Mapping subsurface fractures using their elastic nonlinear response

Natural open fractures and joints play an important role in production from carbonate and consolidated sandstone fractured reservoirs because the fluid flow is strongly influenced by the fracture orientation and the fracture density. The ability to delineate and accurately map the fractures represents critical information that is necessary for field development strategies.Quite often horizontal wells are used to improve production efficiency from fractured reservoirs. However, due to the absence of the information that accurately maps the orientation and location of the conductive faults, joints, and fractures, there is a risk that water cut from a horizontal well may increase rather than...
