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 ...
Modeling Multicomponent Gas Flow in Liquids Rich Shales
(2016-05)
Production data acquired from liquids-rich shale reservoirs show a few very interesting trends:
1. A relatively constant gas-oil ratio (GOR) or condensate-gas ratio (CGR) although flowing bottomhole pressures may be below ...
EXPERIMENTAL STUDY OF PROPPANT TRANSPORT IN HORIZONTAL AND DIRECTIONAL WELLS
(2016)
Wellbore cleanouts represent the main application of the coiled tubing (CT) industry. A typical cleanout operation designed to remove solids from the wellbore using stationary circulation method involves tripping the CT ...
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 ...
ECONOMIC FEASIBILITY STUDY OF SEVERAL UTILIZATION ALTERNATIVES FOR A STRANDED OFFSHORE GAS RESERVOIR
(2019-12-13)
Floating Liquefied Natural Gas (FLNG) has been on the rise in recent years to meet growing energy demand, worldwide. As energy consumption and exploitation of onshore unconventional gas reservoirs continue to grow while ...
Experimental Study of Proppant Pack Deformation
(2016)
Unconventional reservoirs, especially shales are drilled horizontally and hydraulically fractured for economical production. Proppant is carried and placed with the use of fracturing fluid to maintain fracture conductivity ...
Modeling Microemulsion Phase Behavior With Consideration of Phase Partitioning of Co-Solvent
(2017-05-12)
Co-solvents are widely used to improve chemical flooding formulations design, but partitioning of co-solvent within phases has great impacts on microemulsion phase behavior. Microemulsion phase behavior plays a key role ...
