OMV sees delay with Pohokura well intervention campaign

  • Exploration & Production

Austrian oil and gas company OMV has experienced delay with its well intervention campaign at the operated Pohokura gas field located offshore New Zealand.  

OMV started its campaign at the Pohokura gas field last February to re-establish the deliverability of the existing offshore wells through well intervention activities. For safety reasons, production had to be stopped. The campaign was expected to be completed in late April.

However, OMV said last Thursday that full production from offshore wells was targeted for mid-May, rather than the original goal of end-April.

OMV also said that its Pohokura offshore campaign was progressing steadily with work completed on two wells and platform maintenance activities at an advanced stage.

As the campaign has progressed, some additional time has been required to complete the work scope. The campaign is taking advantage of the rig being onsite and completing additional maintenance to ensure the offshore facility will continue to efficiently deliver gas to market into the future.

Between now and mid-May, OMV anticipates about 18 days of offshore production outages – comprising of intermittent outages for approximately six days followed by a continuous shutdown of about 12 days during decoupling of the rig and platform.

As previously reported, OMV has hired COSL Drilling-owned jack-up drilling rig COSLBoss for operations offshore New Zealand. The contract starts in February and ends on April 30, 2019.

The Pohokura field is located about 4.5 kilometers off the Taranaki coast. Gas and fluids from the reservoir are piped to an onshore production facility where the gas is separated from residual water and light oil. The field has been in production since 2006 and currently meets about 40% of New Zealand’s gas demand.
