• Aruchara-5 successfully drilled to a total depth of 9,097 feet, hitting the H1 target as designed and passing through the H2, H3, H4, H5 and H6 zones, with all zones showing positive results of gas at the surface and through wireline logs
• Aruchara-5 has been completed and connected to the central processing facility and an evaluation of well performance is underway through the CPF with new gas volumes being sold into the Colombian marketplace
• Initial production from the H1 target has come up to 11.0 MMcf/d gross (8.8 MMcf/d net) with a THP of 1600 psi with a choke of 32/64
• Total field production at Maria Conchita has increased to 18.0 MMcf/d gross (14.4 MMcf/d net) following the addition of Aruchara-5, bringing combined Company net production across both Maria Conchita and Sinu-9 to approximately 23.2 MMcf/d
• The work program at Maria Conchita through year-end includes a well intervention at Aruchara-3, a workover at Aruchara-1, and planning of the Aruchara-6 development well

NG Energy International announces the results from the drilling of the Aruchara-5 well at the Maria Conchita Block (80% working interest) and subsequent work program at Maria Conchita for the remainder of 2026.

Aruchara-5 Well Drilling Results

The Aruchara-5 well has been successfully drilled to a total depth of 9,097 feet, hitting the H1 target as designed and passing through the H2, H3, H4, H5 and H6 zones, with all zones showing positive results of gas at the surface and through wireline logs. Aruchara-5 has been completed and connected to the central processing facility at Maria Conchita (the “CPF”) and an evaluation of well performance is underway through the CPF, with new gas volumes being sold into the Colombian marketplace.

Initial production from Aruchara-5 has delivered rates of 11 MMcf/d gross (8.8 MMcf/d net) at a wellhead pressure of 1,600 psi across the H1 zone. The addition of Aruchara-5 has brought total field production at Maria Conchita to 18 MMcf/d gross (14.4 MMcf/d net). Combined with average gross daily production of 22.5 MMcf/d (8.8 MMcf/d net) at Sinú-9 since Hechicero-1X was brought online, total Company net production is approximately 23.2 MMcf/d.

The Company’s contracted offtake agreements at Maria Conchita cover volumes up to 15 MMcf/d gross, with all incremental volumes above this threshold being sold into the Colombian spot market at approximately US$11.50/Mcf. At Sinú-9, the Company maintains contracted offtake agreements up to 25 MMcf/d gross, with all incremental volumes above this threshold expected to be sold into the Colombian spot market at approximately US$13.00/Mcf. Both fields benefit from a structurally premium Colombian natural gas pricing environment, with spot pricing upside expected to increase as combined Company production scales through the remainder of 2026.

Maria Conchita 2026 Work Program

With Aruchara-5 now connected and producing, the Company is advancing a comprehensive work program at Maria Conchita through the remainder of 2026, which is designed to optimize production across the field and sustain capacity growth:

• Aruchara-3 – Well Intervention: a sand cleanup operation is planned to optimize and increase production rates from Aruchara-3, while also advancing the Company’s understanding of the H4 zone.
• Aruchara-1 – Workover: a workover is planned at Aruchara-1, incorporating sand management to restore and increase production while testing new zones.
• Aruchara-6 – New Well: following the results of Aruchara-5, the Company plans to drill Aruchara-6 as the next development well at Maria Conchita, with spudding targeted in Q3 2026.

The Maria Conchita Block benefits from infrastructure supporting up to 30 MMcf/d gross (24 MMcf/d net) of processing and transportation capacity, providing the runway to monetize production growth from the ongoing work program.

Brian Paes-Braga, Executive Chairman of NGE, commented:
“Aruchara-5 has confirmed productive gas across all six zones from H1 through H6 and is now connected and selling into the market – we are already seeing the commercial benefit of this program. Combined with Sinú-9 averaging 22.5 MMcf/d since Hechicero-1X was brought online, total Company net production has reached approximately 23.2 MMcf/d, with pace of growth increasing into the second half of this year as Maurel & Prom advances the six-well campaign at Sinú-9 and we execute our expanding work program at Maria Conchita. With Aruchara-6 on the horizon and a fully funded program in place through year-end, NGE has never had a more active operational program than it does today.”
