Geologic Factors Affecting Hydrocarbon Occurrence In Paleovalleys Of The Mississippian-Pennsylvanian Unconformity In The Illinois Basin, Jeremy Taylor London
Geologic Factors Affecting Hydrocarbon Occurrence In Paleovalleys Of The Mississippian-Pennsylvanian Unconformity In The Illinois Basin, Jeremy Taylor London
Masters Theses & Specialist Projects
Paleovalleys associated with the Mississippian-Pennsylvanian unconformity have been identified as potential targets for hydrocarbon exploration in the Illinois Basin. Though there is little literature addressing the geologic factors controlling hydrocarbon accumulation in sub-Pennsylvanian paleovalleys basin-wide, much work has been done to identify the Mississippian-Pennsylvanian unconformity, characterize the Chesterian and basal Pennsylvanian lithology, map the sub-Pennsylvanian paleogeology and delineate the pre-Pennsylvanian paleovalleys in the Illinois Basin. This study uses Geographic Information Systems (GIS) to determine the geologic factors controlling the distribution of hydrocarbon-bearing sub-Pennsylvanian paleovalley fill in the Illinois Basin. A methodology was developed to identify densely-drilled areas without associated petroleum …
Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan
Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan
Earth, Environmental, and Atmospheric Sciences Faculty Publications
A standard planar Kernel Density Estimation (KDE) aims to produce a smooth density surface of spatial point events over a 2-D geographic space. However, the planar KDE may not be suited for characterizing certain point events, such as traffic accidents, which usually occur inside a 1-D linear space, the roadway network. This paper presents a novel network KDE approach to estimating the density of such spatial point events. One key feature of the new approach is that the network space is represented with basic linear units of equal network length, termed lixel (linear pixel), and related network topology. The use …
