WHCP is instrumentation that controls the flow of fluids from wells. It consists of valves, pressure regulators, gauges, switches, etc. WHPCs are used to watch and manage the oil and gas produced from wells. They are inaugurated at the top of the wellhead and can be both either manual and automatic. A manual WHCP has a group of valves that can be opened and closed manually. An automatic wellhead control panels has a valve system that opens automatically when the pressure reaches a certain level.
The wellhead, also known as a Christmas tree, is an assembly of many spools and fittings. It is usually equip with four to five types of hydraulic valves. The WHCP performs the sequential opening and closing of these hydraulic valves. These valves are:
- surface controlled subsea protection valves or Down Hole valve
- Surface Safety Valves (SSV) are made up of the subsequent valves.
- Master valves
- Wing valves
The manual operation of the lower master valves is possible, while hydraulically-actuated control of the upper master valves is more common. The flow wing is the right-most wing valve. It is also known as the production wing valve because it is located in the flow path for hydrocarbons being taken to production facilities. The kill wing valve, located on the left-hand side of the wing, is used to inject fluids such as corrosion inhibitors.
Hydraulic valves for hydraulic tree need to be under active hydraulic pressure.
Keep your eyes open. WHCP should be position roughly 100 meters away from the wellhead. The Hydraulic or pneumatic outputs from the panel are connect to the wellhead via appropriately size tubes. There are multiple kinds of WHCP
- Electro/hydraulic WHCP
- Pneumatic/hydraulic WHCP
- Modular multi-well WHCP
- Solar power WHCP
- PLC based electro-hydraulic WHCP
Fluid flow happens when a fluid shifts from a high-pressure province to a low-pressure province. When this happens, energy is release. Energy is release through friction between molecules. Friction causes heat. Heat can cause expansion, contraction, or boiling. Boiling is what we use to produce steam. Steam is then turn into electricity using turbines.
Sections for electrical appliances
This section provides the electric power needed to produce the hydraulic power necessary for the operation of the whole system.
Hydraulic power unit
This section covers the hydraulic power generation required to operate the valves at the WH that allow the crude oil to flow out. The following components are involve in the same.
A hydraulic reservoir
It provides enough oil to power a wellhead. It is usually an atmospheric tank with flame-arrester venting. The dimensions of the tank will deviate depending on safety measures and parameters.
The flow can be control electrically and then follow by a non-returning valve to direct the flow in one direction.
To remove oil from the reservoir.
To ensure that the hydraulic demand from valves is meet and to quickly lead pump supply. Facilitate local monitoring, control, and control; pressure and level gauges, transmitters, and switches are available.
To provide steady, regulated pressure for each hydraulic loop.
Pressure relief valves
To prevent overpressure.
This division is the brain of the system. The design and parameters of the actuators are important.
Chemical injection system (CI)
The production team will pick the chemical to inject for the Chemical injection system. The tank is filled with reciprocating pumps that are set up according to the process.
The oil & gas engineering company is one of the largest industries in the world. There are many different types of wells. Some of them include water wells, coal mines, and natural gas wells. These wells have been around since ancient times. Wells are drill into rock formations to extract oil and gas. This is how fuels are obtain.
WHCPs is a key piece of equipment in the oil & gas industry. The wellhead system is the point where tubing strings and casing ends. These systems regulate pressure and allow access to the main bore or annulus of tubing strings or casing.
