Production Testing to Begin at Pohokura-3

Pohokura operator Shell Todd Oil Services Ltd has begun wireline logging of its Pohokura-3 appraisal well offshore north Taranaki prior to production testing. The Ocean Bounty semisub completed coring the reservoir to 3662 meters in the targeted Mangahewa Formation within the Kapuni Group, with at least four cores having been cut. The Ocean Bounty drilled with a 8-1/2 inch bit to a final depth of 3815 meters along hole depth, slightly below the original target depth of 3760 meters.

The Pohokura-3 well, which spudded in late October, 12 kilometers off the Motunui coast, will help define the northern extent of the Pohokura gas-condensate field in PEP 38459.

Meanwhile at the southern end of the field, the Pohokura South-1B well, which is being drilled from onshore, has recently made a faster advance. In the last three weeks the well has drilled from 2000 meters along hole to over 4500 meters towards the along hole target depth of 5500 meters in the Mangahewa sands. STOS is using the Parker Drilling 188 rig to drill a 12-1/4 inch hole from the 2000 meter mark down to approximately 4524 meters, where it is planned to log the hole before running and cementing 9-5/8 inch casing. The deviated well started on September 20, 2002.
