• Zones H1 + H2 + H4 combined test up to 65.2 MMscf/d
• Completion of Aruchara-3 and redefining the scope and potential of Maria Conchita underway
• Between SN-9 and Maria Conchita, a total of over 130MMscf/d now tested

TORONTO , Sept. 20, 2023 /CNW/ - NG Energy International Corp. (" NGE " or the " Company ") (TSXV: GASX) (OTCQX: GASXF) is pleased to announce the completion of the third Drill Stem Test (DST-3) at the Aruchara-3 well in the recently identified H4 Zone of the Jimol Medium Formation. DST-3 was conducted over a 42-hour period including 28-hour after flowing period, testing up to 25 MMscf/d at a 1.5" choke.

The complete results for DST-3 are as follows:

With the testing of the H4 Zone, and due to the similarity between the H3 and H4 Zones, it was determined to leave the H3 Zone for future testing as the results of the H4 Zone can be extrapolated to the H3 Zone. The Company can conclude that a more than 1,200 foot naturally fractured section is present, which includes the presence of gas and condensate, redefining the scope and potential of the Maria Conchita field. The Company is in the process of completing the Aruchara-3 well to define optimal production and it is anticipated that the Company will reach full capacity of the production facilities, estimated at 20 MMscf/d, in Q4 of this year.

Serafino Iacono , Chief Executive Officer of NGE, commented: "The Aruchara-3 well has exceeded all the expectations the Company had when we began drilling this well, with the greatest initial production rates I have seen over the course of my career. The newly encountered H3-H4 Zones have the potential to dramatically increase Maria Conchita's reserves and resources and redefine the size and potential of this field. The Company intends to revisit Aruchara-1, Aruchara-2, and Istanbul -1 to verify the potential continuity of this newly encountered naturally fractured zone as part of the re-scoping of the Maria Conchita field. Once completed and tied in, we anticipate reaching the targeted production of 20 MMscf/d. In parallel, we will be evaluating different scenarios to increase pipeline capacity at Maria Conchita. I wish to thank our technical team who have done a remarkable job, working around the clock, to achieve these world class results. We thank our shareholders for their patience and are very pleased to have been able to drill this well so successfully during this critical time for energy security in Colombia ."
