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 ...
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 ...
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 ...
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 ...
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 ...
SELF-DIVERTING NANOPARTICLE BASED IN-SITU GELLED ACIDS FOR STIMULATION OF CARBONATE FORMATIONS
(2017-12)
In carbonate matrix acidizing treatment, a major challenge for the operations is to divert the injected acid from the main flow regime into a relatively lower permeability zone due to the intrinsic and unique geological ...
DRAINAGE BEHAVIOR OF AQUEOUS, POLYMERIC, AND OIL-BASED NITROGEN FOAMS: THEORETICAL AND EXPERIMENTAL INVESTIGATION
(2019-08-01)
Foams can be formulated to have a wide range of densities and viscosities. This unique behavior makes foam suitable for underbalanced drilling where pressure exerted on formation is maintained below pore pressure and at ...
Downhole Geothermal Power Generation in Oil Wells
(2019-12-13)
Sustainable production of sufficient energy to power the world’s economies with minimum environmental footprint have been one of the most significant challenges for decades. As an essential type of alternative energy, ...
THE EFFECT OF PORE SPACE ON FLUID FLOW AND PHASE BEHAVIOR IN TIGHT FORMATIONS
(2019-05)
Unconventional resources have led to a new abundance of natural oil and gas supply all over the world over the past decade and are expected to play a vital role in the future of this industry. Despite tremendous growth of ...
