Thermal Effects in Borehole Stability
(2010)
An accurate wellbore stability analysis depends strongly on the state of knowledge of the problem at hand. Almost in all cases, the state of knowledge for wellbore stability analyses is poor. Values of many parameters and ...
DYNAMIC DRILLING FLUIDS LOSS AND FILTRATION: IMPACT OF DYNAMIC WELLBORE CONDITIONS AND WELLBORE STRENGTHENING IMPLICATIONS
(2018-12-14)
Lost circulation (drilling fluid loss) and mud filtration have been investigated over the years because they lead to non-drilling time (NDT) and increase the overall well cost. It is usually the first source of damage to ...
IMPROVING THE EnKF FOR HISTORY MATCHING: MULTISCALE PARAMETERIZATION AND BOOTSTRAP-BASED SCREENING
(2010)
Although the ensemble Kalman filter (EnKF) has been remarkably successful for history matching and quantifying uncertainty in petroleum reservoirs, there have been problems with the use of small ensembles, and occasionally ...
CORROSION BEHAVIOR OF TUBULARS IN SOUR GAS ENVIRONMENT
(2017)
The existence of corrosive gases (CO2 and H2S) in oil wells under High-Pressure High-Temperature (HPHT) condition exacerbates the severity of tubular corrosion and increases the need for different corrosion mitigation ...
Dual-Porosity and Dual-Permeability Poromechanics Solutions for Problems in Laboratory and Field Applications
(2010)
In this work, a study of anisotropic dual-porosity and dual-permeability poromechanics is presented through generalized analytical solutions for selected problems in laboratory and field applications. For example, the ...
History Matching of 3D Reservoir Models with Complex Non-Gaussian Distributions of the Model Parameters
(2010)
Although the first application of the ensemble Kalman filter (EnKF) as a technique for sequential assimilation of noisy measurements was to a numerical weather prediction problem, remarkable research progress has been made ...
Multiple-Porosity and Multiple-Permeability Poroelasticity
(2013)
Since the advent of basic ideas in the theory of fluid seepage in fissured porous media, much effort has been placed in engineering and science departments of various disciplines in trying to foster the concept of dual-porosity ...
PORE CONNECTIVITY IN SHALE FORMATIONS
(2018-12-14)
Shale formations demonstrate distinct characteristics, such as a wide spectrum of pore size from micro-scale to nano-scale, ultra-low permeability, and complex pore network system. Despite extensive research work over years ...
Modeling Nanofluid Utilization to Control Fines Migration
(2017-05-12)
This dissertation presents analytical solutions to address several unresolved issues on modeling of nanofluid utilization to control fines migration in porous media. Despite numerical simulations, analytical solutions ...
MODELING AND ANALYSIS OF MULTIPLE LARGE SCALE HYDRAULIC FRACTURES IN ANISOTROPIC ROCK
(2018-12-14)
Shales and mudstones tend to exhibit strong anisotropy so that assuming mechanical isotropy in wellbore failure analysis and completion design strategies in shale can lead to inaccurate results. This dissertation focuses ...
