New Software Release

Techlog Production Logging 4.1 Now Available

Monday, 09 December 2019

Product overview

The Techlog Production Logging module enables you to perform a complete production logging workflow, from raw acquisition data to interpreted zonal flow rates to yield information about the type and movement of fluids within and near the wellbore. It uses the powerful visualization of the Techlog wellbore software platform and integrates production log measurements with other modules on the Techlog platform to perform a comprehensive cased hole evaluation. This in turn enables the user to optimize well and reservoir performance during the asset life cycle and advise on the intervention solutions.

The module utilizes an extensive library of fluid PVT correlations and industry-leading flow-assurance science from the OLGA dynamic multiphase flow simulator and includes comprehensive spinner calibration with automatic and manual control over thresholds and slopes. Multisensor array tools, including FloScan Imager horizontal and deviated well production logging system, are supported along with display on cross section plots.

Release updates

Interpretation of production logging in injection wells might not be straightforward, as there can be some zone absorbing and some zones producing as well. This leads to the need of manual intervention while performing the interpretation. Manual intervention of absorbing zones is available now. This will ensure better and faster interpretation results.

  • Improved zonal flow rate calculation from the new OLGA simulator
  • Enabled manual intervention of absorption scenarios in rate calculation
  • Introduced capability of different phase flow having different unit at surface and downhole conditions
  • Well Performance Advisor (WPA) has removed the dependency on a fixed version of the PIPESIM steady-state multiphase flow simulator. The version of the PIPESIM simulator will be picked up by WPA automatically.
  • Introduced new license of production logging (PLOG-G1)


Techlog Production Logging is suitable for geoscientists and engineers, including petrophysicists, geologists, reservoir engineers, and production engineers.

The plug-in enables users to integrate production logging data with other petrophysical and geological information in the Techlog wellbore software platform.
