DESIGNED FOR
Petrophysicists, geologists, geophysicists, engineers and explorationists involved in all phases of reservoir evaluation in shaly sand provinces
YOU WILL LEARN HOW TO
Determine the nature, volume and distribution of clay minerals and shales in shaly sands, and their impact on the analyses of cores and logs
Integrate petrographic, core and log data to significantly improve reservoir evaluation in shaly sands and other rock types containing significant amounts of microporosity.
Learn how rock typing can bring order out of chaos on porosity-permeability cross-plots
Evaluate effective and total porosity, fluid saturations and producibility of shaly sands using time-tested specific methods
Evaluate the strengths and weaknesses of advanced logging tools for characterization of shaly sands
ABOUT THE COURSE
This course tackles the important and nontrivial problem of practical formation evaluation in shaly sand provinces. The presence of clay minerals and shale laminations strongly affects the physical properties of the reservoir rock and induce significant effects on the response of most logging tools; these perturbations often result in low resistivity/low contrast pay zones that can be significant hydrocarbon producers but are often overlooked. A properly designed analytical program (cores and logs) for the evaluation of shaly sands can add significant reserves in existing fields and can allow for the rapid identification of potential by-passed pay zones in exploration wells. The course is practical and participants are given laboratory and field problems to emphasize the instruction. At the end of the course, the participants will be able to identify and evaluate pay intervals in shaly sands.
