The use of a 3D seismic survey accurately images reflected waves by utilizing multiple points of observation in an effort to discover oil and gas deposits. A grid of geophones, used to record the vibrations caused by the vibration trucks, and seismic source impact points, locations where the trucks will be stationed, are deployed at 165-foot intervals. Noble proposes to have 16 to 20 receiver lines at one time. The result is a volume, or cube, of seismic data sampled from a range of different angles and distances. The geophones and impact points will be placed by foot, all-terrain vehicles and/or trucks.
Noble proposes for operations to take place during the fall to ensure minimum disturbance to the land and resources. The seismic survey will take approximately 60 days to complete once operations begin.
