Patent number: 11371333Abstract: Systems and methods are described for generating visualizations of reservoir simulations with embedded fracture networks by using data representing a subterranean formation to obtain a matrix grid with an embedded fracture network. The matrix grid can be separated into matrix grid control volumes, and the fracture network can be separated into fracture network control volumes. Locations of fracture-fracture intersections between the fracture network control volumes and locations of matrix-fracture intersections between the matrix grid control volumes and the fracture network control volumes can be identified. Based on the identified intersections, shapes of the fracture network control volumes can be determined and a visualization of the matrix grid with the embedded fracture network can be generated with a grid representing the matrix grid and an embedded plane within the gird, where the embedded plane is based on the shapes of each fracture network control volume.Type: GrantFiled: June 22, 2016Date of Patent: June 28, 2022Assignee: Schlumberger Technology CorporationInventor: Hussein Mustapha
