of fluid from the well and is the first piece of surface test equipment. It consists of four gate
valves: one master valve, two wing valves (flow line & kill line), and one swab valve. A swivel
below the main block of the test tree allows drill stem to rotate freely, while the test tree remains
stationary.

Surface safety valve (SSV) is a hydraulically actuated fail-safe gate valve for testing oil and gas wells
with high flow rate, high pressure, or the presence of H2S. The SSV is used to quickly shut down the
well choke manifold upstream in the event of overpressure, failure, a leak in downstream equipment,
or any other well emergency requiring an immediate shut down.
applications
During onshore & offshore exploration, development, and
production well testing of HPHT wells or the presence of
H2S
When an additional pressure barrier is needed in addition
to the master valve

Choke Manifold consists of four manual valves (five if a bypass valve is included) and is used to
control the flow rate and reduce well pressure before the flow enters the processing equipment.
The CMF also includes an adjustable choke, a positive choke, and several pressure or sampling
ports to monitor pressure or fluid characteristics. The CMF design allows the well to flow, through
positive chokes for flow rate reference as well as adjustable chokes. Dual flow paths allow fast
choke changes without interrupting the flow.

The purpose of the Chemical Injection Pump is to inject methanol upstream of the choke manifold
to inhibit hydrate freezing as a result of the pressure drop. This increases the reliability and range
for pressure drop through the choke. The methanol is typically injected through the data header’s
chemical injection port which includes one check valve.

Oil Transfer Pumps are designed to pump oil from a tank to a burner or to send oil from a tank to a
pipeline, another tank or a tanker. Oil Transfer pump can be broadly classified as screw pump and
centrifugal pump which are used commonly.

centrifugal pump
Centrifugal pump is suitable for high speed fluid, mainly composed by impeller which produces liquid
velocity and volute which forces the liquid to discharge from the pump. Centrifugal pump operates at
relatively high rotation speeds (e.g. 3,000 rpm), it uses centrifugal force to impart high velocity to the
liquid, and then converts most of this velocity to pressure.
Even, continuous, steady flow
Constant flow rate
Low fluid speed at inlet pipe and pump inlet
High efficiency
www.sunrypetro.com
screw pump
Screw pump is well adapted to handling viscous fluids. The single-screw pump mainly consists of a
stator with dual spiral chambers and a rotor engaged with the stator in the shaft sleeve. When the
rotor turns in the stator chamber, the sealed chamber formed between the rotor and stator will
make axial movement along the spiral line of the rotor, oil will be conveyed evenly, continuously,
and constantly from the suction side to the discharge side.
