3D Geological Modeling |
|
LYNX Geological modeling is based on proven surface and volume modeling
technology allowing 3D interpretation and
modeling of complex geological structures. The geological modeling functions
are fully integrated with LYNX hole data, data
analysis, geostatistical estimation and engineering applications.
3D interactive geological interpretation
|
|
- Background displays of any combination of data structures in a wide range
of display formats
- Interactive 3D interpretation of volume boundaries into complex irregular
shapes
- Interactive geological sectioning at any view plane orientation through
defined geological units.
Surface- based modeling tools provide an alternative modeling option to
interactive interpretation. They allow rapid generation of geological models
from structural and stratigraphic surface information. Surface-based techniques
are particularly appropriate to relatively simple geological conditions,
such as layered stratigraphy. |
|
3D visualization and interpretation
|
|
Proven volume modeling technology and interactive view plane manipulation
capabilities allow complex geological conditions to be interpreted using
methods that are familiar to all geologists. Interpretation progresses
from sections, to intersecting fence sections, to a fill 3D interpretation
of geological volumes. Any degree of subsurface complexity may be modeled.
Interpretation may be made at any orientation on 2D sections or in a full
3D modeling environment. |

3D Geostatistics and Estimation |
|
The LYNX geostatistical analysis and estimation applications are a windows
based implementation of GSLIB 3D geostatistics.
LYNX also includes Direct Volume Estimation for the estimation of complex
volumes, eliminating the need for a
3D grid and grid sub-blocking.
Data Functions and Compositing
|
|
- Arithmetic, log or trip functions of project variables
- Logical functions of characteristics and/or variables
- Compositing of hole data samples

Geostatistical Analysis
|
|

including 3D trend surfaces.

combination.
|
|
Estimation capabilities include a range of kriging options and semi-variogram
model types, and all necessary facilities for dealing with variable sample
density, anisotropy, non-normal distributions and underlying spatial trends.
These ensure that the estimation process can deal with cases of complex
spatial variability.
3D grid manipulation capabilities provide a means of combining estimated
variable values using complex arithmetic or logical functions. 3D grid
import / export facilities provide the options of using external prediction
facilities where appropriate, and of exporting grid data structures for
external analysis.
Direct volume estimation provides a unique method for estimating variables
directly into complex volumes eliminating the need for a 3D grids or sub-blocking.
Hole data functions allow generation of variable and characteristic functions
that are tailored to the project.
Sample compositing for regularization of samples in hole data structures,
including the honouring of geological intersections. |
Statistical Analysis
|
|
- Univariate statistics including mean, sample size, standard error, histogram,
probability, correlation, etc.
|
|
Geostatistical Estimation
|
|
- 3D kriging estimation of variable values using normal or universal kriging and point or volume
kriging algorithms.
- 3D inverse distance interpolation of variables for instances when kriging prediction is inappropriate.
- Geological control of sample and grid cell selection for prediction of geologically influenced
variables.
- Spatial data control of sample selection by octant search.
- 3D grid manipulation allows combination of estimated values using a wide variety of functions.
- Direct volume estimation for kriging into irregular volumes.
|
The geostatistical analysis toolkit includes facilities for identifying
and isolating geological influences, directional influences due to anisotropy,
and underlying data trends. A range of data transformation options extends
the analytical capabilities to deal with cases of non-normal value distribution.
All facilities and results are accessible through an interactive, point-and-click
graphics interface. |
