Monumental Energy: Copper Moki-2 Well Workover Complete, Commercial Production Resumes in New Zealand

VANCOUVER, British Columbia – New Zealand’s Taranaki Basin is about to see a revitalized player in the oil and gas game.
Monumental Energy Corp. (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) today announced the successful completion and resumption of commercial production at its Copper Moki-2 (CM-2) well, signaling a promising return on investment in a region ripe with opportunity.

Copper Moki-2 well in production

The CM-2 workover aimed to revive production from the Mt. Messenger sands, tackling flow restrictions. Furthermore, the project saw the perforation and testing of previously untapped hydrocarbon zones. This approach is expected to lead to increased production, and early data are very encouraging, demonstrating that the new pump is running smoothly.

The firm has perforated three new intervals at CM-2, which are expected to bolster the well’s output, especially in the early production stages. Initial feedback suggests that the new pump is meeting expectations, with around 300 barrels of brine – previously used to maintain pressure – successfully pumped out.

The workover of Copper Moki-1 (CM-1) is poised to start in roughly 10 days. If successful, CM-1 will be on continuous production alongside CM-2. “We are very enthusiastic about the expected volumes from both wells” noted an industry watcher. The market anticipates considerable production from both wells once these are fully operational.

Interestingly, the context has changed since the discovery of the Copper Moki field. Back then, New Zealand faced a natural gas surplus, with the field isolated from the gas network. Today, it’s fully integrated into the infrastructure, representing a significant revenue stream that was previously unavailable.

CM-1 and CM-2 were originally shut down due to mechanical issues rather than reservoir concerns. The wells merely needed standard maintenance and equipment upgrades to restart production. In 2024, Monumental Energy partnered with NZEC to bring the wells back online, capitalizing on NZEC’s shift toward a gas storage model. Based on the agreement, Monumental Energy will receive a 25% royalty on all oil and gas production from the Copper Moki site, after it has recovered its initial 75% capital investment.

In the Taranaki Basin, oil fetches a small discount to Brent Crude (around USD $77.39, as of June 20). However, the price of natural gas is another story, with figures between USD $11.00 and $15.00 per MCF – significantly higher than in North American markets.

Cumulative insights on production, expressed in barrels of oil equivalent (BOE), will be made available within the coming weeks.

“The Copper Moki wells have a stellar track record,” stated Max Sali, Vice President of Corporate Development and Director. “With about one million barrels of oil already produced, the successful recompletion of CM-2—including the perforation of three new intervals—is expected to amplify the output. We expect strong initial volumes, and the reservoir is recharging nicely. This confirms the Mt. Messenger formation’s productivity, positioning us for immediate cash flow and supporting the long-term value for our investors.”
