FUNDAMENTAL HYDRAULIC FRACTURING CONCEPTS FOR POORLY CONSOLIDATED FORMATIONS
(2012)
This dissertation examines -by means of the discrete element method- the mechanisms that govern hydraulic fracturing in poorly consolidated formations. The motivation to take on this project was the widely reported ...
ANALYTICAL AND NUMERICAL ANALYSES OF WELLBORE DRILLED IN ELASTOPLASTIC POROUS FORMATIONS
(2012)
The current wellbore stability analyses for analytical solutions are mostly based on the linear elastic or poroelastic theory. The wellbore is regarded as unstable if the determined elastic/poroelastic stresses anywhere ...
MICRO-STRUCTURE OF GAS SHALES AND ITS EFFECTS ON GAS STORAGE AND PRODUCTION PERFORMANCE
(2011)
This dissertation includes discussions on three fundamental topics that are relevant to gas shale reservoir characterization and engineering. First, pore structure of organic-rich gas shale samples are investigated at the ...
EXPERIMENTAL INVESTIGATION, CORRELATION, AND DIMENSIONAL ANALYSIS OF NEAR-WELLBORE FORMATION TREATMENT BY GEL PARTICLES AND PARTICLE-GEL SYSTEM
(2014-12)
Reservoir permeability heterogeneity with high permeability zones can create many problems in petroleum reservoirs such as lost circulation of drilling fluids and high water production in hydrocarbon producing wells. These ...
HLD-NAC Based Solutions for Surfactant Flooding
(2016-04-05)
Established technologies like primary recovery methods using gas pressure and other natural forces in the reservoir, and secondary recovery by water flooding can only approximately recover one-third of the crude oil present ...
Three-Dimensional FEM Modeling of Geothermal Reservoir Stimulation Using Stochastic Fracture Networks and Continuum Damage Mechanics
(2014-08)
Unconventional reservoirs are gaining more and more attention in recently years. Pore pressure and temperature variations in unconventional reservoirs during stimulation are of great importance in reservoir exploration and ...
FUNDAMENTAL HYDRAULIC FRACTURING CONCEPTS FOR POORLY CONSOLIDATED FORMATIONS
(2012)
This dissertation examines -by means of the discrete element method- the mechanisms that govern hydraulic fracturing in poorly consolidated formations. The motivation to take on this project was the widely reported ...
INVESTIGATION OF PLUGGING IN ORIFICE, SLOT, AND PORE-THROAT BY FINE PARTICLES
(2010)
orifice- or slot-to-particle-size ratio on flowing fluid conditions and plugging time that lead to particle bridging. It was demonstrated that the critical orifice- or slot-to-particle-size ratio vs. particle-volume-fraction ...
PORE-NETWORK MODELING AND ANALYSIS OF LABORATORY INDUCED HYDRAULIC FRACTURES
(2018-05)
Well stimulation is undertaken to reduce the restriction to flow in a reservoir. Among all the well stimulation techniques, hydraulic fracturing is one of the most widely employed techniques due to the development of shale ...
Wellbore Cleanout in Inclined and Horizontal Wellbores – The Effects of Fluid Rheology, Inclination, and Solids Density.
(2019-08-30)
Recent technical improvements in the drilling process have allowed drilling of high inclination and horizontal wells with longer laterals. The frequency of such wells has increased over time due to their advantage of ...
