EXPERIMENTAL AND MODELING STUDIES ON AXIAL OSCILLATION-SUPPORTED DRILLSTRINGS
(2019-05-10)
Extending the reach of high-angle and extended-reach wells through slide drilling operations are hindered by high downhole friction (static and dynamic), which emanates to inefficiencies, such as poor weight transfer from ...
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 ...
Experimental, analytical, and numerical investigations of gas leakage through annular cement
(2020)
Cementing operations present many difficulties worldwide attributable to shallow flows. Cement sheath integrity and durability play key roles in the oil and gas industry, particularly during the drilling and completion ...
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 ...
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 ...
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 ...
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 ...
Decision-Making for Well Placement Optimization in Oil Field Development
(2015)
Well placement is a method to improve oil recovery by drilling new infill wells in a reservoir. Drilling new wells is a critical yet very challenging task in field development, because the optimal well locations are rarely ...
