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 …

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
… combined 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 …

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
… an experimental 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 …

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
… emissions (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 …

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 …

Some rock mechanics problems with application for hydraulic fracturing
Hydraulic fracturing is an essential tool used to enhance connectivity in shale gas reservoirs by maximizing the intersection between the hydraulic fracture (HF) and pre-existing natural fractures (NF) or faults. The technique is most effective when the hydraulic fracture crosses natural fractures …

Hydraulic Fracturing and Flow-back Simulation in Unconventional Tight Reservoirs
At present, combination of the multistage hydraulic fracturing and horizontal wells has become a widely used technology in stimulating unconventional tight reservoirs in Western Canadian Sedimentary Basin (WCSB). It is important to understand hydraulic fracture propagation mechanism, effects of …

Effectiveness of microseismic monitoring for optimizing hydraulic fracturing in California
Hydraulic fracturing has fundamentally changed the oil and gas industry in the past 10 years. Bakersfield, California provides a unique case study because steam injection, a type of hydraulic fracturing, has been used there for more than 60 years. Seven companies, varying in size and strategy, use …

Fracturing Illinois: Fields of Political Contention in Hydraulic Fracturing Regulatory Policy
… activity during 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 …

Fractured Discourse: Social Representations Of Shale Gas Development Via Hydraulic Fracturing
Herein I investigate the nature and emergence of social representations of shale gas development (often called "fracking"). Social representations are common sense understandings of complex, novel phenomena generated in the public sphere via communal discourse. I triangulate between results from …
