Origin Energy Limited advises that at 12pm EST on 19 March, the top of the reservoir (Farewell Fromation) in the Kupe South 8 (KS-8) well has been intersected with elevated gas shows, coring operations completed and the 8-1/2 inch section drilled to a planned final depth of 3,834m MDRT (measured depth from rotary table).
Reservoir evaluation logs will now be run and upon completion, it is planned to set and cement the 5 inch liner.
Drilling began at 22:40 hrs on 19 December 2007. Progress of all three development wells in permit PML 38146 is summarised as follows:
22 inch 17 inch 12-1/4 inch 8-1/2 inch
KS-6 560m 2,000m 2,895m 3,385m
KS-7 566m 2,000m 3,116m
KS-8 568m 2,184m 3,429m 3,834m
*Depths are cumulative and show total well depth
Each of the three production wells will be drilled by the ENSCO 107 jack-up drilling rig to a vertical depth of approximately 3,400 metres.
The Kupe Project drilling campaign is being undertaken on a “batch-drilling” basis. This process involves completing the same section of each of the three wells before proceeding to the subsequent section and is a more efficient approach than drilling the wells separately.
