... Introduction This paper presents the methodology used to deliver a consistent set of rock types, with petrophysical outputs of porosity, water saturation, and permeability, using a class-based machine learning (CbML) method. This novel tool is designed for summarizing the unique...

... Abstract Fluid identification is one of the greatest challenges in Sichuan Basin, China. The tight carbonate reservoirs have very strong heterogeneity in mineralogy and pore structure without a unified free water level, resulting in the frequent failure of water saturation calculation...

... production plans along the shale formation of interest. A well having complete data as mentioned above is used in this study. At first, the main conventional petrophysical properties such as clay content, porosity, and water saturation are interpreted by using triple combo logs and supported with sonic...

... Water Level (FWL) and Oil Water Contact (OWC) are determined by integrating formation pressure test, flow test, and well log data (especially for resistivity log) which can also be used to define the reservoir wettability. Then, the vertical water saturation is interpreted by simple Archie's equation...
