Stratigratigraphic architecture and basin fill evolution of a plate margin basin, eastern offshore Trinidad and Venezuela
(2006-05)
Eastward migration of the Caribbean plate relative to the South American plate is recorded by a 1100-km-long foreland basin which is oldest in the west (Maracaibo basin, 65-55 Ma) and youngest in the east (Columbus basin, ...
3-D seismic evaluation of fault control on quaternary subsidence patterns, rates, and related surface morphology in southeastern Louisiana
(2008-08)
Throughout the past century, the Louisiana coastline has been deteriorating at an alarming rate. Fault induced subsidence has been suggested to be one of the likely drivers of this land loss. I directly addressed the control ...
Depositional element morphology and architecture of the Atoka interval, Fort Worth Basin, TX, U.S.A.
(2008-12)
The Atoka Group (Lower-Middle Pennsylvanian) of the Fort Worth Basin (FWB) forms a significant (~2-3 Tcf), and as yet underexploited, domestic gas resource that is often seen as a secondary target as operators make their ...
Subsurface structure, stratigraphy, and regional tectonic controls of the Guajira margin of northern Colombia
(2008-05)
I combine previous data from Mesozoic outcrops in the Guajira Peninsula of northern Colombia with new regional gravity, bathymetric, and seismic interpretations to demonstrate the existence of a 280-km-long, western extension ...
Seismic and stratigraphic interpretation of the Morichito Subbasin, eastern Venezuelan basin
(2008-08)
The Morichito Subbasin is a southwest-northeast oriented depocenter that is located in the Eastern Venezuelan Foreland Basin (EVFB). The Morichito Subbasin covers an approximate area of 1,000 km² between the Serranía del ...
Sensitivity of AVO reflectivity to fluid properties in porous media
(2004-05)
The Zoeppritz equations used in a typical reflection amplitude versus source-receiver offset (AVO) study to calculate the reflection and transmission coefficients do not directly consider the fluids filling the pore space ...
Seasonal water usage by Juniperus ashei : assessment with stable isotopes of hydrogen and oxygen
(2004-08)
The recent expansion of Juniperus ashei (Ashe juniper) on the Edwards Plateau of Central Texas has prompted studies on the impact the juniper expansion has had on the hydrologic regime of the region. This study addresses ...
A calcium isotope growth series of the domestic chicken (Gallus gallus)
(2004-08)
The traditional roles of stable isotopes in paleontology are as indicators of diet or climate. An emerging field of paleontology and geochemistry is to use isotopes in order to make inferences about extinct and fossil ...
Petrographic characterization of the Barnett Shale, Fort Worth Basin, Texas
(2005-08)
Shale sedimentology is one of the less explored areas of sedimentary geology. Shales account for two-thirds of the sedimentary rock record and preserve large portions of Earth's history in relatively continuous successions. ...
Effective porosity estimation from 3D seismic reflection data : Marco Polo Field, Gulf of Mexico
(2007-05)
Seismic inversion is a geophysical tool that uses geologically constrained physical models to infer elastic interval properties (e.g., P-velocity, S-velocity, and density) from seismic interface data (e.g., reflection ...
