The politics of unconventional oil : industrial and technology policy in Brazil, Malaysia, and Mexico
The oil industry has been an important source of industrial and technological development for countries like the United States, United Kingdom, and Norway but is mostly associated with a range of negative outcomes by the resource curse literature. Studies in this tradition assume that this industry …

Time Series Analysis of Surface Deformation Associated With Fluid Injection and Induced Seismicity in Timpson, Texas Using DInSAR Methods
In recent years, a rise in unconventional oil and gas production in North America has been linked to an increase in seismicity rate in these regions (Ellsworth, 2013). As fluid is pumped into deep formations, the state of stress within the subsurface changes, potentially reactivating pre-existing …

Investigating the social, economic and environmental feasibility of extracting onshore oil and gas in the United Kingdom.
… United Kingdom Government has moved on from the unconventional oil and gas (UOG) development discourse since the moratorium in 2019. Shale gas was expected to be produced commercially and to act as a bridge fuel with arguable lower carbon emissions until renewable energy sources can be produced …

The Water-Energy Nexus for Hydraulic Fracturing
… waste generation and disposal. The rapid rise of unconventional natural gas and oil production through the 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 …

Tar sands or scar sands: the oil sands are a huge benefit to the Canadian economy but is this at the expense of the environment that is left behind for future generations?
Crude oil is an essential resource for the world. About 40% of the world’s total supply of energy, and 95% of the energy used in the transportation industry comes from oil and with global consumption of oil increasing to record highs, and conventional sources of oil dwindling, this makes …

Development of Scaling Crieteria for Waterflooding and Immiscible CO2 Flooding in Unconventional Reservoirs
As conventional oil reserves are depleting, the rising energy demand as well as advancements in well drilling and stimulation technologies have attracted increasingly interests in exploiting the unconventional oil resources (e.g., tight oil and heavy oil). Tight oil resources in Canada are mainly …

Aerosol formation from oil and gas development in the Eagle Ford Shale in two different seasons
Unconventional oil and gas development (UOGD) has grown significantly in the United States in the last several decades. This growth has influenced natural gas availability and reshaped the global energy economy. However, the effects on air quality remain uncertain. This work focuses on …

PRODUCTION FORECASTING FOR SHALE OIL: WORKFLOW
With the demand for oil rising, unconventional oil reservoirs have taken a prominent role in the United States as a source of crude oil. Different methodologies to estimate reserves for shale gas and coal bed methane have, thus far, proved to be reliable, but no simple yet accurate workflow has …

An experimental and numerical study on the fracturing processes in Opalinus shale
The extraction of hydrocarbons from unconventional oil and gas reservoirs relies on a detailed understanding of the fracture processes in shale. Also, underground structures designed for nuclear waste repositories are typically constructed in shale due to its characteristic low permeability. To …
