OF A SECOND ARAM ARIES RECORDING SYSTEM

PLANO, Texas – MAY 25, 2005 – TGC Industries, Inc.

Wayne Whitener, President and CEO of TGC Industries, commented, “We are faced with an increasing demand for Land 3-D seismic surveys, and the purchase of this new ARAM ARIES system will enable us to meet the growing needs of our clients.  With this equipment purchase, we will be in a position to equip two of our land-based acquisition crews with the ARAM ARIES systems.”

TGC, based in Plano, Texas, is a geophysical service company which primarily provides 3-D seismic services to oil and gas companies. It also maintains a geophysical gravity data bank.

This press release includes “forward-looking statements” within the meaning of section 27A of the Securities Act of 1933, as amended, and section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact included in this press release regarding the Company’s strategies and plans for growth are forward looking statements.

The forward-looking statements contained herein reflect the current views of the Company’s management, and the Company assumes no obligation to update the forward-looking statements or to update the reasons actual results could differ from those contemplated by such forward-looking statements.
