We conducted a crosswell seismic project in April 2002 in the Ma production area of Jianghan oil field in central Hubei Provice, P.R. China. This part of the Jianghan fault basin contains complex faults that dominate the reservoir zone, and they significantly affect flow paths and fluid distribution. Therefore, it is critical to understand the fault structure distribution in this area at the reservoir scale in order to develop and enhance production.

The Ma area has been surveyed with 3D surface seismic and most wells are extensively logged. This area is known to be a seismically poor data area due...
