Porosity Evolution in Sandstone Reservoirs

Estimated Time to Complete:

2 hours 20 minutes

(average of 20 minutes per Subtopic)

Describes porosity evolution in all sandstone reservoirs, regardless of depositional environment, and reviews factors that control primary and secondary porosity. Evaluates tools and techniques used for description of sandstone porosity and porosity evolution. Illustrates applications of porosity evolution through case studies.
