Article
Hydrocarbons in estuarine sediments provide information on sources of sedimentary organic matter (OM), and they are thus useful for tracing natural and anthropogenic OM inputs to the estuary. Here, we assessed the amounts, compositions and sources of natural and anthropogenic hydrocarbons from the sediments of a large, ecologically important estuar...
Article
Despite the upsurge in hydrocarbon exploration in the Lake Albert Rift Basin (LARB) over the past three decades, systematic characterization of hydrocarbon compositions remains lacking, leading to uncertainties in source rock and oil generation determination. We characterized crude oil compositions and oil sand samples in the northern and southern...
Article
Oceanic anoxia is considered as the immediate cause of the Frasnian-Famennian mass extinction, yet the frequency of anoxia and associated environmental modulators remains unknown. Here, we demonstrate that astronomical forcing paced oceanic anoxic episodes by mediating land-ocean interactions during the Upper Kellwasser (UKW) Event, using an ultra-...
Article
Stratigraphic correlation of well logs is based on interactive, interpreter-based pattern recognition. A skilled interpreter identifies similar patterns (such as upward fining and coarsening) in user-defined well sections and links them using either a conscious or subconscious stratigraphic model. This manual stratigraphic correlation of numerous w...

The Devonian is known for the earliest dispersal of extensive wildfires, but the spatiotemporal diversification pattern and process have not been studied in detail. We synthesize a total of 65 global wildfire occurrences based on fossil charcoals and geochemical (biomarker) evidence from 10 paleogeographic areas across 10 time bins (Lochkovian–late...
Article
Detailed analyses of a siliciclastic coastal reservoir highlights the need for an enhanced knowledge of their depositional model. At the scale of the bed sets, however, it is difficult to determine the depositional model, largely due to a limit in vertical resolution of seismic data and conventional wireline logs. Barriers and baffles, following ei...
Article
The reservoir fluid mobility is by definition the ratio of rock permeability to fluid viscosity. This attribute can be applied to reservoir physical property and permeability evaluation. So far, the only means of obtaining the reservoir fluid mobility over a large range of exploration areas is based on the extraction method. However, the location o...

The global dispersal of forests and soils has been proposed as a cause for the Late Devonian mass extinctions of marine organisms, but detailed spatiotemporal records of forests and soils at that time remain lacking. We present data from microscopic and geochemical analyses of the Upper Devonian Chattanooga Shale (Famennian Stage). Plant residues (...

Using chemostratigraphy, lithostratigraphy, and biostratigraphy to study stratigraphic variability in the Chattanooga Shale in Alabama and associate it with depostional process and other events.
Conference Paper
Full-text available
Devonian to Mississippian shales of the Ouachita and Appalachian orogenic belts produce natural gas at isolated locations across the southern midcontinent region and southern Appalachians. The shales are known by different names in different geographic regions; Barnett in northern Texas, Woodford in southern Oklahoma, Fayetteville in Arkansas, and...
