Study Notes

Unconventional Fossil Fuels and Extraction Methods

Methane Hydrates contain more organic carbon than coal, oil, and natural gas combined, making it an abundant unconventional fossil fuel resource.
The primary distinction between conventional and unconventional fluids is based on viscosity and liquid gravity.
Natural Gas is not an example of unconventional gas, as it is considered a conventional fossil fuel resource.
'UC' stands for 'Unconventional' in the context of 'UC C C' and 'UC'.
Unconventional Gas is expected to be increasingly unconventional and expensive, reflecting the challenges and costs associated with extraction.
The primary purpose of injecting proppant in hydraulic fracturing is to keep fractures open and allow gas to flow out.
Shale gas accounted for 79% of total US gas production in 2021.
The Ordovician Utica Shale and Jurassic Kimmeridge Clay are identified as source rocks for 'shale gas' reserves.
European shale gas extraction has faced bans in multiple years, indicating opposition to this extraction method.
Production decline curves in the North Dakota Shale Oil province demonstrate a rapid decline from initial production rates.
Tight oil contributed significantly to US oil production in 2021.
Induced seismicity from hydraulic fracturing has been noted in various locations, including Arkansas, England, and the UK.
