Global Geophysical builds its business from the ground down. It provides seismic data acquisition services to the oil and gas industry for locating potential reservoirs and studying known reserves. Global Geophysical transmits sound waves below the earth's surface to create images of the existing subsurface geology. Its integrated suite of seismic data solutions includes high-resolution RG-3D Reservoir Grade seismic data acquisition, microseismic monitoring, and seismic data processing and interpretation services. The firm's seismic crews have worked in a wide variety of terrains, including deserts, jungles, and swamps, in more than 100 countries. It emerged from Chapter 11 bankruptcy in early 2015.
