TAG Oil Ltd. announced successful initial flow testing at the Cardiff field and further information on its Supplejack-1 well flow testing program.

Cardiff (100%)

Cardiff-3 well has successfully conducted an interim flow test with gas and condensate produced to surface.

Based on the preliminary test results, further long term testing will need to be undertaken in order to support commercialization of Cardiff production via tie back to the TAG's nearby Cheal A facility.

The Cardiff field is located on TAG's 100% owned Cheal oil permit in the Taranaki Basin, North Island of New Zealand. The Cardiff field lies beneath TAG's producing Cheal field in the deeper Kapuni formation, named after the nearby Kapuni field, which was New Zealand's first major gas discovery and has produced 1.4 Tcf of gas and 65 mmb of condensate to date.

Three Cardiff wells have previously tested gas to surface, but not in commercial volumes due to mechanical damage to the reservoir during completion. However, following a review of existing opportunities in TAG's portfolio, the Cardiff-3 well was identified as having the potential to become a producer following clean-up operations.

Cardiff resources have been previously estimated to contain 160 Bcf of P50 best estimate gas initially in place and 5.5 mmb of condensate initially in place in a report prepared by Sproule International in accordance with NI 51-101 requirements. TAG plans to update the resource estimate based on the results of the recent testing, as necessary.

Supplejack (100%)

Subsequent testing operations and analysis have now been completed on the Supplejack-1 well which, as reported on November 8, 2016, had tested at rates of up to 7.2 mmscf/d from the Mt. Messenger Formation before being limited by mechanical constraints.

Initial estimates by TAG indicate that the Supplejack-1 well is an economic discovery, which contains approximately 2.8 Bcf original gas in place as a mid-case estimate, with recovery factors approaching 90% with compression. Initial production rates are forecasted at over 2 mmscf/d.
