Tamarind NZ Onshore is pleased to announce the return to full time production of the Company’s most prolific oil well. Cheal E-1 had experienced a seized rod string in December 2020, rendering the well unable to pump oil. Long-term wax build-up from the paraffinic oil was the culprit, a problem common to all wells in onshore New Zealand, but the intervention was far from routine. Engineering Manager Ryan Beierle commented; “Without the ability to import specialized work-over rig crews into New Zealand due to Covid border closings, we had to fix the well using a little Kiwi ingenuity. Large cranes were employed to pull the rod string out of the hole, where a service rig certainly would have made things a lot easier.” The well was returned to fulltime production by mid-January 2021, a relief for Country Manager Drew Cadenhead; “When it’s our highest cash-flowing well that goes down, we’re grateful our team put on their thinking caps and found a way to bring the well back.”
To progress Tamarind’s strategy of improving performance from under-exploited fields via operational excellence, now even more critical given the continued volatility and downturn in world oil prices, the Tamarind team has continued to look at innovative ways to maintain oil field profitability. To achieve this, Tamarind has acquired the FPSO Intrepid from its O&M provider Rubicon. In turn, Tamarind is leasing the FPSO Intrepid to the Galoc Joint Venture on terms that are mutually beneficial to both parties and most importantly, enable the Galoc JV to continue production and the economic life of the Galoc field.
Workovers are a normal part of any oil and gas company’s business. Like your car, our oil wells need “tuning up” occasionally to maintain optimum production. Tamarind has a regular schedule of workovers, as well as those “surprise workovers” when something breaks downhole. Most of our wells pump the oil from the ground with the help of a pumpjack – the nodding donkeys!
These types of pumps have up to two kilometres of steel rods connecting the donkey to the downhole pump. Those rods wear out going up and down all day, so replacing those rods is one of the common workovers Tamarind schedules. Tamarind is currently pulling and running rods and pumps into two wells on Cheal B site.
There is also further activity planned in early 2021 for maintenance interventions on Cheal B and Cheal E. Rig availability is currently hindered due to restrictions around rig-crew entry into New Zealand due to Covid-19. However, the team are committed to keeping the project moving and will continue to work towards completing the activity when possible. We will keep you updated as things progress!
Whilst the beginning of 2019 saw TNO busy installing a pipeline and constructing a small gas plant for the Supplejack facility, 2020 has been relatively quiet at Supplejack with the pool producing steadily and reliably. The Supplejack gas has been dedicated by FirstGas, the local gas pipeline and transmission company, to singularly supply all the gas to the town of Inglewood on the North Island of New Zealand. Inglewood has a population of about 4000, it makes us proud to know all those people stay warm (or cool), cook their meals, and run their businesses thanks to Tamarind gas.
TNO have recently had some exciting new appointments in the NZ team.

In 2003 Drew accepted the position of President and CEO of TAG Oil Ltd, he was the first employee at TAG Oil and held the positions of President and CEO as well as Chief Operating Officer with the company for over 12 years.
Tamarind NZ Onshore also welcomes new HSE Manager, Brian Rowland and new Finance Manager, Carla Graham.
On January 17th, Tamarind commenced production from the Supplejack field. The Supplejack gas plant and export pipeline were completed within six months of design, development and construction. Gas production from the field will be at 4,000 Mscf/d and is exported via pipeline to the First Gas Network for distribution throughout New Zealand. The project team delivered the facility on time and on budget, with no HSE incidents.
