Cement fatigue and HPHT well integrity with application to life of well prediction
(2009-05-15)
In order to keep up with the world’s energy demands, oil and gas producing companies have taken the initiative to explore offshore reserves or drill deeper into previously existing wells. The consequence of this, however, ...
Associations between hydrological connectivity and resource partitioning among sympatric gar species (Lepisosteidae) in a Texas river and associated oxbows
(2009-05-15)
The middle Brazos River, located in east central Texas, is a meandering lowland
river that contains many oxbow lakes on its floodplain. Flood dynamics of the Brazos
River are aseasonal, and faunal exchange during lateral ...
Fabrication of Niobium sheet for RF cavities
(2009-05-15)
This thesis investigated the microstructure and mechanical property of RRR( high
purity) and RG (low purity) niobium (Nb) sheet material. RRR Nb is used in the
fabrication RF cavities. Our method involves processing bulk ...
Effective fracture geometry obtained with large water sand ratio
(2009-05-15)
Shale gas formation exhibits some unusual reservoir characteristics: nano-darcy
matrix permeability, presence of natural fractures and gas storage on the matrix
surface that makes it unique in many ways. It’s difficult to ...
Modeling well performance in compartmentalized gas reservoirs
(2009-05-15)
Predicting the performance of wells in compartmentalized reservoirs can be quite
challenging to most conventional reservoir engineering tools. The purpose of this
research is to develop a Compartmentalized Gas Depletion ...
Functional analysis of the Arabidopsis PHT4 family of intracellular phosphate transporters
(2009-05-15)
The transport of phosphate (Pi) between subcellular compartments is central to
metabolic regulation. Although some of the transporters involved in controlling the
intracellular distribution of Pi have been identified in ...
Incorporation of analgesics into rodent embryo transfer protocols: assessing the effects on reproductive outcomes
(2009-05-15)
Surgical embryo transfer in rodents is a common procedure in today’s research
laboratory, although little is known of the effect analgesics may have on not only the
recipient female but also the embryos. Two perioperative ...
Neutronic analysis of pebble-bed cores with transuranics
(2009-05-15)
At the brink of nuclear waste repository crises, viable alternatives for the long
term radiotoxic wastes are seriously being considered worldwide. Minor actinides serve
as one of these targeted wastes. Partitioning and ...
Completion methods in thick, multilayered tight gas sands
(2009-05-15)
Tight gas sands, coal-bed methane, and gas shales are commonly called
unconventional reservoirs. Tight gas sands (TGS) are often described as
formations with an expected average permeability of 0.1mD or less. Gas
production ...
Selection of best drilling, completion and stimulation method for coalbed methane reservoirs
(2009-05-15)
Over the past three decades, coalbed methane (CBM) has moved from a mining
hazard and novel unconventional resource to an important fossil fuel that
accounts for approximately 10% of the U.S. natural gas production and ...
