Pragma has completed a systems integrations test on both size variants of its new Slim Pump Safety Valve (SPSV), to demonstrate its efficient and reliable operation under field simulated conditions, in advance of field deployment.
Pragma’s advanced SPSV technology is designed to be retrofitted to mature or depleted wells, in-line with a cable-deployed electric submersible pump (CDESP), to deliver enhanced operational safety.
The tests were conducted by Zilift at their purpose-built facility in Aberdeen, utilising a Zilift cable-deployed ESP in-line with the SPSV, within a test and validation flow loop. A range of tests was performed to ensure that both SPSV variants, a 2.625” and a 3.19” sized valve, functioned in synergy with the ESP. The SIT provides additional customer confidence and performance data and supports the product’s API 14A qualification, which was awarded in 2020.
Both valves opened within seconds of the ESP’s activation, ensuring no cavitation or overheating of the pump occurred. The valves quickly closed again on the shut-down of the ESP. During continued operation, no impact on ESP performance was witnessed. Zilift personnel conducted pump-curve tests to fully validate the SPSV with their ESP technology. This work ensures the SPSV is fully prepared for commercial deployment in the North Sea and the Middle East.
