Abstract
A fluid conduit defines a fluid passage from a well annulus to a venting system. A first pressure safety valve is positioned within the fluid passage. The first pressure safety valve is configured to open at a first set pressure. A second pressure safety valve is fluidically connected in series with the first pressure safety valve. The second pressure safety valve is configured to open at a second set pressure.
Claims20
A pressure relief system comprising:
- a fluid conduit defining a fluid passage from a well annulus to a venting system;
- a first pressure safety valve positioned within the fluid passage, the first pressure safety valve configured to open at a first set pressure;
- and
- a second pressure safety valve fluidically connected in series with the first pressure safety valve, the second pressure safety valve configured to open at a second set pressure.

A method comprising:
- receiving an increase in pressure, by a valve disk, within a fluid conduit defining a flow passage fluidically coupled to a well annulus;
- and
- lifting the valve disk of a first pressure safety valve responsive to the received increase in pressure.
A system comprising:
- a wellbore comprising an annulus defined by a wellbore casing and production tubing;
- and
- a safe venting system comprising:
- a fluid conduit defining a fluid passage from a well annulus to a venting system;
- and
- a poppet-style pressure safety valve positioned within the fluid passage, the poppet-style pressure safety valve configured to open at a set pressure.
