In January 2012, we performed seismoelectric survey at 3 sites in Thrail Oilfield. The seismoelectric signals in #3 site indicated that there is no oil reservoir. In April, the drilling company drilled at this point and only got a dry-hole. However, we detected the oil reservoir at #1 and #2 sites based on seismoelectric signals. Then in October, the report from the same drilling company show that they got the oil reservoir at 800 feet depth.
