Monumental Energy Corp. Provides Update on New Zealand Operations

In This Article:

VANCOUVER, British Columbia, February 11, 2025--(BUSINESS WIRE)--Monumental Energy Corp. ("Monumental" or the "Company") (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to provide positive updates on its investment and partnership with New Zealand Energy Corp. ("NZEC") (TSXV.NZ).

As reported by NZEC on February 11, 2025:

TARIKI-5A

NZEC confirms that the recently completed Tariki-5A well has intersected the target Tariki sands, 11-metres higher than previous wells, confirming significant remaining free gas and condensate up-dip in the field. The quality of the 55-metres of net sand confirms Tariki's viability as a gas storage field, with updates on reserves and forecasts currently in progress. Work is in progress to update the associated reserves and associated forecasts.

Initial flow rates from the well were below expectations due to technical challenges which include liquid loading in the 3 ½" tubing and difficulties in managing liquids slugging at Waihapa after ~30km of pipeline. While rates more than 4mmscf/d have been seen, stable rates have been approximately 1 mmscf/d with 25 to 30 bbls/d of condensate (100%). Efforts are underway to increase production.

GAS STORAGE DEVELOPMENT

To expedite the high-value storage phase of the Tariki field, NZEC is moving forward with designing the first stage of the injection & extraction gas storage project, centered around wells Tariki-5A and Tariki-1A. This initial phase will lay the groundwork for the comprehensive storage project, offering early gas storage solutions to customers before the development of the second and third stages. The specifications for Stage 1 are still being defined, but the goal is to achieve injection rates of 10 to 15 mmscf/d and extraction rates of approximately 30 mmscf/d. The majority of the infrastructure needed for Stage 1 is already established, except for the final stage compression at the well site. It is anticipated that an existing mobile unit at the Waihapa Production Station can be adapted to meet the wellsite compression requirements.

The transformation of the depleted Tariki Gas Field into a gas storage facility closely follows the model set by the conversion of the neighboring Ahuroa Gas Field more than a decade earlier. Both fields are situated within the over-thrust structure of the Tariki Sandstone at comparable depths. The Tariki Gas Field, which originally produced around 50 Bscf of gas, is now estimated to have the capacity to safely store between 25 and 40 Bscf of gas.

The Ahuroa Gas Storage facility, with a capacity of approximately 18 Bscf, was sold as a working facility by Contact Energy Ltd. To Gas Services New Zealand Ltd in late 2017 for NZD 200 million. It is important to note that the capacity at Ahuroa is fully contracted to two parties. Following the sale of Ahuroa, there has been a significant increase in gas prices in New Zealand—from approximately NZD 6.40/mscf at wholesale in late 2017 to over NZD 14/mscf in January 2025. Additionally, the seasonal price volatility has intensified, with prices peaking at over NZD 40/mscf during the winter of 2024. This escalation underscores the growing necessity for expanded gas storage capacity.
