Why are big trucks needed for gas wells?
There are two kinds of oil and gas deposits: conventional and unconventional. The Barnett Shale is considered an unconventional deposit by geologists because the methane gas is not located in highly porous rock formations which create easy-to-access pockets of gas (known as “conventional” deposits). In the Barnett Shale, the source rock in the shale has to be fractured to release the gas. Two methods are used: • Larger hydraulic fracturing methods use water and sand under high force to break the rock and release the gas. • Horizontal drilling techniques. This unique combination of new technology and techniques was first used in the late 1990s and made drilling for natural gas in the Barnett Shale a reality on a large scale. Drilling for natural gas is more environmentally friendly than drilling for oil. Extracting natural gas is also cleaner. With the advent of directional and horizontal drilling technology, natural gas wells have a much smaller impact on land than drilling vertical we
