The Enigmatic Quaternary Shell Bed Deposits of Lake Tanganyika, Tanzania: Linking Anthropogenic Land-Use with Nearshore Sedimentation
(2017-05)
Extensive deposits of carbonate shell-rich sediments in the nearshore environment (< 30 m water depth) of Lake Tanganyika, Africa, form a unique and important habitat for a diversity of endemic crabs, fish, sponges, and ...
Diffraction imaging using Geometric-mean Reverse-Time Migration and Common Reflection Surface
(2017-12)
Diffracted waves contain a great deal of valuable information about small-scale subsurface structure such as faults, pinch-outs, karsts and fractures, which are tightly related to hydrocarbon accumulation and production. ...
Study of stress field in seismogenic processes in Oklahoma
(2017)
The recently increased seismicity in Oklahoma provides a rich catalog that delineates unmapped fault system. In this project, I identify 88 clusters with 20 or more earthquakes using automatic nearest-neighbor approach. ...
Novel Biomarker Distributions in the Chesterian Limestone of the Anadarko Basin, Oklahoma
(2017-05)
18α(H)-Oleanane is a biomarker that is proposed to be derived from β-amyrin, which is produced by angiosperm plants. As such, the presence of 18α(H)-oleanane is often used as an indicator that the petroleum source is of ...
STRATIGRAPHIC ARCHITECTURE OF THE MISSISSIPPIAN LIMESTONE THROUGH INTEGRATED ELECTROFACIES CLASSIFICATION, HARDTNER FIELD AREA, KANSAS AND OKLAHOMA
(2017-05-13)
The Mississippian Limestone formed through complex structural, stratigraphic, and diagenetic processes involving subsidence, tectonic uplift leading to periodic subaerial exposure, changes in ocean chemistry, variability ...
3-D GEOMETRY AND KINEMATIC EVOLUTION OF THE KUPE INVERSION STRUCTURE, SOUTHERN TARANAKI BASIN, NEW ZEALAND
(2017-12)
The Southern Taranaki Basin underwent extension during the Late Cretaceous to Eocene, followed by a compression during the Oligocene to the Late Miocene, resulting in inversion of some of the pre-existing normal faults. ...
DETAILED LITHOSTRATIGRAPHIC CHARACTERIZATION AND SEQUENCE STRATIGRAPHY OF A COMPLETE WOODFORD SHALE OUTCROP SECTION IN SOUTHERN OKLAHOMA
(2017-08)
This work presents a detailed rock-based and stratigraphic documentation of an unpublished and recently discovered Woodford Shale outcrop in the south flank of the Arbuckle Mountains (southern Oklahoma). The exposed section ...
OUTCROP-SCALE STUDY OF THE PERMIAN BONE SPRING FORMATION, BONE SPRING CANYON, GUADALUPE MOUNTAINS, TEXAS: FRACTURE CHARACTERIZATION
(2017-05-12)
A light detection and ranging- (LiDAR) focused outcrop study was conducted on Upper Leonardian Bone Spring limestone in the Bone Canyon, Delaware Basin of West Texas. LiDAR technology is very useful in modeling fracture ...
Comparison of Surface and Downhole Microseismic Acquisition
(2017-12-16)
The most common microseismic monitoring methods used in the industry today are by the use of surface arrays and downhole arrays. In surface acquisition, sensors are deployed on the surface in large two-dimensional arrays, ...
Using 3D Seismic Attributes to Investigate Mud Losses in a Fluvial-Deltaic Sand: An Example From the Oliver Sandstone
(2017)
Drilling operations in an actively developed basin in Wyoming can experience
large quantities of mud losses in a shallow zone along the intermediate (vertical) section
of the wellbore. These losses can negatively impact ...
