           OMNI COMPLETES $65 MILLION IN NEW SENIOR CREDIT FACILITIES

     Proceeds Used to Re-Finance Long-Term Debt and Provide Working Capital

      CARENCRO, LA - MAY 18, 2005 - OMNI ENERGY SERVICES CORP. (NASDAQ NM: OMNI)
announced today it has completed $65 million of Senior Credit Facilities with a
syndicate of lenders including GE Commercial Finance Energy Financial Services
("EFS") and Webster Business Credit Corporation ("Webster"). The proceeds will
be used to re-finance certain long-term debt and provide working capital.

      The Senior Credit Facilities include a $50 million equipment Term A Loan
and a $15 million working capital revolver. Borrowing under the asset based,
Term A Loan is determined by advance rates on the agreed upon value of the
Company's unencumbered aviation, seismic drilling and environmental equipment.
The Term A Loan matures in 60 months with level amortization over 120 months.
Principal payments will be made quarterly with interest accruing at an initial
rate of 30-day LIBOR plus 6.5% and also paid quarterly, in arrears.

      The Company also announced it has increased its Working Capital Revolver
to $15 million from its current level of $12 million. Availability under the
Working Capital Revolver is based upon the Company's level of eligible accounts
receivable and inventories of spare parts. The Working Capital Revolver matures
in 60 months and will initially accrue interest at a rate of prime plus 2.5%, or
at the Company's option LIBOR plus 5%, payable monthly in arrears.

      On the new Senior Credit Facilities, James C. Eckert, OMNI's Chief
Executive Officer commented, "These new credit facilities are an exciting
component of our business model for the continued expansion and growth of OMNI
without diluting shareholder value. The structure of the new Senior Credit
Facilities postures OMNI to continue aggressively pursuing strategic
acquisitions. We have always enjoyed our relationship with an excellent
financial institution such as Webster. Now, our transaction with Energy
Financial Services establishes a relationship with a major financial services
provider that is very active in the energy and oilfield services sectors.
Management remains confident in its long-range business model to establish OMNI
as a leading provider of an integrated range of services to the oil and gas
industry," continued Eckert.
