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 …

Pore-Scale And Conventional Wettability Measurement Considerations For Improving Certainty Of Geological Co2 Sequestration, Mohammad Jafari
Pore-Scale And Conventional Wettability Measurement Considerations For Improving Certainty Of Geological Co2 Sequestration, Mohammad Jafari
LSU Doctoral Dissertations
Parallel to the approach of developing zero-carbon-emission energies, other solutions have been recently proposed to decrease the amount of CO2 emissions into the atmosphere. Geological CO2 sequestration (GCS) has provided economic benefits and slight adverse environmental effects. GCS involves capturing CO2 from large producers, then injecting it into deep layers of the earth’s subsurface to be stored for hundreds to thousands of years. A safe and economic GCS requires a profound knowledge of immiscible CO2-water/brine fluid flow in CO2 storage sites including capillary pressure which has a barrier effect against leakage. The main uncertainty in measuring capillary pressure is due …
