As I mention throughout the review, Oasis montaj shines both for processing and visualizing data while working with gravimetric data . It's 2D and 3D geologic basement models can be really detailed and, depending on the interpreter, can be really accurate. Plus, they can serve as an excellent tool for oil exploration when integrating them with seismic and well log information. Since it is an expensive software, small companies or universities with low budgets would be better using other programming tools.
The Paradigm geologic and petrophysical interpretation software suite offers a complete package for integrated projects where a team starts from offset well data and leads all the way to mapping of horizons, properties and reservoir models. Geolog, the petrophysical module, is very powerful and versatile. Although they offer separate add-ons, for smaller projects where the petrophysical interpretation is done by a third-party, even the minimum package might be overkill.
Geological basement modeling both in 2D and in 3D.
Processing and quality control on geophysical, geochemical and geological data.
Data both in the database or uploaded is provided through a spreadsheet and an integrated profile display window, so it is extremely easy to visualize the information or modify it.
Geolog is extremely robust and powerful in handling large volumes of logs per well and a large number of wells, which is an asset for basin-scale projects.
Geolog is very flexible in terms of customizing log layout presentations and calculating anything via mathematical or logical expressions.
Epos display of fluid production data is very useful in cross-analyzing maturity and organic content versus hydrocarbons produced.
Geolog could use a LAS batch loading graphical interface that doesn't require the use of prompt commands.
Geolog's geologic intervals display has improved in the last versions, but it's still cumbersome to set up and maintain (i.e. adding new intervals, changing stratigraphy).
SKUA-Paradigm should support geographic coordinates in order to avoid the workaround of creating pseudo-coordinates across UTM zone boundaries.
Regarding the petrophysical modules, I have used other petrophysical software packages, and Paradigm is superior in data handling, visualization, flexibility, and batch calculations. Regarding the mapping and modeling, Paradigm is on par with other software I used on the same scale. SKUA-Gocad has some advantages over its main competitor, in terms of data manipulation, but the inability to handle geographic coordinates has a negative impact on my work efficiency.
Using oasis montaj allowed to work on several projects for gravimetric data interpretation that represented a great profit for our business.
Oasis was an excellent learning tool that brought profit to our university since all the work we did were actual problems that when solved generated profit for the faculty
Paradigm Geolog has allowed us to handle the vast quantities of well log data in order to achieve our research goals and deliver the results to the sponsoring companies.
Paradigm Epos and SKUA-GOCAD have made possible to map the results of our petrophysical analysis on a basin-wide scale encompassing two provinces, without which our research deliverables would not have been possible.
