What is tight gas?
Gas is a natural gas that is difficult to access due to the nature of the rock and sand surrounding the deposit. Because this gas is much more difficult to extract than natural gas from other sources, companies require a large financial incentive to it; With rising energy prices, also interest in its extraction. Several global oil and gas companies control significant tight gas reserves and some have released considerable sources to learn more about its more efficient extraction.
Normally natural gas is relatively easy. When the deposit is identified, the well can be sunk and the gas naturally flows into the well, which facilitates its pumping to the surface and distributes it. This is because natural gas is usually surrounded by deposits of porous rocks, with lots of small holes to penetrate the gas. Sometimes the gas is almost literally pumped. It is not so permeable, it looks much denser in the cross -section. The lack of permeability locks the gas underground, which makes drilling a profitable well. This gas is also found captured in uHelne deposits. To get to IT, it is necessary to find a "sweet place" where a large amount of gas is accessible, and sometimes use different means to create a pressure vacuum in a well that pulls the gas out of the surrounding rock.
historically, such deposits were written as "irreversible", but as the demand for natural gas grew, many companies have reviewed this evaluation and pushed to see if the deposits could get. While tight gas is expensive for extraction, higher gas prices can cause costs to be worth it, especially if the gas has a composition that is favorable to distillation, allowing companies to extract several valuable fractions from one well.
Most GHT gas dates back to the paleozoic era, which means they are at least 251 million years old. The advanced age of these deposits is probably responsible for their inaccessibility; In other words, the gas is tight because the rock koThe hem had more time for thick. These deposits can also be deeper than conventional gas deposits and represent other challenges. Companies that work with tight gas use a number of survey tactics to identify potential gas sources and to target the best drilling places.
