NANO-PETROPHYSICS OF THE HYBRID SHALE-OIL BONE SPRING FORMATION, LEA COUNTY, NEW MEXICO
(2017-05-23)Despite the increased hydrocarbon production in hydraulically stimulated unconventional reservoirs, how fluid flows through the rock matrix in these reservoirs is still not well understood. It has been shown that much of ... -
Nano-petrophysics of the Marcellus Formation in Pennsylvania, USA
(2019-05-07)Characterizing unconventional shale reservoirs consisting of nano-size pores and pore networks are complicated due to their complex geometric structure and restrictive fluid transport abilities. Technological advancements ... -
Nano-petrophysics study of Haynesville Shale, East Texas, USA
(2019-05-14)As one of the most productive shale gas plays, the Haynesville Shale has a high geopressure gradient and high temperature, but with a lack of petrophysical understanding. To analyze the pore geometry and wettability ... -
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 ... -
Nano-scale Petrophysical Studies of The Gothic Shale Interval in the Paradox Basin, Colorado, U.S.A.
(2017-12-01)Hydrocarbon production from shale has become a main energy source for the United States. Consequently, an increased knowledge of the petrophysical properties of shale such as porosity, permeability, tortuosity, and ... -
NANOPETROPHYSICAL CHARACTERIZATION OF THE UPPER MANCOS SHALE IN THE SAN JUAN BASIN, NEW MEXICO, U.S.A.
(2022-09-01)The San Juan Basin is no stranger to oil and gas production and the Mancos Shale is one of the formations of the basin that had been producing petroleum since the early 1920’s as conventional, and recently as, unconventional ... -
Nanopetrophysical Characterization of the Wolfcamp A Shale Formation in the Permian Basin of Southeastern New Mexico, U.S.A.
(2019-12-05)The Permian Basin has been producing oil and gas for over a century, but the production has increased rapidly in recent years due to new completion methods such as hydraulic fracturing and horizontal drilling. The Wolfcamp ... -
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 ... -
Nanopetrophysics Characterization of the Mancos Shale Formation in the San Juan Basin of northwestern New Mexico, U.S.A.
(2017-12-01)The Mancos Shale of the San Juan Basin is no stranger to the drilling of oil and gas, but traditional exploration within the region has predominantly been limited to the use of conventional vertical wells. Due to the recent ... -
Nanopetrophysics of the Niobrara Formation in Berthoud State #3 Well
(2016-12-08)The advent of new drilling and completion technologies over the past two decades has made unconventional shale reservoirs the focus of much of the oil and gas exploration and production throughout the United States. Despite ... -
NO MAJOR CHANGES ON PALEOCLIMATE AND PALEOENVIRONMENT ACROSS THE EOCENE–OLIGOCENE TRANSITION IN THE CENTRAL ROCKY MOUNTAINS
(2015-12-08)Earth’s climate has experienced dramatic cooling during the Eocene-Oligocene Transition (EOT) based on well-constrained marine geological records, however, a consensus on the terrestrial responses to this event has not ... -
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 ... -
Numerical Simulation Of The Base-level Buffers And Buttresses Conceptual Model Of Fluvial Systems
(Geology, 2012-07-25)A Buffer in fluvial stratigraphy is a potentiometric surface which defines either: a) the lowest possible depth to which streams will incise; or b) the maximum elevation to which aggradation will occur; together, these ... -
Observations on the magnetic iron oxide content of particulate matter in the Sahel
(2019-05-06)Atmospheric dust influences many processes throughout the biosphere, hydrosphere, and atmosphere, most notably the climate, marine productivity, and human health. Recognizing the physicochemical characteristics of dust ... -
On The Sensitivity Of Ocean Circulation To Arctic Freshwater Pulses During The Paleocene/Eocene Thermal Maximum
(Environmental & Earth Science, 2010-03-03)The Paleocene/Eocene Thermal Maximum (PETM) corresponds to a period characterized by extreme global warming caused by a massive carbon input into the ocean and atmosphere. Approximately 55 Ma in the early Cenozoic, evidence ... -
On-road Measurement Of NOx And CO₂ Emissions From Biodiesel Produced From Different Feedstocks
(Environmental & Earth Science, 2012-07-25)Biodiesel has generated increased interest in the US and elsewhere recently as an alternative to petroleum-derived diesel. Because it can be produced from domestic feedstocks such as soybeans, canola oil, and even recycled ... -
