What is the difference between shale gas and conventional gas?
Shale gas has the same composition as natural gas. Every shale gas is a natural gas, the difference between the types of gases are the locations of the reservoirs. Natural gas can be found in big amounts, while shale gas is trapped inside the microcracks of a rock.
What are shale gas plays?
Shale Gas Play – A set of discovered, undiscovered or possible natural gas accumulations that exhibit similar geological characteristics. Shale plays are located within basins, which are large-scale geologic depressions, often hundreds of miles across, which also may contain other oil and natural gas resources.
What are the arguments against using shale gas?
Apart from water, other potential environmental problems entailed by industrial exploitation of shale gas include: impact on biodiversity and natural conservation; noise pollution; worsened local air quality; the risk of enhancing seismic movements due to hydraulic fracturing or injection of large volumes of wastewater …
Is shale gas better?
Shale gas is having a beneficial impact on supplies and consumer prices for natural gas, as well as additional environmental benefits: Natural gas provides a quarter of overall U.S. energy; It is used to generate a quarter of the nation’s electricity.
Can shale gas replace natural gas?
In contrast, the low-carbon substitution effect means that – in addition to replacing conventional natural gas – shale gas crowds out technologies such as renewable energy sources and nuclear power, leading to higher greenhouse gas emissions.
Is shale gas clean energy?
Composed of methane, shale gas is a clean and efficient energy resource (Li et al., 2016). The production of shale gas drives the world’s natural gas production growth (EIA, 2016). Consequently, shale gas provides new opportunities for strengthening energy security while reducing carbon emissions (Wang and Li, 2017).
What are the advantages of shale gas?
It notes that done properly, shale gas development can enhance energy security and the availability of energy fuels, lower natural gas prices, offer a cleaner environmental footprint than some other fossil fuels, and enable local economic development.
What is a basin in oil and gas?
Geological basins are the birthplace of oil and gas reserves. These large, low-lying areas are formed by the movement of plate tectonics (the earth’s crust) with a variety of environmental settings. Basins are landscapes of the past, which have been filled in with rocks and sediments accumulated over millions of years.
Is fracking more beneficial or harmful?
On the benefits side, fracking increases economic activity, employment, income and housing prices. But, it also brings more truck traffic, increases in crime and potential health impacts possibly due to air and/or water pollution.
What are two disadvantages of fracking?
Air pollution and water contamination due to the toxic chemicals used in hydraulic fracturing are the greatest concerns within fracking sites, while the need for wastewater disposal and shrinking water supplies are also pressing issues directly related to the procedure.
Who uses shale gas?
Typically, shale gas consists of 70 to 90 per cent methane (CH4), the main hydrocarbon target for exploration companies. This is the gas used for generating electricity and for domestic heating and cooking.
Is shale gas good for climate change?
Global context As it gradually redraws the global energy map, shale gas may reduce greenhouse gas emissions on a country by country basis.
What is the difference between basins and tight sand and shale plays?
We are going to explain the differences in basins, tight sand, and shale plays in a three-post series. Basins are geographically the largest of the three, so we will start there. A basin is a dip or a depression in the earth’s surface, a bowl if you will. They generally have sides higher than the bottom.
What are the shale gas and shale oil play regions?
This document provides a brief description of shale gas and shale oil plays in the United States organized by chapters based on the oil and gas supply module regions. The regions included in this document are the Northeast, Gulf Coast, Mid-Continent, Southwest, Rocky Mountain, and West Coast Region.
How much shale gas is in the Ardmore basin?
USGS Comparison In 2010, USGS conducted an assessment of the Woodford shale in the Arkoma Basin. They estimated that the total undiscovered resource is between 6,065 and 14,036 Bcf, with a mean of 10,068 Bcf. The shale gas resource in the Ardmore Basin has not been evaluated by USGS.
How much gas is in the shale gas play?
The shale gas play has an average EUR of 1.7 Bcf per well and approximately 31.96 Tcf of technically recoverable gas. The shale ranges from 1,000 to 7,000 feet deep and 20 to 200 feet thick. These values are summarized in Tables 27 and 28.
