Laboratory Determination Of Porosity For A Vugular Carbonate Core Section By Water Immersion Method - Is It Effective Porosity?, Nolan Shula

The Research and Scholarship Symposium (2013-2019)

Porosity is one of the most vital characteristics in hydrocarbon reservoir evaluations, affecting the methods implemented in the completion process and the efficiency of the production process. Several methods are used for porosity calculations, but due to both lithologic and downhole drilling factors, these values can range more than ± 5%. Also, most limestone reservoirs contain multiple-porosity systems, which lead to effective porosity concerns, especially when secondary porosity is a significant factor. Therefore, through both geophysical wireline log analysis and basic laboratory analyses, this project compared total and effective porosity values of a vugular Onondaga Limestone pinnacle reef core section …
