Aminex, an Africa-focused oil and gas exploration and production company, has seen production from its Kiliwani North drop due to issues at the gas processing plant in Tanzania.
Aminex said on Monday that production from the Kiliwani North-1 well offshore Tanzania was fluctuating below 1 million standard cubic feet per day due to low reservoir pressure and inlet pressure restrictions of the gas processing plant.
The company added that a review of the existing technical data concluded that Kiliwani North-1 was currently draining a compartment within the greater Kiliwani North structure and was exhibiting slow recharge across faults or via tortuous pathways.
Production from Kiliwani North began in April 2016, and the well was used to commission the new TPDC operated Songo Songo Island processing facility. The field is adjacent to the Songo Songo Field which has been on stream since 2004. Kiliwani North-1 was a vertical well drilled from the island.
Aminex operates Kiliwani and the well with a 57.4474 percent interest through its wholly owned subsidiary Ndovu Resources Limited.
As far as prior production is concerned, the average 2016 production from Kiliwani North-1 well stood at 15 million standard cubic feet per day but reached as high as 30 mmcf per day with a sale price of approximately $3.07 per mcf.
Aminex also said on Monday that the company was in advanced discussions with the Tanzania Petroleum Development Corporation (TPDC) to lower inlet pressure at the gas processing plant and for the installation of compression facilities to boost production rates.
The company added that there might be an adjustment to the carrying value of the Kiliwani North asset, which the company does not expect to be material.
Also, following the drilling of the onshore Ntorya-2 appraisal well in the Ntorya gas field, estimated with Pmean gas 1.3 tcf initially in place, Aminex commissioned a new independent report on all its Tanzanian resources which will be completed in early 2018.
