Investigation Of Flow Mechanisms In Gas-Assisted Gravity Drainage Process, Iskandar Dzulkarnain
Investigation Of Flow Mechanisms In Gas-Assisted Gravity Drainage Process, Iskandar Dzulkarnain
LSU Doctoral Dissertations
In this study we investigate displacement mechanism for oil recovered using Gas- Assisted Gravity Drainage (GAGD) method. For a typical oil recovery under gravity drainage, the recovery profile can be characterized by an initial bulk flow which occurs rapidly and a later film flow that extends for a longer duration. It is the latter period where film spreading, the ability of oil to spread above water in the presence of gas, is identified as the displacement mechanism responsible for recovering the remaining oil in gravity drainage process. Literature survey indicates that mathematical models for gravity drainage do not account for …

Characterization Of Rock/Fluids Interactions At Reservoir Conditions, Dayanand Saini
Characterization Of Rock/Fluids Interactions At Reservoir Conditions, Dayanand Saini
LSU Doctoral Dissertations
In this study, interfacial phenomena of spreading, wettability, and rock/oil adhesion interactions in complex rock/oil/water systems were characterized at reservoir conditions of elevated pressures and temperatures. Capabilities of both ambient and reservoir condition optical cells were used for measuring the oil/water interfacial tension and dynamic (the water-receding and the water-advancing) contact angles for various complex rock/oil/water systems. Well known sessile oil drop volume alteration method was successfully used in this study for evaluating the applicability of the modified Young’s equation for characterizing the line tension in complex rock/oil/water systems at reservoir conditions. This appears to be first time when rock/fluids …
