Material Changes Versus the Prior Comparable Period
- Total proved reserves increased by 70.0 MMboe, or 39%, from 181.6 MMboe to 251.6 MMboe.
- Reserve additions of 87.8 MMboe substantially exceeded 2022 production of 17.7 MMboe, producing a 495% total reserve replacement ratio.
- Bajada del Palo Oeste reserves increased 20%, supported by 20 wells tied in during 2022 and the addition of 32 proved shale oil well locations.
- Aguada Federal added 37.4 MMboe of proved reserves following the tie-in of six wells and the addition of 40 proved shale oil well locations.
- CS-01 reserves declined from 4.5 MMboe to 4.0 MMboe because of 0.2 MMboe of production and a negative 0.3 MMboe revision.
- Q4 and full-year production increased materially, led primarily by growth in Bajada del Palo Oeste, Aguada Federal, and Bajada del Palo Este.
Outlook, Commentary, Risks, and Unusual Items
Management characterized the results as evidence of continued organic and profitable growth from Vista’s Vaca Muerta acreage. The reserve increase was attributed to strong productivity in Bajada del Palo Oeste and the ramp-up of Aguada Federal.
Vista identified up to 550 additional well locations in Bajada del Palo Oeste and up to 150 in Aguada Federal. The filing does not provide formal production, revenue, earnings, or capital-spending guidance.
Reserve valuations use SEC methodology, current reserve prices held flat throughout the valuation period, estimated future production, current development and production costs, and a 10% annual discount rate. Argentina’s valuation used oil prices of $72.3/bbl, LPG prices of $31.2/boe, and natural gas prices of $3.9/MMBtu, compared with $54.9/bbl, $26.7/boe, and $3.4/MMBtu in 2021.
Actual results may differ from forward-looking statements because of operational, geological, economic, regulatory, commodity-price, cost, and other risks. The reserve estimates were prepared by DeGolyer and MacNaughton based on reports dated January 30, 2023.
Investor Verification Checklist
- Verify the independent reserve reports and the assumptions underlying the 251.6 MMboe proved-reserve estimate.
- Assess the sensitivity of future net cash flows to oil, gas, LPG, cost, production, and discount-rate assumptions.
- Confirm the pace, economics, and funding requirements for drilling in Bajada del Palo Oeste and Aguada Federal.
- Review Vista’s related annual report and subsequent filings for revenue, profitability, cash flow, debt, liquidity, and capital expenditure information not included in this 6-K.
- Monitor operational, concession, regulatory, infrastructure, commodity-price, and Argentina- and Mexico-specific risks.
