INVESTIGATION OF PLUGGING IN ORIFICE, SLOT, AND PORE-THROAT BY FINE PARTICLES
(2010)
orifice- or slot-to-particle-size ratio on flowing fluid conditions and plugging time that lead to particle bridging. It was demonstrated that the critical orifice- or slot-to-particle-size ratio vs. particle-volume-fraction ...
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 ...
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 ...
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 ...
Data Assimilation Using The Ensemble Kalman Filter With Emphasis On The Inequality Constraints
(2010)
The reliability of reservoir models generally increases as more data are included during their construction. In the recent past, the ensemble Kalman lter (EnKF) technique has established itself as a viable data assimilation ...
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 ...
MATRIX HETEROGENEITY EFFECTS ON FLUID TRANSPORT IN POROUS MEDIUM: USING PERTURBATION THEORY
(2010)
In this dissertation the processes of transport and reaction in heterogeneous porous medium is upscaled from pore scale to the scale of interest (e.g., core sample or reservoir scale) and new governing equations describing ...
