(Kaieteur News) – Oil production at Liza One- Guyana’s first petroleum project has fallen from the approved 120,000 barrels a day to under 100,000, according to the latest data published by the Ministry of Natural Resources for the month of June.

This amounts to 20,000 barrels less, which carry an economic value of about US$1.6 million at current oil prices of approximately $80 per barrel.

According to the production data seen by this newspaper, oil extraction has been on a steady decline since the latter end of 2025. ExxonMobil Guyana Limited (EMGL) the operator of the Stabroek Block was granted permission from the Government of Guyana (GoG) to produce above the approved 120,000 barrels per day (bpd) approved in the Environmental Impact Assessment (EIA). As such, the oil giant was producing about 130,000 bpd in average in December 2025. Production dropped to about 120,000 bpd in April and has since been reduced to under 100,000 bpd as of June 2026.
