year. However, dividends declared and payable through December 1, 2000, on

payment due and payable after December 1, 2000, payment shall, subject to
certain conditions, be by cash or by issuance of additional shares of
Senior Preferred Stock at the election of the holders by written notice to
the Company.  At June 30, 2000, there were no dividends in arrears on the
Company's Senior Preferred Stock.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                CONDITION AND RESULTS OF OPERATIONS.

RESULTS OF OPERATIONS

TGC Industries, Inc. ("TGC") reported revenues of $1,798,367 and a net
loss, before dividend requirements on preferred stock, of $(1,274,759) for
the six months ended June 30, 2000, compared with revenue of $3,534,359 and
a net loss, before dividend requirements on preferred stock, of $(410,958)
for the six months ended June 30, 1999.  Loss per common share, on a
diluted basis, was $(.66) for the first six months of 2000, compared with a
loss per common share of $(.29) for 1999.

For the three month period ended June 30, 2000, TGC had revenue of
$1,439,829 and a net loss, before dividend requirements on preferred stock,
of $(588,554).  This compares with revenue of $924,212 and a net loss,
before dividend requirements on preferred stock, of $(685,935) for 1999.
Loss per common share, on a diluted basis, was $(.31) for the three month
period ended June 30, 2000, compared with a loss per common share of $(.36)
for 1999.

Although the results for the second quarter of 2000 were disappointing,
they showed a slight improvement over the first quarter of 2000.  An
increase in oil prices began in December 1999.  However, the increase in
natural gas prices just began in May 2000.  Due to these price increases
being so recent, the geophysical service industry has yet to experience an
increase in demand for its services.

June 2000 data showed that there had been an increase of just over 50% in
the number of rotary drilling rigs working in the United States.  In
addition, of the 600 plus rotary drilling rigs working in the United
States, approximately 71% are drilling for natural gas and the balance of
29% are drilling for oil.  Though there can be no assurance, management
believes TGC should see an improvement in its performance later in the year
provided the prices for oil and natural gas remain at or near their current
levels.






Non-cash charges for depreciation and amortization were $816,477 in the
first six months of 2000 compared with $975,739 for the same period of
1999.

At December 31, 1999, TGC had net operating loss carryforwards of
approximately $5,600,000 available to offset future taxable income, which
expire at various dates through 2019.

FINANCIAL CONDITION

Cash of $21,340 was provided from operations for the first six months of
2000 compared with cash provided from operations of $798,618 for the same
period of 1999.  Cash used in investing activities for the first six months
of 2000 was for the addition of equipment in the amount of $456,346.  Cash
used in financing activities for the first six months of 2000 was for
principal payments of debt obligations in the amount of $457,223.

Working capital decreased $974,529 to $117,862 from the December 31, 1999
balance of $1,092,391.  The Company's current ratio was 1.1 at June 30,
2000, compared with 2.3 at December 31, 1999.  Stockholders' equity
increased $1,315,553 from the December 31, 1999 balance of $3,493,612 to
$4,809,165 at June 30, 2000.   This increase was attributable to the
conversion in May 2000 by WEDGE Energy Services, L.L.C. ("WEDGE Energy") of
its 8-1/2% Convertible Subordinated Debenture, Series B due December 1,
2009, in the principal amount of $2,500,000 (the "Debenture") plus accrued
interest into 2,252,445 shares of Senior Preferred Stock.

The holders of the Company's outstanding Series C Preferred Stock, voted at
the Annual Meeting held May 11, 2000, to consent to a new series of Senior
Convertible Preferred Stock.  The affirmative vote of the holders of two-
thirds (2/3) of the issued and outstanding shares of Series C Preferred
Stock approved the new series of Senior Preferred Stock.  As a result of
the consent to the new series of Senior Preferred Stock by the Series C
Preferred Stock shareholders and in accordance with the terms of the
Debenture Agreement, WEDGE Energy, on May 17, 2000, converted its Debenture
into Senior Preferred Stock.  This conversion increased the equity section
of the balance sheet by $2,590,312 as additional preferred stock and
decreased long-term debt by $2,500,000 and accrued liabilities by
approximately $90,312.  In addition, 7,445 shares of Senior Preferred Stock
were issued to WEDGE Energy as payment of the June 1, 2000, dividend.  As
stated, in Note D of the Notes to the Financial Statements, Senior
Preferred Stock dividend payments through December 1, 2000 are paid by
issuance of additional shares of Senior Preferred Stock.

At August 1, 2000, one of the Company's two crews was employed with
sufficient backlog to keep it working the remainder of the year.  The
Company anticipates that available funds, together with anticipated cash
flows generated from future operations will be sufficient to meet the
Company's cash needs during 2000.
