Sharing below info to my Instrumentation collegues. Hope this will cover topic for Instrumentation engineer so there will be basic info available with us to design WHCP and can have IDC checks in detail.
Wellhead control panel is composed of hydraulic power unit (HPU), tubing & fitting and instrument valve and electrical control devices. HPU supply hydraulic resource to open and close SSV including MSSV, WSSV and SSSV. WHCP are also known as Shutdown Panels (SDP), Emergency Shutdown Systems (ESD) or Hydraulic Safety Shutdown System (HSSS). These are fail-safe shutdown systems which have pneumatic/hydraulic/electric components; WHCP can also be integrated with PLC/ RTU/ SCADA. WHCP may have multiple applications, which include, but are not limited to Safe and Sequential Operation of Wellhead Valves (SCSSV/SSV/Wing /MV etc.),Emergency and Fire Shutdown,Safe Operation of Riser Valves,Flow line Pressure control,Well Test Operation,HIPPS /ESD/ Choke Valve Control,Partial Stroking.
WHCP for gas well or an oil well that is used to control well for shutdown,casing pressure reading parameters,tubing pressure reading parameters,temperature well parameters,to open or close a Wing Valve (WV), Master Valve (MV), as well as Down Hole Safety Valve (DHSV),pressure switch -Low/Hi Hi,The Fusible plug (for detection of fires & Anti-fire Shut-down ),TG,PG,FG.
The Final element of the system shutdown: DHSV, Down hole Safety valve (driven by hydraulic power), MV, master valve (driven by hydraulic power), SSV (SSV can not be opened unless local reset after shutoff), surface safety valve (driven by pneumatic power),Choke valve, manually operated,SDV (shutdown valve) installed in flow line of well, outside the part of the wellhead (X-mas tree).Valves are a part of which will receive command of the signal to be opened or closed from Wellhead control panel. Relief Valve shall be installed on each hydraulic circuit to prevent high pressure.Regulators are used to provide regulated pressure to downstream oil headers which are used for each supply header.e.g. if some valve requires higher operating pressure then this circuit will have a dedicated regulator and pressure relief valve.
The Problems That Often Arise in Wellhead Control Panel (WHCP) leaking & stucking of 3 way valve components and popping of PSV. Incorrect MOC selection for items used in pneumatic ckt ,O rings etc. may impact due to hydrocarbon service.
Types of WHCP
Single wellhead Control Panel: well head control panel is used for controlling one well Surface controlled sub-surface safety valve (SCSSV), Master SSV and Wing SSV. SSVs can be shutdown automatically and manually by WHCP to response all kind of emergency situation.Single well control panel is categorized the following system according to driven resource: Manual control system, Electrical control system, Pneumatic control system, Solar powered control system.
Multi-wellhead Control Panel:Each control module can be inter-replaceable without any interruption of other well operation. Common module include oil reservoir, Pneumatic hydraulic pump and standby manual pump.Main function shows as following: Remote RTU shutdown; Fire fusible plugs protection, Low pressure / high pressure sensing, Manual control at panel.Each control module is built up dedicated for one well only. Therefore if there are 5 well in a wellhead platform, then there will be 1 basic cabinet and 5 wellhead control module needed.In general the SCSSV will operate at high pressure rating and SSV will operate at medium pressure rating. Thus there will be two hydraulic headers at WHCP with its own hydraulic pump. The hydraulic pump can be pneumatic driven or electric driven depends on criticality and operation area. All hydraulic pump suction will have a strainer to filter the hydraulic fluid from any particulate so that the hydraulic fluid goes to SCSSV or SSV is clean. To make the hydraulic demand from SCSSV or SSV achievable, the downstream of the hydraulic pump (hydraulic header) is equipped with an accumulator. Accumulator sizing is done such that it allows two complete cycles of opening and closing of all wellhead valves without the requirement of pumping. Accumulators are pre-charged type,Based on the isothermal compression and expansion of the nitrogen pre-charge gas, the effective gas volume required is calculated.Accumulators are placed in WHCP hydraulic circuits to supply pressure in case oil pressure is not available.It helps the hydraulic pump to supply quickly the hydraulic demand. This arrangement (reservoir, hydraulic pumps, and accumulator) usually is called as a hydraulic power pack or a hydraulic power unit.After the hydraulic fluid accumulated at the hydraulic header (both high pressure and medium pressure) then it’s ready to supply each wellhead control module. Usually the line from hydraulic header to wellhead control module is called a hydraulic supply lines. At this wellhead control module, the sequence and logic to operate the SCSSV and SSV is built up. The ESD signal mainly also goes to this module. When it needs to open the SCSSV and SSV, it supplies the high pressure or medium pressure hydraulic fluid to the SCSSV and SSV. In case there is a need to close it down, the hydraulic fluid supply will close and the hydraulic fluid will goes to a hydraulic return line through a three way valves selector. This hydraulic return line will goes to the hydraulic reservoir again.
From this general explanation we can conclude that the wellhead control panel (WHCP) is a hydraulic system that utilizes a hydraulic power pack and a wellhead control module to perform its task. The material of WHCP should be SS316/L and should have IP 65 protection class, and sunshade/canopy for outdoor installation.The WHCP panel is installed in the field near the well pad and it does not contain any controller part. PLC/RTU panels can be installed in a safe field area or in a controlled environment. Wallpapers for mac 2017. Normally, Remote I/O panels are installed in the field for oil well-related operation interfaces.
Instrumentation interface:Pressure Transmitters and local pressure gauges are required on the Hydraulic headers for local monitoring and status indication of valves.Level transmitter and LG are required to monitor reservoir level.Solenoids are installed in hydraulic supply headers to valves. Once solenoids are energized hydraulic oil will pass through the solenoid and goes to valve actuators.Pushbuttons/selector switches for the Christmas Tree valves local/test/remote operation SSSVs, SSVs, UMVs, WVs.Open/Close status indication lamps for the SSVs, SSSVs, UMVs, and WVs, etc.Junction boxes for interconnection between WHCP and PLC/Control system (Pressure, Level, solenoids, or Control valve, start/stop of hydraulic pumps, status indication/local operation interfaces, etc)
In short WHCP is designed to provide the necessary hydraulic pressure to hold all Wing Valves (WV), Master Valves (LMV & UMV) and Sub-Surface Safety Valves (SSSV) in the open position under normal conditions and to close these valves under abnormal / trip conditions.
