MARIA CONCHITA ENVIRONMENTAL LICENSE MODIFICATION GRANTED TO INCLUDE ARUCHARA-1

VANCOUVER, BC, March 3, 2022 /CNW/ - NG Energy International Corp. ("NGE" or the "Company") (TSXV: GASX) (OTCQX: GASXF) is pleased to announce that the National Authority of Environmental Licenses ("ANLA") has granted the amended environmental license for Maria Conchita to include the Aruchara-1 well. This is a transformational milestone for the Company as it permits production from the Aruchara-1 well and allows NGE to lay the remaining 40 meters of flow line connecting the well to the gas plant. It also enables the Company to complete the connection point to the Transportadora de Gas Internacional ("TGI") main pipeline which will transport natural gas from Maria Conchita to market.

Further to the Company's press release on January 18, 2022, the Company has made significant progress with low-pressure, mid-pressure and high-pressure nitrogen testing of the gas plant facilities after which NGE will begin testing the facilities with natural gas once the Aruchara-1 wellhead is connected to the plant in the coming days.

The amended license authorizes NGE to commence extended well testing at the Aruchara-1 well in order to evaluate the productivity and characteristics of the reservoir, and define the best production method for achieving maximum recovery from the field. Gas used for pressure testing will be flared and once complete, gas produced during extended testing will be commercialized.

As per the Company's press release on August 31, 2020, the Aruchara-1 well was successfully re-entered and tested 7-11 million standard cubic feet per day (MMSCFPD) per zone across 3 different zones through separate drill string tests (DST) with a 48/64" choke. Management expects production to be between 16 and 20 MMSCFPD.
