The oil industry can be shaky at times, but Dawson Geophysical always looks for good vibrations. The company provides data acquisition and data processing services including the analysis of 2-D and 3-D seismic data to assess potential underground oil and gas deposits. Dawson Geophysical's customers, both major and independent oil and gas operators, use the data in exploration and development activities. The company's 3-D seismic data acquisition crews work in the lower 48 states; data processing is performed by geophysicists at the firm's computer center in Midland, Texas. In 2011 the company agreed to acquire rival seismic explorer TGC Industries for $157 million. However, the deal fell through.
