Permeability is one of the most important attributes to estimate in a producing field because is a measure of how the fluid will flow through the reservoir. A permeability model was developed for a thin reservoir located at Postle Field, Oklahoma, with the objective of accurately predict fluid flow under a CO 2 injection framework. Postle Field is located in the Texas Country, Oklahoma, and it is comprised of the Pennsylvanian age Morrow A sandstone of the Morrow Formation. The presence of high

This is not uncommon in the oil and gas industry since the average reservoir thickness in North America is 17ft (5m). It is of the utmost importance to understand the influence of permeability and the role of heterogeneity in fluid flow. High permeability zones have the potential to cause early breakthrough and poor sweep efficiency.
