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 ...
DYNAMIC DRILLING FLUIDS LOSS AND FILTRATION: IMPACT OF DYNAMIC WELLBORE CONDITIONS AND WELLBORE STRENGTHENING IMPLICATIONS
(2018-12-14)
Lost circulation (drilling fluid loss) and mud filtration have been investigated over the years because they lead to non-drilling time (NDT) and increase the overall well cost. It is usually the first source of damage to ...
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 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 ...
Pore-scale Modeling and Multi-scale Characterization of Liquid Transport in Shales
(2018-12-14)
Distinct from conventional reservoirs, shale formations have limited pore connectivity and unique pore spatial-distribution. Consequently, theoretical pore-network models developed for conventional formations are not ...
STUDY AND DEVELOPMENT OF IN-SITU CO2 ENHANCED OIL RECOVERY
(2018-05-11)
While the injection of CO2 has great potential for increasing oil production, this potential is limited by site conditions and operational constraints such as the lack of proper infrastructure, limited cheap CO2 sources, ...
INVESTIGATION OF OILWELL CEMENT MIXING: EXPERIMENTAL STUDIES AND IMPLICATIONS FOR MIXING ENERGY THEORY
(2018-05-11)
Cement is a key element of wellbore integrity. Mixing condition for cement and how its properties are affected is of great importance but often ignored in the oilwell cement design. Typical cement slurry properties such ...
CARBONACEOUS NANOSIZED SURFACTANT CARRIERS AND OIL-INDUCED VISCOELASTIC FLUID FOR POTENTIAL EOR APPLICATIONS
(2018-05-11)
This dissertation aims to advance the conventional tertiary oil recovery method, surfactant flooding process. Via injecting a finite slug of surfactant-only or mixture of surfactant/polymer solution into reservoir, surfactants ...
Three Dimensional Thermo-poroelastic Modeling of Fluid Injection and Induced Microseismicity in Naturally Fractured Reservoirs
(2018)
Interests in naturally fractured reservoirs have grown rapidly in recent years due to the increasing energy needs. Understanding the behavior of naturally fractured reservoirs would be beneficial for a variety of engineering ...
THE STUDIES OF CONFINED FLUID PHASE BEHAVIOR IN SHALE RESOURCES
(2018-05-11)
Fluid phase behavior in porous media is governed by not only fluid-fluid interactions but also fluid-wall interactions. In shale formations, a large amount of hydrocarbon fluid is stored within the organic matters where ...
