Alvopetro reports record gas output from Murucututu 183-D4 well, advancing Caburé field development and evaluating infrastructure upgrades for capacity.
Alvopetro Energy Ltd. has released initial production figures from its recently completed Murucututu 183-D4 well in Brazil, where the company holds a 100% working interest. The results highlight record levels of daily natural gas production from the Murucututu asset, underscoring the company’s growth strategy and reinforcing the long-term vision for the field.
The 183-D4 well, drilled in the second quarter of 2025, reached a total measured depth of 3,072 metres. Positioned 106 metres structurally higher than the 183-A3 well, which has been producing since the fourth quarter of 2024, the new well confirmed the presence of natural gas pay zones within the Caruaçu Member of the Maracangalha Formation. Cased-hole gamma ray logs and gas readings obtained while drilling indicated an aggregate of 61 metres total vertical depth of potential natural gas pay, encountered between 2,439 and 2,838 metres TVD.
Completion operations were carried out across seven intervals. Following a 116-hour cleanup period, the well successfully recovered 2,620 barrels of completion fluid and 132 barrels of natural gas liquids. Subsequent flow testing over 70 hours on a constant 32/64” choke demonstrated an average flow rate of 162 e3m3/d (equivalent to 5.7 million cubic feet per day or 953 barrels of oil equivalent per day), at a flowing wellhead pressure of 1,401 psi. During this test phase, an additional 995 barrels of completion fluid and 174 barrels of natural gas liquids were recovered, while condensate output averaged 60 barrels of oil equivalent per day. The final hour of testing recorded a flow rate of 161 e3m3/d (5.7 MMcfpd, 947 boepd) with a pressure of 1,384 psi. Approximately 12,190 barrels of the total 15,806 barrels of completion fluid remain to be recovered.
Given these robust initial results, current production from the Murucututu field is being sourced from the 183-D4 well alone, due to existing facility capacity constraints. The company is now assessing options to enhance infrastructure capacity, which would allow for increased output from Murucututu.
In addition to progress at Murucututu, Alvopetro has advanced development activities within the unitized area that includes the Caburé field. Four wells, representing 2.2 net wells, were drilled during the second quarter, and completion programs have recently begun. Production from these development wells is expected to come online by the end of the third quarter of 2025. These wells are designed to extend the production plateau of the Unit and contribute to future working interest redeterminations. Plans for a fifth development well (0.6 net) remain contingent upon receiving regulatory approvals.
Alvopetro’s continued success at Murucututu and the progress within the Caburé field development program reinforce its position as a key independent operator in Brazil’s natural gas sector.
