DAWSON GEOPHYSICAL ANNOUNCES PURCHASE

MIDLAND, Texas, October 11, 2013/PR Newswire/ — Dawson Geophysical Company (NASDAQ:DWSN) today announced it has placed an order with Geospace Technologies for 9,000 stations of its three-channel GSX wireless recording system. The order includes sensors, batteries, trailers and accompanying system electronics. Delivery of the order is expected to occur in the Company’s first fiscal quarter of 2014 ending December 31, 2013.

Stephen Jumper, President and Chief Executive Officer said, “With the addition of these 9,000 stations of three-channel GSX and the 1,000 stations acquired in the fourth fiscal quarter of 2013, we will own 17,000 stations of multi-channel GSR/GSX wireless equipment. As previously announced, a portion of this equipment is anticipated to be deployed this winter season in Canada for several multi-channel projects, while the balance will remain in the U.S. to be deployed on a large multi-channel project in late fiscal first quarter 2014 and on subsequent microseismic applications. It is anticipated that this purchase will represent the largest item within our board-approved $35 million fiscal 2014 capital expenditure budget. Capital expenditures for fiscal 2013 were approximately $52 million.”
