Unconventional natural gas, which includes shale gas, tight gas, coal bed methane, and methane hydrates, has been more difficult and costly to exploit than conventional deposits, until recently.
Is unconventional natural gas more difficult to exploit? Unconventional natural gas, which includes shale gas, tight gas, coal bed methane, and methane hydrates, has been more difficult and costly to exploit than conventional deposits, until recently.
What are the different types of unconventional natural gas? Essentially, however, there are six main categories of unconventional natural gas. These are: deep gas, tight gas, gas-containing shales, coalbed methane, geopressurized zones, and Arctic and sub-sea hydrates.
What is the most abundant unconventional natural gas? Methane hydrates are the most abundant unconventional natural gas source and also the most difficult to extract. While there is much uncertainty about the total size of the methane hydrate resource, it is conservatively estimated to be 4,000 times the amount of natural gas consumed in the United States in 2010.
What is the process of unconventional natural gas production? Learn more: Process of unconventional natural gas production (hydraulic fracturing and shale gas extraction) Natural gas and shale gas extraction operations can result in a number of potential impacts to the environment, including:

What are the types of unconventional natural gas resources? There are three major types of unconventional natural gas resources: This is natural gas extracted from shale gas formations. The shale is acting as the source, reservoir and the trap for the natural gas. These kinds of natural gas formations have very low porosity and permeability in the Nano-Darcy range.
What is unconventional gas? Unconventional gas refers to natural gas that requires advanced production methods. Main types include gas within tight pore spaces – shale gas and coal bed methane – and gas that is trapped in ice on the sea floor – gas hydrates.

Why is it so difficult to extract unconventional natural gas? Because it is more difficult to extract, unconventional natural gas can only be extracted if special technology is developed, and if people are willing to pay enough for gas to justify the extra extraction costs. Typically unconventional resources cost more to extract than conventional methods.
Which unconventional natural gas resources have the greatest range of uncertainty? Of all the unconventional gas sources, the geopressured aquifers have the greatest range of uncertainty. The contribution of this resource, although a high-energy-cost source, could range from an important 50 Tcf to over 1000 Tcf of future natural gas and other associated energy.
Is unconventional natural gas more difficult to exploit?
What is unconventional natural gas? In the broadest sense, unconventional natural gas is gas that is more difficult or less economical to extract, usually because the technology to reach it has not been developed fully, or is too expensive. For example, prior to 1978, natural gas that had been discovered buried deep underground in the Anadarko basin was virtually untouched.
Is deep gas more expensive than conventional natural gas? However, deep gas is still more expensive to produce than conventional natural gas, and therefore economic conditions have to be such that it is profitable for the industry to extract from these sources. Another form of unconventional natural gas is referred to as tight gas.
Is drilling for deep natural gas economically practical? Drilling for deep natural gas is not always economically practical, although techniques to extract it have been developed and improved. Shale gas is another type of unconventional deposit. Shale is a fine-grained, sedimentary rock that does not disintegrate in water.
What is the most abundant unconventional natural gas? Methane hydrates are the most abundant unconventional natural gas source and also the most difficult to extract. While there is much uncertainty about the total size of the methane hydrate resource, it is conservatively estimated to be 4,000 times the amount of natural gas consumed in the United States in 2010.
