FOR IMMEDIATE RELEASE

OYO GEOSPACE REPORTS FISCAL YEAR 2007 THIRD QUARTER RESULTS

Company Reports Third Quarter Increase in Revenues and Profits

Houston, Texas - August 3, 2007 - OYO Geospace (NASDAQ: OYOG) today announced net income of $3.7 million, or $0.60 per diluted share, on revenues of $30.5 million for its third quarter ended June 30, 2007. This compares with net income of $3.4 million, or $0.57 per diluted share, on revenues of $30.1 million in the comparable quarter last year.

For the nine months ended June 30, 2007, OYO Geospace recorded sales of $107.4 million and net income of $14.7 million, or $2.42 per diluted share. For the comparable period last year, the company recorded sales of $74.7 million and a net income of $6.3 million, or $1.06 per diluted share. The company noted that its results for the quarter and for the nine months ended June 30, 2006, benefited from the recognition of the sale of an $8.0 million seismic reservoir monitoring system to BP for installation in the North Sea - the kind of large product sale that does not necessarily recur in every subsequent quarter.

"We experienced strong worldwide demand for our seismic exploration products in the third quarter of 2007," said Gary D. Owens, OYO Geospace's Chairman, President and CEO. "Demand was strong in both our land and marine products and across most of our international markets, although we are seeing some decline in our backlog for these products. Our third quarter results were favorably impacted by the sale of a $3.0 million seismic borehole system for use in the U.S. market. We received this order late in the third quarter and we have expectations of booking several smaller borehole system orders in the fourth quarter," Owens continued.

"Our seismic borehole systems have been well-received by the marketplace and we are pleased with the increasing acceptance of this suite of reservoir imaging products. However, as we have said in the past, our sales and operating profits have varied significantly from quarter-to-quarter, and even year-to-year, and are expected to continue that trend in the future, especially when our quarterly financial results are impacted by the presence or absence of these relatively large, but somewhat erratic, shipments of seismic borehole and/or seabed data acquisition systems. At present, we do not have any large orders for these reservoir characterization products in our product backlog, although, we are optimistic about a number of on-going negotiations with customers concerning these products. We are working hard to close certain of these negotiations in the fourth quarter, but we cannot now determine what impact, if any, these potential orders may have on our fourth quarter or on future quarters. The quote-to-contract time for large permanent and retrievable seabed seismic data acquisition systems is generally quite long, and since these sales are not recognized until the products are shipped, the exact timing of any future sales can dramatically affect our quarterly results," Owens said.

"OYO-GEO Impulse International, our subsidiary in the Russian Federation, is concluding a series of transactions to sell a surplus property formerly used for manufacturing purposes. Upon conclusion of these transactions, we expect to recognize a pretax gain of approximately $2.0 million. It is possible that these transactions could be concluded totally or partially in our fiscal fourth quarter," said Owens.

"Sales of our non-seismic offshore cables and industrial products grew throughout the year. Customer backlog for these products increased, although still relatively small compared to our overall product mix. Quarterly profits from our thermal solutions products also grew this quarter, and new product introductions are scheduled for early in the next fiscal year," said Owens.

"Our move into our newly built manufacturing facility is underway. This transition phase is expected to last for several months in order to minimize any interruption to our existing production schedule. The new space and capacity will be a welcomed and needed addition to our capabilities," 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 printing industry worldwide.
