A software tool
for the analysis of fault and fracture population statistics, including
the option to plot more that one dataset, over differing scale ranges,
for example seismic, core or outcrop scale. The software is supplied
with a comprehensive manual which documents best practice in the
application of distribution modelling.

|
 |
| Log:log cumulative
frequency plot of a fault length distribution. A finite range correction
(Pickering et al. 1995) is applied to correct for undersampling of large
fractures |
|
|
|
Example applications include:
|
- Extrapolating observed seismic
scale fault densities to a core scale for estimation of the fracture
density within a reservoir, allowing a better assessment of the
risk of compartmentalisation
- Assessing the mapped fault distribution
characteristics in terms of the underlying power-law distribution
displayed by natural fault sets
- Plots to test a population's distribution
characteristics, estimation of D-value and calculation of statistical
errors

Log:log
number in interval plot of a fault length distribution.

|
DMT includes:
|
- Cumulative frequency plots to
test a population's distribution characteristics
- Line-fitting algorithms and estimation
of D-values, including correction procedures and alternative graphing
techniques
- Calculation of statistical errors
on D-value estimates at the 68% and 95% confidence levels
- Normalisation procedure to allow
core and seismic data scaling relationships to be assessed from
one graph
- Comprehensive user manual
- Explains how to use the software
in detail
- Gives an extensive up-to-date
review of the advances in population analysis
- Highlights sources of error, pitfalls
in analysis and how they can be avoided!
