Abstract
The reflection point on the plane - x sin θ + z cos θ = D (1) and the corresponding midpoint of a surface spread are connected by the relation - (x´p - xc cos θ) / X cos Ф cos θ = (yp - y,) / X sin Ф = X cos Ф / 4(D-xc sin θ). (2) In equation (1), D is the depth to the reflector measured perpendicular to the reflector from the origin and θ is the dip angle. In equation (2), X is the source-to-receiver separation and Ф is the profile direction measured from the x axis. The center of the spread is at (xc, yc, 0) is a coordinate system with the z axis perpendicular to the surface. The reflection point is (x´p, yp, D) in a coordinate system with the z axis perpendicular to the reflector.
