EXHIBIT 99.1

               TGC Industries Announces Deployment
                      Of Third Seismic Crew

Plano, Texas  -- Monday, June 14, 2004 -- TGC Industries, Inc. (Nasdaq OTC
BB: TGCI) announced today that the Company has continued to experience an
increase in demand for its oil and gas exploration 3-D seismic services.
The Company has secured a sufficient number of contracts to deploy a third
seismic crew.  The Company operated with only one seismic crew for 2003 and
recently announced the addition of its second seismic crew on January 14,
2004.

Mr. Wayne Whitener, President and CEO of TGC Industries, Inc. stated, "Oil
and gas exploration companies have continued to increase the level of
activity in their domestic oil and gas exploration programs.  The services
provided by the limited number of domestic 3-D seismic crews are in strong
demand because of this increase in activity.  Though there can be no
assurance, should this increased level of activity in the industry continue
during the remainder of 2004, management believes the Company will be able
to operate at the three-crew level for the remainder of 2004."

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.
