Decades of oil and natural gas production around the world have resulted in a decline of these conventional resources. Basically, most of the oil and natural gas that can be produced using traditional methods is already being accessed. As new technologies are introduced, oil and natural gas producers are able to produce “unconventional” oil and natural gas resources that were previously impossible to obtain. Unlike the conventional pools of oil and natural gas, unconventional oil and natural gas do not flow naturally through the rock, making them much more difficult to produce. Think of the difference between a sponge and a piece of clay: it’s easy to squeeze water out of a saturated sponge that’s conventional oil and natural gas; squeezing water out of saturated clay is harder that represents unconventional oil and natural gas, and the challenge forces producers to find new ways to release the oil and gas. Unconventional often refers to low permeability rock where the pores are poorly connected, making it difficult for oil and natural gas to move through the rock to the well.
Unconventional oil and natural gas, shale gas in particular has been called the future of gas supply. While its development is in the very early stages, it has tremendous economic potential and we know that the interest in these considerable resources will increase
So are unconventional and conventional oil and natural gas the same? Regardless of how they are produced or the rock they come from, unconventional oil and natural gas are essentially the same as their conventional counterparts. The term “unconventional” simply refers to the methods that are used, as well as the types of rock from which the oil and natural gas are produced.
