OYO GEOSPACE REPORTS FISCAL 2006 SECOND QUARTER RESULTS

Company Announces Expansion of Houston Manufacturing Facility

Houston, Texas -- May 5, 2006 -- OYO Geospace (NASDAQ: OYOG) today announced net income of $1.6 million, or $0.26 per diluted share, on revenues of $22.7 million for its second quarter ended March 31, 2006. This compares with net income of $1.5 million, or $0.27 per diluted share, on revenues of $21.3 million in the comparable quarter last year.

For the six months ended March 31, 2006, OYO Geospace recorded sales of $44.6 million and net income of $2.8 million, or $0.48 per diluted share. For the comparable period last year, the company recorded sales of $36.6 million and a net income of $1.9 million, or $0.33 per diluted share.

"Results for the quarter were fueled by the continued high demand worldwide for seismic services which stimulates demand for our products. In Canada, a warmer than normal winter season slowed the usually strong demand for our seismic equipment rentals. However, strong demand in Canada for sales of seismic equipment helped to offset the decline in rental revenues," said Gary Owens, the Company's President and Chief Executive Officer.

"Sales of our seismic reservoir products were relatively low this quarter but, as previously announced, we recently received three contracts totaling almost $30 million for seismic reservoir monitoring systems. The first contract is for a $7.6 million permanent seabed system ordered by BP for use in the North Sea. This system has now been delivered to BP and installation is expected to begin soon. Revenues from this contract will be recognized upon completion of the system's installation, which is presently scheduled for June or July of 2006. The second contract is a $7.0 million retrievable seabed system for the Bureau of Geophysical Prospecting (BGP), a Chinese seismic contractor. Upon delivery and acceptance of the system by BGP, which is currently also scheduled for June or July of 2006, the company expects to recognize $6.3 million of the contract revenues. Additional revenues of $0.7 million will be recognized after the system has successfully operated for a specified time period, which we expect to occur in fiscal year 2007. The third contract is a $14.2 million seabed system ordered by BP for reservoir monitoring operations in the Azerbaijan sector in the Caspian Sea. Revenues are expected to be recognized after successful installation of the system, which is presently scheduled to occur at the end of the 2006 calendar year, which falls into the company's first quarter of fiscal year 2007. Production and delivery of all three contracts are currently on schedule. Our factory and equipment utilization for this product line is currently running at maximum capacity. We are excited about the impact of this new technology on our company as well as its impact on our customer's ability to increase the efficiency of energy production" added Owens.

"Sales of our non-seismic offshore cable and industrial sensor products continued to grow in the quarter. Revenues from these products for the three months and six months ended March 31, 2006 grew 116% and 56%, respectively, from the comparable periods of the prior fiscal year. However, further growth for our offshore cable products is constrained by capacity limitations at the moment," continued Owens.

"Sales from our thermal solutions products were very good this quarter, reaching a six-year quarterly high. We are beginning to see improvements and consistency in our thermal printhead production operation, allowing us to meet pent-up customer demand," said Owens.

"As mentioned above, portions of our Houston manufacturing facility are running at or near full capacity. Some manufacturing departments are operational 24 hours a day, seven days a week causing us to outsource certain operations due to capacity limitations. Our cabling, machining and molding shops are especially space challenged. Backlog for the Houston factory remains high and prospects for future business also look bright. To alleviate our capacity constraints, the Board of Directors recently approved a $10.0 million expansion of our manufacturing space by about 50% and to add the appropriate manufacturing machinery and equipment to meet expected future demand. This facility expansion will be located on surplus land at our Pinemont facility in Houston. We plan to break ground for the expansion immediately and to be able to use the new facility near the end of this calendar year. The facility expansion is expected to be financed with a long-term mortgage, and any machinery and equipment will be financed from our internal cash flow and/or from our line of credit. This investment marks a bold initiative by the company, preparing it for further growth in the various markets it serves," continued Owens.

OYO Geospace designs and manufactures instruments and equipment used by the oil and gas industry in the acquisition and processing of seismic data as well as in reservoir characterization and monitoring activities. The company also designs and manufactures equipment and film for the thermal solutions industry worldwide.
