Annulus pressure build up during well start up or due to leaks or gas venting is common. Annulus
pressure, if not managed carefully, can collapse or burst tubular strings, exacerbate integrity issues or damage ESP cable (ED). Effective bleed off rate control using subsea or dry tree valves is almost impossible and requires human intervention.
Petroleum Technology Company’s (PTC) SaveFlo bleed off valve provides automatic pressure relief with bleed off rate control.
