Design Of A Conditioner For Smoothing Wind Turbine Output Power, Murali Bottu, Mariesa Crow, A. Curt Elmore
Design Of A Conditioner For Smoothing Wind Turbine Output Power, Murali Bottu, Mariesa Crow, A. Curt Elmore
Electrical and Computer Engineering Faculty Research & Creative Works
As a result of wind speed intermittency, highly variable wind power output can adversely impact local loads. We propose a conditioner to smooth the variable wind power by utilizing the energy of an ultracapacitor. The conditioner is based on a single phase voltage source inverter (VSI) connected between the grid interconnection point and the ultracapacitor. The shunt VSI injects or absorbs active power from the line to smooth the wind power by utilizing the short term storage capabilities of the ultracapacitor. The ultracapacitor is connected to the DC link through a DC-DC converter, which maintains the voltage of the DC …

Theses
In this thesis, the modeling and simulation of the absorption of dilute CO2 into falling film of aqueous solutions of a sterically hindered amine, 2-anino-2-methyl-1-propanol (AMP), was carried out using COMSOL Multiphysics Version 3.3. The operating cases were divided in two groups: (1) gas turbine operating cases (CO2 3 mol %) and (II) boiler operating cases (CO2 8.5 mol %). The key operating parameters for the studied cases are CO2 partial pressure, operating temperature and amine concentration in the aqueous solution. The simulation focused on the following: (1) CO2 Loading in aqueous AMP solution; (2) …

History Of Petroleum Engineering At Montana Tech, Leo Heath, Debbie Todd
Petroleum Engineering
In January, 2010, the Petroleum Engineering department at Montana Tech moved into a new building, the Natural Resources Building, to start a new chapter in the history of the program on campus. Occupying a new building is a positive event, and it coincides with a surge of student enrollment which is prompted by industry needs and world energy demand. This time of new facilities and growing student numbers leads to the question of what the future has in store for the department. It also leads to reflection about where the department has been in the past. This history is a …

Storage of CO2 in saline aquifers is a viable option for reducing the amount of CO2 released to the atmosphere. This paper provides an overall review of CO2 sequestration in saline aquifers. First, the principles of CO2 sequestration are presented, including CO2 phase behavior, CO2-water-rock interaction, and CO2 trapping mechanisms. Then storage capacity and CO2 injectivity are discussed as the main determinants of the storage potential of saline aquifers. Next, a site section process is addressed considering basin characteristics, reservoir characteristics, and economic and social concerns. Three main procedures are then …

At present, water-Based fracturing fluid systems are mainly polymer (macromolecule) and visco-elastic surfactant (micro molecule). Because of polymer properties and incomplete gelout, the damage to matrices and conductivity of artificial fractures will be inevitable. the surfactant-Based fracturing fluid system is a micro-molecule system not to damage artificial fractures. However, it is difficult to eliminate the damages from rock debris moving and clay swelling information. a novel free-damage fracturing fluid system (FDFF), a cationic surfactant derived from a long chain fatty acid, has been developed and applied in Daqing oil field. FDFF can crosslink in a wide range from a strong …

We present Alkyl polyglycoside (APG)/1-naphthol formulations which show ultra-low interfacial tensions (IFT) against n-octane. We demonstrate that 1-naphthol is very efficient as a cosolvent in terms of reducing IFT. These formulations are therefore potentially suitable as agents for enhanced oil recovery (EOR). an increasing APG concentration strongly increased viscosity, and the formulations showed shear-thinning behavior. in a core flood EOR test we showed that this type of formulation significantly increased oil production. © 2010, European Association of Geoscientists and Engineers.
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 …
Strength Evaluation And Transportation Behavior Of Preformed Particle Gel Using Screens And Tubes, Rajesh Sarma Challa
Strength Evaluation And Transportation Behavior Of Preformed Particle Gel Using Screens And Tubes, Rajesh Sarma Challa
Masters Theses
"This research included a series of experiments, using screen models to evaluate the strength of swollen gel particles. It also includes the study of PPG propagation and extrusion behavior through tubes of various internal diameters. The effect of the particle gel swelling ratio (depending on brine concentration), flow rate; and mesh size on the gel injection pressure and injectivity were studied. The results show that gel injection pressure depends primarily on the swelling ratio and the mesh size. However, the injection pressure does not increase significantly with injection rates, behavior consistent with the real-time injection pressure and injection rate change …

An Experimental Study Of Surfactant Enhanced Waterflooding, Paulina Metili Mwangi
LSU Master's Theses
Surfactants have a variety of applications in the petroleum industry due to their remarkable ability to lower the oil-water interfacial tension and alter wettability. However, surfactant adsorption on rock surfaces has severely crippled this means of improving oil recovery due to the high cost associated with the large quantities of surfactant needed. A previous experimental study by Ayirala (2002) reported the development of mixed wettability using a nonionic surfactant. At this mixed-wet state he was able to recover about 94% of the original oil in place. The underlying motivation of this study was to achieve such high recoveries without using …

LSU Master's Theses
Carbon capture and storage is one of the technologies that could help reduce CO2 concentration in the atmosphere while contributing to cutback of Greenhouse Gas emissions. Depleted oil and gas fields are favorable targets for CO2 storage because existing wells can be readily used as injection wells. However, a number of abandoned wells also serve as gateway to the reservoir which should be considered in the context of effective Carbon capture and storage. Wellbore cement is a very essential element in wellbore systems that serve as a barrier between different zones in the subsurface. The fractures inside wellbore cement sheath, …

Surfactant-Induced Flow Behavior Effects In Gas Condensate Reservoirs, Bikash Deep. Saikia
LSU Master's Theses
Natural gas, which accounts for a quarter of world’s energy, has been a major energy source because of its abundance and less impact on environment. With explorations at higher depth, pressure and temperature, the share of gas condensate reservoirs to global gas production is increasing. A unique production challenge associated with these reservoirs is the condensate blockage problem, which is the buildup of condensate liquid saturation around wellbore as a result of drawdown below dew point pressure. Mitigation of this problem requires in depth understanding of the multiphase flow of liquid and gas. Surfactants are well known in the literature …
A Simulation Study Of Factors That Affect Pressure Control During Kick Circulation In Managed Pressure Drilling Operations, Jose Eduardo Eduardo Chirinos
A Simulation Study Of Factors That Affect Pressure Control During Kick Circulation In Managed Pressure Drilling Operations, Jose Eduardo Eduardo Chirinos
LSU Master's Theses
An university-industry consortium has been studying alternative well control procedures to be used for kicks taken during managed pressure drilling (MPD) operations using the constant bottom hole pressure (CBHP) method. The CBHP method of MPD allows more precise control of wellbore pressure than conventional drilling. MPD surface equipment allows more alternatives for controlling a kick and may support faster detection of kicks and losses which can reduce the severity of a well control event. Nevertheless, the elimination of well control incidents cannot be guaranteed, and the uncertainty in downhole drilling margins are not reduced by adopting MPD methods. The primary …
