Exhibit 99.1

Dawson Geophysical Company Reports First Quarter Results

MIDLAND, Texas, January 31, 2006 / PR Newswire / Dawson Geophysical Company (NASDAQ DWSN) today reported revenues of $35,493,000 for the quarter ending December 31, 2005, the Company’s first quarter of fiscal 2006, compared to $21,559,000 in the same quarter of fiscal 2005, an increase of 64.6 percent. Revenue growth was primarily the result of an increase in the number of data acquisition crews operated by the Company, the expanded capabilities of existing crews, and more favorable contract terms with Company clients as a result of continued high demand for the Company’s services. The Company operated eleven seismic data acquisition crews in the first quarter of fiscal 2006 as compared to nine crews in the first quarter of fiscal 2005.

Net income for the first quarter of fiscal 2006 was $2,300,000 compared to $1,600,000 in the same quarter of fiscal 2005, an increase of 43.7 percent, or $0.31 per share in the first quarter of fiscal 2006 versus $0.28 per share in the same quarter of fiscal 2005. The Company’s net income and earnings per share results in the first quarter of fiscal 2006 reflect a more than doubling of the Company’s depreciation charges and the issuance of an additional 1,800,000 shares in a public offering completed in March of 2005. EBITDA in the fiscal 2006 quarter was $6,412,000 compared to $3,951,000 in the prior year quarter, an increase of 62 percent.

Factors affecting the quarter results included unusually high repair costs resulting from extensive equipment damage on several crews in isolated areas of operation. The extensive equipment damage had the effect of lowering expected crew productivity. Also included in the first quarter expenses were one-time charges related to the Company’s initial compliance with Sarbanes-Oxley Section 404 and the expensing of outstanding stock options. Company President and CEO, Stephen C. Jumper stated “considering the issues affecting the quarterly results, the doubling of depreciation charges, and the increased number of shares, we are pleased to have achieved this financial result. We are pleased to have achieved these results in the December quarter which is historically our most difficult due to holiday months and shortened work days”.

As previously reported, the Company is continuing its expansion with the addition of a twelfth seismic data acquisition crew which is expected to commence operations in May of 2006 and by increasing channel capacity on its existing crews. These additions are in response to the continued high demand for the Company services as a result of continued brisk exploration and development activity by the Company’s clients. The Company believes its current order book is sufficient to maintain operations at full capacity well into calendar year 2006 with several of the crews booked into calendar year 2007. The Company’s data processing operation has also shown significant improvement during the first quarter of fiscal 2006 due to client recognition of quality performance and our expansion into the Houston market for these services.

As previously reported, the Company’s Board of Directors has increased the Company’s fiscal 2006 capital budget to $25,000,000 to cover the cost of equipping the twelfth crew and to expand and update existing crews.

In addition to the crew expansions, management is committed to improving the revenue and profitability of existing crews. The Company will continue to focus on opportunities to increase the profitability of existing crews, by obtaining more favorable contract terms with its client companies, expanding crew recording capabilities and increasing crew productivity.

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 2-D, 3-D, 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. The Company defines EBITDA as net income 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, 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 similar 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 is presented in the table following the text of this press release.

In accordance with the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995, Dawson Geophysical Company cautions that statements in this press release which are forward-looking and which provide other than historical information involve risks and uncertainties that may materially affect the Company’s actual results of operations. These risks include, but are not limited to, dependence upon energy industry spending, the volatility of oil and gas prices, weather interruptions, the ability to obtain land access rights of way and the availability of capital resources. A discussion of these and other factors, including risks and uncertainties, is set forth in the Company’s Form 10-K for the fiscal year ended September 30,

2005. Dawson Geophysical Company disclaims any intention or obligation to revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
