NG Energy Announces Contingent and Prospective Resources in Sinú 9 and Maria Conchita Blocks

VANCOUVER, BC, March 18, 2021 /CNW/ - NG Energy International Corp. (the "Company" or "NGE") (TSXV: GASX) (OTC: GASXF) is pleased to announce the results of the SN-9 and Maria Conchita Blocks from the year-end 2020 resources reports prepared by Petrotech Engineering Ltd.

Highlights:

• NGE confirms best estimate Contingent Resources of 51.4 BCF and best estimate unrisked Prospective Resources of 836.4 BCF for Prospects and 637.4 BCF for Leads at its flagship Sinu-9 block
• NGE confirms best estimate unrisked Prospective Resources of 194.9 BCF and 2P Reserves of 34.6 BCF at its Maria Conchita block

Serafino Iacono, Chief Executive Officer & Director of NGE, stated: "This new resource study exceeded management expectations and confirms our highly prospective natural gas blocks in Colombia as we continue our mission to become one of Colombia's largest and cleanest energy providers. The Company will follow up with a full corporate update in the coming weeks as we push towards initial production from the Aruchara-1 well at Maria Conchita, re-enter and test Instanbul-1 and receive final environmental approval to commence our fully funded 4 well exploration program at the Company's flagship Sinu-9 block."

Results of the Petrotech report are as follows:

SINÚ 9 Block in the Sinú San Jacinto Basin of Colombia

The Company's working interest is 72%, subject to payment of ANH sliding scale royalties.  The effective date of the resources reports is December 31, 2020.  The chance of commerciality for the prospective resources (Prospects) is based on the product of the chance of discovery (geological chance of success) and the chance of development, and is assessed at 30.3% to 31.5%.  No risk has been assessed to the contingent resources and prospective resources (Leads), as the leads have to be upgraded to prospects before risk can be addressed. Due to sparsely shot 2-D seismic data (31 2-D lines of 752 km), there is insufficient data for coverage to map certain closures.  However, the block has 12 wells drilled previously with good geological data for correlation.  The Company would require sufficient funding to fulfill the committed work program and development if any discoveries are made.

NOTE:  the above data should be considered preliminary until necessary analysis or interpretation has been done.  The above test results are not necessarily indicative of long-term performance or of ultimate recovery. 

The contingent resources (Subcategory: Development Unclarified) discussed at the top of this press release have been assigned to these two intervals in the Cienaga de Oro Formation. 

Twelve prospects in the Porquero, Top Ciénaga de Oro and Intra Ciénaga de Oro with five leads have been identified using 2-D seismic data.  These leads will require more information, either additional seismic data and/or drilling data, in order to upgrade the leads to prospects.  There is no certainty that any portion of the resources will be discovered.  If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources.

The Company intends to start an exploration drilling program, subject to receiving the required permits, in Q2 of this year.

Maria Conchita Block in the Guajira Basin of Colombia

The Company's working interest is 80%, subject to payment of ANH sliding scale royalties.  The effective date of the resources report is December 31, 2020.  The chance of commerciality for the prospective resources (prospects) is based on the product of the chance of discovery (geological chance of success) and the chance of development, and is assessed at 20.1% to 21.1%.  The block is covered by 3-D seismic data and would require the identification of geobody facies to locate the gas accumulation which may be challenging. The Company would require sufficient funding to fulfill the committed work program and development if any discoveries are made.

Information Regarding Resources 

This news release discloses estimates of the Company's prospective and contingent resources.  Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development but which are not currently considered to be commercially recoverable due to one or more contingencies. 

Prospective resources are defined in the COGE Handbook as those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective resources have both an associated chance of discovery and a chance of development. Prospective resources are further subdivided in accordance with the level of certainty associated with recoverable estimates assuming their discovery:

• Low Estimate: This is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least a 90 percent probability (P90) that the quantities actually recovered will equal or exceed the low estimate.
• Best Estimate: This is considered to be the best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate.
• High Estimate: This is considered to be an optimistic estimate of the quantity that will actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10 percent probability (P10) that the quantities actually recovered will equal or exceed the high estimate.

Prospective resources are not, and should not be confused with, reserves or contingent resources. Prospective resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of discovery and a chance of development.

There is no certainty that any portion of the prospective resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the prospective resources or that the Company will produce any portion of the volumes currently classified as prospective resources. The estimates of prospective resources involve implied assessment, based on certain estimates and assumptions, that the resources described exist in the quantities predicted or estimated, as at a given date, and that the resources can be profitably produced in the future. Actual prospective resources (and any volumes that may be reclassified as reserves) and future production therefrom may be greater than or less than the estimates provided herein. The accuracy of any resources estimate is a function of the quality and quantity of available data and of engineering interpretation and judgment. While resources presented herein are considered reasonable, the estimates should be accepted with the understanding that reservoir performance subsequent to the date of the estimate may justify revision, either upward or downward.

The resource estimates presented above are subject to certain risks and uncertainties, including those associated with the drilling and completion of future wells, limited available geological and geophysical data and uncertainties regarding the actual production characteristics of the reservoirs, all of which have been assumed for the preparation of the resource estimates.
