Patent number: 11119248Abstract: The present invention is related to a method for estimating the fractured volume in a reservoir domain, said fractured volume generated by injecting a high pressure fluid into the reservoir domain. The high pressure fluid generates new fractures allowing a more effective drainage of porous rocks, generally identified as geological material, containing oil or gas. As a result, the effective reservoir volume increases. According to embodiments of the invention, the method provides a dynamic estimation of the fractured volume taking into account the evolution of the rock and the fractures. In other embodiment, the evolution of the fractured volume is estimated by generating an envelope surrounding the induced fractures allowing a better estimation of the fractured volume.Type: GrantFiled: August 20, 2018Date of Patent: September 14, 2021Assignees: REPSOL, S.A., UNIVERSIDAD POLITÉCNICA DE CATALUÑAInventors: Lakshmikantha Mookanahallipatna Ramasesha, José Alvarellos Iglesias, José María Segura Serra, Ignacio Carol Vilarasau, Daniel Garolera Vinent, Pere Prat Catalan

Patent number: 10571603Abstract: The object of the invention is a method implemented in a computer for the numerical simulation of a porous medium that may comprise multiple interacting hydraulic fractures in continuous or naturally fractured medium. The method calculates numerically the propagation of a crack, or set of cracks, for instance under the fluid pressure imposed artificially through a well or perforation in a rock mass. This is accomplished by using the Finite Element Method and the special elements named zero-thickness interface or joint elements in the specialized literature, which are pre-inserted along all potential crack paths in the rock mass (pre-existing natural and artificial fractures plus main potential new fracture paths).Type: GrantFiled: February 18, 2015Date of Patent: February 25, 2020Assignees: REPSOL, S.A., UNIVERSIDAD POLITÉCNICA DE CATALUÑAInventors: Lakshmikantha Mookanahallipatna Ramasesha, José María Segura Serra, Jose Alvarellos Iglesias, Ignacio Carol Vilarasau, Pere Prat Catalan, Ignasi Aliguer Piferrer, Daniel Garolera Vinent
