The Techlog wellbore software platform has been continually developed and tested for the last 20 years. The result is a leading wellbore-centric platform that is faster, with better usability and stability. With this new release, we are continuing our journey toward reliability and extensibility; offering usability improvement on zonation, annotation management, and upgrading KMOD workflow into Automatic Workflow Interface (AWI) engine. On the domain side, we continue to support 3D petrophysics workflow improving the auto population of tool settings and borehole parameters for forward modeling and inversion; as well as updating the environmental corrections algorithm and adding the support of trendlines for QElan computation.

 

With Techlog 2021, we continue to deliver continuous improvements to facilitate your processing and interpretation workflows:

Kmod

Now available as an AWI method and can be combined with any other AWI methods

Ability to preserve the seed property used for computation

Ability to save the model in the workflow and apply to another well without having to build again the model

Improve the error plot interaction

Annotation

Ability to define annotation for a single depth using tail

Ability to define the tail position to a specific depth

Ability to define background and border colors

Fixed an issue applying logview template with annotation dataset

Ability to create annotation on any track; no need for annotation track anymore

Other improvements:

Ability to display core image data stored as colored array using the new display option “Matrix RBG 16” under the display direction properties of the array inside the log view.

The full list of patterns and symbols defined in the patterns and symbols manager is now available from the global zonation dock window to be assigned to zones.

When a zone-type catalog is converted to global zonation, the catalog name is used to group global zonations resulting of the zone-type catalog categories conversion.

The grouping of global zonations in the Techlog platform project browser is reflected in the drop-down selection of the global zonation dock window.

Collapse and expand buttons have been added to the zonation hierarchy view in the global zonation dock window.

Impacted wells are listed to the user when renaming a zone.

Full synchronization is available on zone split between zone editor, AWI, and log view.

Zone description and property values are displayed as tool tips when mouse hovers the zone in the global zonation tree view.

HTML copy of the global zonation takes into account the zones hierarchy.

New property has been added to the log view zonation track to adjust manually the font of the zone names displayed in the track.

CRS

Update the CRS catalog to ESRII ArcGIS 10.7.1 and update engine to be aligned with Petrel E&P software platform and Studio E&P knowledge platform.

Use Studio platform companion XML file instead of CTL as storage for CRS information.

Encode the CRS well-known text (WKT) in the well property.

Calculator

Onboard the Calculator plug-in tool in the Techlog platform

Ability to easily perform user-defined equation-based calculations

Ability to run equations in single or multiwell

Ability to display results on log view

Ability to run computation over a zonation or using interactive selection intervals

Ability to load and save equations

History of pastused equations

Embedded endpoints calculator to help you quickly perform key computations such as porosity from density, water properties (Rw and salinity), shale properties, etc.

Petrophysics

3DPH

Autopopulation of tool setting and borehole parameters for forward modeling and  inversion: You will now have the tool setting and borehole parameters, such as mud density and borehole diameter, automatically populated. 3DP reads this information from the properties of the input measured logs or their parent datasets.

Fine tune the model through synchronization between dip sinusoids and the model:  You are now able to fine tune the local layer model through the new synchronization features, which link the dip sinusoids to the model:

Upon horizontal adjustment of a square log or dragging a boundary, the associated sinusoid is adjusted (update of the sinusoid depth and shape).

Upon update of the boundary dip (either through the mouse wheel or change of transverse dip), the associated sinusoid shape is updated.

Upon creation of a boundary, a corresponding sinusoid gets created and displayed in the same track where other sinusoids are displayed.

Upon deleting a boundary, the associated sinusoid is deleted, too.

Upon removal of the unwanted sinusoids in the log view display, the associated boundary is removed, and the square logs are updated accordingly.

Quanti.Elan

Now allows using variables, in the parameter slots, for clay parameters (e.g., shale resistivity, wet and dry endpoints). This enables using wet clay endpoint trendlines for the computation.

You are now able to incorporate, into Quanti.Elan solver, the fast neutron cross section (FNXS) and neutron porosity (TPHI) measurements from Pulsar multifunction spectroscopy service. These measurements are associated to linear response equations in Quanti.Elan; and help to differentiate and quantify gas-filled porosity from liquid-filled porosity and very low porosity formations.

Environmental corrections

Techlog platform now supports processing and environmental corrections of Schlumberger ThruBit through-the-bit logging services gamma ray, spectral gamma ray, neutron, density, induction resistivity and laterolog resistivity.

Techlog platform now supports processing and environmental corrections of the following Schlumberger LWD tools:

OmniSphere DN slimhole petrophysics evaluation-while-drilling service (ADN4B) tool. This is covered in adnVISION azimuthal density neutron service standard resolution, density high resolution, image derived density, neutron, azimuthal neutron, and density caliper methods. 

adnVISION service 825 with stabilizer size of 10 1/8 in. This is covered in adnVISION service density standard resolution, density high resolution, image derived density, 825 neutron, and density caliper methods. 

Techlog platform now performs neutron processing and environmental corrections of Schlumberger LWD stabilized adnVISION service 825 (SADN8) tool in a new standalone method. The is due to an update in the type of input count rates (from sectored waveforms to average) for the method. The update is aimed at alignment with the enhancements performed on the log data acquisition system.

The entire adnVISION service environmental correction methods have been updated (inputs and parameters). This is aimed at alignment with the enhancements and upgrades performed on the log data acquisition system. The adnVISION service environmental correction workflows generated in previous versions of the Techlog platform will need to be rebuilt in Techlog 2021.1.

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