TGC INDUSTRIES, INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
June 30, 2002

NOTE A -- BASIS OF PRESENTATION

The accompanying unaudited financial statements have been prepared in
accordance with the instructions to Form 10-QSB and therefore do not include
all information and footnotes necessary for a fair presentation of financial
position, results of operations and changes in financial position in
conformity with accounting principles generally accepted in the United States
of America.

NOTE B -- MANAGEMENT PRESENTATION

In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation of financial position,
results of operations, and changes in financial position have been included.
The results of the interim periods are not necessarily indicative of results
to be expected for the entire year.  For further information, refer to the
financial statements and the footnotes thereto included in the Company's
Annual Report for the year ended December 31, 2001 filed on Form 10-KSB.

NOTE C -- EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per common share are based upon the weighted average
number of shares of common stock outstanding.  Diluted earnings (loss) per
share are based upon the weighted average number of common shares outstanding
and, when dilutive, common shares issuable for stock options, warrants and
convertible securities.  The effect of preferred stock dividends on the amount
of loss available to common stockholders was $.01 and $.07 for the three
months ended June 30, 2002 and 2001, respectively, and $.03 and $.14 for the
six months ended June 30, 2002 and 2001 respectively.

Outstanding warrants that were not included in the diluted calculation
because their effect would be anti-dilutive totaled 850,000 for each of the
three and six month periods ended June 30, 2002, and 2001.  Outstanding
options that were not included in the diluted calculation because their
effect would be anti-dilutive totaled 232,100 for each of the three and six
month periods ended June 30, 2002; 260,987 and 285,997 for the three and
six month periods ended June 30, 2001, respectively.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
June 30, 2002
(Continued)

NOTE D   DIVIDENDS

Holders of the Company's Series C 8% Convertible Exchangeable Preferred Stock
("Series C Preferred Stock") will receive, when, as and if declared by the
Board of Directors of the Company, dividends at a rate of 8% per annum.  The
dividends are payable semi-annually during January and July of each year.  At
June 30, 2002, cumulative dividends of approximately $81,340 were in arrears
on the Company's Series C Preferred Stock.

Holders of the Company's 8-1/2% Senior Convertible Preferred Stock (the
"Senior Preferred Stock") will receive, when, as and if declared by the Board
of Directors of the Company, dividends at a rate of 8-1/2% per annum.  The
dividends are payable semi-annually during June and December of each year.
Dividends paid during 2000, on the Senior Preferred Stock, were paid in
additional shares of Senior Preferred Stock, in accordance with the terms of
the Statement of Resolution Establishing the Senior Preferred Stock.  In
addition, the holders elected to receive payment of the June and December
2001, and the June 2002 dividends in additional shares of Senior Preferred
Stock.  At June 30, 2002, there were no dividends in arrears on the Company's
Senior Preferred Stock.

NOTE E   CONVERSION OF SERIES C PREFERRED STOCK

At a November 30, 2001 meeting, the Company's Board of Directors voted to
reduce, on a post-reverse split basis, the conversion price of the Series C
Preferred Stock from $2.00 per share of Common Stock to $1.61 per share of
Common Stock.  In addition, the Board of Directors voted to extend the
conversion price increase date of the Series C Preferred Stock from the close
of business on December 31, 2001 until the close of business on January 31,
2002.  As a result, the conversion price was $1.61 per share of Common Stock
if converted prior to the close of business on January 31, 2002.  After
January 31, 2002, and prior to the close of business on December 31, 2002, the
conversion price per share of Common Stock shall be $3.75.  Thereafter, the
conversion price per share of Common Stock shall be $6.00.  As of January 31,
2002, a total of 1,092,250 shares of Series C Preferred Stock had been
converted into shares of Common Stock.  The 58,100 shares of Series C
Preferred Stock that were not converted as of January 31, 2002, remain
outstanding at July 31, 2002.  Had these conversions taken place at the
beginning of 2001, loss per common share would have been reduced by $0.12 and

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

RESULTS OF OPERATIONS

TGC Industries, Inc. ("TGC") was unable to maintain its first quarter 2002
profitability during the second quarter.  As a result, TGC reported a net
loss, before dividend requirements on preferred stock, of $(264,151) on
revenue of $1,654,409, for the three month period ended June 30, 2002 compared
with a net loss, before dividend requirements on preferred stock, of
$(292,945) on revenue of $2,573,480 for the same period of 2001.  Loss per
common share, on a basic and diluted basis, was $(.06) for the three month
period ended June 30, 2002, compared with a loss per common share of $(.19)
for the same period of 2001.

For the six month period ended June 30, 2002, TGC reported a net loss, before
dividend requirements on preferred stock, of $182,439 on revenue of
$4,572,269, compared with a net loss, before dividend requirements on
preferred stock, of $834,315 on revenue of $3,455,632 for the same period of
2001.  Loss per common share, on a basic and diluted basis, was $.06 for the
six month period ended June 30, 2002, compared with a loss per common share of
$.49 for the same period of 2001.

As a result of reporting a loss for the three and six month periods ended June
30, 2002 and 2001, the number of common shares used in the diluted loss per
share computation does not include any common shares issuable for stock
options, warrants or convertible securities because the effect of their
inclusion would be anti-dilutive.

TGC's seismic crew experienced adverse weather conditions during the second
quarter of 2002 and was unable to operate at sufficient production levels to
maintain profitability. Because oil and gas exploration companies continue to
curtail their domestic oil and gas exploration programs, there continues to be
excess capacity in the land-based geophysical services industry and pricing
remains very competitive. As a result, management continues to monitor
expenses and, where possible, implement cost containment programs to remain
highly competitive through this continued period of reduced industry activity.
In the opinion of management, despite the need for more U.S. energy self-
sufficiency and the industry having favorable longer-term prospects, there are
not as yet clear indications of when the geophysical industry will show
significant signs of improvement.  During 2001 there were a number of
consolidations and mergers in the geophysical industry. Management is hopeful
that with fewer seismic crews available in the marketplace that TGC will be
able to secure contracts with improved margins thereby continuing to improve
its performance in 2002.

Non-cash charges for depreciation and amortization were $772,038 in the first
six months of 2002 compared with $806,252 for the same period of 2001.

At December 31, 2001, TGC had net operating loss carryforwards of
approximately $8,100,000 available to offset future taxable income, which
expire at various dates through 2021.




                                     9

As previously reported, TGC had been notified by Nasdaq of potential delisting
of the Company's Common Stock from the Nasdaq SmallCap Market.  TGC announced
on May 20, 2002, that the Company had been notified by Nasdaq that, in
accordance with Marketplace Rule 4310(c)(8)(B), the Company's securities were
being delisted from Nasdaq SmallCap Market at the opening of Business on May
24, 2002, due to the Company's Common Stock, as previously reported, having
failed to maintain a minimum market value of publicly held shares of
$1,000,000 as required by Marketplace Rule 4310(c)(7).  Also, as previously
reported, following the delisting, the Company's securities now trade over-
the-counter on the National Association of Securities Dealers, Inc. Over-The-
Counter Bulletin Board System.


FINANCIAL CONDITION

Cash of $24,006 was provided by operations for the first six months of 2002
compared with cash provided by operations of $1,463,232 for the same period of
2001.  This decrease in cash from operations in the first six months of 2002
was primarily the result of a decrease in billings in excess of cost and
estimated earnings on uncompleted contracts and a decrease in accounts
payable, partially offset by a decrease in accounts receivable, resulting from
a decline in the level of activity during the first six months of 2002 as
compared with the last three months of 2001.  Net cash of $100,240 was used in
investing activities during the first six months of 2002 for capital
expenditures to replace certain vehicles and equipment.  Principal payments of
notes of $14,978, principal payments of capital lease obligations of $145,111
and proceeds from the issuance of debt of $29,861 resulted in net cash of
$130,228 being used in financing activities during the first six months of
2002.  TGC anticipates that available funds, together with anticipated cash
flows generated from future operations will be sufficient to meet TGC's
minimum lease and note payment obligations.

Working capital increased $454,893 to $667,249 at June 30, 2002 from the
December 31, 2001, working capital of $212,356.  The Company's current ratio
was 2.1 at June 30, 2002, compared with 1.1 at December 31, 2001.
Stockholders' equity decreased $182,439 to $2,844,344 at June 30, 2002 from
the December 31, 2001 balance of $3,026,783.   This decrease was attributable
to the net loss, before dividend requirements on preferred stock, of $182,439.

Management believes adequate sources of financing are available to enable the
Company to continue operations in the event operating revenue does not provide
sufficient cash to fund the Company's existing and ongoing obligations.
