                     MITCHAM ACQUIRES SEISMIC ASIA PACIFIC -
                      EXPANDS OPERATIONS TO SOUTHEAST ASIA



HUNTSVILLE, Texas - January 3, 2003 - Mitcham Industries, Inc. (NASDAQ: MIND)
announced today that it has acquired all of the stock of Seismic Asia Pacific
Pty Ltd ("SAP"). In a related transaction, Mitcham acquired certain
oceanographic equipment from Nautronix Asia Pacific Pte Ltd. SAP is
headquartered in Brisbane, Australia and has been an equipment supplier to the
Southeast Asia land and marine seismic, oceanographic and hydrographic
industries for more than 25 years.

"SAP's established customer base and operational infrastructure, combined with
our extensive lease pool, will provide Mitcham with a solid platform to launch a
broad scale entry with the latest technology seismic equipment into a region
that is currently undersupplied," said Billy Mitcham Jr., Mitcham's President
and CEO. "While opening a new geographic market for our seismic equipment rental
and sales business, we will also benefit from the diversification of our
business into oceanographic and hydrographic equipment supply. I am especially
pleased that Paul Duncan, SAP's General Manager and Rodger Quick, SAP's Sales
manager have agreed to remain in their positions. Our past successful business
dealings with Paul and Rodger give me a strong feeling of confidence that this
expansion will be a positive move for the company," added Mr. Mitcham.

Mitcham Industries also announced that it has signed a letter of intent to
supply a 3400 channel Sercel 408UL seismic data acquisition system for operation
in Indonesia. "We believe that this initial lease contract will lead to future
equipment lease and sales opportunities in the Southeast Asian market which we
will be better able to exploit due to our acquisition of SAP," stated Mr.
Mitcham.
