| Summary: | Pressure transient analysis could provide valuable information on the characterization and evaluation of reservoir. Previous studies have shown critical analysis of injection and falloff tests of water or gas injection wells. Existing pressure transient study conducted on immiscible water-alternating-gas (IWAG) injection wells mainly focused on falloff test without considering the presence of skin near the wellbore region. The objective of this study is to analyze the pressure transient behavior of IWAG injection and falloff test with and without skin effect using simulated data. Presence of skin near the wellbore region could adversely affect the pressure behavior of reservoir. Likewise, the pressure transient behavior will provide useful information in reservoir characterization study. ECLIPSE 100 is used to simulate the reservoir model under different mobility condition with the presence of skin for a water-oil system only since gas-oil system is always unfavorable. |
