The company said that based on preliminary, unaudited financial results, Q4 average production was about 46,500 BOEPD, and full-year 2025 average production was about 45,800 barrels per day.

In Ecuador, Gran Tierra said it produced about 10,000 barrels of oil per day during Q4, with current production at around 8,800 barrels per day. Its Q4 results were affected by an inventory build of about 291,000 barrels of oil in Ecuador, which were sold in early January for roughly $15 million in revenue, the company said.
