                         NOTES TO FINANCIAL STATEMENTS

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

These financial statements have been prepared without audit as permitted by the
rules  and  regulations  of  the  Securities and Exchange Commission.   Certain
information  and  footnote  disclosures  normally  included  in  the  financial
statements  have  been  condensed   or  omitted  pursuant  to  such  rules  and
regulations.   However, the management  of  OMNI  Energy  Services  Corp.  (the
"Company") believes that this information is fairly presented.  These unaudited
condensed consolidated financial statements and notes thereto should be read in
conjunction with  the  financial  statements  contained in the Company's Annual
Report  on Form 10-K for the year ended December  31,  1997  and  "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

Certain  reclassifications  have  been  made  to  the  prior  year's  financial
statements  in  order to conform with the classifications adopted for reporting
in fiscal 1998.

In  the  opinion  of  management,  the   accompanying   unaudited  consolidated
financial statements  contain  all  adjustments,  consisting  of  only  normal,
recurring  adjustments,  necessary to fairly present the financial results  for
the interim periods presented.

IMPAIRMENT OF LONG-LIVED ASSETS

During  1995,  the  Company  adopted  the  Statement  of  Financial  Accounting
Standards (SFAS) No. 121, "Accounting  for  the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of."   Under  the  provisions  of this
statement,  the  Company  has  evaluated  its  long-lived  assets for financial
impairment,  and  will  continue  to  evaluate  them  as events or  changes  in
circumstances indicate that the carrying amount of such assets may not be fully
recoverable.

The Company evaluates the recoverability of long-lived assets not held for sale
by  measuring  the  carrying  amount  of  the  assets  against   the  estimated
undiscounted  future  cash  flows  associated  with  them.   At  the time  such
evaluations  indicate that the future undiscounted cash flows of certain  long-
lived assets are not sufficient to cover the carrying value of such assets, the
assets are adjusted  to  their  fair values.  Based on these evaluations, there
have been no adjustments to the carrying value of long-lived assets in previous
periods.

During the third quarter of 1998,  the  Company evaluated the recoverability of
certain long-lived assets by comparing the assets  carrying  amounts with their
fair value less cost to sell.  In September 1998, the Company recorded a charge
of $3.1 million as a result of its decision to write-down and  write-off  these
assets (see Note 5).

SEASONALITY AND WEATHER RISKS

Results of operations for interim periods are not necessarily indicative of the
operating results that may be expected for the full fiscal year.  The Company's
operations  are  subject  to  seasonal  variations  in  weather  conditions and
daylight hours. Since the Company's activities take place outdoors, on average,
fewer  hours  are  worked  per  day  and  fewer holes are generally drilled  or
surveyed per day in winter months than in summer  months, due to an increase in
rainy,  foggy,  and  cold  conditions  and  a  decrease  in   daylight   hours.
Furthermore,  demand  for  seismic  data  acquisition  activity  by oil and gas
companies  in the first quarter is generally lower than at other times  of  the
year.  As a  result,  the  Company's  revenue and gross profit during the first
quarter of each year are typically low as compared to the other quarters.

USE OF ESTIMATES

The preparation of financial statements  in  conformity with generally accepted
accounting  principles requires management to make  estimates  and  assumptions
that affect the  reported  amounts of assets and liabilities and the disclosure
of contingent assets and liabilities  at  the  date of the financial statements
and the reported amounts of revenue and expenses  during  the reporting period.
Actual results could differ from those estimates.

NOTE 2.  EARNINGS PER SHARE

In  1997, the Company adopted Statement of Financial Accounting  Standards  No.
128,  "Earnings  Per  Share,"  which  simplifies  the  standards required under
existing  accounting rules for computing earnings per share  and  replaces  the
presentation of primary earnings per share and fully diluted earnings per share
with basic  earnings  per  share  ("basic  EPS") and diluted earnings per share
("diluted EPS"), respectively.  Basic EPS excludes  dilution  and is determined
by  dividing  income  available to common stockholders by the weighted  average
number of shares of common  stock  outstanding  during the period.  Diluted EPS
reflects the potential dilution that could occur if options and other contracts
to issue shares of common stock were exercised or  converted into common stock.
Dilutive common equivalent shares for the three and  nine  month  periods ended
September  30,  1998  are  15,946,428  and,  16,018,590,  respectively, and for
three and  nine  month  periods  ended September 30, 1997  are  11,906,605  and
11,125,981, respectively, all attributable to stock options.

NOTE 3.  LONG-TERM DEBT

On  January  20,  1998,  the Company restructured its credit arrangements  with
Hibernia  National  Bank.   Under   the   restructured  facility  (the  "Credit
Facility"), the Company refinanced an $11.0  million  loan,  obtained  a  $10.0
million  revolving  line of credit to finance working capital requirements, and
obtained a $9.0 million  line  of  credit  to  finance capital expenditures and
acquisitions.  As of September 30, 1998, the Company  had  approximately  $24.6
million outstanding under the Credit Facility.  The Credit Facility has a final
maturity  of  January  20, 2000, and bears interest at LIBOR plus an applicable
margin, ranging from 1.25% to 2.25% (6.91% at September 30, 1998).


NOTE 4.  ACQUISITIONS

In  April 1998, the Company  acquired  Eagle  Surveys  International,  Inc.,  a
seismic survey support company, headquartered in Houston, Texas.  The aggregate
purchase  price  was $1.8 million consisting of $1.1 million in cash and 53,039
shares of common stock.

In April 1998, the  Company  acquired  the  assets of Coastal Turbines, Inc., a
helicopter  support  company,  based in Lafayette,  Louisiana.   The  aggregate
purchase price was approximately  $1.2  million  consisting  of $1.1 million in
cash and 4,546 shares of common stock.

In  May  1998,  the  Company  acquired  Hamilton Drill Tech, Inc., a  specialty
seismic drilling support company, headquartered  in Canada.  The purchase price
was approximately $0.9 million in cash.

In  July  1998,  OMNI  International  Energy  Services,  Ltd.  (a  wholly-owned
subsidiary) entered into a joint venture with Edwin  Waldman  Attie of Bolivia.
The  newly formed joint venture company, OMNI International Energy  Services  -
South  America,  Ltd. provides seismic line cutting and survey support services
in South America.  The aggregate investment  was  approximately  $6.5  million,
consisting of approximately $2.6 million in cash, which was paid in the  fourth
quarter, $2.0 million in equipment and  155,947  shares of  common  stock.   In
consolidation,  the Company owns an 85% interest in the joint venture.

These acquisitions were accounted for using the purchase  method of accounting.
The  excess  of cost over the estimated fair value of the net  assets  acquired
resulted in goodwill  of  approximately $4.6 million.  The operating results of
each  of  the  acquired  companies  have  been  included  in  the  consolidated
statements of income from the date of acquisition.  The pro forma effect of the
acquisitions as though they  occurred  as  of  the  beginning  of  each  period
presented is not material.

In  July  1997,  the  Company  acquired  substantially  all  of  the assets and
liabilities  of  American  Aviation  Incorporated  ("American  Aviation")   for
approximately  $7.9 million in cash and stock and assumed debt of approximately
$6.7 million. The following summarized unaudited income statement data reflects
the  Company's results  of   operations as if the American Aviation transaction
had taken place on January 1, 1997:



                            UNAUDITED PRO FORMA RESULTS
                         NINE MONTHS ENDED SEPTEMBER 30, 1997
                  (Thousands of dollars, except per share amount)

Revenue                             $ 36,335

Net income                          $ 2,948

Basic income per share              $  0.27


NOTE 5.  ASSET IMPAIRMENT AND OTHER CHARGES

In response to recent market conditions and the resultant  decline  in  certain
asset utilization of the Company's equipment, the Company evaluated certain  of
its assets for realizability.  The related asset impairment charges relate to a
$1.8 million provision for fixed assets, primarily nine drilling   units  which
have   become  impaired,  due to recent  changes  in  market conditions; a $1.3
million write-off of an asset held for sale which has become  impaired  due  to
recent  price   declines;  and  a  $0.6  million  additional    provision   for
uncollectible accounts receivable.

In addition, in response to anticipated future market conditions, the Company's
senior management and its Board of Directors approved a plan to reduce  furture
operating costs and improve operating efficiencies.  The plan involves  several
factors including the restructuring of senior management and the relocation  of
certain of its operational facilities.  Accordingly, the company  has  recorded
an accrual of severance and lease exit costs of $0.3 million.

The $0.6 million provision for uncollectible accounts receivable is reported in
general and administrative expenses and the remaining  charges  are reported as
asset impairment and other charges in the accompanying consolidated  Statements
of Income.

NOTE 6.  RECENT PRONOUNCEMENTS

In  June  1998,  the  Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments  and  Hedging  Activities,"  which  is  effective  for fiscal years
beginning after June 15, 1999.  Management believes the implementation  of this
statement  will  not  have  a  material  effect on its results of operations or
financial statement disclosures.
