WebA method and apparatus for evaluating submarine formations, such as geological formations located generally under a body of water. Multiple hydrofoils (130), responding to moving water, hydrodynamic, or Bernoulli forces, provide controllable orientation and separation for multiple receivers (135) as they are towed (125) through water (110) in the … WebMay 1, 2013 · Achieving truly 3D high-resolution images of complex subsurface structures requires adequate spatial sampling in both the inline and crossline directions. Onshore, subject to limitations caused by surface obstructions, seismic sensors can be deployed in a square grid, resulting in equal sampling in both directions. WebSince the introduction of the seismic curvature attributes by Roberts (2001), curvature has gradually become popular with interpreters, and has found its way into most commercial software packages. Curvature is a 2D second-order derivative of time or depth structure, or a 2D first-order derivative of inline and crossline dip components. the plough henfield west sussex
