                TGC Industries Returns to Profitability in 2003


Plano, Texas  -- Monday, March 1, 2004 -- TGC Industries, Inc. (Nasdaq OTC BB:
TGCI) announced today that the Company returned to profitability in 2003, its
first profitable year since 1998.

The Company reported revenue of $8,468,051 for the twelve months ended
December 31, 2003, compared with revenue of $6,262,206 for the same period of
2002.  Net income, before dividend requirements on preferred stock, was
$555,165 for 2003, compared with a net loss, before dividend requirements on
preferred stock, of $(1,711,509) for 2002.  Basic earnings per common share
for 2003 was $0.05 compared with a loss per common share of $(0.37) for 2002.

As previously reported, the Company entered into the Vibroseis market in 2002,
an existing market in which the Company had not participated in the past.  The
Vibroseis market has been very beneficial for the Company.  As a result, the
Company reported a 35% increase in revenue and its first profitable year since
1998.  In addition, the Company has acquired three additional Vibroseis units
and deployed its second seismic crew.

Mr. Wayne Whitener, President and CEO of TGC Industries, Inc. stated, "We are
encouraged by the results for 2003 and management believes the Company will be
able to operate at the two-crew level for the remainder of 2004 thereby
improving 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.

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.
