Abstract
H024 Pore Level Investigation of Oil Depressurisation in Pores with Different Wettbility – Critical Gas Saturation K. Shahabi Nejad* (Hydro O&E) & D. Tehrani (Heriot-Watt University) SUMMARY We have conducted a series of flow visualisation tests at the pore level using high-pressure glass micromodel to identify the key features of the depressurisation process. A series of experiments were conducted to investigate the effect of fluid properties depletion rate saturation conditions wettability and saturation history on the depressurisation process. This paper presents the experimental results of this research on gas evolution critical gas saturation and hydrocarbon movement. Our observation highlighted the
