The Company reported a 68% increase in revenue to $4,783,197 for the
three months ended June 30, 2004, compared with revenue of $2,835,401
for the same period of 2003.  Net income for the second quarter of 2004
increased 138% to $520,249 before dividend requirements on preferred
stock, compared with net income of $218,515 for the same period of 2003,
before dividend requirements on preferred stock.  Diluted earnings per
common share for the second quarter of 2004 were $0.04 compared with
diluted earnings per common share of $0.03 for the same period of 2003.

For the six months ended June 30, 2004, the Company reported a 75%
increase in revenue to $7,754,069 compared with revenue of $4,437,206
for the same period of 2003.  Net income for the six month period ended

As previously reported on June 14, 2004, the Company recently deployed
its third seismic crew in response to the increased level of activity in
the domestic oil and gas market.  The Company operated with only one
seismic crew for 2003 and announced the addition of its second seismic
crew on January 14, 2004.

Mr. Wayne Whitener, President and CEO of TGC Industries, Inc. stated,
"We are very encouraged by the results for the first six months of 2004.
Even though the Company's crews experienced inclement weather during the
later part of the second quarter of 2004, management believes the
Company will be able to operate at a three-crew level for the remainder
of 2004 while continuing to improve its performance."

This report contains forward-looking statements which reflect the view
of Company's management with respect to future events.  Although
management believes that the expectations reflected in such forward-


looking statements are reasonable, it can give no assurance that
expectations will prove to have been correct.  Important factors that
could cause actual results to differ materially from such expectations
are disclosed in the Company's Securities and Exchange Commission
filings, and include, but are not limited to the dependence upon energy
industry spending for seismic services, the unpredictable nature of
forecasting weather, the potential for contract delay or cancellation,
the potential for fluctuations in oil and gas prices, and the
availability of capital resources.  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.
