Computer Mapping Artifacts 
are not there with Triangulation


(See Computer Contouring Artifacts, ESCA March 2001)

Richard Banks of Scientific Computer Applications produces a contouring program called Mapping-Contouring System (MCS). This program uses a non-gridded model, triangulation, to produce contours.

Most computer triangulation methods quit contouring at the limits of the drill hole. MCS extrapolates past the fringe data, resulting in a map that looks more like hand-contoured. A test data set run in the program does indeed show that the method honors all data points and there are no edge effects.

Following are characteristics of the MCS program:

Always honors every data point.

Makes maps which look hand contoured. Stacks and contours up to 125 surfaces simultaneously.

Determines fault vertical displacements automatically in seismic data.

Handles multiple intersection non-vertical faults among multiple surfaces.

Converts time-to-depth automatically by merging seismic and geologic data.

Creates rigorous multi-surface point-to-point cross sections.

Integrates volumes rigorously, even in fault wedge areas.

Prepares input for reservoir models and displays model results.

Generates 3-D fault leakage maps.

MCS runs on micros under DOS or Windows. For more information contact Richard B. Banks, Scientific Computer Applications, Inc. 601 S. Boulder Ave., Suite 810, Tulsa OK 74119-1328. 918-584-6197. Fax: 918-584-5120
