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
