Stable Isotopic And Geochemical Studies Of Late Quaternary Stalagmites, South-Central Appalachian Mountains, Eastern North America
(Environmental & Earth Science, 2014-07-14)
A tripartite investigation was conducted utilizing speleothem geochemistry and modern cave environments: reconstruction of paleoclimate variability in southeastern West Virginia that spans the late Pleistocene to mid-Holocene, ...
Sandstone Injectites Record Pre-, Syn-, And Post-folding Deformation At Sheep Mountain Anticline, Wyoming
Sandstone injectites ranging from 30 m to over 1 km in outcrop length intrude the Cretaceous Mowry Formation in the vicinity of Sheep Mountain Anticline (Bighorn Basin, WY). These injectites were sourced by the Peay Member ...
Nucleation Of Thrust Faults Due To Heterogeneous Bedding Plane Slip: Evidence From An Ohio Coal Mine
Oil shales often form the roof and floor rocks of many coal mines in the Appalachian basin. These mines offer outstanding 3D exposures of fresh rocks, otherwise only accessible via boreholes or heavily weathered surface ...
The Variance Of Methane Adsorption And Its Relation To Thermal Maturity In The Marcellus Shale
(Geology, 2015)
In unconventional shale gas plays, gas-in-place is a major factor in evaluating the shale’s potential and determining well density and lateral placement. The two main contributors to total gas-in-place are free gas and ...
FLUID UPTAKE OF THE GODDARD SHALE IN SOUTHEASTERN OKLAHOMA, USA
(2015-12-07)
The South Central Oklahoma Oil Province is the current play for the Goddard shale and is also the main field for the underlying Woodford Formation. As of September 2015, an estimated 40 wells have been drilled to evaluate ...
Depositional Facies And Reservoir Analysis Of The Tyler Formation In The Central Williston Basin, North Dakota
(Environmental & Earth Science, 2014-07-14)
Traditionally, the Pennsylvanian Tyler Formation has been targeted as a conventional reservoir consisting of barrier island and channel sand deposits in the southwestern Williston basin, North Dakota. The purpose of this ...
Trends In Seasonal Climate Variance In The Subtropical Reservoir Joe Pool Lake, Texas: Implications Dissolved Oxygen And Nutrient Distribution
The primary causes of seasonal variance in temperature, hydrological cycle, and nutrient distribution of lakes, and the processes explaining these changes including climate change and land use changes have been investigated ...
Constraining The Near Tip Stresses Around Propagating Earthquake Ruptures: Frictional Response And Off Fault Tensile Crack Development
The near-tip stress, strain, and displacement fields around propagating ruptures are complicated, transient, and depend heavily on the evolution of the shear traction along the advancing rupture. This shear traction evolution ...
Nano-petrophysics Study Of The Three Forks Formation In The Williston Basin, North Dakota, U.S.A.
The Late Devonian Three Forks Formation has increasingly become one of the productive plays in the Williston Basin, North Dakota. This growth has been attributed not only to new drilling and completion techniques but also ...
Nanopetrophysics Characterization Of The Bakken Formation, Williston Basin, North Dakota, USA
The recent oil boom in the US has been attributed to the result of hydraulic fracturing and horizontal drilling of shale plays. However despite this boom, production and maximum recovery is still limited to be only few ...
