The Impact of Uncertain Centrifuge Capillary Pressure on Reservoir Simulation

A Fully Integrated Method for Dynamic Rock Type Characterization Development in One of Iranian Off-Shore Oil Reservoir

Rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (SCAL). The challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (SCAL defined) in the re...

Immiscible Gas Injection to Improve Recovery from an Iranian Naturally Fractured Reservoir: a Case Study with Emphasis on Uncertain Parameters

A Capillary Pressure Function for Interpretation of Core-Scale Displacement Experiments

A capillary pressure function is proposed for interpreting core-scale flow experiments. This function has been found suitable for a wide range of rock/fluid systems with different pore geometry and wettability characteristics. The petrophysical controls are reflected in the asymptotic values relating to irreducible saturation, and threshold capillary pressure, and in the shape parameters relati...

The Impact of Reservoir Confining Stress on Nmr T2 and Pore Frequency Distribution in Some Carbonate Samples

Recent developments allow high-pressure mercury intrusion experiments to be performed under reservoir-representative confining stress. NMR relaxation measurements on core samples are increasingly being used in addition to mercury intrusion data since the two techniques yield complementary information about the pore network. Integration of the different measurement techniques result in a more de...

Sensitivity Analysis of Cumulative Oil Production and Production Rate on Block Heights and Capillary Continuity for an Iranian Carbonated Fractured Reservoir

Block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. In this study, the influence of these parameters upon cumulative production and recovery factor of an Iranian fractured reservoir were studied by the usage of a sim...
