How is natural gas extracted? Natural gas extraction on land is always done in the same way. First, the gas is traced. Then we drill a well. This takes a maximum of 3 months. The drilling installation then disappears and the gas can be extracted. Depending on the gas field, this can be decades. When a gas field is empty, we clean up everything again. Extraction and purification of natural gas Natural gas flows through the natural pressure in a gas field to the surface through a well. Once above the ground, we clean the natural gas. We filter natural gas condensate, water and other components from the gas. Natural gas condensate, as a type of gasoline, is a valuable by-product. Sometimes the natural pressure in a gas field becomes too low to be able to extract it. We then increase the pressure with compressors. Extracting natural gas at sea NAM is not only active on land. We use modern techniques to extract natural gas from the deep underground under the North Sea. We do this from 24 production platforms at sea. The method of gas extraction at sea is in principle the same as gas extraction on land. Many of the techniques and innovations at sea are first used on land sites. The platforms at sea can of course only be reached by boat or helicopter. MEER OVER HET WINNEN VAN AARDGAS Hoe ontstaat aardgas? Onder hoge druk veranderden plantenresten in veen en later in steenkool. De steenkoollaag werd steeds warmer; zo ontstond aardgas. Historie van aardgas en aardolie Het eerste olieveld in Nederland wordt in 1943 gevonden. In 1959 wordt het Groningen-gasveld aangeboord. Aardgaswinning op zee Circa 28 % van het Nederlandse aardgas wordt op zee gewonnen, uit ongeveer 150 velden. NAM is de derde gasproducent op zee. WELLICHT OOK INTERESSANT Techniek en innovatie NAM ontwikkelt nieuwe technieken: energiezuiniger en milieuvriendelijker. Daardoor kunnen we steeds meer gas uit bestaande velden en gas uit kleinere velden winnen. Aardbevingen Een aardbeving is een trilling of schokkende beweging van de aardkorst. In ons land zijn er heel soms natuurlijke aardbevingen. Maar ook gaswinning kan bevingen veroorzaken. Environment NAM protects the environment as much as possible. We promise that, we do that and we have it checked by independent parties. Dutch Petroleum Company Gas and oil extraction Extracting natural gas How is natural gas extracted?
