New Software Release

Techlog 2022.2 Now Available

Wednesday, 21 December 2022

Product overview

The Techlog wellbore software platform has been continually developed and tested for the past 20 years. The result is a leading wellbore-centric platform that is faster, easier, and more reliable.

This new release continues our journey toward reliability, extensibility, quality, and a better user experience—delivering important new updates for zonation, Python, the Studio E&P knowledge platform, a new technology preview for Pickett plots, and a new feature called Tips and Tricks. 

On the domain side, we continue to enhance the Techlog platform’s 3D Petrophysics modules, improve  Quanti.Elan, NMR, TBA, and geomechanics, while making important enhancements to the wellbore image.

Key features of this release

Zonation UX

  • Improved visibility and direct editing of zone description (in dock window)
  • Search and filtering available for global zonation
  • Windows default selection of zones (Ctrl or Shift)
  • Improved color schemes for zone selection 
  • Saving of global zonation at other levels (from global zonation dock window)
  • Better visibility for active and inactive zonation
  • Simultaneous deleting of zonation dataset with its associated global zonation
  • Italicization of unused zones in global zonation 
  • Global zonation savable at different levels along with LogView dataset
  • Forbidden sign (red circle) removed from many scenarios for seamless zone creation through LogView 
  • Zone selection in plot and LogView retained even if you apply or remove filter in project browser

Zone Editor

  • Opens from global zonation dock window
  • Syncs with global zonation dock window (zonation name displayed on title bar) 
  • Supports drag and drop of zonation datasets 
  • Supports right-click to open zonation dataset 
  • Guides zone creation with intuitive prompting
  • Saves zonation datasets through contextual action, along with global zonation

Tips and tricks

This new feature is designed to help new and intermediate users get up-to-speed with Techlog platform workflows.

  • New dock window (can be docked, displayed, or hidden)
  • Contextual to a specific Techlog platform object (plot, method, etc.); displays different contents for category or method  
  • Linked to Guru in-context guidance and support software for extra information.

Pickett plots 

The new interface for Pickett plots (technology preview) offers the following improvements:

  • Always-on display template to drive the plot display
  • Easy variable selection from the data list
  • Dynamic number of water saturation lines
  • Easy copy (Ctrl-C) equations from the plot’s legend
  • Easy adjustment using three graphical points to control the a, m, n, and Rw parameters:
  • Easy hiding or display of the data management pane
  • Swap mode for easy visualization between different wells  
  • Support for undo (Ctrl-Z) and redo (Ctrl-Y) actions

Python support

Using the Python API, users can access, manipulate, and get information about the different components of the application workflow interface (AWI) or any Python AWI.

  • Manipulate inputs
  • Get easier access to the list of parameters 
  • Get a list of family/unit and palettes in an AWI
  • Get LogView IDs generated with AWI
  • Force the layout template mode 
  • Move the position of the method in the workflow
  • Save and load workflows and workflow templates
  • Export Techlog platform data as .tlpx from project, import buffer, export buffer, and trash.

Studio platform

The Studio E&P knowledge platform now provides additional features to improve the user experience:

  • Data objects can be renamed in the repository browser using right-click 
  • Dip properties correctly displayed in the repository browser properties pane (e.g., azimuth-associated variable, dip height-associated variable, etc.)
  • Digital log information standard (DLIS) properties have white space removed during import to prevent character limitations when sending data to the Studio platform.



New functionality enables efficient building of models containing both the initialized parameters and your customized parameters.

  • Temperature, pressure, and salinity-dependent parameters are computed per depth during initialization. Automatic population of parameters can be controlled through right-click selections on the parameter cell 
  • “Do not populate from initializations” desynchronizes the parameter from initialization results, so that the cell value does not change when initialization results are updated
  • “Populate from initializations” synchronizes the parameter with initialization results, so that the cell value gets updated, when initialization results change
  • Individual parameters can be copied from a single zone to all zones for which a model has been defined
  • In a multiwell dataset model, parameters from a zone in one well can be copied to similar zones in all other wells.

3D Petrophysics (PIPER)

Pixel inversion processing with enhanced resolution (PIPER) is now available to SLB customers as a processing service for some SLB logging-while-drilling (LWD) propagation resistivity logs: 

  • Corrects logs for shoulder bed and dip effect
  • Provides true resistivity (Rt) in formations with apparent dip up to 70°
  • Does not require a formation model defined beforehand 

3D Petrophysics (Usability)

  • Undo or redo edits performed on 3DPH local layer model, including changes done on both layer geometry (boundary positions and dips) and layer log properties
  • Enhanced DOI mask visualization and display settings to intuitively ensure alignment of the mask display with local layer model limits 
  • Enhanced display of inversion and forward modeling progress bars so they are not hidden behind other dialog boxes.  

Nuclear Magnetic Resonance (NMR)

  • Stacked 2D maps can be displayed over the desired depth interval to visualize an averaged map and NMR porosity value.
  • Display palettes can be assigned with ability to adjust their limits.

Thin Bed Analysis

  • LowRep develop endpoints method now enable hydrocarbon-corrected outputs to be assigned to consistent families.
  • Sand and shale points on crossplots are now connected by a line, for improved visualization and correlation. 

Environmental Corrections

  • Density caliper environmental correction method for the adnVISION azimuthal density neutron service enables output of two density caliper quality indicator arrays for the OmniSphere DN slimhole petrophysics evaluation-while-drilling service.
  • These arrays give indications of the reliability of caliper data around the borehole. 
  • The method now outputs eight calipers covering 360° which factor in the photoelectric effect.  


Stress inversion

  • Inversion of tectonic strains now honor observations like closure pressure, breakdown pressure, and breakout width, among others.
  • Users can interact with the posterior plot and calculate wellbore stability to verify how the selected solution looks in context with the observations.

Stochastic wellbore stability

  • Enhanced single-depth calculation within stochastic wellbore stability now makes it possible to calculate sensitivities around different combinations of inclinations and azimuths besides the default setting taken from the trajectory.


The Techlog platform is suitable for all geoscientists working with wellbore data and associated interpretation across multiple domains, performing collaborative workflows from exploration to production.
