Vista announces successful results in Aguila Mora, and provides operational update

of Bajada del Palo Este, extending well inventory into Coirón Amargo Norte

Mexico City, July 10, 2023 – Vista Energy, S.A.B. de C.V. (“Vista” or the “Company”) (NYSE: VIST; BMV: VISTA) announced today successful results in wells AM-1011h and AM-1012h in pad AM-1, located in Águila Mora block (see map below). Well AM-1011h was landed in La Cocina, with a lateral length of 2,548 meters and 44 completion stages. Well AM-1012h was landed in the Middle Carbonate, with a lateral length of 2,468 meters and 43 completion stages.

The peak production of well AM-1011h was 2,107 barrels of oil equivalent per day (boe/d), while the peak production of well AM-1012h was 1,699 boe/d. Both wells are currently restricted by gas evacuation capacity, limiting well productivity. Additionally, the cumulative production of well AM-1011h for the first 60 days was 79.7 thousand barrels of oil equivalent (Mboe), whereas the cumulative production of well AM-1012h was 70.2 Mboe for the first 60 days, in both cases on a normalized basis (normalized to 47 completion stages). The average oil content of the wells was 71% of total hydrocarbons.

Based on the successful results of these wells, the Company has estimated an inventory in Águila Mora of up to 100 ready-to-drill wells.

The Águila Mora unconventional concession is in the light oil window of Vaca Muerta, covering a surface area of 23,475 gross acres. Lab analysis conducted on the oil recovered from the wells revealed an API gravity of 40 degrees. The block is operated by Vista, which owns a 90% working interest. Gas y Petróleo del Neuquén S.A. (“GyP”), the state-owned oil and gas company of the Province of Neuquén, owns the remaining 10%.

Bajada del Palo Este update and extension of well inventory into Coirón Amargo Norte

In mid-April 2023, the Company tied-in well BPE-2202h, in the southern part of the Bajada del Palo Este block (see map below). The well was landed in La Cocina, with a lateral length of 2,272 meters and 47 completion stages. IP-30 production of the well BPE-2202h was 3,101 boe/d, whereas daily peak production was 3,427 boe/d. Additionally, the cumulative production of the well for the first 80 days was 179.9 Mboe, on a normalized basis. The average oil content of the well was 96% of total hydrocarbons.

Successful results in BPE-2202h have enabled Vista to reconfirm the addition of up to 150 ready-to-drill wells to the inventory of the block. They have also enabled the Company to validate its geological model for Coirón Amargo Norte, which is the neighboring block to the south (shown on the map above), covering a surface area of 26,598 gross acres. Coirón Amargo Norte is a conventional concession where the Company holds an 85% working interest, with the remaining 15% held by GyP. Vista’s model indicates the Company has an inventory of up to 50 ready-to-drill wells in this block.

The successful activity in Bajada del Palo Este and Aguila Mora pilots led to the addition of 300 wells to the Company’s inventory, for a total of up to 1,150 wells, distributed as shown in the table below.
