Nuclear magnetic resonance (NMR) study of freezing and thawing of saturated porous media and application to shale and pore volume compressibility estimation.
(2007)
Conventional logging tool response is complicated by the presence of shale making it difficult to interpret the log response. Water saturation in shales assumes the shales are filled with brines found in nearby sands. In ...
Application of PEBI grid simulation to analyze pressure-transient behavior of hydraulically fractured vertical wells.
(2002)
Because of their flexibility while handling non-orthogonal systems, in this study, PEBI grids, implemented in a commercial simulator were employed to solve the mathematical models. However, it was first necessary to study ...
Physico-chemical behaviors of shale/fluid/solute interaction in geo-environmental and geo-engineering applications.
(2007)
This dissertation examines the rich and complex physical-mechanical behaviors exhibited by shales when exposed to differing solutions over time, temperature, chemical, and stress conditions. Using several unique experimental ...
Effects of resident water and non-equilibrium adsorption on the primary and enhanced coalbed methane gas recovery.
(2006)
This study presents an experimental and theoretical procedure to investigate the effects of the resident water and time-dependency of the sorption process on coalbed and shale gas primary and enhanced recovery by simultaneous ...
Anisotropic poromechanics of the wellbore coupled with thermal and chemical gradients.
(2002)
A generalized anisotropic porothermoelastic formulation incorporating fully coupled thermo-hydro-mechanical response of saturated porous media is developed. Governing equations are tailored for transversely isotropic media ...
Bottom hole analyses of gas kick (inflow) and gas reservoir characterization while drilling underbalanced.
(2005)
This study presents two new models developed to analyze gas flow between the reservoir and the wellbore while drilling underbalanced. Three drilling operational stages were considered in the analyses. These stages are the ...
The poromechanics of naturally fractured rock formations: A finite element approach.
(2003)
The mathematical models have been cast into finite element form and verified against analytical solutions for one-dimensional consolidation and an inclined wellbore in a fully saturated single-porosity formation subjected ...
Non-oxidative conversion of methane in a DC plasma reactor.
(2004)
The interest in natural gas utilization has increased tremendously over the last decade. Natural gas is being looked at as an energy source, as well as a basis for the production of many chemicals. New technologies are ...
