Biostratigraphy and chemostratigraphy are not always available in well correlation projects, or do not always provide sufficient constraints. Consequently, correlations and stratigraphic models derived from them can remain uncertain. CycloLog® is well correlation software which:

  • Enhances interpretation methods. Interpretation with CycloLog® is faster and of higher accuracy owing to INPEFA®.
  • Gives reproducible results. Less time is spent on discussing correlations.
  • Is fast and versatile – INPEFA® can be applied on multiple well logs of any type and resolution, in just a few simple clicks.
  • Limits bias – INPEFA® calculation is data-driven thus unbiased when compared to model driven interpretation.
  • Has efficient workflows. CycloLog supports the workflow of petroleum geologists working with well logs.
  • Has a fast and informative log display. 
  • Allows for an in-depth analysis of your logs in relation to your established stratigraphic framework, using several functions.
