Minority partner New Zealand Oil & Gas said yesterday afternoon that flow tests on the Kupe South-7 sidetrack well were completed by 10.30pm Tuesday and a 92m-deep interval, between 3188-3280m measured depth below rotary table, was tested through a 56/64-inch choke, with surface flowing pressure relative to atmospheric pressure of 3051 pounds per square inch gauge (psig).
Sustained flow rates achieved were 41.8 million cubic feet per day (MMcf/d) of gas and 6393 barrels per day of condensate, NZOG said.
The first well to be tested, Kupe South-8, flowed 33MMcf/d of gas and 3840bpd of condensate last weekend, through a one-inch choke, with surface flowing pressure of 2100psig.
The second, Kupe South-6, flowed 41MMcf/d and 6000bpd of condensate through a 56/64-inch choke, with surface flowing pressure of 3030psig.
This concludes the testing phase of the Kupe development wells, which will remain shut-in.
The rig will now move to spud the nearby Momoho-1 exploration well.
The Kupe partners are operator Origin Energy (50%), Genesis Energy (31%), New Zealand Oil & Gas (15%), and Mitsui E&P NZ (4%).
