... installation. The first solution requires significant rig expense, and the second can cause loss of downhole safety-valve functionality. A more cost-effective, safer problem resolution method was needed. This paper describes the first ENI field trial of a Capillary Deliquification Safety System that can...

... In order to channel the fluid from the new internal control line into the control section of the safety valve a component called the "POD" was designed (see Fig. 3 ). This incorporates a concentric control line inlet which is channeled to the rod piston with no significant impact...

... tubing pressure is added into the required opening pressure of a valve, designers look at ways to eliminate tubing pressure sensitivity from the equation. In the past, this has been done with nitrogen-charged safety valves. In these valves, the operating piston is operated by control fluid from...
