The Northern Fields is made up of eight oil and/or gas fields that are at different stages of development. The two giants, Raudhatain and Sabriyah, were the first to be brought onstream and have been producing for more than fifty years. Abdali and Ratqa on the Iraqi border are less developed, while Bahrah has been the focus of little development activity since its discovery in 1956. The Northern Fields is a key area for the country's capacity expansion plans. The operator Kuwait Oil Company (KOC) plans to raise both oil and gas capacity primarily through the Lower Fars heavy oil and Jurassic non-associated gas developments.
