PETROTAL RESUMES BRETANA DEVELOPMENT DRILLING, SPUDS WELL 25H AHEAD OF SCHEDULE

Petrotal Corp. has provided the following operational update. All amounts are in U.S. dollars unless stated otherwise.

Key highlights:

• Development drilling resumes with spudding of well 25H, paving the way for expected material production growth;
• Bretana water injection capacity increases to 190,000 barrels per day following stimulation campaign;
• Total group production averaging 12,286 barrels of oil per day in the month of September, an increase of approximately 600 barrels of oil per day month over month.

Manuel Pablo Zuniga-Pflucker, president and chief executive officer, commented:

"I am very excited to announce that we have spud the 25H development well, our first new well at Bretana since January, 2025. The resumption of development drilling at Bretana is the culmination of months of hard work from our entire team and represents the first step in restoring our production base to a sustainable plateau of approximately 20,000 barrels of oil per day. With a drilling inventory of 22 locations remaining to fully exploit Bretana 2P reserves of 106 million barrels, I am confident that Petrotal is on the path to unlocking the full value of the Bretana field."

Bretana 25H drilling update

At 7 p.m. local time on Monday, Sept. 21, 2026, Petrotal formally commenced the next phase of its development drilling program at Bretana, spudding the 25H horizontal well approximately one week ahead of schedule. This will be the 20th horizontal well that Petrotal has drilled at the Bretana field and the first well using the higher-spec Estrella 2027 drilling rig. Consistent with horizontal development wells previously drilled at Bretana, the 25H well will be drilled to a measured depth of approximately 4,300 metres, targeting the producing Vivian formation at a vertical depth of approximately 2,700 metres. The 25H well is expected to take approximately eight weeks to drill and complete, at a total cost of $15-million. Petrotal will continue to provide updates on drilling progress as necessary.

Block 95 operations update

As disclosed previously, Petrotal recently conducted stimulations on two water injection wells at the Bretana field. Since the operations were completed on Sept. 3, 2026, water injection capacity at the Bretana field has averaged just over 190,000 barrels per day, an increase of 9 per cent compared with the August, 2026, monthly average. These efforts are part of a larger, continuing initiative to increase the Bretana field's water injection capacity to a total of 320,000 barrels per day by the end of 2028. Supported by the improvements in injection capacity, Bretana field production has averaged 11,960 barrels of oil per day in September, an increase of approximately 600 barrels of oil per day compared with the prior month. Petrotal's total group production is averaging 12,286 barrels of oil per day thus far in September.
