Systematics, Diversity, And Origins Of Upper Cretaceous Continental Molluscan Fauna In The Infra- And Intertrappean Strata Of The Deccan Plateau, Central India, Marron J. Bingle-Davis Jan 2012

Systematics, Diversity, And Origins Of Upper Cretaceous Continental Molluscan Fauna In The Infra- And Intertrappean Strata Of The Deccan Plateau, Central India, Marron J. Bingle-Davis

Theses and Dissertations

The Deccan Plateau in western and central India has been a major area of interest for researchers since the 1800s. In 1840, James Sowerby described the molluscan collection sent to him by John Malcolmson. In 1860, Stephen Hislop identified new molluscan species and redescribed based on better preserved material. Although this seminal work was comprehensive, interpretations have changed since the mid 1800s. Species need to be reassigned to current and/or accurate taxa, as well as revalidated statistically. Seventeen character traits were measured on over 600 specimens from five eastern Deccan Plateau localities representing a stratigraphic and temporal sequence. Cluster analysis …


Terrestrial Heat Flow And An Assessment Of Enhanced Geothermal System Resources In Minnesota, Robert Carl Lloyd Klenner Jan 2012

Terrestrial Heat Flow And An Assessment Of Enhanced Geothermal System Resources In Minnesota, Robert Carl Lloyd Klenner

Theses and Dissertations

Low heat flow has been previously reported in Minnesota (406 mW m-2) and the Superior Province of the Canadian Shield (42 ± 8 mW m-2). Low heat flow in Minnesota is due to heat flow measurements made in the mafic rocks of the Mid-Continent Rift System (MCRS) and attributed to the lack of correction for post-glacial climate fluctuations. Radioactivity is a critical heat flow component, particularly in Minnesota where all published heat flow sites are located within the MCRS, creating a bias in the data. The rift is a massive mafic intrusive complex that extends from Moho to the surface, …


Diagenesis Of The Middle Member Of The Bakken Formation, Williston Basin, North Dakota, Katharine L. Kimber Jan 2012

Diagenesis Of The Middle Member Of The Bakken Formation, Williston Basin, North Dakota, Katharine L. Kimber

Theses and Dissertations

The shales of the Bakken Formation have been extensively studied since the discovery of oil, but little attention has been paid to the middle reservoir member. Successfully produced wells are concentrated in multiple fields throughout the Williston Basin, there has been no definitive way to determine a well’s potential productivity. This study used core samples, point counting, and petrography to determine the diagenetic traits common to the Middle Member of the Bakken Formation and their effect on oil production. Cores from forty-one wells were examined. Thin sections were made from sixteen cores, eight producing wells and eight dry wells. All …


Study On Underground Coal Gasification Combined Cycle Coupled With On-Site Carbon Capture And Storage, Peng Pei Jan 2012

Study On Underground Coal Gasification Combined Cycle Coupled With On-Site Carbon Capture And Storage, Peng Pei

Theses and Dissertations

The North Dakota portion of the Williston basin holds huge, but economically unmineable lignite resources in the Fort Union formation. A technology coupling the underground coal gasification with carbon capture and storage (UCG-CCS) is proposed in this study to recover these lignite resources in North Dakota. The UCG-CCS system provides a cost-effective and environment-friendly approach to convert the lignite to electricity and beneficially utilize the by-product of CO2 at the same time. The target coal seam is the Harmon lignite in the Fort Union formation in western North Dakota. The main objectives of this study are to set up the …

Developing A Remote Sensing Algorithm For Deriving Soil Moisture From Spectral Reflectance, Santosh Rijal May 2011

Developing A Remote Sensing Algorithm For Deriving Soil Moisture From Spectral Reflectance, Santosh Rijal

Theses and Dissertations

Wet weather cycle since 1993 has brought ground water level closer to the surface of the soil in many areas in the Red River Valley (RRV) of the North basin. Many farmers have to delay spring plantation or autumn harvest due to excessive moisture in', their farmland. In such case, it becomes increasingly important to have timely and accurate information on the soil moisture conditions. Conventional soil moisture measurement techniques are point-based that results in poor spatial representation of soil moisture. Remote sensing techniques offer many potential advantages over traditional means such as repetitive coverage and areal representation. The objective …


Using Temperature Profiles To Investigate The Hyporheic Zone In An Agricultural Drainage Ditch, Richard A. Suggs Jan 2011

Using Temperature Profiles To Investigate The Hyporheic Zone In An Agricultural Drainage Ditch, Richard A. Suggs

Theses and Dissertations

During the last three decades, there has been much research on ground water/surface water interaction and hyporheic zone processes in natural rivers and streams. Research into natural systems has revealed significant ground water/surface water interaction and a complex variability that depends primarily on surface conditions, subsurface composition, and seasonal influences. Hyporheic zone interaction is an important factor contributing to water quality of both surface water and ground water systems.

This research expands on the concept of using heat transport, as revealed by temperature variation, as an analogue for water movement within a surface water/ground water system to include the man-made …


Geomechanical Stability Analysis For Co2 Sequestration In Carbonate Formation, Xue J. Zhou Jan 2011

Geomechanical Stability Analysis For Co2 Sequestration In Carbonate Formation, Xue J. Zhou

Theses and Dissertations

Geomechanical analysis is one of the fundamental pillars to build up the confidence of geological sequestration of CO2. Large scale CO2 sequestration in deep carbonate formation is a complicated geological process, which will non-reversibly transform the presumed equivalent and stable status of a sedimentary basin that formed over millions of years: chemically, hydraulically, geothermally, and geomechanically. In this dissertation, thermoporoelasticity guides the theoretical establishment of a conservative baseline for the geomechanical stability analysis of CO2 sequestration.

Extensive laboratory tests, including CO2 flooding tests, permeability tests, uniaxial and triaxial tests, Brazilian tensile strength tests, poroelasticity tests, point load tests, and fracture …


Stratigraphy And Petroleum Production Potential Of The Spearfish Formation In North Central North Dakota, Nnaemeka C. Anyanwu Jan 2011

Stratigraphy And Petroleum Production Potential Of The Spearfish Formation In North Central North Dakota, Nnaemeka C. Anyanwu

Theses and Dissertations

The Spearfish oil play is unconventional requiring the use of horizontal wells that are fracture stimulated to deliver economic flow rates. However, fraccing into the underlying water has been a source of significant production problems for operators. The key to developing the area is to keep the individual fracs large enough to stimulate the tight Spearfish sands but not to let them propagate into the underlying water zone.

The Spearfish Formation of the Black Hills has been traced into the subsurface of the Williston Basin in western North Dakota from bore holes at the northern margin of the outcrop area …


Identifying Potential Geothermal Resources From Co-Produced Fluids Using Existing Data From Drilling Logs : Williston, North Dakota, Anna M. Crowell Jan 2011

Identifying Potential Geothermal Resources From Co-Produced Fluids Using Existing Data From Drilling Logs : Williston, North Dakota, Anna M. Crowell

Theses and Dissertations

With the current need for technology that will allow for environmentally-friendly power generation, geothermal power has become an attractive resource given its low environmental impact and potential cost savings. One specific resource is co-produced water from oil wells that are not currently producing, but can yield formation waters that are both high enough in temperature and fluid volume to operate the turbines of binary geothermal power systems. The data required to identify sites, i.e. bottom-hole temperatures (BHT), latitude, longitude, total depth of hole (TD) in meters, the identification number, and the amount of water produced in gallons, can be mined …

Solar Variability And Climate Processes: The Influence Of Fluctuating Solar Spectral Irradiance On Differential Surface Heating As A Function Of Soil Geochemistry And Radiation Absorption Characteristics, Susan Wahl Aug 2009

Solar Variability And Climate Processes: The Influence Of Fluctuating Solar Spectral Irradiance On Differential Surface Heating As A Function Of Soil Geochemistry And Radiation Absorption Characteristics, Susan Wahl

Theses and Dissertations

The influence of solar variability on climate has received increasing attention. Much of the research has dealt with fluctuating ultraviolet radiation and its effects in the stratosphere; decadal signatures in cloud cover and their relationship to cosmic rays; and correlations of surface air temperature with various proxies (e.g., sunspot numbers; 10Be from ice cores and marine sediments). Much of the research has focused on changing solar radiation within the upper atmosphere and the propagating effects into the troposphere. However, there is a missing component involving differential surface heating as a function of soil composition and corresponding spectral radiation absorption properties …

Predicting The Effect Of Wetland Restoration On Phosphorus Retention, Northwest Minnesota, Ryan J. Whittaker Jan 2009

Predicting The Effect Of Wetland Restoration On Phosphorus Retention, Northwest Minnesota, Ryan J. Whittaker

Theses and Dissertations

Water quality in the Red River Valley and downstream in Lake Winnipeg has been diminishing due to excess nutrients from agriculture. One method to reduce nutrient loading to surface water is to create or restore wetlands in agricultural areas that drain cropped fields. It is commonly believed that wetlands improve water quality, but research has shown that restoring wetlands can actually release phosphorus (P) into solution. Reducing conditions caused by soil flooding can release Fe-bound P, since ferrous Fe is more soluble than ferric Fe. Little is known concerning how the soils in the Red River Valley will be affected …


Carbon Dioxide Flooding Induced Geochemical Changes In A Saline Carbonate Aquifer, Alyssa Boock Jan 2009

Carbon Dioxide Flooding Induced Geochemical Changes In A Saline Carbonate Aquifer, Alyssa Boock

Theses and Dissertations

Carbon dioxide (CO2) has been injected into depleted oil reservoirs for enhanced oil recovery for several decades. Injection of CO2 into geologic formations in the Williston Basin is currently under consideration for long-term CO2 storage to reduce anthropogenic CO2 emissions to the atmosphere. The Madison Group in the North Dakota Williston Basin provides the greatest potential for geologic sequestration in either deep saline aquifers or depleted oil reservoirs. Little is known about the geochemical reactions that take place when supercritical carbon dioxide is injected into deep saline aquifers at geologic conditions similar to those found in potential sequestration units of …
