TGC INDUSTRIES, INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
March 31, 1999

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 generally accepted accounting principles.

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, 1998 filed on Form 10-KSB.


NOTE C--EARNINGS PER SHARE

Basic earnings per share is based on the weighted average number of shares of
common stock outstanding.  Diluted earnings per share is based upon the weighted
average number of common shares outstanding and, when dilutive, common shares
issuable for stock options, warrants and convertible securities.  On November
5, 1998, the Board of Directors declared a one-for-three reverse stock split on
the Company's common stock.  All references to number of shares, except shares
authorized, and to per share information in the financial statements have been
adjusted to reflect the reverse stock split on a retroactive basis. 


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

RESULTS OF OPERATIONS

TGC Industries, Inc. ("TGC") reported revenues of $2,610,147 for the three
months ended March 31, 1999, compared with revenues of $4,319,329 for the same
period of 1998. Net income, before dividend requirements on preferred stock was
$274,977, compared with net income before dividend requirements on preferred
stock, of $215,523 for the same period of 1998. Income per common share, on a
diluted basis, was $.06 for the first quarter of 1999, as compared with income
of $.04 per common share for the same period of 1998.

This improved earnings performance in the first quarter of 1999 compared with
the first quarter of 1998 was principally attributable to expense reduction and
cost containment programs implemented to remain competitive during this period
of reduced industry activity and a contract termination fee received from one
of the Company's clients.

TGC's cost of services, as a percentage of revenue, were 79.3% for the first
quarter of 1999, compared to 87.4% for the same period of 1998. Selling, general
and administrative expense decreased by $47,881 in the first quarter of 1999
when compared with the same period of 1998. This decrease was attributable to
expense reductions implemented to remain competitive during this period of
reduced industry activity. Interest expense decreased by $13,229 in the first
quarter of 1999 when compared with the same period of 1998. This decrease was
primarily a result of the reducing loan balances for the purchase of geophysical
equipment.

Non-cash charges for depreciation and amortization were $492,404 in the first
quarter of 1999 compared with $414,196 for the same period of 1998.

At December 31, 1998, TGC had net operating loss carryforwards of approximately
$3,600,000 available to offset future taxable income, which expire at various
dates through 2013.

The second quarter will be a difficult period for the Company and will compare
unfavorably with the second quarter of 1998. Management is aggressively pursing
contract opportunities and believes, but there can be no assurance, that the
second half of 1999 should show some improvement.  However, it is anticipated
that the Company's revenue for 1999 will be significantly less than reported for
1998.

Management believes that the geophysical market conditions should materially
improve beginning in calendar year 2000 and seismic services should be in
greater demand enhancing the Company's performance.

FINANCIAL CONDITION

Cash of $601,551 was provided from operations for the first three months of 1999
compared with cash provided from operations of $787,919 for the same period of
1998. The funds generated in the first three months of 1999 were primarily
attributable to net earnings before non-cash depreciation and amortization
charges.  Cash used in investing activities for the first three months of 1999
was for the replacement of equipment in the amount of $9,221.  Cash used in
financing activities for the first three months of 1999 was for principal
payments of debt obligations in the amount of $698,117, and dividend payments
on preferred stock of $178,044.

Working capital deficit decreased $640,372 to $230,349 from the December 31,
1998 balance of $870,721.  The Company's current ratio was .88 to 1.0 at March
31, 1999, compared with .72 to 1.0 at December 31 1998.  Stockholders' equity
increased $322,803 from the December 31, 1998 balance of $5,127,856 to 
$5,450,659 at March 31, 1999.  This increase was primarily attributable to net
income for the three months ended March 31, 1999, of $274,977.

During the fourth quarter of 1998, the Company renewed its revolving bank line
of credit with a major bank in an amount of up to $1,000,000.  The line of
credit bears interest at prime plus 1.5%, is collateralized by equipment and
accounts receivable and requires the maintenance of certain financial ratios.

The Company began preparation for the year 2000 issues during 1996.  In late
1996, TGC upgraded and replaced its accounting software.  In addition, TGC
installed a small personal computer network.  The cost of these additions, which
are year 2000 compliant, was approximately $15,000.  TGC uses an outside source
for its payroll services and has been assured by this vendor that its software
is year 2000 compliant.  TGC will need to make a few additional hardware
upgrades in order for the total system to be year 2000 compliant.  These
upgrades will be completed by September 30, 1999, at which time the Company will
be fully year 2000 compliant.  The cost of these upgrades will be approximately
$2,000. 

At May 1, 1999, neither of the Company's two crews were employed.  However, the
Company anticipates that available funds, together with anticipated cash flows
generated from future operations (of which there is no assurance) and amounts
available under its revolving line of credit will be sufficient to meet the
Company's cash needs during 1999.

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 such 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, without limitation, the unpredictable
nature of forecasting weather, the potential for contract delay or cancellation,
and the potential for fluctuations in oil and gas prices.  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.
