STOS Spuds Patea West-1 into South Taranaki Offshore

Shell Todd Oil Services has started the Patea West-1 well in south Taranaki into the offshore PEP 38737 permit for partners Shell (Petroleum Mining) Co. Ltd and Todd Petroleum Mining Co. Ltd.

Operator STOS spudded the Patea West-1 well on 19 July from a coastal site just north of the town of Patea in New Zealand.

STOS is using the Parker Drilling 252 rig to drill Patea-1 and intends deviating it, by perhaps 1500 m or so, into shallow Miocene-aged sandstones within the Patea prospect, which Todd believes straddles three exploration permits PEP 38737, 38760 and 38719.

The Patea prospect appears to be separated into eastern and western parts by a subsurface basement ridge. Drilling is expected to take several weeks.

The Patea West-1 location is interpreted to be on the same structural closure, but updip, of some of Swift Energy New Zealand's Kauri wells, which have already flowed oil from the shallow Manutahi sandstones.

After Patea-1, Todd is scheduled to drill the Patea East-1 well from the same well site into the onshore permit PEP 38760. Todd has said it will not necessarily use the same rig, to test the shallow oil potential of the eastern part of the Patea prospect, with the target zone predicted to be found at a depth of about 1000m-1100m.
