A discrete palette editing Tool
The catalogue management has been simplified by merging patterns and symbols into one window.
To simplify the geologist’s journey in the Techlog wellbore software platform, we introduced a new way for users to create palettes:
- We simplified the catalogue management by merging patterns and symbols into one window.
- Using the search function, you can now classify your patterns and symbols.
- Each symbol and pattern can be classified and flagged as ‘favorite’ for each workflow, with the added ability to filter your favorites.
- You can now create a discrete palette based on a pattern.
- Palette discrete values can be edited by the user from the dock window.
- Colors and patterns can be applied to a discrete value.

Making lithology management easier
We continue to improve the overall usability of the software providing an easy way to create and brush lithology or any general flags.
You can now use your palette to create your lithology:
- Patterns and colors can be assigned to a discrete value palette and you can now brush a lithology onto any track using a palette.
- The lithology can be saved as a variable to the reference dataset with its associated palette discrete value.
- You can now display the lithology palette information vertically in the LogView header or use the dynamic header.
- You can easily convert lithology to zonation.

Increased capabilities with Python 3.6
Python 3.6 enables advanced customized workflows with improved stability.
With Python 3.6:
- We improved the stability and startup time is now fully transparent for users.
- You can now run Python out of process, giving you the freedom to do more.
- Full support for advanced libraries: You can use external Python IDE, like PyCharm, to create and debug your Techlog platform Python scripts.
- Python 3.6 Advanced Library with the latest versions are now available.
- Use pip install for to easily install additional libraries.
- The new Python API has been added to manage the history entry at a specific time stamp for variable/dataset/well. Using this API, you have the possibility to sanitize your Techlog platform projects before you move them to the DELFI cognitive E&P environment.
- Python API has been added to manage discrete palette creation.

Geomechanics
New visualization cross-plot for pore pressure prediction
Visualize results in the regular Logview window and compare the results in a pressure versus TVDSS cross-plot, for a clear overview of the model with respect to the observations.
Calculate pore pressure for different lithology types (either shales or non-shales), and compare the results using the cutting-edge visualization tools available in the Techlog platform, to verify whether the observations match the model results, and provide predictive models for your field developments and exploration wells.

Streamlined horizontal stress calculation
Calculate minimum and maximum horizontal stresses using industry recognized workflows.
Depending on the available information, horizontal stresses may be calculated either as a simple relationship between the vertical effective stress and the horizontal effective stress (effective stress ratio method) or using the theory of poroelasticity, which requires elastic properties, or as simple as a proportion of the minimum horizontal stress.
As a user you will be able to calculate the minimum and the maximum horizontal stresses in a single workflow.

- Merged multiple steps (initialization, calibration and apparent velocity) in one
- Single pass processing
- Interzone calibration option (easy to use)
- Interpolate calibration
- Extend calibration
- Using calibration from other flow conditions

Petrophysics
Structural model integration between the Petrel platform and Techlog 3D Petrophysics
Exchange results between Techlog and Petrel is now possible.
Integration of structural models into high angle well evaluation workflow is now possible
You can import the curtain section geometry point sets generated in the Petrel E&P software platform into the Techlog wellbore software platform and load them to 3DP-High angle well evaluation for global layer geometry initialization.
The curtain section geometry point set could have been created in:
- Petrel 3D window, using the calculator application
- Petrel Reservoir Steering or Shale Geosteering
The loaded geometry can then be used for construction of the layered earth model.
This workflow will enable you to efficiently integrate your structural modeling with high angle well evaluation workflows in 3DP.
Techlog 3D Petrophysics also allows you to build layered earth models to derive the true formation layer properties. The process involves use of logs, borehole images, and boundary mapping technology information to create formation geometry and layer log properties. The resulting formation layer geometry can be exported as point sets and used in the Petrel E&P software platform to update the structural models.
You can now add accuracy to your structural models through integration of the geometry interpreted in Techlog 3D Petrophysics.

Automatic characterization of thin bed geometry and density from borehole images
Use borehole images to guide accurate and automatic definition of formation layer geometry and density/PEF properties.
You can use borehole images measured by the EcoScope multifunction logging-while-drilling service and the adnVISION azimuthal density neutron service to automatically define local layer models consisting of layer geometry and density/PEF properties. The density inversion functionality ensures accurate and efficient definition of the model in a reasonable time frame.

Techlog 3D Petrophysics enhances resistivity forward modeling
Techlog 3DP enables you to evaluate the individual contribution of boundary dip or invasion into the forward modeled responses. You can now use the resistivity modeling mode to achieve this, choosing one of these three options:
Use defined model: Forward modeling is performed on the defined formation model. The model dimensionality flags show where dip or invasion effects are honored. They also show the quality of the invasion modeling.
Exclude invasion: Forward modeling is performed on the formation model while assuming that the entire interval is uninvaded. 3DP uses the 1D+Dip code to model the responses.
Exclude dip: Forward modeling is performed on the formation model while assuming that boundaries are perpendicular to the well trajectory. 3DP uses the 2D code to model the responses.
