Demonstration And Performance Characterization Of The Gas Assisted Gravity Drainage (Gagd) Process Using A Visual Method, Thaer N.N. Mahmoud
Demonstration And Performance Characterization Of The Gas Assisted Gravity Drainage (Gagd) Process Using A Visual Method, Thaer N.N. Mahmoud
LSU Master's Theses
The Gas Assisted Gravity Drainage (GAGD) process, currently being developed at LSU, is designed to take advantage of gravity to allow vertical segregation between the injected gas and reservoir crud oil due to their density differences. GAGD is recommended for use with CO2 gas. CO2 dissolves in oil and causes both swelling and viscosity reduction of oil. The GAGD process uses the existing vertical wells for CO2 gas injection, and a horizontal well near the bottom of the payzone for oil production. GAGD, as an EOR process, is not restricted to tertiary oil recovery only. In this research study, a …
Physical Model Study Of The Effects Of Wettability And Fractures On Gas Assisted Gravity Drainage (Gagd) Performance, Wagirin Ruiz Paidin
Physical Model Study Of The Effects Of Wettability And Fractures On Gas Assisted Gravity Drainage (Gagd) Performance, Wagirin Ruiz Paidin
LSU Master's Theses
The Gas-Assisted Gravity Drainage (GAGD) process was developed to take advantage of the natural segregation of injected gas from crude oil in the reservoir. It consists of placing a horizontal producer near the bottom of the reservoir and injecting gas using existing vertical wells. As the injected gas rises to the top to form a gas cap, oil and water drain down to the horizontal producer. Earlier experimental work using a physical model by Sharma had demonstrated the effectiveness of the GAGD process in improving the oil recovery when applied in water-wet porous media. The current research is an extension …
Hydrate Dissociation During Drilling Through In-Situ Hydrate Formations, Erdem Catak
Hydrate Dissociation During Drilling Through In-Situ Hydrate Formations, Erdem Catak
LSU Master's Theses
Natural gas hydrates are thought to be the future hydrocarbon source of the energy hungry world. Tremendous amount of research has been done to investigate the feasibility of gas production from the hydrate formations. In this direction, three basic production methods, thermal stimulation, depressurization and thermodynamic inhibitor injection have been proposed to produce hydrocarbons off the hydrates. On the other hand, they present high potential risk of drilling hazards, such as severe gasification of drilling fluid, casing collapse due to increase in pressure after dissociation of hydrate zone, and instability of ocean floor, which may cause a platform failure. Scientists …
Compositional Effects On Gas-Oil Interfacial Tension And Miscibility At Reservoir Conditions, Daryl Sean Sequeira
Compositional Effects On Gas-Oil Interfacial Tension And Miscibility At Reservoir Conditions, Daryl Sean Sequeira
LSU Master's Theses
Minimum miscibility pressure (MMP) is an important optimization parameter for an enhanced oil recovery process involving Carbon Dioxide or hydrocarbon gas injection. Therefore an accurate experimental measurement is required to determine the MMP. The MMP for a gas-oil system is directly related to the interfacial tension between the injected gas and the reservoir crude oil. When CO2 gas contacts the reservoir oil at reservoir temperature, the interfacial tension between the fluid-fluid phases reduces as the miscibility is approached and the interface between the fluid-fluid phases eventually disappears at miscibility i.e. the interfacial tension becomes zero. Hence, a pressure condition of …
Feasibility Of Supercritical Carbon Dioxide As A Drilling Fluid For Deep Underbalanced Drilling Operations, Anamika Gupta
Feasibility Of Supercritical Carbon Dioxide As A Drilling Fluid For Deep Underbalanced Drilling Operations, Anamika Gupta
LSU Master's Theses
Feasibility of drilling with supercritical carbon dioxide to serve the needs of deep underbalanced drilling operations has been analyzed. A case study involving underbalanced drilling to access a depleted gas reservoir is used to illustrate the need for such a research. For this well, nitrogen was initially considered as the drilling fluid. Dry nitrogen, due to its low density, was unable to generate sufficient torque in the downhole motor. The mixture of nitrogen and water, stabilized as foam generated sufficient torque but made it difficult to maintain underbalanced conditions. This diminished the intended benefit of using nitrogen as the drilling …
