⁸⁷Sr/⁸⁶Sr AS A POTENTIAL FINGERPRINT FOR DETERMINING THE PROVENANCE OF TOTAL DISSOLVED SOLIDS ASSOCIATED WITH HYDRAULIC FRACTURING ACTIVITIES IN THE BARNETT SHALE, TEXAS
(2016-05-11)
Over the last decade there has been a dramatic increase in unconventional drilling that utilizes hydraulic fracturing to extract oil and gas. The Barnett Shale in north central Texas has been a significant contributor to ...
Sensitivity of the Younger Dryas climate to changes in freshwater, orbital, and greenhouse gas forcing in comprehensive climate models
(2016-05-11)
The Younger Dryas cooling event (~12,900 years before present) was the most recent abrupt climate change in the geologic record where climate for the Northern Hemisphere returned to a near-glacial state. The cause of this ...
The Characterization of Friable Surface Deposits Across North Africa Utilizing Computer Controlled Scanning Electron Microscopy (CCSEM)
(2016-05-10)
Analysis of the mineral constituents of friable surface deposits from the Burkina Faso and Niger regions, North Africa, was undertaken by computer controlled scanning electron microscopy (CCSEM) to try and identify ...
A MODERN RESERVOIR ANALOG FOR A POORLY DRAINED “HIGH ACCOMMODATION” FLUVIAL SYSTEM: SEDIMENTARY PROCESSES, ARCHITECTURE, AND RESERVOIR CONNECTIVITY OF THE GRIJALVA SYSTEM, TABASCO STATE, MEXICO
(2016-09-12)
High-accommodation fluvial systems are subject to much modeling and substantial rock drilling and imagination, but limited modern field observation. The Grijalva River system of Tabasco State, Mexico offers the opportunity ...
Identifying Source of Lead Particles in Floor Dust Using Computer Controlled Scanning Electron Microscope (CCSEM)
(2016-05-10)
Identifying the sources of lead (Pb) in indoor dust by analysis of the contents of the dust provides an opportunity to mitigate the source of contamination. In this study, it is hypothesized that in residential properties ...
Coupled Geochemical and Nano-Petrophysical Study of the Spraberry-Wolfcamp Trend; West Texas, U.S.A.
(2016-12-16)
With the rise in interest of unconventional plays, efforts have moved to understand these formations across 12 orders of magnitude through nm-km scale. Recent work by others has shown the importance of the nanometer range ...
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 ...
EXPERIMENTAL CONSTRAINTS ON THE MICROMECHANICS OF BRITTLE FRAGMENTATION DURING EARTHQUAKE RUPTURE
(2016-12-09)
Various fault damage fabrics, from gouge in the principal slip zone, to fragmented and pulverized rocks in the fault damage zone, have been attributed to brittle deformation at high strain rates during earthquake rupture. ...
Geomechanical Analysis of Rock Brittleness with Comparisons to the Mineralogical Brittleness Index
(2016-05)
A significant area of research within the Oil and Gas industry centers around the understanding of rock brittleness and fracture mechanics related to inducing and extending hydraulic fractures. This study defines rock ...
