Chief executive Dave Bennett told EnergyReview.Net from Wellington that a multi-rate test of the well, consisting of 8-hour flows on four different choke sizes, finished last Sunday and that the well was now shut in for a pressure build-up.
The company would not be releasing data relevant to long-term productivity or possible recoverable reserves until after the well had been re-opened next Sunday.
Last week's initial flow testing of the topmost 15m, from 2824-2839m, within the Tariki sandstones had produced flows of about 5 million cubic foot of gas per day through a 1/2" choke.
Associated condensate to gas ratios of up to 40 barrels per million standard cubic foot of gas had been recorded, with the first 200 barrels of premium clear light oil (with a 52 degree API gravity) trucked to storage near Port Taranaki late last week.
Bennett would today not be drawn on possible recoverable reserves, though he did say the entire 36.5m upper Tariki sandstones interval looked to be hydrocarbon-bearing. So reserve estimates would probably be based on that 36.5m interval.
No formation water had yet been produced during testing of the top zone and upside potential existed for further drilling into the structure updip from the present location.
Fellow PEP 38736 partner, Aussie company Tap Oil, estimates potential recoverable volumes at Kahili could be of around 14 mmbbls of oil and 18 bcf of gas.
Bennett added that the Tabla-1 exploration well, being drilled by New Zealand Oil and Gas within the nearby Ngatoro mining licence PMP 38148, was now over 900m down, on the way to the 1828m target depth.
