OYO GEOSPACE REPORTS FISCAL YEAR 2008 THIRD QUARTER RESULTS

Company Delivers First Two GSR Wireless Systems

Houston, Texas - August 8, 2008 - OYO Geospace (NASDAQ: OYOG) today announced net income of $4.3 million, or $0.71 per diluted share, on revenues of $35.6 million for its quarter ended June 30, 2008. This compares with a net income of $3.7 million, or $0.60 per diluted share, on revenues of $30.5 million in the comparable quarter last year.

For the nine months ended June 30, 2008, OYO Geospace recorded sales of $104.0 million and net income of $10.9 million, or $1.78 per diluted share. For the comparable period last year the company recorded sales of $107.4 million and net income of $14.7 million, or $2.42 per diluted share. The company noted that the results for the nine months ended June 30, 2007 benefited from the revenue recognition of a $16.2 million seabed reservoir monitoring system to BP for installation in the Caspian Sea.

"Strong demand for our seismic exploration products continued throughout the third quarter. While our backlog is healthy, visibility remains limited. As anticipated, we delivered our first 1,000-channel GSR wireless data acquisition system during the third quarter to Houston Geophysical Services. Reports from the field indicate that this system is performing well, and we are very pleased with the system's initial success," said Gary D. Owens, OYO Geospace's Chairman, President and CEO.

"During the quarter, we delivered a second 1,000-channel GSR wireless data acquisition system. This system was purchased by Global Geophysical Services for use in South America on a job for Apache Corporation," Owens continued. Mr. Richard Degner, President and CEO of Global Geophysical Services, stated, "Here at Global we are very excited to be the first to deploy the GSR autonomous recording system into the international seismic market.  The nature of wireless autonomous recording systems enables us flexibility in application that greatly extends our effectiveness and productivity.  I expect utilization of autonomous seismic recording systems to grow substantially going forward.  We are grateful to Apache for choosing Global for their South American project, and we are delighted to be working together with a technology partner like OYO Geospace."

Mr. Dave Monk, Apache's Director of Geophysics commented, "Apache is pleased to use the GSR wireless system technology from OYO Geospace to advance our exploration activity in South America. OYO Geospace was also able to meet a very demanding turn around schedule and ship the new GSR system in time for our requirements."

"We are excited to have Houston Geophysical, Global and Apache as early users of our GSR wireless system. We are in active discussions with several other interested parties for possible sales of GSR wireless systems," said Owens.

Commenting on the company's reservoir characterization products, Owens continued, "During the quarter we sold a 100-level seismic borehole system to Mitcham Industries, which was our second borehole system sold to Mitcham Industries in this fiscal year. Including the sale of this 100-level borehole system, we generated revenues of $3.5 million during the quarter from seismic reservoir products and services," continued Owens.

"During June, we exhibited at the annual EAGE trade show in Rome. At this exhibition, we introduced a new shallow-water data acquisition system. This new product offering is designed for transition zone applications and was derived from our existing seismic reservoir data acquisition technology. It will be offered in both dual sensor and multi-component configurations. While this particular market is small, we still believe it is attractive to a company our size. This new system is expected to become commercially available during our 2009 fiscal year," Owens said.

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 printing industry worldwide.
