Production, Development, Exploration

100% owned

TAG holds 100% ownership in two producing fields and lightly-explored development acreage 

34.5% Growth

TAG increased reserves from 2016-17 through acquisition, development, exploitation and appraisal

25% developed

Just 25% of TAG’s Taranaki discovery acreage have been developed to date

Production From Multiple Formations

TAG has two fields in production and under development, the Cheal and Sidewinder fields, which produce from the Miocene-aged, Mt. Messenger (~2000m) and Urenui (~1600m) formations. Ongoing development and step-out drilling in the surrounding acreage has achieved a track record of drilling success, with most of the prospect-rich discovery acreage yet to be explored. TAG’s  field development at Cheal and Sidewinder will continue to fuel TAG Oil’s production growth for many years to come.

Cheal Formations




Taranaki Basin

TAG is a prominant explorer and acreage holder in New Zealand’s Taranaki Basin where average conventional discovery field size is many magnitudes larger than in North America. The Taranaki region is infrastructure rich and has a thriving domestic natural gas market.

Cheal Oil and Gas Discovery

TAG holds a 100% interest in the Cheal discovery which produces oil and gas from the Mt. Messenger and Urenui formation.  Drilling success has provided encouraging results indicating oil  saturation potential across TAG’s entire acreage.
