Abstract: A method of generating a depositional sequence volume from seismic data is performed at a computer system having one or more processors and memory storing programs to be executed by the one or more processors. The method includes the following steps: receiving a seismic dataset, wherein the seismic dataset includes image values at a plurality of grid points of a 3-D subsurface model; identifying reflections at a first subset of the plurality of grid points and geological constraints at a second subset of the plurality of grid points of the 3-D subsurface model from processing the image values of the seismic dataset; and generating a depositional sequence volume for the 3-D subsurface model from the reflections at the first subset of grid points and the geological constraints at the second subset of grid points.

Abstract: Systems and methods for imaging waveform volumes. An image of the waveform volume may be drawn on a display device as a two-dimensional image or a three-dimensional image of a sampling probe and redrawn in real-time at interactive rates using a graphics accelerator or a graphics card. The image of the waveform volume may also include seismic-data traces that are color-filled according to texture coordinates for pixels on the display device that intersect the waveform volume.

Abstract: Solutions to the problem of reversing seismic fault movements are formulated using a model based on elasticity theory, and using finite element and boundary element methods for generating a solution. The solution involves defining slip vectors from known formations in the fault and applying a space constraint restriction to traction values on the fault surface. The method may be applied in either 2D or 3D applications. The method is computationally fast enough to allow interactive fault reversal, and permits experimentation with various unfaulting scenarios so that a geologically acceptable solution is provided.
