Increasing productivity in a deepwater pre-salt reservoir
A deepwater pre-salt carbonate field development required increased productivity in a technically demanding environment. The well was drilled at 1,400 m / 4,600 ft water depth with a 40° inclination and an 89 m / 293 ft open-hole interval in a carbonate reservoir with significant permeability variance.
The operator needed a stimulation solution capable of delivering higher productivity than conventional methods.
Precise reservoir stimulation with branching technology
Fishbones deployed a 5½” liner equipped with six Fishbones Jetting Subs, creating a total of 24 branches into the reservoir.
To simplify operations and reduce complexity, acid was pumped directly from the rig without the need for a dedicated stimulation vessel.
Safe and Successful Execution
The operation was completed safely and according to plan in a challenging deepwater environment.
Significant Stimulation Effect
Strong stimulation effects were observed during the Fishbones Jetting process, improving reservoir connectivity and productivity potential. Acid was evenly distributed across the branches proviing even and deep stimulation.
Accelerated Field Development
The successful deployment supported completion of two additional wells in Q1 2026, with production start-up achieved in Q2 2026.
