Tag informs Taranaki plans

Tag Oil has several operational activities planned in the Taranaki basin of New Zealand, where net production from its Cheal and Sidewinder fields has recently averaged approximately 1300 boe/d over February 2017.

Clean up and testing operations are continuing on the Cardiff-3 well in permit PMP 38156 which continues to flow intermittently at rates of 200 boe/d.

Tag said it is planning several upcoming interventions to improve and stabilize flow rates out of the well to correct formation damage which occurred during drilling in 2013.

At Cheal, the Cheal-B waterflood is continuing with injection of approximately 900 bbl/d of water. Recent production rates from wells draining the Cheal-B pool have indicated that the wells are beginning to experience a positive production rate impact from the waterflood program.

This effect is expected to increase over the upcoming months as water injection continues.  A planned 10-day shutdown of TAG’s main Cheal processing facility is planned to commence on April 1st. During the shutdown, routine maintenance will be performed on the plant and production operations at Cheal will be suspended.

Furthermore, its second waterflood project in New Zealand has commenced at the Cheal E field with water injection via the Cheal-E7 well. It is expected that water injection rates will increase to 800 bbl/d, with an initial response projected to be seen in calendar Q3 2017.

Drilling operations have been completed at the Supplejack-A2X exploration commitment well having reached the planned TD of 1,740 m. Well logs indicated the presence of well-developed reservoir sands; however, the sands were found to be water wet and the decision has been made to plug and abandon the well.

The well was targeting a potential extension of the Supplejack field, which was successfully tested late last year to flow gas at rates of up to 7.2 MMscf/d from the Mt. Messenger formation.

All current drilling commitments on the Waitoriki permit have now been met and development of the Supplejack field is continuing with first gas estimated for calendar Q4 2017, Tag said.
