NG ENERGY TESTS 23.5 MMSCFD IN THE H2 ZONE AT MARIA CONCHITA

• Zones H1 + H2 combined test up to 40.2 MMscf/d
• Between SN-9 and Maria Conchita, over 105mmscf/d now tested

TORONTO, Sept. 18, 2023 /CNW/ - NG Energy International Corp. ("NGE" or the "Company") (TSXV: GASX) (OTCQX: GASXF) is pleased to announce the completion of the second Drill Stem Test (DST-2) at the Aruchara-3 well in the H2 Zone of the Jimol Inferior Formation. DST-2 was conducted over a 46-hour period including a 17.5-hour flowing period, testing up to 23.5 MMscf/d at a 1.5" choke with 5.3 barrels of 43.5 API condensate recovered during the test.

The complete results for DST-2 are as follows:

The Company is currently testing the upper zone in Aruchara-3 and will be focused on completing the well and bringing online in the coming weeks, in order to fill the capacity of 20 MMscf/d of infrastructure currently at Maria Conchita. Based on the results to date, the company is also re-scoping the potential size of the Maria Conchita field.

Our technical team has achieved 100% success on exploration and development wells between Maria Conchita and SN-9 with over 105 MMscf/d of combined gas flow. We look forward to completing this well and bringing it online in the coming weeks as well as updating the market on our progress at SN-9, as Colombia's gas needs have never been more critical."

Abbreviations

The abbreviations set forth below have the following meanings:

"Condensate", also called condensate, gas condensate, or natural gas liquids, is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw gas produced from many gas fields. Some gas species within the raw gas will condensate to a liquid state if the temperature is reduced to below the hydrocarbon dew point temperature at a set pressure. Raw gas may come from any one of three types of gas wells:

(a) Crude Oil Wells: Raw gas that comes from crude oil wells is called "associated gas". This gas can exist separate from crude oil in the underground formation or be dissolved in the crude oil. Condensate produced from oil wells is often referred to as "lease condensate";

(b) Dry Gas Wells: These wells typically produce only raw gas that contains no hydrocarbon liquids. Such gas is called "non-associated gas". Condensate from dry gas is extracted at gas processing plants and is often called "plant condensate"; and

(c) Condensate Wells: These wells produce raw gas along with NGLs. Such gas is also called "associated gas" and is often referred to as "wet gas".
