STOS Seeks More Gas with Kapuni-16 Well

The Kapuni-16 appraisal well, seeking gas-condensate on the eastern flank of the Kapuni onshore field (PML 38839) in Taranaki, has reached an along-hole depth of 3,986 meters and was to begin a 40-meter core of the hole, operator Shell Todd Oil Services Ltd has reported. The well, which is being drilled by Parker Drilling's Rig 188, was spudded on February 8 and was expected to take about five weeks to drill to the along-hole target depth of 4,140 meters.

STOS said that after coring it planned to drill to final well depth, run electric wireline logs and cement 7 inch and 4.5 inch casing in place.

The wellsite last saw drilling action in the late 1970s. "As our 44 year old Kapuni field matures, we need to look for opportunities to maintain its hydrocarbon deliverability" said STOS land assets manager Ron Jantzen.

The Kapuni-16 well and a subsequent well Ngarewa-1, with a target in the Mount Messenger Formation, follows encouraging results obtained from a 3D seismic survey over the Kapuni permit.
