Karoon Energy Ltd., Melbourne, is moving to drill two development wells in Patola field in Santos basin offshore Brazil following completion of its third well in the Baúna field intervention campaign.
The company installed a new electric submersible pump in Baúna field SPS-92. It is currently flowing at 9,500 b/d compared to 5,500 b/d prior to the intervention.
Together with the first two well interventions, total oil production from Baúna is near the upper end of pre-intervention expectations at 22,000 b/d.
Considering the results and the small production increment expected from the fourth planned intervention (BAN-1) of a few hundred b/d, Karoon decided to defer the program and move the Maersk Developer rig to development of Patola field.
The first of two Patola development wells will spud the last week of September, marking the company’s first development project since taking operatorship and 100% interest in the Baúna concession in 2020.
The Baúna intervention campaign began in May 2022 after 18 months of planning aimed at installing new down-hole pumps and gas lift equipment targeting an increase in field production up to 10,000 b/d before resumption of natural reservoir decline.
Patola field was discovered in the same BM-S-40 concession by Petrobras in 2011. Karoon made final investment decision in June 2021 to develop the field via two subsea wells, pressure controls, flowlines, risers, umbilicals, and electrohydraulic control equipment tied back to spare riser slots on the Baúna floating production storage and offtake vessel.
Patola, expected on stream early 2023, is expected to add over 10,000 b/d to Baúna concession production prior to natural decline.
