Transfer pumps are used to transfer crude oil from the test tanks to a pipeline or storage tank or to supply oil to a crude oil burner for disposal.

Transfer pumps may be driven electrically or by diesel or gas engines. Electric drivers are pre- ferred in offshore situations with ample power. Diesel drivers are normally used on land locations when the pump can be placed away from the well test equipment. The pumps are horizontal, end- suction centrifugal pumps with mechanical seals. They supply oil to the burner when there is not

enough pressure for the well effluent to atomize and burn cleanly through the burner. They may also be used to reinject the effluent into the flowlines after flowing through the production test units.

The units can be controlled manu- ally, by using high/low level switches in the stock tanks or by means of a level controller and a system of control valves. Controls always include a pneumatic shut- down to simplify tying into the Emergency Shutdown System. Transfer pumps are ideal for transferring oil or water on location They are designed for corrosive service.

Features and Benefits These transfer pumps

• Can use either a electric, diesel, or gas driver for maximum flexibility

• Is on an oilfield skid

• Uses mechanical pump seals, the most reliable type of seals

Operation

Centrifugal pumps deliver a constant pressure without the pulsations that occur with piston- type pumps. Centrifugal pumps do not over pressure themselves if a downstream valve is accidentally closed. They will automatically bypass the liquid.

Description

Chokes are throttling valves that allow operators to control the wellstream. Chokes are capable of withstanding erosion resulting from the very high velocities occurring at and immediately downstream from the orifice.

The Choke Manifold allows opera- tors to limit erosion to the replace- able parts within the choke. The standard HES choke manifold is a five-valve, component design with a full-bore flow path through the manifold allowing total bypass of the choke control. On one side of the bypass, an adjustable choke allows more flexible control for wellbore cleanup rates. On the other side is a positive choke to give more accurate flow control for predetermined fluids for various test procedures. By using the valving and adjustable choke, the operator can change the positive choke without having to stop operations or affect test objectives. Features and Benefits

The Choke Manifold

• Features dual chokes, one adjust- able and one positive, to help maintain a constant flow rate, which improves test data quality • Is designed for easy maintenance during operations, which saves rig time and overall cost of test

• Offers a lower overall redress cost because of its component design • Allows more options during

cleanup with its bypass through the manifold

• Meets applicable industry stan- dards (API 6A) and can be third- party certified as required Operation

The choke allows the operator control by enabling progressive manual, powered, or fixed control of the wellstream by opening, closing, or selecting an orifice. Chokes help maintain critical flow, even while changing choke size. Critical flow occurs when the

pressure downstream of the choke is one-half or less than the pressure upstream. In this case, the flow rate through the choke depends only on variations of the upstream pressure and on choke setting. Changes in downstream pressure within the critical flow range do not affect the rate of flow through the choke. Noncritical flow occurs when the downstream pressure is more than one-half the upstream pressure. In this case, changing the pressure will affect the flow rate through the choke. The critical flow should always be maintained across the chokes. The choke manifold should be placed as close as possible to the production equipment.
