Drilling companies obtain the most accurate data and graphic representation of the geologic structure beneath the earth's surface through seismic "imaging," which is used for conducting on and offshore oil and gas explorations. Seismic imaging helps to determine the most promising "targets" for oil and gas extraction. In addition to conducting land and sea explorations, through ongoing research and development, drilling companies develop sophisticated and innovative technology to improve oil and gas extraction techniques.
