The Collier gas field is a natural gas field located off the shore of the Cabo Delgado Province of Mozambique. Discovered in 2012, it was developed by Anadarko Petroleum, determining it to have initial total proven reserves of around 5 trillion ft3 (143 km3). It began production of natural gas and condensates later that year, with a production rate of 50 million ft3/day (1.9×105 m3).[1] [2]
