            TGC INDUSTRIES, INC. ANNOUNCES DATE
              OF ANNUAL MEETING OF SHAREHOLDERS

Plano, Texas   March 1, 2000. TGC Industries, Inc. ("TGC" or the
"Company") (Nasdaq   TGCI; TGCIP; TGCIW) announced today that its annual
meeting of shareholders will be held on Thursday, May 11, 2000.  The
record date for the Annual Meeting will be March 15, 2000.  Historically,
TGC has held its annual meeting in June; however, for efficiency and cost
considerations, the Board of Directors of TGC has determined to address
matters which were to be voted on at a special meeting of shareholders (as
reported in the Company's Form 8-K filing dated December 29, 1999, and in
a preliminary proxy statement filed February 11, 2000), at the annual
meeting and to move forward the date of the annual meeting to May 11,
2000.

The matters to be voted on at the annual meeting are as follows:

     (1)  To elect seven (7) directors to serve until the next annual meeting,
     two (2) of such directors being new nominees to the Board of
     Directors selected by WEDGE Energy Services, L.L.C. pursuant to the
     terms of the Debenture Purchase Agreement in connection with the
     purchase by WEDGE of a $2,500,000 Convertible Subordinated Debenture
     in December 1999;

     (2)  To consent, by vote of the holders of TGC's outstanding shares of
     Preferred Stock, voting as a class, to a new series of 8-1/2 % Senior
     Convertible Preferred Stock.  If the consent of the holders of 66-
     2/3% of the outstanding shares of Preferred Stock is obtained, WEDGE
     is obligated to convert its $2,500,000 Convertible Subordinated
     Debenture into such Senior Preferred Stock. Such Debenture is
     convertible at a price of $1.15 per share;

     (3)  To approve TGC's 1999 Stock Option Plan; and

     (4)  To ratify the selection of Grant Thornton, LLP as independent
     auditors.

TGC's Board of Directors will recommend that the shareholders vote in
favor of each of the above matters.

In another matter, TGC has received a favorable ruling from Nasdaq that
TGC's securities have evidenced compliance with all continued listing
criteria and that the Company's securities will continue to be listed on
the Nasdaq SmallCap Market.  As previously reported in the Company's Form
8-K filing dated December 29, 1999, the Company had a written hearing
before the Nasdaq Listing Qualifications Panel on February 3, 2000.  At
the close of business on Friday, February 25, 2000, the Company was
notified that the Nasdaq Listing Qualifications Panel had made a favorable
determination and that the Company's securities would continue to be
listed on the Nasdaq SmallCap Market.
