P1 reserves valuation: Argentina
In accordance with the regulations set forth by the United States Securities and Exchange Commission (“SEC”), future net cash flows were calculated by applying current prices of oil and gas reserves (with consideration of price changes only to the extent provided by contractual arrangements) to estimated future production of proved oil and gas reserves as of the date reported, less the estimated future expenditures (based on current costs) to be incurred in developing and producing the proved reserves. Future net cash flows were then discounted using a factor of 10% per annum.
For the Argentina assets, the proved reserves as of December 31, 2022, were calculated with a price of 72.3$/bbl for oil, 31.2 $/boe for LPG and 3.9 $/MMbtu for natural gas, compared to 54.9 $/bbl, 26.7 $/boe and 3.4 $/MMbtu, respectively, as of December 31, 2021. These prices are assumed flat for the entire valuation in accordance with SEC regulations.
