GM-SYS® is a program for calculating the gravity and
magnetic response from a geologic model.
GM-SYS provides an easy-to-use interface for interactively creating and
manipulating models to fit observed gravity and/or magnetic data. Rapid
calculation of the gravity and magnetic response from 2-D or optional 2¾-D model
speeds the interpretation process and allows you to quickly test alternative
solutions. Calculated responses change instantaneously as you change the model.
Models and data can
be imported from ASCII files, by hand, or extracted interactively from an
OASIS montaj™ database.
Six Options are available:
Enhanced Forward Modeling capability is attained with the 2¾-D
modeling option. This option allows blocks to be truncated in the ± Y
direction and asymmetrically positioned about the line of the profile.
The GM-SYS Inversion/Optimization option permits inverse
modeling of gravity and/or magnetic data to obtain the optimal fit of the
geologic model to your data.
Calculate any or all of the six gradient tensor components of
the gravity field and the vertical gradient of the total magnetic field.
The Seismic Bitmap option permits integration of seismic data
depth-scaled information (e.g. scanned cross-sections) into the odeling
Extended Model Size
Licensers of the Professional Edition can extend their
modeling capability by up to 750 surfaces and 300 blocks with the Extended
Model Size option.
Licensers of the Professional Edition can extend the number of
gravity and magnetic points to 16,000.
