Schlumberger Techlog 2022.1

Schlumberger Techlog 2022.1

 

Release updates

Foundation

Usability

With Techlog 2022.1, we’ve delivered continuous improvements to facilitate your processing and interpretation workflows:

Python 3.9 upgrade

  • Upgraded Python compiler from version 3.6 to 3.9
  • Added application programming interface (API) to access and manipulate automatic workflow interface (AWI) from the Techlog platform or any Python AWI. These features help API users get information about the different components of AWI and change them.

Annotation

  • Improved date-time reference handling with a feature that allows the user to display data in LogView in date-time format.

Rock Physics

  • Advanced rock modeling functionality provides an integrated approach to create rock models for determining elastic and acoustic properties of rocks from petrophysical inputs. The rock model workflow can be used for both single and as multiwell environments. The functionality also offers an optimization workflow that uses an inversion algorithm to determine optimum rock model parameters to propagate to nearby wells in the field. This new method is available as a technical preview in the Techlog Geophy module.

3D plots for ‘basic’ subscriptions (DELFI environment only)

  • Added 3D plots to display when opening the plots without a GPU, such as the Wellbore Centric Grid display, 3D Field viewer, 3D DTS, 3D cross-plot (single and multiwell), 3D Sammon projection, and 3D Dendogram (Techlog Ipsom  module).

Petrophysics

Quanti.Elan solver

  • Added use of shale resistivity by Dual Water Elan equation:  In the Quanti.Elan solver, you can now use shale resistivity (Rsh) when working with the Dual Water Elan equation. When you choose this, the equation uses the shale resistivity parameter; bound water conductivity is computed for each clay from the input shale resistivity and is used in the computation accordingly.

  • Added outputs for water saturation (Sw), water saturation of the flushed zone (Sxo), and effective water saturation (SWE) from Quanti.Elan solver postprocessing: Postprocessing now outputs total water saturation in uninvaded and flushed zones. It also outputs effective water saturation. The same equations used by the Quanti.Elan solver are used to compute these new outputs.  

  • Added Quanti.Elan solver method property   to opt for update of either wet or dry clay endpoints upon update of wet clay porosity: Upon an update of wet clay porosity in the Quanti.Elan solver, you can now choose whether the wet or dry clay endpoints get updated. This is achieved through a new method property. The default is the update of wet endpoints.

3D Petrophysics for high angle well evaluation (3DPH)

  • Added new tabular view in 3DPH Local Layer model  : You can now interact with the 3DPH Local Layer model through the new tabular view. This window hosts the numerical representation of the model. It provides an editable and interactive interface, which is in full synchronization with the model. You can edit individual layer properties, fill up or down a defined layer property to other layers, show or hide certain layer columns, and copy the table content to Excel for subsequent use. These improve your 3DPH Local Layer model workflow efficiency. 

  • Enhanced inputs with PeriScope Edge multilayer mapping-while-drilling service’s directional anisotropy and Z-measurement channels by Rv Rh inversion: The Rv Rh inversion in Global Layer model   now accepts the PeriScope Edge service directional anisotropy and Z-measurement channels as inputs. With the addition of these new channels, the Rv Rh inversion could be run on any desired combination of the PeriScope Edge service conventional resistivity and directional channels. This new capability enhances the accuracy of inversion outputs, especially the inverted boundary positions and dips. The Rv Rh inversion is currently available to Schlumberger customers as a processing service only.

Nuclear magnetic resonance (NMR)

  • Added new Single-Depth 2D Map for Schlumberger NMR tools: Through the new NMR Single-Depth 2D Map   functionality, you are now able to visualize the 2D maps, resulting from inversions run with Schlumberger NMR tools. The following maps are supported:

    • T1 relaxation time vs. T2 relaxation time (T1T2)
    • Diffusion constant vs. T2 relaxation time (DCT2)
    • Diffusion constant vs. T1 relaxation time (DCT1)

Environmental corrections

  • Updated ThruBit through-the-bit logging services Spectral Gamma Ray (SGR) method  : The ThruBit services SGR environmental correction method now accepts GR counts spectrums as input, instead of average elemental yields (which was the case in Techlog 2021.2). This is aimed to align with the field data acquisition platform (MaxWell).   The method also now performs borehole Potassium correction.

Studio E&P knowledge platform

  • Removal of Oracle support: It is no longer possible to select Oracle as a database provider when installing the Techlog 2022.1 database.
  • Transfer improvements: In specific scenarios, the transfer performance has improved on both “Send” and “Retrieve all” operations. In addition to this, there is improved logic in the database relating to project workspace deletion.
  • Expose additional validation rules: The default behaviour is unchanged, but it is now possible to turn off validation warnings when sending zonation datasets without a defined Zone name. Note that disabling these rules can lead to legitimate zonation data in the Studio platform that will not be able to participate in Global Zonation workflows.
  • User management traceability: User operations (create, modify, delete) are now captured within a new database table for audit purposes and traceability.
