Fracturing Illinois: Fields of Political Contention in Hydraulic Fracturing Regulatory Policy
… the construction of the Illinois Hydraulic Fracturing Regulatory Act (HFRA). Hydraulic fracturing is a controversial method of oil and gas extraction which created an unusual amount of public interest and participation in policy construction. This dissertation provides an overview of the …

Fracturing processes and induced seismicity due to the hydraulic fracturing of rocks
Hydraulic fracturing is a method used routinely in oil and gas exploitation and in engineered geothermal systems. While used frequently, there are aspects of hydraulic fracturing, such as the propagation of the newly-created fractures and interaction between natural and newly-created fractures, …

Accounting for Remaining Injected Fracturing Fluid
The technology of multi-stage fracturing of horizontal wells made the development of shale gas reservoirs become greatly successful during the past decades. A large amount of fracturing fluid, usually from 53,000 bbls to 81,400 bbls, is injected into the reservoir to create the fractures. However, …

Hydraulic Fracturing in Earth Dams (Boreholes)
The proposed mechanisms of hydraulic fracturing in earth embankment dam cores and boreholes published by various authors have been outlined and compared in this investigation. An experimental study was conducted which reinforces the fact that hydraulic fracturing in boreholes is a tensile …

Freeze fracturing of elastic porous media
… behind this thesis is the phenomenon of fracturing of rocks and other porous media due to ice growth inside pre-existing faults and large pores. My aim is to explain the basic physical processes taking place inside a freezing elastic porous medium and develop a mathematical model to …

Geomechanical review of hydraulic fracturing technology
Hydraulic fracturing as a method for recovering unconventional shale gas has been around for several decades. Significant research and improvement in field methods have been documented in literature on the subject. The heterogeneous nature of shale has made hydraulic fracturing design to be unique …

The Water-Energy Nexus for Hydraulic Fracturing
… processes of horizontal drilling and hydraulic fracturing have shifted the energy dynamic in the United States. Concurrently, the rising utilization of unconventional gas and oil production has intensified the water use for hydraulic fracturing and generation of flowback and produced water …

Hydraulic fracturing of artificially generated soft sandstones
… from petroleum reservoirs. The main aim of fracturing an oil medium is the stimulation of oil and gas production by inducing highly conductive channels leading to a well, from which hydrocarbons will flow. Many applications of hydraulic fracturing take place in soft sandstones using moderate …

Hydraulic fracturing through 3D printing and lattice modelling
… and numerical study on the hydraulic fracturing propagation is conducted using the 3D printing techniques and the lattice modelling. The first half of the thesis presents the experimental studies. Firstly, the potential of 3D printing on rock mechanics is explored by Polylactic acid …

Reducing the environmental impact of hydraulic fracturing pumps
The current approach to hydraulic fracturing requires large amounts of industrial hard-ware to be transported, installed and operated in temporary locations. Typically 70% of the mass of this equipment is comprised of the fleet of truck-mounted pumps required to provide the high pressures and flows …

The Fluid Mechanics of Hydraulic Fracturing (Oil Recovery)
The hydraulic fracturing of thin two-dimensional cracks embedded in porous rock is analyzed. The primary application of the hydraulic fracture process is the stimulation of oil wells of relatively low permeability. This is accomplished by pumping high pressure fluid down the wellbore in an effort …

Acoustic emissions in hydraulic fracturing of Barre granite
… (AE) generated by laboratory scale hydraulic fracturing of Barre granite specimens with single or double flaw geometry. The scope of this work covers the experimental setup and subsequent analyses of these acoustic emissions, which in essence are elastic waves generated by displacements …

Three Essays on the Economics of Hydraulic Fracturing
Hydraulic fracturing has been increasingly used in the USA to economically extract natural gas and oil from newly discovered shale plays. Despite new, more severe, and long term impacts of hydraulic fracturing compared to conventional drilling, regulatory practices are mostly implemented by states …

Optimization of fracturing fluid to increase shale gas production
… producing was demonstrated. Although the hydro-fracturing technology has been conducted in field frequently, sometimes the decrease of permeability has been observed after the treatment. To figure out this phenomenon, the investigation started from the basic characterization of matrix. Believed …

Physical Optimization of Acid Fracturing with Unified Fracture Design
Acid fracturing is a reservoir stimulation technique where a fracture is created by injection of acid into the reservoir instead of conventional proppant slurry. The acid causes differential etching on the fracture walls, creating asperities. These asperities hold up the fracture wall, thus …
