p:IGI+/Metis Transform version 1.19.x release

We are pleased to announce the release of version 1.19.0.10 of p:IGI+ and 1.19.0.7 of Metis Transform. This version includes a number of new features and performance enhancements, and is a advised update for all users of p:IGI+ in particular. 

This version includes the following changes with respect to 1.17.0:

New features (p:IGI+ and Transform)

  • Project files can be dragged onto the application to open a project.
  • Text, Excel and p:IGI-3 files can be dragged onto the application to launch the import.
  • Template files can be dragged onto the application to create the associated artefact.
  • Zip files exported from Metis Discover can be dragged onto the application and will auto-import using the linking template to easily bring data imported from Discover into p:IGI+ or Metis Transform.
  • Create a static sample set from a dynamic one to freeze the state at a given time.
  • A count of the number of wells imported is provided on the import summary screen.
  • The depth model for wells and samples has been simplified. The Kelly Bushing, Drill Floor and Rotary Table datums have been combined, and the data suitably migrated, to a Drillers Reference height datum. It is important to understand this value is the height of the measurement point on the drilling rig above the ground or water surface, and not an absolute elevation above a reference datum (e.g. mean sea level).
  • The above change has simplified the datums available for samples, and involved modifications to many artefacts, which are automatically migrated.
  • The sample depth datum conversion logic has been changed to assume an onshore well if the Ground Elevation is set. If Water depth is also set a lake / river based well is assumed. If only Water depth is set an offshore well is assumed. The property Onshore?.Well has been renamed Loc Char.Well and now can contain any string, although we suggest using Onshore / Offshore. This property no longer affects depth calculations.
  • The import table detection has been improved to work on a larger range of lab exports.
  • The harmonise dialogue has been reviewed and simplified to improve usability. Many enhancements have been added: the ability to harmonise only with a sample set / well (auto-selected from the page if one is applied to page); the ability to change the sample set / well being considered on the harmonise dialogue; automatic trimming of leading and trailing white space to ensure data is cleaned effectively, including visual indication of the presence and trimming of white space.
  • During import, when the user selects a property manually to link to, it is possible to accept the selected property and move to the next row, auto-selecting the next property in the analysis group.

p:IGI+ specific features

  • Autographs have been improved, with 18 new autographs, 2 autographs removed and 8 autographs edited. Of particular note are the following autographs for which the edits are such that interpretations conducted on previous version will need a revision:
  • Pr/nC17 vs Ph/nC18[*].Any – Maturity lines, present in the overlay layer, have been adjusted to be equal on both the x & y axis
  • H29ab/30ab vs H35abS/34abS[*].Any – Ratio on the x-axis property H30ab/H29ab has been changed from a/b to b/a to correctly fit the environment interpretation regions; which have been coloured and made clearer.
  • Ster/Hop vs t26/t25[*].Any – The environment underlay interpretation regions have been reversed to correctly fit the format of the Ster/Hop ratio, displayed in a/a+b.
  • H27Ts/H27Tm vs H29Ts/H29ab[*].Any – The maturity underlay interpretation regions have been adjusted in light of data trends from the IGI compiled UK, OGA released geochemical database. A sample’s maturity is equivalent with respect to both axis property ratios. Equivalent VR (Roe)values are given in relation to H27Ts/H27Tm ratio values.
  • IsoheptRat vs HepRat[*].Any – The kerogen type curves presented in the graphs overlay layer have been adjusted in light of data trends from the IGI compiled UK, OGA released geochemical database.
  • MPR vs MPI-1[*].Any - The maturity underlay interpretation regions have been adjusted in light of data trends from the IGI compiled UK, OGA released geochemical database. A sample’s maturity is equivalent with respect to both axis property ratios. Equivalent VR (Roe)values are given primarily in relation to MPI ratio values (using the %R(MPI<1.35 equation). Autograph name change also changing MPI(1) to MPI-1.

Metis Transform specific features

  • In Staging merge and upload, when a project sample matches 100% to a Staging sample, even if there are other (lower percentage) candidates, select the 100% match to merge – conflicts will still be shown.
  • In the Staging merge when a Staging sample matches two (or more) project samples, do not propose to merge with any of them (used to be the last one to match was selected).
  • The dialogue to select the Metis Staging area (server) to which data should be uploaded has been improved to more clearly show the currently selected server and enable a hyperlink to quickly access the corresponding Metis Discover in your default browser.

Metis Discover specific features

  • The user can select which subset of analyses to export from Metis Discover, reducing export times and improving the ability of the user to obtain the data desired, including the ability to select all analyses for export.
  • Map always shows all well and sample locations on load.
  • Various minor bug fixes, in particular improved property selection.
  • User interaction with property selection has been improved.
  • The export of text files from Metis Discover uses a wrapping symbol to enable import of fields containing column delimiters (tab).
  • The properties shown in the data preview can be modified by the user and will be remembered by the web browser.

Fixes

  • Improved the performance of export across the software.
  • Equations will be calculated for new properties added to the system where the inputs already exist (essential in Metis Staging). This will also write provenance if necessary.
  • Statistics calculations corrected for the unassigned group when a palette is applied.
  • All location properties are now populated on the well location tab.
  • All other well properties are now editable from the well artefact.
  • Changing the meaning of the Kelly Bushing Elevation to Kelly Bushing Height had rendered the datum conversion from KB (Kelly Bushing) to e.g. SS (Sediment Surface), and MSL (Mean Sea Level) incorrect for onshore wells. This has been updated, but it is important that users are aware that we use the Drillers Reference *height* (the height above the ground / water surface, and not the absolute elevation above mean sea level). It is possible (but unlikely) that sample depths calculated with respect to SS or MSL could be wrong for onshore wells.
  • Entering very (unrealistically!) large values to integer based properties no longer causes the application to crash.
  • Column alignment in the Staging upload in Metis Transform is always maintained.
  • The results of statistics on the unassigned group from a palette are always correctly calculated.

Property model changes

  • A range of new properties (~100 new properties) has been added to support UK OGA data compilation work, and other clients.
  • Thompson gasoline ratios added to the Gasol-GC group along with Mango ring preference ratios added to all appropriate analysis groups.
  • A whole suite of GC-IRMS deuterium isotope ratio properties to compliment the δ13C properties already present.
  • New deuterium isotope ratio properties for the different separation fractions present in the isotope analysis group.
  • A new TAI scheme class: User 1-N scale to accommodate date not captured against a 1-5 scale or 1-7 scale.
  • New sample properties: Description.Sample and Volume.Sample.
  • A new Thermal analysis group to allow the storage of raw and corrected temperature data.
  • Simplification of the well depth and location type treatment (see datum and related changes above.)

Known issues

  • In older projects the Pyrolysis summary page might not open as some of the properties have been removed. To open the page remove the properties S2-OM.Any, PI-OM.Any and Sh-OSI.Any which have been removed from the system.
  • Project merge can get slow in Metis Transform when there are static sample sets present. We are working to fix this – to improve project merge performance you will need to delete the static sample sets, save the project, close it and re-open it.

 

We believe this release of p:IGI+ is capable of being used operationally to pursue a basic petroleum systems analysis geochemistry study, and have used it extensively in house to do this. It does not yet support the full workflow encompassed in p:IGI-3, but offers many advantages over p:IGI-3, including a more complete property model, greater interactivity, and all that with undo support for all important operations.

 

 

 

 

If you wish to explore and test p:IGI+ then an example demo project is available for download from our website.

We’d welcome any feedback you have on p:IGI+, and note that there is a developing online user guide. We intend to develop sections of the user guide as questions arise. There is also a support site which contains some frequently asked questions and can be used to request specific support, along with the email support@igiltd.com.
