What's new? : Major Software Releases Log History
Following down is a list of some stable versions released. Please make sure
you always have the latest version installed.
-
2021 January 04.
Build version ID = 1EC623
GeolOil 2021 Edition is released.
This is our major release since our GLS Scripting language was launched in 2018.
GeolOil 2021 main features are:
-
A fully editable alias system. It incorporates a fuzzy logic engine that automatically pairs
curve mnemonics with aliases. It has a high matching rate.
-
A display template system, with export and import capabilities for all tracks with its curves, colors and fillings.
-
An automatic fuzzy logic plotting engine for LAS files. As soon as a new LAS file is open, GeolOil analyzes it and detects
its curve mnemonics, pairs them with aliases, and produces a tentative log plot with tracks and curves:

2020 October 25.
Build version ID = 3BC172
A new, widely usable minimal mineral solver that runs only with Vshale and RHOM was added.
After VSH is estimated, and the matrix density RHOM is estimated from the neutron to density contrast,
this simple maximum entropy solver finds the volumes of clay, silt, quartz, calcite, and dolomite.
Since curves for neutron porosity and bulk density are quite common, this mineral solver allows
to explore and gives a clue of the dominant minerals in the matrix.
-
2020 October 13.
Build version ID = 038A98
The SW water saturation ratio equation, now includes a correction for VSH shaliness.
As expected, it yields smaller water saturations than Archie when VSH > 0.
One more time, Archie over-estimates the amount of water, overlooking potential pay candidates.
-
2020 October 12.
Build version ID = B38EBE
Two new Vshale equations were added to the Functions Work-flow: The generalized Stieber equation,
and its self adjusting C continuous curve parameter to calibrate VSH against an unbiased
reference, like VSH from Neutron-Density.
-
2020 October 01.
Build version ID =08220C
GeolOil is migrated to
Java-15,
while keeping legacy compatibility
with Java-8/x64-bits, Java-9, Java-10, Java-11, Java-12, Java-13, and Java-14.
-
2020 August 27.
Build version ID = 9343A3
Improved Button-SpaceBar focus policy for a better user experience.
-
2020 May 16.
Build version ID = 3B0A18
Log plots are now displayed by default with a double scale: a regular MD scale, and a TVD-SS, TVD, & INC
navigation scale in the first track.
This is particularly useful for tilted and horizontal wells.
The horizontal well below has an inclination of more than 90° (it is navigating upwards).
Notice how TVD decreases while MD increases. The horizontal path is intersecting a tight "U"
shape channel of quartz and calcite, with permeabilities in the order of nano-Darcies.
-
2020 April 01.
Build version ID = D3CA79
GeolOil is migrated to
Java-14,
while keeping legacy compatibility
with Java-8/x64-bits, Java-9, Java-10, Java-11, Java-12, and Java-13.
-
2020 March 01.
Build version ID = 940DCE
This release incorporates a downloadable GLOG learning example
to estimate RHOM matrix density ρm
using only log curves without any core laboratory measurements. An accurate RHOM estimate is needed to
compute porosity, water saturation, and estimate a permeability correlation equation.
-
2019 December 30.
Build version ID = 211CFA
Icon flags to tag wells observing Gas-Oil-Contact (GOC), and Water-Oil-Contact (WOC).
Minor improvements on Graphical User Design (GUI) buttons. Software model is called now 2020, with soon upcoming new specifications and features.
Java-8 is deprecated and will be removed in a future release of GeolOil. It is still functional for backwards
compatibility. Users are encouraged to migrate to JDK 13 or newer.
-
2019 November 22.
Build version ID = DCCECE
Three new method functions were added to estimate rock matrix density from easily available log data.
They are the perfect companion to GeolOil's RHOM
mineral solvers:
(25) In not too clayey rocks and no gas zones, RHOM is estimated by matching the behaviour of the curves Bulk Density
and Neutron Porosity. It is similar to cloud cross-plots to detect main lithology, but its output
is instead a whole RHOM curve varying with depth MD. The method even incorporates a correction for small shale content VSH to
improve accuracy, and also aids to detect gas zones: As the method doesn't converge for gas, it may be a clue
that suggests the presence of some free gas.
(23) & (24) When there is core porosity data, and either a bulk density or neutron porosity
curve, RHOM is estimated but matching which grain density succeeds to replicate the porosity values measured on the core
(make sure that the core is correctly shifted). These two functions provide useful reference estimates even when
core grain density values are available, as in some cases values reported by the lab are no very reliable and may
underestimate the correct RHOB.
-
