Abstract

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.
