... treatments in reservoirs with two layers of different permeability but the same initial skin factor and with the same permeability but very different skin factor. MAPDIR reduces overall skin factor fastest but at the cost of injection of large volumes of acid into the higher-injectivity layer. Particulate...

... will be presented to illustrate these effects. Ignoring these effects can lead to the wrong pressure transient analysis. gauge buildup drillstem/well testing initial pressure anomaly pressure transient analysis falloff injection reservoir recorder wellbore dynamic interpretation reservoir pressure...

... geostatistical to conventional reservoir descriptions. Assess uncertainty of reservoir performance (cumulative oil production, oil production rate, and water-oil ratio) for primary, secondary and tertiary production. injection oil production rate tomographic data north cowden unit crosswell...

... comparative analysis enabled the identification of the main reservoir/fluid parameters that have an impact on the success of EOR methods. Analysis was done on EOR methods such as steam injection, polymer flooding, surfactant flooding, group of the gas injection methods, and CO 2 -flooding. The data base...
