Advanced Formation Evaluation
Topic:
Geology of Carbonates and Clastics
Core analysis to obtain porosity, and permeability
Shale Analysis: Elemental Capture Spectroscopy to give evaluations of lithology and shale volume, evaluation of dispersed and laminated shales, definition and measurement of the Cation Exchange Capacity (CEC)
