Generalized Radial Transport Model For Interpreting Convergent Flow Tracer Tests In Fractured Rock, Md Lal Mamud Jan 2019

Generalized Radial Transport Model For Interpreting Convergent Flow Tracer Tests In Fractured Rock, Md Lal Mamud

Electronic Theses and Dissertations

The double-porosity Generalized Radial Transport (GRT) model is an extension of the generalized radial flow approach developed for hydraulic test interpretation. In both approaches, a flow dimension characterizes the change in flow area versus radial distance from the borehole. The GRT model collapses to a 1D, radial, and spherical advection dispersion equation (ADE) for integer flow dimensions of 1, 2, and 3, respectively. And, the model also transforms to sub-linear, sub-radial, sub-spherical and eventually transform to super-spherical transport model for non-integer flow dimension, n of 0 < n < 1, 1 < n < 2, 2 < n < 3 and n >3 respectively. Non-integer flow dimensions, especially sub-radial, are commonly reported from pumping tests in …


Structural Controls And Depositional Environments Of The Glen Rose Subgroup In Pelahatchie Field In Rankin County, Mississippi, Chesney Petkovsek Jan 2019

Structural Controls And Depositional Environments Of The Glen Rose Subgroup In Pelahatchie Field In Rankin County, Mississippi, Chesney Petkovsek

Electronic Theses and Dissertations

Following Lion Oil’s drilling of the Sowell #1, Lower Cretaceous step-out drilling in Pelahatchie Field has led to the establishment of Mooringsport, Paluxy, Rodessa, Sligo, and Hosston oil and gas condensate production along the flanks and crest of a salt feature within Rankin County, Mississippi. Exploration of salt features has been intermittent throughout Mississippi, but has shifted from targeting pay zones along the crests of domal and piercement salt features in the 1940s, to targeting reserves along the flanks of these features in the 1970s. The dominant structural feature in Pelahatchie Field is an elongate north-south-trending salt ridge. Results of …


Interpreting Vegetation And Soil Anomalies In The Guarumen Area Of Northwestern Venezuela Using Remote Sensing Applications, Tyler Edward Ricketts Jan 2019

Interpreting Vegetation And Soil Anomalies In The Guarumen Area Of Northwestern Venezuela Using Remote Sensing Applications, Tyler Edward Ricketts

Electronic Theses and Dissertations

The Guarumen area of Venezuela is a tectonically active region that is approximately 1,640 mi2 across the northern portions of the Barinas Basin and the foothills of the Mérida Andes. It is structurally influenced by the Caribbean plate to the north, the Nazca plate to the west, and the Maracaibo block against the Guyana Shield of the South American Plate. These result in an oblique boundary that gives rise to the fold-and-thrust belt of the Mérida Andes to the west, and the Caribbean Mountain system to the north, in concordance to the right-lateral shearing that is evidenced by the Boconó …


Detrital Zircon Provenance And Correlation Of Two Newly Discovered Ripley Formation Bentonites: Pontotoc County, Mississippi, Elizabeth Jayne Vitale Jan 2019

Detrital Zircon Provenance And Correlation Of Two Newly Discovered Ripley Formation Bentonites: Pontotoc County, Mississippi, Elizabeth Jayne Vitale

Electronic Theses and Dissertations

Two newly discovered bentonite deposits in northern and southern Pontotoc County, Mississippi occur in the Upper Cretaceous outcrop in a banded pattern on the northeastern margin of the Mississippi Embayment (MSE). The entire Ripley Formation (Fm) consists of ~73 m of fossiliferous clay, sand, and calcareous sand beds. The bentonites are located stratigraphically within the Chiwapa Sandstone Member (CSM) at the top of the Ripley Fm and stratigraphically lie above previously mined bentonites in central Pontotoc County. Since the northern and southern bentonites differ stratigraphically from the previously mined bentonites, it is possible that there are other unknown bentonite deposits …


The Medicine Hat Block And The Assembly Of Laurentia: New Interpretations From Single-Grain Zircon Analyses, Blake Oswell Ladouceur Jan 2019

The Medicine Hat Block And The Assembly Of Laurentia: New Interpretations From Single-Grain Zircon Analyses, Blake Oswell Ladouceur

Electronic Theses and Dissertations

The Medicine Hat Block (MHB) is one of the core cratonic elements that amalgamated in the Paleoproterozoic to form Laurentia. However the role of the MHB in the formation of Laurentia is poorly constrained due to virtually all of the MHB being concealed by Proterozoic and younger supracrustal sequences limiting availability of data. The primary sources of samples from the MHB are 1) xenoliths of variable metamorphic grade including gneisses amphibolites and meta-plutonic rocks collected from Eocene volcanic rock; and 2) similar lithologies recovered from boreholes that penetrate to the MHB basement. Previous work on samples from the MHB yielded …


Petrology, Provenance, And Depositional Setting Of The Lower Tallahatta Formation (Meridian Sand) In Grenada County, Mississippi, Husamaldeen Zubi Jan 2019

Petrology, Provenance, And Depositional Setting Of The Lower Tallahatta Formation (Meridian Sand) In Grenada County, Mississippi, Husamaldeen Zubi

Electronic Theses and Dissertations

The Meridian Sand represents the lowermost member of the Middle Eocene Tallahatta Formation, which is found in the Gulf Coast region of the United States. Five stratigraphic sections in Grenada County were measured and described. Twenty-one sand and sandstone samples, and 2 mud samples were collected from all sections. Textural analyses were performed on all 23 samples to determine their lithologic properties. Petrographic descriptions and modal analyses were performed on thin sections made from the 21 sand and sandstone samples, and 400 grains were point counted in each sample. Geochemical analyses were carried out on all sand, sandstone, and mud …


X-Ray Fluorescence Analysis Of Tuscaloosa Marine Shale Cuttings From Horizontally Drilled Wells, Xiaotian Wang Jan 2019

X-Ray Fluorescence Analysis Of Tuscaloosa Marine Shale Cuttings From Horizontally Drilled Wells, Xiaotian Wang

Electronic Theses and Dissertations

The Upper Cretaceous Tuscaloosa Marine Shale (TMS) is a gray to black fissile marine shale deposited at depth of between 10,000 and 20,000 ft near the ancient Gulf of Mexico. The TMS has been gradually developed as a hydrocarbon reservoir in the past several decades. But there are rare researches evaluating geochemical properties based on chemostratigraphy of the TMS. The objective of this research is to spatially evaluate geophysical properties and chemostratigraphy of the TMS, to characterize elemental changes along well paths and to evaluate the effect of basic sample clean on XRF results. The data available for this study …
