Fishbone Stimulation Enhances Tight Carbonate Productivity
The implementation of fishbone stimulation helped to more than double estimated well productivity and tripled the production rate in a tight carbonate reservoir well compared with conventional stimulation during initial testing.
The operator’s first successful installation of fishbone stimulation technology was aimed at establishing vertical communication between layers in a tight carbonate reservoir and maximizing the reservoir contact. Furthermore, the advanced stimulation technology connects natural fractures within the reservoir, bypasses near-wellbore damage, and allows the thin sublayers to produce. This technology requires running standard lower-completion tubing with fishbone subs preloaded with 40-ft needles and stimulation with the rig on site.
The operator plans to develop tight carbonate reservoirs as part of its production growth strategy. Field Q is a 35×15‑km field under development with a phased approach.
