f Seismic Coring

Seismic coring is a 3-D land seismic reflection acquisition technique that has an arrangement of source and receivers which differs from the currently used acquisition techniques. This unique arrangement of the source and receivers allows better and easier interpretation of the subsurface structures. The layout of this technique differs from previous 3-D acquisition techniques, one source is used and is placed in the center of the array, the geophones are then placed on successive circles and the radius of each circle increases gradually from the center till the last receiver line with multiples of the first of the first circle. The array consists of straight receiver lines arranged in a radial manner from the center of the layout. The distance between two successive geophones on the same receiver line is constant while the angular distance between two receiver lines is variable. The final data acquired from this geophone arrangement would represent a cylindrical section of the subsurface ground.
