Solutions to Problems Faced in Well Log Analysis in fractured metamorphic Reservoir Systems Due To Multiple Porosities and Lithology’s
Abstract: Metamorphic rocks are the most bottomless non-terrigenous sedimentary rock and are made essentially out of transformative minerals. Most metamorphic rocks shape from calcareous stores that collect in marine conditions running from salt marshes to reefs to profound sea bowls. Unmistakable and one of a kind parts of transformative rocks are their dominatingly intrabasinal starting point, their essential reliance on natural exercises for their constituents and their powerlessness to change by …
