Gas Lift
Gas Lift is system helping lifting oil using high pressure gas. Dhefaf OES provide integrated support equipment for gas lift operation:
Providing gas lift expert for trouble shooting any well problem.
Plunger lift
Plunger lift is an artificial lift method to bring oil from downhole reservoir to surface using reservoir energy.
With specialist calculation method determine the proper design for downhole and surface equipment.
Dhefaf provide wide range of plunger lift equipment, 2 3/8”, 2 7/8”, 3.5, 4.5”. Based on reservoir properties, material will be determined, carbon steel, stainless steel and nicle alloy.
The equipment include plunger, bumper spring, lubricator, motor valve, controller and all supported material.
Wide range of monitoring SCADA system is utilize to ensure the well flow at optimum condition and minimize potential production deferment.
Sucker Rod Pump
Sucker rod pump is most common artificial lift which install for onshore oil well. Dhefaf OES provide integrated support equipment for beam pump operation:
Foam Assisted Lifting
Foam stick
Foam stick utilize for natural flow well, the stick will dissolve with water in the wellbore and generate foam make the pressure reservoir capable to push liquid up to surface and gas enable to flow. Foam stick is drop periodically when the water load up is occur.
Dissolve with loaded water and generate foam in the downhole.
Automatic tool developed to keep automatic drop soap stick to downhole as per design quantity and period to minimize interferent of operator.
Capillary foam injection
Capillary injection foam is a method to unload loaded water in wellbore by inject foam. Specific tool should be installed in the wellhead and downhole. Foam is injected though chemical line continuously along with continues water charging from reservoir.
