Depositional Environments, Diagenesis, And Reservoir Delineation Of The FCU 1947 Upper Clear Fork Cored Interval - An SEM Image Analysis Approach To Pore System Characterization
(Environmental & Earth Science, 2014-03-12)
Delineating reservoir facies in heterogeneous tidal flat carbonates is a challenge which requires analysis at greater resolutions than wireline logs can provide. Such depositional environments are documented in the upper ...
Leading The James: The Morphological Changes Of The Missouri River And The Subservient James River
(Geology, 2011-07-14)
The James River flows into the Missouri River east of Yankton, SD. The degree to which the morphological changes of the Missouri River had an impact on the course of the James River is debatable. After mapping the Mission ...
The Formation And Obduction Of Ophiolites Since The Late Precambrian
(Geology, 2007-08-23)
Ophiolite formation and emplacement has been episodic since the Late Precambrian. This research study examines ophiolites that formed during the Cenozoic, Mesozoic, Paleozoic and Late Precambrian. The ophiolites were ...
Selenium Speciation Along A Groundwater Flow Path In The Carrizo Aquifer, Southeastern Texas, USA
(Geology, 2007-08-23)
Selenium concentration and speciation [Se (VI), Se (IV) and Se (-II)] was determined along a flow path in the Carrizo Sand aquifer (southeastern Texas). Groundwater sampling was carried out in March 2006, from ten wells ...
