Unconventional gas

Multiple questions on unconventional gas, often associated with shale gas, may find answer in the analysis of gas formation in the earth’s crust, of geological conditions in which they are formed and accumulated. Gas is formed from the decomposition of organic substances, captive in the mud from waters bottom and subsequent migration towards areas where they are “blocked” and accumulated, forming the gas fields. The time until the formation of a gas field is of millions of years. This process is continuous, organic substances discomposing and determining the production of natural gas. The advanced degree of exhaustion of gas accumulations, known as gas fields, has determined, especially in the U.S., the beginning of studies to extract gas that hasn’t been accumulated, being found in various stages of the gas formation process (after the decomposition of organic substances) and/or migration. Thus, the notion of unconventional gas occurred.
