Elfen Wellbore Software Elfen Wellbore Software

Elfen wellbore & well log v.1.7 

Release date: 11th November 2020


Successful hydrocarbon recovery has become increasingly challenging with the oil and gas industry exploring reservoirs under unfavourable geological conditions. Many operations rely on wellbore stability, usually provided by suitable mud-weight. Estimating the operating mud-weight window requires the combination of in-situ stress conditions, well trajectory and formation material properties to eliminate instability issues.


Elfen well log software is a simple yet powerful tool, which amongst other operations conducts analytical calculations to predict the onset of plastic yielding and damage around a wellbore. However, since analytical assumptions can become limiting, Elfen well log is directly integrated with Elfen wellbore, a dedicated finite element software package for modelling near-wellbore scenarios. These models can be used to assess more accurately areas of concern initially raised from analytical estimates.  Together with advanced constitutive material models, various complex mechanisms can be captured including:
