f High Permeability Streaks Characterisations in Middle East Carbonate Reservoirs

One of the main difficulties for modeling and producing carbonate rock oil reservoir in the Middle East is linked to the<br>fact that these reservoirs often display numerous and variable heterogeneities, ranging from plug micro-scale<br>heterogeneity (texture, pore types, cementation, ...) to field mega-scale heterogeneity (geometries and facies,<br>fracturation and faulting). Because these heterogeneities often result in significant variations in permeability and<br>saturation, and hence in productivity it is absolutely necessary to capture all of these scales of heterogeneities and<br>understand their origin. Various factors can be implied alone or combined between them: depositional environment,<br>sequence stratigraphy, early or late diagenetic overprint and fracturation scheme.
