Abstract

At first, Flow unit study helped to interpret Petrophysical potential of complex reservoir behavior. Core analysis such as Porosity, phi, Permeability, k, and permeability/porosity ratio (computed r35 port size in microns) and Winland r35 plot were used for the this progress. Lorenz and stratigraphic modified Lorenz plot indicated that five rock/pore units were indictable, each with an individual flow behavior called Flow Unit. They are defined as, disperse vugs (b), touching vugs (c), meso (m) and micro port size (e) and fracture (a) units. The flow units (c) and (m) constitute 55% and 20% reservoir flow respectively. In other side they are contained only 25% reservoir storage capacity. But flow unit (b) imparts 22% reservoir flow and 76% storage capacity. Different digenetic processes such as solution, cementation, dolomitization and anhydrite nodules precipitation affecting from Pyrnean disconformity have caused that flow units were irregularly distributed within whole reservoir. At second step porosity and water saturation were 3D modeled. Its results support complexity of reservoir situation depending to various Petrophysical factors. Lower reservoir, Jahrum fm, although contains better Petrophysical properties but production is mostly focused in upper reservoir or Asmari fm, where flow units (c) and (a) are generated.
