Brand new Techlog K.mod
Techlog K.mod is brand new in Techlog 2021 and has additional capabilities. It can now support automatic workflow interface (AWI), with the ability to preserve the computational seed property into workflows and apply it to other wells.
Because Techlog K.mod supports automatic workflow interface (AWI), petrophysicists can use it to preserve the seed property used for computation and save the model in the workflow. The saved model can be applied to another well without having to build the model again.
(*) The Techlog K.mod module extracts essential information from log data to predict nonrecorded parameters (ะค, K) and reconstruct missing or poor quality measurements to compensate for bad hole conditions, environmental effects, acquisition problems, etc.

Techlog Calculator now available for single or multi-well improved analysis
Techlog Calculator is available in Techlog 2021 with improved properties, enabling users to gain meaningful insights into computations and equations.
.jpg?la=en&hash=B07CFAA96FFD668B043D81C3B0632330CB41D8B3)
Techlog Calculator was previously available as a plug-in in the Ocean software development framework. In 2021, we embedded its functionalities into the Techlog Base License. Techlog Calculator bridges the gap between the data editor and math processing functions in the Techlog wellbore software platform.
The new Techlog Calculator enables petrophycisists and geoscientists to drag and drop variables in single and multi-well environments. They can also quickly and easily conduct syntax management with in-built operators, perform proper family assignment logic, using zones in multiple ways and with dual modes of output generation, and create visualizations of unsaved variables—essential for validating any field specific correlation. The equations formed can be saved and reused in the future.
In addition, the new version of Techlog Calculator includes “Endpoint Calculator” which enables the computation of essential petrophysical parameters for advanced interpretations.
Techlog Calculator summary:
-
Easy and quick computation of data for single/multi-well environment.
-
Variable(s) drag & drop operation for input selection.
-
On screen operator buttons for efficient syntax management.
-
Allows equations to run either on full interval, user-specified intervals, available project zonation or on intervals created by interactive selections.
-
Options to display unsaved outputs in LogView.
-
Automatically applies family assignment rules if output family and unit are missing in the computation.
-
Outputs can be generated either via ‘update’ or ‘overwrite’ mode.
-
Equations can be saved and reused as per user requirements.

Petrophysics: new updates to Quanti.Elan solver
Differentiate and quantify gas-filled porosity from liquid-filled porosity and very low porosity formations, with the Quanti.Elan* multicomponent inversion solver. Use shale trendlines for inversion computations.
Techlog 2021 enables petrophysicists to incorporate fast neutron elastic scattering cross section (FNXS) and neutron porosity (TPHI) measurements from the Pulsar multifunction spectroscopy service into the Quanti.Elan multicomponent inversion solver. The measurements are associated to linear response equations in the Quanti.Elan solver and help differentiate and quantify gas-filled porosity from liquid-filled porosity or very low porosity formations.
Petrophysicists can assign a variable to the shale resistivity and a variable to the wet endpoint, for the clay minerals specified in the Quanti.Elan solver model.
Quanti.Elan solver uses the variable parameters for the computations accordingly. This new functionality enables shale trendlines to be used for the mineral and fluid inversion process.
*With the Quanti.Elan solver, petrophysicists can save and then easily reapply models to new data—the ability to combine outputs from several models improves the accuracy of final results.

Techlog 3D Petrophysics for high-angle well evaluation
With Techlog 3D Petrophysics, petrophysicisits can fine tune the local layer model through synchronization between the dip sinusoids and the model. They can also auto-populate tool settings and borehole parameters, to enhance the user experience.
Techlog 2021 develops the possibilities in Techlog 3D Petrophysics synchronization. Petrophysicists are now able to fine tune the local layer model through new synchronization features which link the dip sinusoids to the model. The local layer model can be created and enhanced in just a few clicks, through visual guidance of the sinusoids.
Techlog 3D Petrohysics tool setting and borehole parameters, such as mud density and hole diameter, can be automatically populated from the properties of the measured logs.

Accelerate processing and interpretation with the new borehole environmental corrections
Techlog 2021 now supports processing and environmental corrections of ThruBit through-the-bit logging services measurements, including gamma ray, spectral gamma ray, neutron, density, induction resistivity and laterolog resistivity measurements, in addition of Schlumberger Logging While Drilling (LWD) Services. All adnVISION* azimuthal density neutron service environmental correction methods have been updated (inputs and parameters). This is fully aligned with the enhancements and upgrades performed on the log data acquisition system.
*The adnVISION provides azimuthal borehole compensated formation density, neutron porosity and photoelectric factor measurements.
