More workovers planned at Maari offshore New Zealand
The Maari field offshore New Zealand now has a total of 10 producers and one water injector in service, according to partner Cue Energy.
No further drilling is currently planned, with the priority being to maximize production by optimizing up-time and deliverability of the wells.
The sole naturally flowing well is MR6A, which is now exhibiting increased water cut and which accounts for a large portion of the field’s declining production rates.
All other nine producers rely on electric submersible pumps for continued production and operator OMV is optimizing use of these and topsides facilities to enhance production.
OMV is also adding additional perforations in producing wells to improve production, as was the case with MR8A, where action lifted output by 1,600 b/d.
A similar job in MR9 has added around 500 b/d incremental production. The MR2 well is currently undergoing a workover, with similar activity scheduled for MN1.
The only planned shutdown over the next year will be in December to repair the water injection line. Once this work is complete water injection will be reinitiated, providing pressure support to some of the producers and thereby increasing production and ultimate recovery.
Otherwise, Cue has withdrawn from its three remaining licensesoffshore New Zealand.
