Controlled source fracture monitoring

摘要

Reservoir fractures are visualized using electrically active proppants to carry electric signals throughout the fracture. The electric signals are easily detected at the surface using RF antennae and a three-dimensional image of the fracture is generated.

主权项

1. A method of imaging a fracture comprising:
a) packing an electrically active (EA) proppant into a fracture, b) charging said proppant with an electric signal, wherien the electrical signal is encoded; c) detecting said electric signal with one or more surface antennae, and d) imaging said fracture using the detected eletric signal (c), wherein said EA proppant comprises an EA sized proppant particle, an EA fracture fluid or both EA sized proppant particle and EA fracture fluid.
