Application Of Computational Fluid Dynamics To Near-Wellbore Modeling Of A Gas Well, Oscar Mauricio Molina
Application Of Computational Fluid Dynamics To Near-Wellbore Modeling Of A Gas Well, Oscar Mauricio Molina
LSU Master's Theses
Well completion plays a key role in the economically viable production of hydrocarbons from a reservoir. Therefore, it is of high importance for the production engineer to have as many tools available that aid in the successful design of a proper completion scheme, depending on the type of formation rock, reservoir fluid properties and forecasting of production rates. Because well completion jobs are expensive, most of the completed wells are usually expected to produce as much hydrocarbon and as fast as possible, in order to shorten the time of return of the investment. This research study focused on the evaluation …
Field And Numerical Investigation Of Wave Power And Shoreline Retreat In Terrebonne Bay, Southern Louisiana, Kyle Ryan Parker
Field And Numerical Investigation Of Wave Power And Shoreline Retreat In Terrebonne Bay, Southern Louisiana, Kyle Ryan Parker
LSU Master's Theses
The marshland in southern Louisiana is a vital resource that many people and wildlife depend on. Terrebonne Bay was chosen for this research because it has experienced one of the largest wetland loss rates among Louisiana estuaries. Investigations of wave power and shoreline retreat rate could provide decision makers with a better understanding of the contributing wave force responsible for local shoreline retreat. A strong relationship has been shown to exist between wave power and shoreline retreat [Schwimmer (2001) and Marani et al. (2011)]. Whether or not this strong relationship exists in Terrebonne Bay is the subject of this research. …
Shear Strength Evaluation Of An Erosional Soil System At Fourchon Beach, Jacques Pierre Boudreaux
Shear Strength Evaluation Of An Erosional Soil System At Fourchon Beach, Jacques Pierre Boudreaux
LSU Master's Theses
South Louisiana is vanishing. Subsidence due to relative sea level rise with erosion of weak wetland soils together produce devastating rates of land loss for this area. It is believed that high rates of erosion are due to weak strength properties of fine-grained sediments in the beaches, marshes, and other wetlands in coastal Louisiana. Wave action is known to initiate the movement of weak coastal soils in a manner that is related to the difference between the shear stresses applied by waves and the critical shear strength of erosional sediments. Direct shear tests were performed on samples obtained from the …
Determining The Performance Of Breakwaters During High Energy Events: A Case Study Of The Holly Beach Breakwater System, Andrew Keane Woodroof
Determining The Performance Of Breakwaters During High Energy Events: A Case Study Of The Holly Beach Breakwater System, Andrew Keane Woodroof
LSU Master's Theses
Breakwaters have been constructed in many areas along Louisiana’s coastline to protect the shoreline from wave energy and erosion. During normal conditions, these breakwaters can typically be analyzed using traditional empirical methods for emergent breakwaters. However, Louisiana’s coastline is under constant threat from tropical storms and hurricanes, during which breakwaters can frequently become overtopped or submerged systems. Recent studies show that the type of shoreline response to a breakwater system may vary depending on the crest height of the breakwater in relation to the mean water level. Though emergent breakwaters typically induce sediment accretion along the shoreline, studies using laboratory …
Analysis And Evaluation Of A Bioengineered Submerged Breakwater, Matthew Dwain Campbell
Analysis And Evaluation Of A Bioengineered Submerged Breakwater, Matthew Dwain Campbell
LSU Master's Theses
Louisiana's coastline has received national attention due to rapid erosion rates estimated from approximately 60 to 100 square kilometers per year. The disappearance of coastal areas jeopardizes public and private infrastructure, property values, aquatic ecosystems, and standards of living. In order to resolve the erosion problem, innovative solutions have been explored that may improve effectiveness and cost efficiency. This research involves a technology, termed an "oysterbreak," which is a bioengineered submerged breakwater. This structure promotes oysters to form a dense structure that dissipates wave energy. Since the structure is biologically dominated, initial material use is modest. The oysterbreak was evaluated …
