             OMNI REPORTS 36% INCREASE IN SECOND QUARTER NET INCOME
                Cash Flow Increases 26% As Backlog Remains Strong

         CARENCRO, LA - AUGUST 13, 2003 - OMNI ENERGY SERVICES CORP. (NASDAQ NM:
OMNI) announced today for the quarter ended June 30, 2003, on revenues of $10.4
million OMNI reported net income of $1.5 million ($0.18 per diluted share) or a
35% increase over the reported results for the same three-month period ended
2002. For the three-month period ended June 30, 2002, OMNI previously reported
net income of $1.1 million ($0.13 per diluted share) on revenues of $9.1
million. OMNI also reported its cash flow from operations for the quarter ended
June 30, 2003 totaled $2.9 million or 26% greater than the $2.3 million reported
for the same quarter ended 2002. Further, the Company reported its backlog
remained strong at $35 million.

         "In spite of these difficult market conditions, we are extremely
pleased with the second quarter's results," said James Eckert, Chief Executive
Officer. "We continue to concentrate on streamlining our operations, improving
our efficiencies, increasing our profitability by controlling costs and
enhancing shareholder value. By combining our ever-improving operating cash flow
with the recent restructuring of our senior secured debt, we remain the dominant
provider of domestic seismic drilling services," continued Eckert. "As our
backlog tops $35 million, projects are now being booked into 2004 with continued
emphasis in our most profitable area, the transition zone. Additionally, certain
new and exciting business opportunities continue to present themselves. A new,
revitalized OMNI is now capable of capitalizing on these strategic
possibilities. Further, we remain committed to continuing the internal growth of
our aviation division and in the near future expect to supplement that internal
growth with specifically targeted external expansion," concluded Eckert.

         Headquartered in Carencro, LA, OMNI Energy offers a broad range of
integrated services to both geophysical and production companies engaged in the
acquisition of on-shore seismic data. The company provides its services through
several business units: Seismic Drilling, Helicopter Support, Permitting and

companies who have operations in both marsh, swamp, shallow water and the U.S.

called highland zones.
