Well Stroker

Most times Crown plugs are retrieved using Slick Line

Most common reason for not being able to pull the Crown

plug is debris / fill on top of the plug.

The Crown plug typically has a GS profile.

Well Stroker General Description

The Well Stroker is capable of applying Axial force

downhole by the use of a bi-directional hydraulic ram. The

Stroker can be fitted with various shifting or pulling tools

for Mechanical services solutions.

General Description

Electro Hydraulic operational setting tool for plugs, packers and straddlesystems

The tool requires no form of explosives or pre-charge of pressure and isnot dependent on well pressure for operation

The WST can be used to set any plug run on Baker #20 E4 setting tool

Technical Description Make up length: 4,2 m

Maximum OD: 3 7/8

Maximum stroke length: 14

Maximum stroke force: 55.000 lbf

Maximum operational temp: 135C

Maximum well pressure: 10.000 psi

Setting sleeve connection: Running tool/plug connection:

- *The stroke force can be doubled to 110.000 lbf by adding one piston stage tothe tool

- The increased tool length will be 60 cm

Welltec Cutter, none explosive

The Welltec Cutter is a tool that enables efficient, safe drill pipe and casing recovery operationswithout the need for explosives. It is self-centralizing and removes pipe incrementally so that no

shavings are generated and a smooth, polished surface remains after the cut.

The Welltec Cutter eliminates the need for explosives required by most of the industryalternatives. Explosives can pose an operational risk, especially when simultaneous operationsare being conducted. Transfer of explosives may also cause additional logistical requirementsand significant operational delays.

Well Stroker

Well Stroker General Description

The Well Stroker is capable of applying Axial force

downhole by the use of a bi-directional hydraulic ram. The

Stroker can be fitted with a Blind Box deployed dowbhole to

tag cement. When cement top is tagged the stroker can be

anchored and a downward force of ~10 Tons can be applied

to the top of the cement plug
