid production from a well includes defining a candidate stimulation treatment including injection of a slurry comprising acid and proppant, based on measurements of the formation. Fracture propagation and fluid transport in the formation are simulated using particle-in-cell techniques. Etching of rock by the injected acid is simulated. Rock compaction is simulated, including compaction around etched and propped portions of a fracture. A predicted fluid conductivity for acid-stimulated fracture is calculated based on the simulation of fracture geometry and a final stimulation treatment is defined based on the predicted fluid conductivity. An acid-proppant slurry is injected into the formation according to the final stimulation treatment.Type: ApplicationFiled: December 19, 2019Publication date: February 2, 2023Inventors: Rostislav Vladimirovich ROMANOVSKII, Denis Viktorovich BANNIKOV, Denis Yurievich EMELYANOV, Olga Vladimirovna NEVVONEN, Galina Gennadievna PETUKHOVA, Alexey Vladimirovich ALEKSEEV, Dmitry Sergeevich KUZNETSOV

Publication number: 20220364454Abstract: Design method for hydraulic fracturing of a reservoir is presented that maximize well production rates and minimize proppant flowback. The method comprises employing computer simulators that analyze a fracturing treatment design in the context of well properties, reservoir properties, fluids and proppants, and calculates a critical filtration velocity for a proppant pack. If the fluid flow velocity in the fracture exceeds the critical filtration velocity, there is a risk for proppant flowback. The method is applicable to wells that have not yet been fractured, as well as those that have previously undergone a fracturing treatment.Type: ApplicationFiled: October 31, 2019Publication date: November 17, 2022Inventors: Alexey Vladimirovich ALEKSEEV, Dimitry Arefievich CHUPRAKOV, Denis Viktorovich BANNIKOV, Dmitry Sergeevich KUZNETSOV, Ludmila Sergeevna BELYAKOVA, Denis Evgenievich SYRESIN, Pavel Evgenievich SPESIVTSEV, Aliya Rafailovna YULDASHEVA, Ivan Vladimirovich VELIKANOV

Patent number: 11499406Abstract: A method of predicting hydraulic fracturing and associated risks of hydraulic fracturing operation is proposed. The methods use the mathematical simulation which allow to predict the geometry of a hydraulic fracture and location of fluids, propping agents (proppant), fibers and other materials therein. Reconsidering the fracturing design allows to remedy the possible risks (overflush, screen-out, bridging, gel contamination, temperature effects).Type: GrantFiled: May 2, 2017Date of Patent: November 15, 2022Assignee: Schlumberger Technology CorporationInventors: Vadim Ismailovich Isaev, Dmitry Sergeevich Kuznetsov, Ivan Vladmirovich Velikanov, Denis Viktorovich Bannikov, Alexey Alexandrovich Tikhonov

Patent number: 9952351Abstract: A technique facilitates the study of complex fracture networks. A slot manifold is constructed with a system of branched thin channels, e.g. slots, which are joined at intersections. Fluid is flowed through the system of branched thin channels and through an intersection or intersections joining the channels in a manner which enables evaluation of fluid flow. A flow distribution device is used to allow or block flow of the fluid along specific branches of the system of branched thin channels to facilitate evaluation of fluid flow as a fluid moves through various angular changes and/or flow gap width changes from one channel to another.Type: GrantFiled: December 31, 2013Date of Patent: April 24, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dmitry Sergeevich Kuznetsov, Sergey Mikhailovich Makarychev-Mikhailov, Kira Vladimirovna Yudina, Alexey Viktorovich Zinchenko
