Patent number: 11753917Abstract: When a child well is hydraulically fractured near the depleted reservoir volume surrounding a previously produced parent well, it is economically efficient to deliver proppant to the formation volume and fractures not reached by the parent well. A fracture length, which is the distance fluid travels from the child well to the depleted region, is calculated as a function of fracture stage. From identified trends in fracture length, fracture length for future stages can be predicted. Based on predicted fracture length, the slurry or treatment volume to cause well interference can be estimated. Proppant concentration or fracturing stage design can be adjusted so that the well interference volume is larger than the treatment volume and proppant is efficiently delivered to the child well fractures.Type: GrantFiled: September 25, 2020Date of Patent: September 12, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Dinesh Ananda Shetty, William Owen Alexander Ruhle, Srividhya Sridhar

Patent number: 11739258Abstract: Proppant particulates are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. In complex fracture networks, it can be difficult to deposit proppant particulates fully within the fractures. In addition, low crush strengths may result in problematic fines formation. Polyaromatic hydrocarbons, commonly encountered in various refinery process streams, may serve as an advantageous precursor to proppant particulates. Polyaromatic hydrocarbons may undergo crosslinking under acid-catalyzed conditions in an aqueous solvent in the presence of a surfactant to form substantially spherical particulates that may serve as effective proppant particulates during fracturing operations. In situ formation of the proppant particulates may take place in some cases.Type: GrantFiled: December 27, 2022Date of Patent: August 29, 2023Assignee: ExxonMobil Technology and Engineering CompanyInventors: Peter A. Gordon, Huaxing Daniel Zhou
