Flowhead for the well testing
Surface control equipment for drillstem test is necessary compostion of set of tools used for string formation testing
which consists of flowhead (swivel control head), swivel manifold, choke manifold, indication head, data head,
emergency shut-off safety valve, ESD control system, oil and gas diverting manifold etc.
Solid Block flowhead incorporates a solid block valve body, an upper swabbing valve, a kill line valve and a hydraulically actuated flow line valve.
Located below the main valve block is a high axial thrust tubing swivel that allows tool string rotation during operations while under pressure. All valves in this system are magnum gate valve that provide metal to metal sealing.
Flowhead includes a high temperature model to 400oF; additional actuators for other vaves. Hand pump or hydraulic control unit; wireline cutting mechanism in swab valve and valve trim options
Modular flowhead is a lightweight surface control head designed for use in testing, perforating and wireline operations.
Upper and lower units are coupled with a load bearing quick union for easy assembly and disassembly. Components include a hadling sub, upper swab gate valve, remote safety valve, flow line and kill line outlets. Optional equipment includes hand pump or hydraulic control unit, wireline cutting mechanism in swab valve, wireline adapter and transportation basket.
