Was compression ever installed? An announcement was made stating that compression was being sourced. I have seen some comments on this board asking how that worked out.
Gas production from Aminex’s Kiliwani North field in Tanzania has hit a glitch caused by low reservoir pressure and inlet pressure restrictions at a gas processing plant, writes Iain Esau.
Output from the Kiliwani North-1 (KN-1) well at the field is currently below 1 million cubic feet per day and fluctuating.
After studying existing field data, London-listed Aminex believes the problem is because the well is draining only a compartment in the greater Kiliwani North structure and is exhibiting slow recharge across faults or via “tortuous pathways” in the structure.
Partner Solo Oil said it “does not currently believe that there will be a material impact on the 28 billion cubic feet of gross resources independently estimated for KN-1."
The operator is in talks with state-owned Tanzania Petroleum Development Corporation to lower inlet pressure at the process plant and about the installation of compression facilities to boost production rates.
Suitable wellhead compressors are currently being sourced, said Aminex, while Solo said another option being considered is to maximise recovery of this initial well’s resources by drilling step-out prospects in the development licence after reviewing seismic data.
Kilwani North-1 was brought on stream in April last year with output in 2016 averaging 15 MMcfd.
