Abstract
A pressure bleed-off module for an oil well includes: an inlet receiving fluid from an annulus vent of the well; an outlet sending the received fluid to a kill valve of the well; and two paths coupled in parallel between the inlet and the outlet. Each path channels a flow of the received fluid from the inlet to the outlet and includes: a pressure relief valve dividing the path into an inlet side coupled to the inlet and an outlet side coupled to the outlet, opening when the pressure of the fluid in the inlet side exceeds a threshold, and closing when the inlet fluid pressure is below the threshold; pressure gauges measuring the inlet fluid pressure and the pressure of the fluid in the outlet side; a pressure recorder recording the measured inlet and outlet fluid pressures; and a sampling point for draining the fluid in the outlet side.
