Flowhead / Well Testing Surface Test Tree For Well Testing Flow Control

The Flowhead is the surface test tree for wellhead flow control. The flowhead is the primary device for controlling the well and allowing the introduction of wireline.The standard valve configuration of the flowhead is four valves arranged in a cross shape. The bottom valve is a manual valve and is commonly known as the Master Valve and is the valve normally used to isolate the well bore from the surface process facilities. The top valve, which is also a manual valve, is known as the Swab valve and is used to allow the introduction of wireline tool strings into the well-bore. The two side valves are called the Flow-wing valve and the Kill-wing valve. The Flow-wing valve is normally a hydraulically actuated fail-safe close valve, which is activated by means of a control panel, or in an emergency situation, remotely by the ESD system.The basic designed Flowhead includes four valves-Master,Swab,Kill and flowline(Hydraulic actuator). The flowhead assembly also has swivel to allow pipe rotation for manipulating downhole tools(DST String) without turning the test head.
