GeolOil - What's new : Major Software Releases

Following down is a list of some stable versions released. Please make sure you always have the latest version installed.

  • 2024 March 17. Build version Sha1 ID = 04EACD
    User parameters and LAS Tops, can be simply entered now on any box constant function or script, by prepending its keyword with the sigil % For instance, type in a box %Salinity, and it will retrieve its value of say 43,000 PPM NaCl from the User Parameters section table:

  • 2024 March 08. Build version Sha1 ID = 873C5C
    This release implements the Nugent equation to estimate the porosity cementation exponent m in buggy carbonate rocks. Not be confused with the Rasmus equation to estimate fracture porosity. The rock must be buggy for the equation to be applicable.

  • 2024 February 05. Build version Sha1 ID = 44948A
    GeolOil adds a built-in function to estimate effective porosity in water bodies from deep resistivity only. As soon as a water body like a water pocket or an aquifer is detected in the formation, the method provides a reliable alternative method to estimate porosity. Of course, an accurate estimate of Rw is needed. I also other source curves like bulk density, neutron porosity, or sonic transit time are available, the method allows to validate and compare several estimates. The technique is reliable in water zones. For pay zones, the estimated porosity is severely under-estimated, as seen on the log-plot below after the computation panel.

  • 2023 November 29. Build version Sha1 ID = 6CA65C
    This release implements the computation of the m porosity cementation exponent for shaly sands, using the GeolOil-Pickett modified equation. The method has a general applicability, and reduces to the standard Pickett plot equation for clean rocks when Vshale=0.

  • 2023 November 06. Build version Sha1 ID = B1C9BE
    The tab 2D sets ⋰∴  shows all the Pearson linear correlation coefficients between curves. Just hover the mouse on a selected curve to show all the r correlations with the remaining curves.

    The figure below shows (the beige panel) the correlations in a gas reservoir between its gas saturation SG and other curves. For instance, the linear correlation between the gas saturation SG and the oil saturation SO is r=-0.7917. That is, there is a trend that if the gas saturation decreases, the oil saturation increases. And that is consistent with a negative correlation with depth, as r=-0.3999 is negative, so the deeper the depth, the smaller the gas saturation, as expected for a gas reservoir.

GeolOil Linear Pearson r correlations

  • 2023 October 01. Build version Sha1 ID = 8297B1
    A dedicated brand new section ~User Parameters has been added to store user defined constants and parameters. Now there is no need to add them to the original read source ~Parameters of the well. Yet it keeps the same syntax to refer values. For instance, %RhoF refers below to the constant value of 0.80 grams/cm3 for the fluid density around the wellbore wall with a mix of mud and gas in a gas reservoir.

GeolOil User Parameters Constant Section

  • 2023 September 07. Build version Sha1 ID = 03305F
    GLS Script compiler now allows to specify constants from the LAS & GLOG Sections: ~Parameters, ~Well info, and even the non-standard (but recommended) ~Tops section. For instance, if formation water Salinity has a value of 35,000 NaCl PPM, it can be referred anywhere in a script by prepending its keyword with the Sigil "%": %Salinity will behave then like a variable with a constant value of 35000 for all log depths.

    All GeolOil models come with a double split window viewer of raster well logs, so you can visualize curve leyends, strokes, and scales together with curve plots, or compare two zones. No matter how large would be the raster TIFF files (or other image formats, like JPG, PNG, GIF, or BMP), you will be able to load and view several well raster files in the application besides other windows of workflows.

  • 2022 January 21. Build version Sha1 ID = C2F2E5
    Multiwell Work-flows are now available in GeolOil. Once you have a common alias set for a collection of wells, pair the aliases with the mnemonic log curves, define a workflow as a sequence of functions and export it. Then any well can import the workflow and run it automatically. It may save hours of expert interpretation work as long as the wells are similar.

    GeolOil is now adapted and recompiled with minor changes to run seamlessly on Windows-11 while keeping 100% legacy compatibility with Windows-10, MacOS, and Linux. Windows-11 allows to run GeolOil slightly faster as the OS yields more CPU time to foreground processes.

  • 2021 December 05. Build version Sha1 ID = 1EDD77
    Once the aliases for mnemonics are fully paired, GeolOil suggests suitable curve numbers to enter into input boxes of each equation work-flow. This new feature of the Alias Editor, is some sort of light-weight AI guesser for specific curve inputs.

    2. A display template system, with export and import capabilities for all tracks with its curves, colors and fillings.

    3. 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 Sha1 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 Sha1 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.

    Improved Button-SpaceBar focus policy for a better user experience.

  • 2020 May 16. Build version Sha1 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.

It is still functional for backwards compatibility. Users are encouraged to migrate to JDK 13 or newer.

  • 2019 November 22. Build version Sha1 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.

Functions Panel shows how to estimate grain density RHOM from bulk density and neutron porosity curves
