Horizontal well productivity and wellbore pressure behavior incorporating wellbore hydraulics.
(2001)
This research reviews the equations used to determine horizontal well productivity, the models used for wellbore pressure, and develops a new method to estimate horizontal well productivity incorporating the effects of ...
Chemoporoelastic solution of transversely isotropic saturated porous media.
(2004)
The solution is closed-form in the Laplace domain; and is then inverted to the time domain by using Stehfest's (1970) algorithm. This solution simulates the chemoporoelastic process triggered by drilling a borehole in ...
Acoustic anisotropy measurements and calibration of the non-hydrostatic in-situ stresses in a wellbore.
(2007)
The comparison of the static and dynamic stress-strain data (measured from borehole strain gages and velocities) indicates that velocities have to be calibrated according to the rock type to take into account the specific ...
History matching production data using the ensemble Kalman filter.
(2006)
In this dissertation, the ensemble Kalman filter (EnKF) is refined for applications to the problem of history matching. This method assimilates data sequentially whenever data are acquired. It is a Monte Carlo approach, ...
Integration of time-lapse seismic data into automatic history matching.
(2005)
As an alternate to automating history matching through the minimization approach, the ensemble Kalman filter (EnKF) can be used to rapidly update the estimate of model variables. One advantage of the EnKF method is that ...
3-D numerical simulation of horizontal well gravel pack.
(2004)
The modeling equations consist of five partial differential equations with five dependent variables, all of which were solved simultaneously. The system of partial differential equations was approximated using the ...
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 ...
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 ...
Theoretical and experimental studies of power-law fluid flow in coiled tubing.
(2006)
Abstract not available.
NON-NEWTONIAN POWER-LAW FLUID FLOW IN ECCENTRIC ANNULI: CFD SIMULATION AND EXPERIMENTAL STUDY
(2009)
Numerous publications have addressed the problems inherent to calculating wellbore hydraulics in eccentric annulus. The challenge of theoretical and numerical studies of fluid flow in an eccentric annulus is mainly due to ...
