FOR IMMEDIATE RELEASE

OYO GEOSPACE REPORTS FISCAL YEAR 2007 SECOND QUARTER RESULTS

Company Reports 41% Increase in Revenues and 100% Increase in Profits

Houston, Texas - May 9, 2007 - OYO Geospace (NASDAQ: OYOG) today announced net income of $3.1 million, or $0.52 per diluted share, on revenues of $32.1 million for its second quarter ended March 31, 2007. This compares with net income of $1.6 million, or $0.26 per diluted share, on revenues of $22.7 million in the comparable quarter last year.

For the six months ended March 31, 2007, OYO Geospace recorded sales of $76.8 million and net income of $11.0 million, or $1.82 per diluted share. For the comparable period last year, the company recorded sales of $44.6 million and a net income of $2.8 million, or $0.48 per diluted share.

"Strong worldwide demand for seismic equipment resulted in record shipments of our seismic exploration products in the second quarter," said Gary D. Owens, OYO Geospace's Chairman, President and CEO. "Demand for our seismic exploration products showed gains in the quarter, and seismic exploration product demand in our Canadian and Russian markets also improved over the comparable period of the prior fiscal year. Backlog for these products remains strong," said Owens.

"We are very satisfied with these quarterly results, especially since we experienced a relatively low level of seismic reservoir product sales, which generally contain better margins. To generate this level of revenue and earnings on mostly seismic exploration products demonstrates the busy condition of our industry. We are pursing a retrievable seismic seabed cable order and several seismic borehole system orders for possible delivery this fiscal year. In addition, we are pursuing future prospects for both permanent seismic seabed systems and borehole systems for next year. We are working hard to close these transactions," Owens said.

"Our non-seismic offshore cables and industrial products continue to show healthy revenue growth and demand. Our thermal solutions product sales and operating profits were up sequentially for the quarter, although down slightly from last year's second quarter. We are continuing our initiatives to introduce new thermal solutions products and improve existing ones," said Owens.

"We expect to occupy our new building in the coming days, and then immediately begin the transition of moving existing and new equipment into this facility. This transition 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 welcome addition to our Houston-based facility," 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.
