Pohokura Partners to Explore Okoki Structure West of Pohokura Field



The Pohokura gas condensate field partners have been granted a four-year appraisal extension over the Okoki structure a few kilometers west of where the Pohokura offshore production wells are now being drilled.

The Okoki structure lies in a northerly trend parallel to the Pohokura field and mining permit and inside PEP 38 459, the 69 square kilometer western section of the original permit granted before the Pohokura discovery.

The extension has been granted to PEP 38 459 operator Shell Exploration NZ Ltd, and partners OMV New Zealand Ltd, and Todd Pohokura Ltd.

Under the four-year permit work program the partners are required to analyze relevant appraisal information from Pohokura development wells (in particular POB-B) and incorporate into the subsurface model for the adjacent Okoki structure.

If a technical report confirms the subsurface models are validated a mining permit can be applied for.

Two years ago Todd drilled a well Terrace-1 from an onshore site over 2 kilometers offshore into the southern part of the PEP 38 459 permit. The well targeted Kapuni Group Mangahewa Formation sands.

Terrace-1 was plugged and abandoned by Todd after finding no commercially viable hydrocarbons. Shell and OMV did not participate with Todd in the well.
