The virtual source method has recently been proposed to image and monitor below complex and time-varying overburden. The method requires surface shooting recorded at downhole receivers placed below the distorting or changing part of the overburden. Redatuming with the measured Green’s function allows reconstruction of a complete downhole survey as if the sources were also buried at the receiver locations. Some challenges still need to be addressed in the virtual source method such as limited… CONTINUE READING
