Abstract
Prirodni plin u SAD-u proizvodi se dugi niz godina, a prva bušotina izrađena je još 1821. godine. Posljednja dva desetljeća rezerve prirodnog plina iz konvencionalnih ležišta u SAD-u se smanjuju, a potrebe za energijom sve više rastu. To je usmjerilo industriju na razvoj tehnologija kojima bi se prirodni plin mogao pridobivati iz nekonvencionalnih ležišta u ekonomski opravdanim količinama. U nekonvencionalna ležišta prirodnog plina ubrajaju se slabopropusni pješčenjaci, duboki akviferi, metan iz ležišta ugljena (engl. Coal Bed Methane - CBM), plinski hidrati i šejlovi. Proizvodnja u SAD-u odvija se iz slabopropusnih pješčenjaka, ležišta ugljena i šejlova. Šejlovi su sedimentne stijene s malom propusnošću iz kojih nije moguće proizvoditi plin u zadovoljavajućim količinama bez primjene horizontalnog bušenja i hidrauličkog frakturiranja. Hidrauličko frakturiranje je postupak utiskivanja fluida za frakturiranje u ležište radi stvaranja pukotine čime se može povećati proizvodnja. Razvoj proizvodnje prirodnog plina iz šejlova utjecao je na tržište prirodnog plina tako da je smanjio ovisnost SAD-a o uvozu prirodnog plina.
Abstract (english)
Abstract: Natural gas in USA has been produced for many years and first well was drilled in 1821. For the last two decades, reserves of natural gas from conventional reservoirs in USA are decreasing and in the same time, demands for energy are increasing. That has turned the industry into developing technologies for economically justified natural gas production from unconventional reservoirs. Unconventional reservoirs are tight gas sands, deep aquifers, coal bed methane (CBM), gas hydrates and gas shale. USA is producing natural gas from tight gas sands, CBM and gas shale. Shale are sedimentary rocks with low permeability, from which is not possible to produce enough natural gas without horizontal drilling and hydraulic fracturing. Hydraulic fracturing is procedure of injection fracturing fluid into a reservoir to make fracture that will increase production. Development of natural gas production from gas shale has affected global market in a way it has reduced dependence of USA for natural gas import.
