We are a leading provider of onshore seismic data to the oil and gas industry in North America. We own an extensive library of onshore and offshore geological data that we have accumulated since our inception in 1982. We believe our data library is one of the largest onshore three-dimensional (“3D”) databases available for licensing in North America and includes leading positions in oil, liquids-rich and natural gas unconventional plays as well as conventional areas. As of February 2018, we own approximately 46,900 square miles of onshore 3D data, consisting of 32,800 square miles in the United States (70%) and 14,100 square miles in Canada (30%). We have a leading market position in key geographies in the North American unconventional onshore oil and gas plays where exploration and production (“E&P”) companies have been focusing their efforts in recent years. Approximately 56% of our onshore 3D library is comprised of data located in unconventional plays. We have expanded our data library coverage into Mexico through the reprocessing of existing two-dimensional (“2D”) data which can be licensed to E&P companies. We have approximately 17,300 linear miles (9,200 net linear miles to our revenue interest) of reprocessed 2D Mexico data available for licensing, of which we have completed the processing for approximately 9,200 linear miles (4,600 net) with the remaining approximately 8,100 linear miles (4,600 net) in progress.
