Quanti.Elan: Use of Shale Resistivity Through Resistivity Equations

In the Quanti.Elan solver, you can now use shale resistivity (Rsh) when working with the Dual Water Elan equation.

When you choose use shale resistivity (Rsh), 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.

2021 Features

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.

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. 

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.

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.

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.
