Anti Blow-Up Tool

Description

The Anti Blow-Up Tool is a wireline service tool designed to be used as a part of the toolstringwhen downhole instruments are to be deployed into a multi zone completion well. It will helpto prevent a toolstring being blown up the production toolstring if the flow rates between zonesshould try to push the toolstring upwards. It has been designed so that if the lower part of thetoolstring starts to lift, two arms are thrown outward to lock into the tubing wall, stoppingany further upward movement. To release the arms, once engaged, you simply pick up on thewireline which lifts the upper body of the tool and closes the arms, releasing the toolstring.

Specifications

Bow Spring Centralizer

Description

The bow spring centralizer is designed to centralize the tool string in large diameter tubing andcasings. The bow spring centralizer is able to pass through the restricted bores of the tail pipeand expand into the casing liner below thus enabling the tools to be held away from the casing.

Specifications

Wireline Roller Centralizer

Description

The wireline roller centralizer is used to connect with toolstring for centralizing in deviatedwells. The design offers a 360 degree wheel contract, reducing the friction caused by contactwith the tubing wall.

Specifications

Fluted Centralizer

Description

Fluted Centralizers are used in deviated wells to ensure that toolstring is at centralized position.

Specifications

Tubing Swage

Description

The Tubing Swage is used to swage out mashed areas and other obstructions in the tubing stringto ensure free passage of subsurface devices. It is sometimes used to open “orange peel” typebull plugs on the lower end of the tubing.

Specifications

Wireline Brush

Description

The wireline brush is used to brush out scale, waxes or packing debris from the tubing stringand tubing nipples prior to running the subsurface devices.

Specifications

Tubing Gauge Cutter

Description

The Tubing Gauge Cutter is used to gauge the tubing and to remove scale, paraffin wax, debrisetc. The dimension of tubing gauge should close to the tubing inside diameter which will ensurethat downhole tools could pass through tubing and nipple without obstruction during wirelineoperations.

Specifications

Tubing Broach

Description

The Tubing Broach is manufactured as a one size /one piece construction with hardened,tapered cutting edges. It can remove burrs in the tubing left after perforating procedures havebeen carried out. One way cut and two way cut broach are available on request.

Specifications

Sand Pump Bailer

Description

The Sand Bailer is used to clear debris which has settled on top of the subsurface equipmentpreventing recovery of the equipment by regular wireline operations.It is a pump type toolwhich operates on the conventional lift pump and piston principle. The Sand Bailer are availablein three designs with flat bottom、angled bottom or flapper bottom.

Specifications

Sample/Drive Down Bailer

Description

The Sample/Drive Down Bailer is a wireline service tool used to take debris samples from thesite of obstruction in the tubing or casing. The Sample/Drive Down Bailer are available in twobasic designs with ball or flapper shoe.

Specifications

Hydrostatic Bailer

Description

The Hydrostatic Bailer is used to clear debris which has settled on top of the subsurfaceequipment preventing recovery of the equipment by regular wireline operations. It is specificallydesigned for use when the debris cannot be removed from the well with Sand Pump Bailer.

Specifications

Single Arm Tubing End Locator

Description

The Tubing End Locator is used to locate the lower end of the tubing so that its depth may bemeasured accurately. The tool string and tubing end locator are lowered down the well, untiljust past the tubing bottom. The finger will now rotate out from a compressed position to ahorizontal position resting on the shear pin. Raising the tool string until a weight increaseappears on the weight indicator, indicates the tubing bottom depth. The tool can re-enter thetubing when the shear pin is cut.

Specifications

Two Arm Repeatable Tubing End Locator

Description

The Tubing End Locator is used to locate the lower end of the tubing so that its depth may bemeasured accurately. The principle advantage of this tool is that it can be used to correlate depthrepeatedly without the need to come out of the wellbore to redress the tool.
