Course description

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.

Who should attend?

Petrophysicists, geologists, geophysicists, engineers, and explorationists involved in all phases of reservoir evaluation in shaly sand provinces.

Learning about fundamentally altering processes in clay minerals and tool responses. I like working through various models and how to imagine the rock and logs together.

I thought we spent a good amount of time on everything. The explanations and deep discussions about physics and chemistry. I also really liked the pre-question answer session. The discussions were also very good.

Time devoted to each section seemed appropriate for the overall course subject. Exercises and the reinforcement the provide with the course material.
