In January 2015, Seismo Electronics LLC. completed the seismoelectric survey project for its client-Sinopec Shengli Oilfield Company. Our geophysicists used our instrument to detect reservoir 2000-4000m below ground surface. We provided three recommended drilling locations to our client, which all match the client’s existed reservoir analysis results. Our seismoelectric survey successfully detected several overlapped oil layers between water aquifer and gas reservoir and our survey results are well accepted by our clients.
