Material Changes Versus Prior Comparable Period
- Total proved reserves increased by 66.8 MMboe, or 27%, year over year.
- Proved undeveloped reserves increased by 64.3 MMboe, or 39%, while proved developed reserves increased by 2.5 MMboe, or 3%.
- Bajada del Palo Oeste reserves increased 19% to 221.8 MMboe, following the tie-in of 23 new wells and the addition of 40 proved shale-oil well locations.
- Bajada del Palo Este reserves increased to 40.1 MMboe from 8.5 MMboe, driven by two new wells and the addition of 26 proved shale-oil well locations.
- Vista tied in 11 new wells during Q4 2023, contributing to the 14% sequential increase in total production.
- Approximately 5.9 MMboe of reserves booked at year-end 2022 were divested in connection with the conventional-assets transaction.
- Q4 natural-gas production declined 2% sequentially to 1.19 MMm3/d, partly because most newly tied-in wells were in a lower gas-to-oil-ratio area.
Outlook, Commentary, Risks, and Unusual Items
Management stated that development of the Vaca Muerta hub progressed during 2023, highlighting Bajada del Palo Este’s acreage de-risking and the company’s ability to generate organic and profitable growth. The filing does not include explicit 2024 financial or production guidance.
The reserve valuation uses SEC pricing and methodology. For Argentina, the reported prices were $66.5/bbl for oil, $25.4/boe for LPG, and $3.8/MMBtu for natural gas; for Mexico’s CS-01 block, the prices were $68.7/bbl for oil and $2.7/MMBtu for natural gas. Future cash flows are subject to reserve estimates, commodity prices, production performance, development costs, operating conditions, government regulations, and concession terms.
Vista retains 40% of crude-oil and natural-gas production and 100% of LPG production from the transferred conventional concessions until the earlier of February 28, 2027, or specified cumulative production thresholds. The filing includes customary forward-looking-statement risks and refers investors to the company’s Form 20-F and other SEC filings.
Important Facts for Investors to Verify
