The group's principal activity is to provide geophysical services. The services are provided through conducting seismic surveys and to a lesser extent through sales of gravity information from the company's data bank to companies engaged in the exploration for oil and gas in the United States. The survey is done using seismic, gravity or magnetic instruments and provides data about the properties of earth, which is then interpreted by various means to obtain useful information for oil and gas companies. The two survey techniques used by the company in acquiring geophysical data are seismic and 3 gravity. Land seismic surveys are the group's principal method of data acquisition and are the most widely used geophysical technique.
