Petrolib tutorials

Petrolib is a python package designed to help users perform petrophysical analysis by estimating petrophysical parameters such as:

  • Volume of Shale using various methods like Clavier, Stieber and Larionov methods
  • Porosity - Effective and Total porosities using the density and Wyllie's sonic methods.
  • Water Saturation - using both archie and simmandoux methods
  • Permeability

In addition to estimating these parameters, log plots are automatically displayed for proper interpretation. Also a pay summary result/dataframe is produced to help quantify the over-all quality of the reservoirs. Cutoff such as the porosity, shale volume and water saturation are applied to flag pay regions. The pay summary include:

  • net, gross and not net thicknesses
  • % net-to-gross
  • average volume of shale
  • average porosity
  • bulk volume of water
  • water saturation.
