Water-Drive Gas Reservoir: Sensitivity Analysis And Simplified Prediction, Junpeng Yue Jan 2002

Water-Drive Gas Reservoir: Sensitivity Analysis And Simplified Prediction, Junpeng Yue

LSU Master's Theses

Water influx and well completions affect recovery from water-drive gas reservoir. Material balance, aquifer models and well inflow equations are used to examine and predict the pressure depletion, water influx, and production rates of water-drive gas reservoirs. The parameters of these simple, lumped models are estimated from simulation results using response surfaces and experimental designs for eight varying geologic and engineering factors. Eleven simulated responses (including maximum gas rate, aquifer and well constants, and water breakthrough) are analyzed using ANOVA and response models. A sensitivity analysis of aquifer productivity index, gas production factor, and sweep efficiency reveals that permeability is …

Water Discharge Models, Seasonal Effluent Mass Loading, And Best Management Practices For Crawfish Ponds, Landon David Parr Jan 2002

Water Discharge Models, Seasonal Effluent Mass Loading, And Best Management Practices For Crawfish Ponds, Landon David Parr

LSU Master's Theses

Nearly 35,000 ha are used to grow crawfish in southwest and south-central Louisiana, and many of these ponds discharge into impaired water bodies. In 2002, proposed guidelines were published by the United States Environmental Protection Agency (USEPA) assigning effluent limitations and standards for some aquaculture production systems and exempting others (e.g. crawfish ponds). This research had three objectives relative to crawfish ponds: develop water discharge models; final drawdown effluent quality and seasonal mass loading of solids and nutrients; and identification of Best Management Practices (BMPs) that could reduce effluent discharge and improve effluent quality.

Modeling Adsorption Of Cane Sugar Colorant In Packed-Bed Ion Exchangers, Hugh Anthony Broadhurst

LSU Master's Theses

The removal of cane sugar solution colorant by packed-bed ion exchangers was modeled using a linear driving force (LDF) adsorption model. Adsorption of colorant is of interest to the developers of the White Sugar Mill (WSM) process as it is a complex subject. The problem is that color is an indiscrete mixture of many components making it difficult to measure and even more challenging to model. Colorant formation was investigated using gel permeation chromatography (GPC) with the objective of developing a method to define pseudo-components representative of cane sugar solution colorants. WSM is a process for producing white sugar directly …

A Correlation Between The Optical And Mechanical Properties Of Novel Polysilane/Polysiloxane Nanocomposites, Sungho Lee

LSU Master's Theses

Polysilanes are ¥ò-conjugated conductive polymers with a one-dimensional Si backbone and organic substituted side chains. The conventional Wurtz-type coupling reaction has been used for preparing various alkyl substituted polysilanes, i.e. poly(di-n-hexyl)silane and poly(hexylmethyl)silane. For each polysilane examples with methoxy (-OCH3) and allyl (-CH2CH=CH2) end caps have been prepared. The solution UV absorption characteristics of the polysilanes at room temperature have been measured, from which the wavelength maximum of the UV-VIS absorption and the absorptivity have been obtained. Allyl end capped polysilanes have the same wavelength maximum as methoxy end capped polysilanes. However, the absorptivities of allyl end capped polysilanes are …

The Radiation-Induced Degradation Of Poly(Diene Sulfones) As X-Ray Resists, Gina Marie Calderon Jan 2002

The Radiation-Induced Degradation Of Poly(Diene Sulfones) As X-Ray Resists, Gina Marie Calderon

LSU Master's Theses

The microlithographic process, essential in the fabrication of silicon chip integrated circuits, uses high-energy radiation to transfer a pattern onto a thin film of polymer resist. Pattern transfer occurs by modifying the properties (solubility or volatility) of the polymer film exposed to radiation. Poly(olefin sulfones) exhibit a high sensitivity to x-rays, which is a desirable property for polymer resists, but typically undergo a glass transition around room temperature and a thermal degradation at moderate temperatures. The thermal properties of the poly(olefin sulfones) reduce the processing latitude for industrial microelectronics applications. Poly(unsaturated olefin sulfones) containing a carbon-carbon double bond in the …

Overpressuring, Diagenesis, And Fluid Flow At The Matagorda Island 519 Field, Offshore Texas, Gulf Of Mexico, Kera Gautreau Spears Jan 2002

Overpressuring, Diagenesis, And Fluid Flow At The Matagorda Island 519 Field, Offshore Texas, Gulf Of Mexico, Kera Gautreau Spears

LSU Master's Theses

The relations between overpressuring, diagenesis, and fluid flow in sedimentary basins are complex and multifaceted. The Matagorda Island 519 field (MI 519), offshore Texas, provides an excellent area for investigating some of these relations. The top of overpressure at MI 519 occurs at a depth of 3.5 to 3.8 km in a Lower Miocene deltaic sequence. On the basis of log-derived lithostratigraphy, the pressure seal does not appear to be lithologic in origin. Geochemical, mineralogical, and cuttings information indicate instead that the precipitation of diagenetic calcite and possibly quartz cements has been the major factor in seal development. Stratigraphic variation …

Prediction Of Transient Head On Seepage Path Using Boundary Fitted Coordinate (Bfc) System, Sherly Hartono Jan 2002

Prediction Of Transient Head On Seepage Path Using Boundary Fitted Coordinate (Bfc) System, Sherly Hartono

LSU Master's Theses

One of the main causes of levee failure is seepage through levee. This seepage can cause weakening in the levee structure, which in turn can cause sudden levee failure or overtopping of the levee due to levee depression. The purpose of this study is to determine the transient head on the seepage path due to changing water level during flood period. Transient seepage problems are very important as critical condition can occur during this time rather than during steady state condition. Seepage path through a levee can be predicted using the Boundary Fitted Coordinate (BFC) system method. The physical coordinate …

Feeding Habits Of Blacktip Sharks, Carcharhinus Limbatus, And Atlantic Sharpnose Sharks, Rhizoprionodon Terraenovae, In Louisiana Coastal Waters, Kevin Patrick Barry

LSU Master's Theses

Little is known regarding the feeding behavior of many shark species. Even less is known about shark feeding habits in Louisiana coastal waters. The stomach contents of gillnet-captured blacktip sharks (n=356), Carcharhinus limbatus, and Atlantic sharpnose sharks (n=55), Rhizoprionodon terraenovae, were examined in this study. Roughly half of the blacktip stomachs (52%) and sharpnose stomachs (45%) contained prey items. The primary prey item in terms of percent number, occurrence, and weight for blacktips and sharpnose was the gulf menhaden, Brevoortia patronus. Both blacktips and sharpnose appear to mainly be piscivores; however, no members of Sciaenidae, the most common family of …

Efficient Convolvers Using The Polynomial Residue Number System Technique, Surendar Paruchuri Jan 2002

Efficient Convolvers Using The Polynomial Residue Number System Technique, Surendar Paruchuri

LSU Master's Theses

The problem of computing linear convolution is a very important one because with linear convolution we can mechanize digital filtering. The linear convolution of two N-point sequences can be computed by the cyclic convolution of the following 2N-point sequences. The original sequence padded with N zero’s each. The cyclic convolution of two N-point sequences requires multiplications and additions for its computation. A very efficient way of computing cyclic convolution of two sequences is by using the Polynomial Residue Number System (PRNS) technique. Using this technique the cyclic convolution of two N-point sequences can be computed using only N multiplications instead …

Implementation Of An Integrated Quality Assurance Program For Ct-Tps Process, Junqing Wu Jan 2002

Implementation Of An Integrated Quality Assurance Program For Ct-Tps Process, Junqing Wu

LSU Master's Theses

Systematic constancy and accuracy of a treatment planning system (TPS) are crucial for the entire radiation treatment planning process (TPP). The Quality Assurance (QA) of individual components does not necessarily lead to satisfying performance of the whole process due to the possible errors introduced by the data transfer process between components and other fluctuations. However, most of current QA for TPS is confined to the treatment planning computers. In this study, a time efficient and integrated CT-TPS QA procedure is presented, which starts at the beginning of the TPS input --- Computer Tomograhpy (CT). The whole QA procedure is based …

The Differences In Performance Of A Left Vs. Right Brained Golfer On A Curvilinear Golf Course, Robin Suzanne Jamison Jan 2002

The Differences In Performance Of A Left Vs. Right Brained Golfer On A Curvilinear Golf Course, Robin Suzanne Jamison

LSU Master's Theses

Our everyday movement is reflected by those individuals who design the world in which we live. Ninety percent of the people who shape our everyday lives are right handed. Individuals perceive life differently, especially left and right handed individuals. One reason left and right-handed individuals interpret differently is due to the brains’ two hemispheres processing information separately. Can this difference in interpretation result in varying abilities of performance? Research has proven that those individuals who are right hemisphere dominant process and comprehend shapes better than left hemisphere dominant individuals. Golf is an activity that is exhibits the constant changing of …

Nutrient Reserves Of Lesser Scaup During Spring Migration In The Mississippi Flyway: A Test Of The Spring Condition Hypothesis, Michael J. Anteau Jan 2002

Nutrient Reserves Of Lesser Scaup During Spring Migration In The Mississippi Flyway: A Test Of The Spring Condition Hypothesis, Michael J. Anteau

LSU Master's Theses

The continental scaup population (lesser [Aythya affinis] and greater scaup [A. marila] combined) has declined markedly during the past 20 years, and has remained below the population goal of the North American Waterfowl Management Plan since 1985. One hypothesis explaining the scaup population decline states that reproductive success has decreased because females presently are arriving on breeding areas in poorer condition than that historically (Spring Condition Hypothesis [SCH]). I tested the SCH by comparing fresh body masses (FBMs) and nutrient reserves (lipid, protein, and mineral) of lesser scaup at 4 locations (Louisiana, Illinois, Minnesota, and Manitoba) in the Mississippi Flyway …

Geostatistical Shale Models For A Deltaic Reservoir Analog: From 3d Gpr Data To 3d Flow Modeling, Hongmei Li

LSU Master's Theses

The effects of shales on fluid flow in marine-influenced lower delta-plain distributary channel deposits are investigated using a three-dimensional ground-penetrating radar (GPR) data volume from the Cretaceous-age Ferron sandstone at Corbula Gulch in central Utah, USA. Using interpreted GPR data, we formulate a geostatistical model of the dimensions, orientations, and geometries of the internal structure from the subaerial exposure surface down to about 12 m depth. The correlation function between GPR instantaneous amplitude and shale index is built after statistical calibration of the GPR attributes (amplitude) with well data (gamma ray logs). Shale statistics are computed from this correlation function. …
