EXHIBIT 99.1

         TGC Industries Reports Strong First Quarter 2004 Profits on
                           85% Increase in Revenues


Plano, Texas  -- Monday, April 19, 2004 -- TGC Industries, Inc. (Nasdaq OTC
BB: TGCI) announced today that the Company continued to report profitable
results for the first quarter of 2004.

The Company reported revenue of $2,970,872 for the three months ended March
31, 2004, compared with revenue of $1,601,805 for the same period of 2003.
Net income, before dividend requirements on preferred stock, was $789,515
for 2004, compared with a net loss, before dividend requirements on
preferred stock, of $(43,479) for 2003.  Basic earnings per common share for
2004 was $0.13 compared with a loss per common share of $(0.02) for 2003.


As previously reported, the Company has acquired three additional Vibroseis
units and deployed its second seismic crew.  The Vibroseis market continues
to be very beneficial for the Company, with a majority of the Company's
first quarter 2004 revenues being generated from Vibroseis contracts.

Mr. Wayne Whitener, President and CEO of TGC Industries, Inc. stated, "We
were encouraged by the results for the first quarter of 2004 and management
believes the Company will be able to operate at a two-crew level for the
remainder of 2004 there by improving its performance.  Although both of the
Company's crews experienced some inclement weather during April 2004, the
Company anticipates deploying a third crew during the second quarter of 2004
because of the higher levels of demand."

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.

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.
