Laboratory imaging of hydraulic fractures using microseismicity.
(2002)
Developing robust algorithms and software for locating the coordinates of hydraulic fracturing-induced microseismic events, and for simulating the first motion of the induced waveforms were central tasks for this research. ...
Production performance of horizontal wells in gas-condensate reservoirs.
(2002)
Gas condensate reservoirs go under two kinds of changes in their lifetime. The phase change and the physical properties change. Both the changes have been handled in this study using the pseudopressure function integral ...
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 ...
Laboratory Characterization of Reservoir Stimulation and Heat Extraction with Application to EGS
(2019-12)
Enhanced or engineered geothermal systems (EGS) could enable extraction of significant geothermal energy from hot relatively dry rock reservoirs. However, issues related to reservoir creation in different type of rocks and ...
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, ...
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 ...
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 ...
An experimental study of crude oil recovery by high pressure nitrogen injection.
(1980)
The results of this experimental investigation showed the compositional distribution of the vapor phase throughout the core during the nitrogen injection process. The mechanism of the nitrogen displacement process was ...
