Patent number: 11913314Abstract: A method is offered to predict and prevent the event of fracture hit (direct fluid communication) between a parent well and a child (active) well. The growth of a child well creates 3D stress field in the vicinity of a parent well. The growth of a child well is simulated using the geomechanic-transport model. A model of interaction between the child well and parent well is provided. The simulations for different job designs create a set of pressure scenario in the parent both for the cases with and without fracture hit (fracture hit catalogue). Comparison (matching) of actual pressure data in the parent and child well with the pre-calculated pressure scenarios indicate the risk of fracture development with a fracture hit, which means a stop in fracturing stimulation.Type: GrantFiled: December 16, 2020Date of Patent: February 27, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Roman Korkin, Andrey Fedorov, Artem Kabannik, Kira Vladimirovna Yudina, Dmitry Badazhkov, Jared Bruns, Xiaowei Weng, Aleksandra Khudorozhkova
