Initial production commenced from the Kiliwani North-1 well (KN-1) on 4 April. KN-1 is tied into the regional pipeline infrastructure and will deliver gas to the new adjacent Songo Songo processing plant, ultimately serving the local power market.
Aminex expects production to build up to an anticipated production rate of 25-30 MMcfd (approximately 4-5000 boe/d over the next 90-100 days. Initial production rates will be carefully managed to allow for testing and commissioning of the gas processing plant and pipeline, while recording critical pressure and flow rate measurements to determine the optimal flow rate to maximize the life of the reservoir.
The field has been independently ascribed to produce dry clean gas under high natural pressure (1600 psi) from the high quality Neocomian late Cretaceous reservoir. The Kiliwani North -1 well tested at 40 MMcf/d.
Together with Tanzania Petroleum Development Corp. (TPDC), the company plans to conduct a well test during the production build up to determine the optimal flow rate. It is this optimal flow rate that will become the commercial production rate and Aminex intends to flow gas at this rate for as long as possible prior to a natural decline in production. KN-1 represents contingent resources (2C) of gross 28 Bcf gross.
With first production complete, Aminex expects to book reserves for Kiliwani North later this year.
The Kiliwani North Development license is operated by a wholly-owned subsidiary Aminex with a 55.575% working interest (expected to reduce to 51.75% as a result of a partial disposal announced on 4 April 2016) and the field will provide the company with its first significant African production revenues. Partners include Bounty Oil & Gas (9.05%), Rak Gas (23.75%), TPDC (5%) and Solo Oil (10%).
