Flowhead 

Flowhead - Surface Test Tree

Flowhead - Surface Test Tree with swivel supports the test string and provides a means of surface well control when completing, testing, or performing live well intervention operations. Two wing valves connect to the kill and flow manifolds to control the flow of the wellbore fluids.

Valve actuators are controlled from a console located on the rig floor and link to the emergency shutdown system for the flow wing valve. This configuration allows for remote shut-in of the well at the flowhead. The handling sub attached to the top of the flowhead valve block is used to tension the flowhead and the riser or landing string.

The handling sub also provides an interface to the surface wireline or coiled tubing equipment. A dynamic swivel is located between the main valve block and the lower master valve, allowing rotation of the string without rotating the flowhead, and preventing any rig movement from transferring torque into the riser or landing string.

Features


Provides at least two surface pressure barriers

Swivel allows rotation of the string without rotating the flowhead

Allows a kill line to be connected for pressure testing, injection, or killing the well

Allows tools to be introduced and run into the well through the swab valve

Comply with API Spec. 6A and NACE MR 0175


Emergency Shut Down (ESD) 

Emergency ShutDown (ESD) System

Emergency ShutDown (ESD) System with a minimum of two remote control stations are recommended for all well test operations. They are designed to pneumatically control the hydraulic flowhead valve or any other single-action, fail-safe hydraulically activated valve and to generate an emergency shutdown signal. The remote stations are to be located at the separator and in an area removed from all pressurized equipment on an escape route. 


During testing operations, emergency shutdown system controls surface safety valve on the flowhead and permits manual or remote closure in response to a pipe leak or break, equipment malfunction, fire, or similar emergency. The ESD system is also used to reopen the valve and, if needed, can control an additional surface safety valve upstream of the choke.

Pressure from the system's air-driven hydraulic pump is applied to open the valves and released to close them.

Test Separator 

3-Phase Test Separator

3-phase test separator is an instrumented pressure vessel designed to efficiently separate well effluent into oil, gas and water for onshore and offshore well testing. The 3-phase test separator can operate as a stand-alone unit or in combination with the surge tank, reducing the dependency on the separation process for high-quality flow measurements.

The 3-phase test separator typically consists of a vessel, an oil flow-measuring system with dual meters, a flow-measuring system for gas, several sampling points for each effluent phase, and two relief valves to protect the vessel against overpressure. Most separators are also equipped to measure water flow rate. To provide accurate measurements, the 3-phase test separator is fitted with pneumatic regulators that maintain a constant pressure and a constant liquid level inside the vessel by control valves on the oil and gas outlets.

The 3-phase test separator is fitted with a deflector plate, coalescing plates, a foam breaker, a vortex breaker, a weir plate, and a mist extractor. These components reduce the risk of carryover (liquid in gas line) and carry under (gas in liquid line) that would affect the flow rate measurement accuracy. 


Applications

Onshore and offshore exploration, development, and production well testing after cleanup

Features

Wide range of vessel sizes for different flow rates

Gas metering with orifice diameters or mass flowmeter

Pneumatic control valves on gas and oil outlets

Fitted with deflector plate, coalescing plates, foam and vortex breaker, weir plate, and mist extractor

Sampling points for all phases

Two relief valves to protect against overpressure

Compliant with ASME VIII, Div. 1 or 2, NACE MR 0175


Surge Tank 

Vertical Surge Tank

Vertical surge tank is an H2S service vessel designed to store liquid hydrocarbons after separation. The surge tank is used to measure liquid flow rates, as well as the combined shrinkage and meter factor. It can also be used as a second stage separator and hold a constant backpressure by using its automatic pressure control valve on the gas outlet.

The surge tank usually consists of a single or double compartment vessel and a level measuring system with sight glasses or magnetic levels. To prevent overpressure and overfilling, the surge tank is fitted with a pressure-relief valve and a high- and lowlevel alarm system.

Surge tanks are designed with a diverter, a vortex breaker, and stiffening rings capable of withstanding a vacuum in the vessel. They are fitted with sampling, pressure, and temperature ports. A bypass manifold is also included.

All surge tanks are shock-protected by a frame, and operate in the vertical position, even they are transported in a horizontal position.


Applications

Onshore and offshore exploration and development oil and gas well testing

Production wells

Compliant with ASME VIII, Div. 1 and NACE MR0175




Gauge Tank 

Atmospheric Gauge Tank

The atmospheric gauge tank, a nonpressurized vessel, is used to measure low flow rates or to calibrate metering devices on the separator oil lines in a testing system. When the flow rate is too low to efficiently drive oil to the burners, the tanks can also be used for temporarily storing the oil.


These skid-mounted units have two compartments.As a transfer pump empties one compartment, the other is being filled. A sight-glass level built into each tank is used to calculate the change in volume based on the physical dimensions of the tank.

Safety features include flame arrestors on each vent from the tank, a grounding strap, and a shearing roof that opens at 3.45 kPa [0.5 psi] burst pressure in the event the vessel is overpressured accidentally. The grounding strap attached to the tank prevents a static charge buildup.

The atmospheric gauge tank is frequently part of the standard equipment for well testing. However, it cannot be used when H2S is present in the effluent because the gas released from the tank is vented into the atmosphere, and that would be hazardous to personnel in the area. 

Applications

Measure low liquid flow rates from a separator.

Calibrate oil meters mounted on the separator oil lines.

Measure a large volume of oil at atmospheric pressure.

Determine the shrinkage factor.

Features

Sight-glass level on each tank compartment

Flame arrestors on each gas vent line

Overpressure shearing roof

Grounding strap

Sampling points and pressure and temperature ports

Codes: ANSI/ASME B31.3


Oil and Gas Manifold

Oil and gas manifold diverts oil or gas, without flow interruption, from the separator to crude oil burner for disposal, to surge tank or gauge tank for measurements or storage, or to a production line. Oil and gas manifold also isolates the test equipment to prevent flow interruption if the testing equipment is pulled out of service temporarily.


The oil manifold typically consists of five ball valves arranged as a manifold and is skid-mounted. The gas manifold is fitted with two ball valves and also mouted on a skid.

Oil and gas manifold valves adopt a proven metal-to-metal, double-sealing design to resist harsh environment operations. All models comply with all applicable standards, such as API Spec. 6D and NACE MR 0175.

Applications

Exploration, development, and production wells using surface well testing equipment


Transfer Pump 

Crude Oil Transfer Pumps

Crude oil transfer pumps are designed to pump oil from a tank to a burner or from a tank into an existing flowline. Normally fitted with an explosion-proof electrical motor for operations in Zone 2 regions.

Gear, screw, and centrifugal pump designs are available. The characteristics of the fluid being pumped and the specific application for the pump determine which pump technology is most suitable.


Applications

?Well testing surge tanks or gauge tank transfer

?Reinjection of separator oil into an existing flowline

?Pump liquids to a tanker Benefits
