Importance of Capillary Heterogeneity in Developing a Representative Reservoir Model for Shales with Complex Fractures
(2016-12-16)
Our advancement in hydraulic fracturing has enabled us to produce shale formations economically. The formation stimulation is successful when the effective transport properties of the formation is improved significantly, ...
EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF ROTATIONAL SPEED AND WEIGHT ON BIT ON DRILLSTRING VIBRATIONS, TORQUE AND RATE OF PENETRATION
(2017-05-12)
Experimental investigation was carried out on an automated drilling rig fabricated for the Drillbotics competition. The effects of rotational speed and weight on bit were observed on drillstring vibrations, torque and rate ...
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 ...
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 ...
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 ...
INTERPRETATION OF INTER-WELL CHEMICAL TRACER TEST
(2017)
For the first time, this thesis presents a new approach to characterize reservoir layering and cross flow between layers using Inter-Well Chemical Tracer Test (ICTT). ICTT is a well-known reliable test for reservoir ...
Impact of Viscous Acid-in-Oil Emulsion Formation on Well Productivity Following Acid Stimulation
(2016-12-16)
Acid stimulation techniques matrix acidizing and acid fracturing are commonly applied in carbonate reservoirs. The goal of such techniques is to increase well productivity by enhancing permeability in the near wellbore ...
Transport Phenomena in Micro Scale Channels and Pores by Numerical Simulations
(2014-12-12)
In this thesis, the lattice Boltzmann method (LBM) in conjunction with the Lagrangian particle tracking (LPT) algorithm are employed to numerically investigate: (i) the hydraulic responses to a linear array of finite-length ...
