Analysis Of Crush Resistance And Mississippi-Sourced Sands To Determine Potential As Proppant Sands, Ryann C. Lam Jan 2019

Analysis Of Crush Resistance And Mississippi-Sourced Sands To Determine Potential As Proppant Sands, Ryann C. Lam

Honors Theses

Proppant is a media used in hydraulic fracturing to bear in-situ stresses in order to maintain fracture networks, which act as highly permeable pathways for hydrocarbon recovery. Proppant can be made from a variety of materials such as glass, ceramic beads, sand particles, and more. Proppants are characterized by their size, sorting, roundness, and sphericity. These properties help determine the compressive strength of the pack proppant. This study focuses on these properties for natural sand. The purpose of this study is to evaluate the viability of lower-quality sands as proppant sands by testing the affect these properties have on the ...


A Comparative Case Study Of Reflection Seismic Imaging Method, Moones Alamooti Jan 2018

A Comparative Case Study Of Reflection Seismic Imaging Method, Moones Alamooti

Electronic Theses and Dissertations

Reflection seismology is the most common and effective method to gather information on the earth interior. The quality of seismic images is highly variable depending on the complexity of the underground and on how seismic data are acquired and processed. One of the crucial steps in this process, especially in layered sequences with complicated structure, is the time and/or depth migration of seismic data. The primary purpose of the migration is to increase the spatial resolution of seismic images by repositioning the recorded seismic signal back to its original point of reflection in time/space, which enhances information about ...

Comparing The Depositional Environments Of The Upper Smackover Formation In Southwestern Clarke County, Mississippi And Brooklyn/ Little Cedar Creek Field, Alabama, Elsie Ekene Okoye

Electronic Theses and Dissertations

This research evaluated the depositional settings of the upper Smackover formation in southwestern Clarke County (scc), Mississippi and compared its facies to those of the Brooklyn and little cedar creek fields (bf/lcc) in Conecuh and Escambia Counties, Alabama. The Smackover formation has been a prolific oil producing formation in the Gulf of Mexico since its discovery in Union County, Arkansas in 1937. The discovery of the lcc in 1994 and the bf in 2007 has generated additional interest in the Smackover. The bf/ lcc occur near the updip limit of the upper Jurassic (Oxfordian) Smackover formation. These fields produce ...


Acoustic Behavior Of Soil Reinforced With Grass Roots, Blake Armstrong Jan 2016

Acoustic Behavior Of Soil Reinforced With Grass Roots, Blake Armstrong

Electronic Theses and Dissertations

Civil engineering practice has shown that vegetative roots on slopes and streambanks can substantially increase shear strength of soil and reduce erosion. Research has been done to understand and quantify the effect. Most studies have been conducted on slopes and streambanks with woody vegetation. Past research has used a perpendicular root model to predict increase in cohesion, or shear strength, due to the mobilization of roots' tensile strength. Acoustics can be used to monitor internal changes of soil by interacting with soil particles and interstitial fluids. Compressional wave, or p-wave, velocity can be used to predict changes in effective stress ...


Reconstructing Lithofacies Of The Norphlet Formation (Jurassic) As Potential Exploration Targets: Little Cedar Creek And Brooklyn Fields, Southwest Alabama, Catherine E. Henry Jan 2016

Reconstructing Lithofacies Of The Norphlet Formation (Jurassic) As Potential Exploration Targets: Little Cedar Creek And Brooklyn Fields, Southwest Alabama, Catherine E. Henry

Electronic Theses and Dissertations

The Norphlet Formation is a Jurassic-aged siliciclastic unit located across the southeastern United States and offshore Gulf of Mexico. The eolian dune sands present in the Norphlet Formation serve as oil and gas reservoirs, making the formation of particular interest to oil and gas companies. Stable Appalachian ridges are the source of the Norphlet Formation, however deposition is related to complex faults and structures resulting from movement of the Louann Salt. Erosion of the ancestral Appalachian Mountains resulted in the deposition of four main lithofacies: basal shales, conglomerates and conglomeratic sandstones, the Denkman Sandstone member, and a redbed succession. Additionally ...

Modeling Roughness Of Rock Discontinuity Surfaces, Christopher Pickering Jan 2015

Modeling Roughness Of Rock Discontinuity Surfaces, Christopher Pickering

Electronic Theses and Dissertations

The aim of this thesis is to propose a new methodology of quantifying the rock discontinuity condition of roughness through the physically based modeling approach of signal analysis. The development of this method came about after investigation into the use of qualitative categorizations of roughness from the RMR rating system within rock engineering system matrices. In an attempt to assign significant values to these generalized qualitative descriptions, the standard joint roughness coefficient (JRC) profiles were initially examined through basic measurements, such as aperture and ramp angle. Following these initial measurements and identification of inconsistencies in the wave parameters of the ...


Subsurface Discontinuity Analysis & Modeling For The Federal Waste Disposal Facility And Compact Waste Disposal Facility Landfills, Shuang Cao Jan 2013

Subsurface Discontinuity Analysis & Modeling For The Federal Waste Disposal Facility And Compact Waste Disposal Facility Landfills, Shuang Cao

Electronic Theses and Dissertations

This research considers discontinuities mapped by Waste Control Specialists LLC to support the site conditions and performance analysis of the Compact Waste Disposal Facility and the Federal Waste Disposal Facility excavations constructed near Andrews, Texas. Discontinuities observed in excavation walls contain a limited number of discontinuities showed evidence of previous fluid movement. While no networks of such discontinuities were observed in the field, the potential for such networks may exist. This research is significant in understanding the performance of these waste facilities by modeling multiple realizations of possible fracture configurations in three-dimensional spatial models of the type of discontinuities observed ...


Influence Of Capillary Heterogeneity On Leakage Of Co2 From A Borehols, Frank Roecker Jan 2012

Influence Of Capillary Heterogeneity On Leakage Of Co2 From A Borehols, Frank Roecker

Electronic Theses and Dissertations

We used a modified invasion percolation (MIP) model to examine the effect of capillary heterogeneity, buoyancy forces, and viscous forces on the surface area and saturation of a CO2 plume leaking into a shallow aquifer. The purpose of this study is to provide a better understanding of how CO 2 migrates from a borehole, which is essential in implementing effective simulation and monitoring regimes to accurately detect CO2 leakage from sequestration sites. The MIP model approach will simulate invasion of a light non-wetting fluid (e.g., CO2) into a medium initially saturated with a dense wetting fluid (water). The style ...

A Field Validation Of Dam Indexing Methods In Mississippi, Steven Thomas Fox Jan 2011

A Field Validation Of Dam Indexing Methods In Mississippi, Steven Thomas Fox

Electronic Theses and Dissertations

Indexing methods are applied to dam inventories throughout the United States to assist in prioritizing resources to maintain aging dam structures. Three published indexing methods and one proposed method were applied to 24 dams through Mississippi. The majority of dams in Mississippi have little to no information concerning the performance records or design specifics of a given dam. Field assessments were conducted to determine the physical condition of each dam, identify potentially deficiencies at dams, and calculate a consequence in the event of a dam failure. The results of the four indexing methods will be compared and advantages and disadvantages ...
