Surface Controlled Subsurface Safety Valves (SCSSV)

The wellhead control panel (WHCP) is a hydraulic system that utilizes a hydraulic power pack and control module to operate choke and safety valves at the wellhead. It contains valves, regulators, pumps, and accumulators to direct pressurized oil or water-glycol to valves. A typical WHCP arrangement includes reservoirs, pumps, accumulators, solenoids, valves, pressure regulators, switches, and transmitters to control surface controlled subsurface safety valves, surface safety valves, master valves, and wing valves at each well. The WHCP monitors, controls, and allows safe shutdown of wellhead valves to ensure safe unattended well operation.

Wellhead Control Panels (WHCPs) are also known as Shutdown Panels (SDP) Emergency

Shutdown Systems (ESD) Hydraulic Safety Shutdown System (HSSS). These are failsafe shutdown
systems which have pneumatic/hydraulic/electric components; WHCPs can also be integrated
with PLC/ RTU/ SCADA. WHCPs are standalone control systems as well as an interface between
the plant control and the wellhead safety system.

WHCPs are used for monitoring, controlling (Remote/Local) and safe shutdown of Subsurface
Controlled Safety Valves (SCSSV), Surface Safety Valves (SSV), and other wellhead safety valves
(Choke, ESD, HIPPS) in oil & gas production fields to ensure safe operation of unattended
wells/platforms.

WHCPs may have multiple applications, which include, but are not limited to

• Safe and Sequential Operation of Wellhead Valves (SCSSV/SSV/Wing Etc.)


• Emergency and Fire Shutdown
• Safe Operation of Riser Valves
• Flow line Pressure control
• Well Test Operation
• HIPPS /ESD/ Choke Valve Control
• Partial Stroking

• The wellhead control panel (WHCP) is a hydraulic system that utilizes a hydraulic power
pack (pump and accumulators) and a wellhead control module to perform its task. The
output of WHCP is high pressure hydraulic supply and medium hydraulic supply to operate
choke and safety valves. The wellhead control panel is also the interface between the
plant control and the well safety system.
• A typical wellhead control panel contains a system of valves and regulators, situated
topside at the power source, which may be operated manually or by remote control to
direct pressurized mineral oil or water-glycol to final control elements at the
wellhead/Christmas tree.
• A typical arrangement includes - reservoir, pumps, accumulators, solenoids, valves,
pressure regulators, switches, motor control, transmitters and junction boxes. Each well
is typically equipped with:
•
• • Surface Controlled Subsurface Safety Valves (SCSSV) or Down Hole Valves (DHV)
(In most applications, SCSSV is an on-o valve with hydraulic actuators)
•
• • Surface Safety Valves (SSV)
•
• • Master Valves (MV)

• • Wing Valves (WV) (controls production rate)
