DAWSON GEOPHYSICAL REPORTS
FIRST QUARTER RESULTS

Average Channel Count Per Crew
Continues to Grow

MIDLAND, Texas, February 2, 2011/PR Newswire/ — Dawson Geophysical Company (NASDAQ DWSN) today reported revenues of $72,653,000 for the quarter ended December 31, 2010, the Company’s first quarter of fiscal 2011, compared to $36,330,000 for the same quarter in fiscal 2010, an increase of 100 percent. Net loss for the first quarter of fiscal 2011 was $1,667,000 compared to net loss of $4,216,000 in the same quarter of fiscal 2010. Loss per share for the first quarter of fiscal 2011 was $0.21 compared to loss per share of $0.54 for the first quarter of fiscal 2010. EBITDA for the first quarter of fiscal 2011 was $4,899,000 compared to a loss of $211,000 in the same quarter of fiscal 2010.

The revenue increase in the quarter was primarily the result of the previously announced redeployment of three data acquisition crews during fiscal 2010, increased channel count per crew and improved utilization rates on existing crews. Revenues in the quarter continued to include unusually high third-party charges related to the use of helicopter support services, specialized survey technologies and dynamite energy sources. The sustained level of these charges is driven by the Company’s continued operations in areas with limited access such as the Appalachian Basin, East Texas, and Arkansas. The Company is reimbursed for these expenses by its clients.

Stephen Jumper, President and CEO of Dawson Geophysical Company, said, “The first quarter of fiscal 2011 results were remarkably improved from the same quarter of fiscal 2010. Increased exploration activity across oil and liquid-rich basins, combined with improving operational efficiencies and crew utilization rates drove much of our first quarter improvement. Although intermittent weather and permit issues along with the normal first quarter issues of shorter days and the holiday season negatively impacted our first quarter results, we are seeing a strong increase in activity from the prior year.”

First Quarter 2011 Highlights

	•		Increased activity across oil and liquid-rich basins with continued activity in large natural gas shale basins such as the Bakken, Niobrara, Eagle Ford, Marcellus, Haynesville, Fayetteville and Barnett;
	•		Operated twelve data acquisition crews;
	•		Increased channel count per crew;
	•		Continued strengthening in order book;
	•		Increase in requests for proposals;
	•		Took delivery of ten new vibrator energy source units;
	•		Took delivery of additional 2,000 four-channel OYO GSR units complete with 3-C geophones and began taking delivery of 10,000 channels of OYO GSR single-channel units completed in January

Jumper continued, “Demand for our services continues to grow. An increasing number of our projects are requiring higher channel counts in an effort to obtain higher resolution images. While we remain in a competitive pricing environment and weather conditions in the early part of the second quarter of fiscal 2011 have been difficult, this increased demand is helping to increase short-term utilization rates and allow us to take advantage of increased crew efficiencies and productivity. Although our clients may cancel their service contracts on short notice, we believe our current order book reflects commitment levels sufficient to maintain operations for twelve crews through the middle of calendar 2011.”

As previously announced, the Company’s Board of Directors has approved a $35,000,000 capital budget for fiscal 2011 which has been used in part to purchase the additional 2,000 stations of OYO GSR four-channel units with 3-C geophones, 10,000 OYO GSR single-channel units and ten vibrator energy source units, and the remainder will be used to meet necessary maintenance requirements during fiscal 2011. The addition of the four-channel OYO GSR recording equipment will allow the Company to record 12,000 channels of multi-component data or up to 16,000 channels of conventional seismic data either as a stand alone system or as added channel count and increases flexibility for the Company’s existing ARAM recording systems. As of February 1, 2011, the Company owns approximately 26,000 OYO GSR channels.

Jumper concluded, “We are very encouraged as we enter fiscal 2011. Exploration activity is on the rise. Many of our highly valued clients are seeking to further lower their finding and development costs and gain access to increased subsurface resolution. We believe that seismic data continues to be the best technology to achieve these goals. Our experienced professionals and our debt-free balance sheet with $75 million of working capital continue to put us in a position to meet our clients’ demands.”

Dawson Geophysical Company is the leading provider of U.S. onshore seismic data acquisition services as measured by the number of active data acquisition crews. Founded in 1952, Dawson acquires and processes 2D, 3D and multi-component seismic data solely for its clients, ranging from major oil and gas companies to independent oil and gas operators as well as providers of multi-client data libraries.

This press release contains information about the Company’s EBITDA, a non-GAAP financial measure as defined by Regulation G promulgated by the U.S. Securities and Exchange Commission. The Company defines EBITDA as net income (loss) plus interest expense, income taxes, depreciation and amortization expense. The Company uses EBITDA as a supplemental financial measure to assess:

	•		the financial performance of its assets without regard to financing methods, capital structures, taxes or historical cost basis;
	•		its liquidity and operating performance over time in relation to other companies that own similar assets and that the Company believes calculate EBITDA in a similar manner; and
	•		the ability of the Company’s assets to generate cash sufficient for the Company to pay potential interest costs.

The Company also understands that such data are used by investors to assess the Company’s performance. However, the term EBITDA is not defined under generally accepted accounting principles, and EBITDA is not a measure of operating income, operating performance or liquidity presented in accordance with generally accepted accounting principles. When assessing the Company’s operating performance or liquidity, investors and others should not consider this data in isolation or as a substitute for net income (loss), cash flow from operating activities or other cash flow data calculated in accordance with generally accepted accounting principles. In addition, the Company’s EBITDA may not be comparable to EBITDA or similarly titled measures utilized by other companies since such other companies may not calculate EBITDA in the same manner as the Company. Further, the results presented by EBITDA cannot be achieved without incurring the costs that the measure excludes: interest, taxes, depreciation and amortization. A reconciliation of the Company’s EBITDA to its net income (loss) is presented in the table following the text of this press release.
