The Maari and Manaia fields, operated by OMV New Zealand Ltd, are located in the Taranaki Basin approximately 80 km offshore the north island of New Zealand.
Production from Maari and Manaia fields averaged 8,300 bopd gross (830 bopd net to Horizon Oil) over financial year 2017, impacted by a six- week shutdown in November 2016 for field maintenance and repairs. These repairs – to the water injection system and to the wellhead platform substructure – are now complete and the Company has filed insurance claims to recover a good part of the costs incurred.
A production improvement program for the coming year is underway. This involves workovers, re-perforations, water injection enhancement and installation of surface pumps to reduce well back pressure.
