Further Reserves Update



Nostra Terra (AIM: NTOG), the oil & gas exploration and production company with a portfolio of development and production assets in Texas, USA, is pleased to provide an update regarding its recently published Reserves, both in terms of presentation and the effects of the current oil price.





·    $68.5 million Future Net Income (total proved), assuming $75 flat oil price

189% increase from value reported on 29 Sep 2021

·    $22.5 million NPV10 (total proved), assuming $75 flat oil price

113% increase from value reported on 29 Sep 2021




Nostra Terra updated its reserves ("Reserves"), using a third-party engineer APN Energy ("APN"), effective 1 September 2021 and as announced on 29 September 2021. The reserves report was prepared by APN for the Company for submission to support its Senior Lending Facility ("Facility"). The increased size of the Facility to $10 million and Borrowing Base (funds immediately available for use) to $2.35 million, are supported by the increased reserve value, Future Net Income ("FNI") and Net Present Value ("NPV") using the bank's price deck. These are typically a more conservative position compared to actual oil prices.


The Company has engaged APN to produce updated figures to reflect the current increase in commodity prices, as well as providing a breakdown of each area of US operations. These calculations use a flat $75 oil price, as detailed below, and seek to show the cashflow benefit the Company could get from stable oil prices at the levels currently being experienced.


The size of the Facility and Borrowing Base will be reassessed at least twice yearly. The Board anticipates the Facility and Borrowing Base will increase with increased oil production, oil prices, and could be further increased should the Company hedge any of its production, there are currently no hedges in place.



Reserves Value Increase

Net incomes are defined as the portion of gross revenues attributable to Nostra Terra's interest after deducting all shrinkage and royalties, and are displayed in the following table. For comparison tables are presented using the bank's oil price curve reported in the 29th September announcement and a $75 flat oil price, both with a 10% discount factor.

Matt Lofgran, Nostra Terra's Chief Executive Officer, said:


"We have a very strong asset base, with a diversified portfolio. We're able to maintain low operating cost in the field so an increase in oil prices provides a tremendous improvement in income and net cashflow, as demonstrated with the 189% increase in Future Net Income.


Our immediate focus is on increasing production and cashflow. We look forward to updating the market shortly with an operations update, including plans for the remainder of the year."

Proved Reserves - Proved Reserves are those quantities of petroleum, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations. If deterministic methods are used, the term reasonable certainty is intended to express a high degree of confidence that the quantities 10 will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will equal or exceed the estimate.
