Dawson Geophysical Co provides seismic data acquisition services mainly to providers of multi-client data libraries and directly to onshore oil and natural gas exploration and development companies in the continental U.S. and Canada. The demand for seismic services is largely influenced by drilling and completion activity, exploration budgets, and prevailing and anticipated crude oil and natural gas prices. Its data acquisition crews serve companies engaged in the exploration and development of oil and gas on land and in land-to-water transition areas. The business operates through two reportable segments, with U.S. operations generating the majority of revenue and Canada operations contributing additionally.
