Habu Subsea Tree Cap
The flexible cost reducing Tree Cap
Our multipurpose Scale/Kill/P&A/Dewatering and Well Stimulation Tree Cap System is truly a universal solution.
The world is facing a rapidly increasing number of challenges related to production installations subsea. X-mas tree (XT) problems are likely to occur within 20 years from installation. These could be SCM failures, scale build up in tubing and umbilical hydraulics failures. As a result, production is reduced or even brought to a full stop. The traditional solution has been to replace damaged or run down equipment.
Our SSTC allows double speed scale squeeze operations and significantly cuts cost by up to 30%. Faster scale squeezing and less time-consuming installation makes SSTC a better solution for preventing scale build up and scale removal. SSTC has its own kill system and is designed to reduce operational risk.
Well Stimulation and Scale Squeeze benefits
With Habu Subsea’s SSTC there is no need to retrieve and replace the tree cap for well stimulation. The stimulation package and hose are also installed in one run. This enables faster installation in a weather window, saving time and cost. In addition, our 4” umbilical allows a higher injection rate and shorter stimulation time.
The SSTC is ROV-operated and requires only an IMR DP 2 vessel, significantly reducing the day rates. The equipment is ROV-operated and easy to handle. In comparison it takes no more than two persons to operate where a traditional stimulation job requires eight operators.
