A term applied to natural gas that is difficult and expensive to find and produce; if found, it often is bypassed in favor of more easily obtainable supply that is less costly to produce. Higher gas prices, however, increase the interest in these more-costly gas sources. Examples of unconventional gas can be found in tight sandstone reservoirs and shale, including the increasingly popular Barnett Shale in Texas.
