Stroker services

Manipulating sliding sleeve doors and changing gas lift valves in deviated wells has previously been done by coiled tubing which are expensive and time-consuming operations. With the introduction of the PowerTrac® Advance™ Stroker service Aker Solutions can offer clients an alternative solution which will save both time, money and has a great HSE advantage compared to traditional coiled tubing operations.

Applications and key features

Stroker

  • Can stroke repeatedly in one run
  • Bi-directional
  • Stroke position control with 1mm accuracy
  • Maximum operating tubing ID can be increased with extended anchor pads without increasing the tool OD
  • Electrical feed-through
  • Possible to log while operating
  • Fail-safe release mechanism

Hydraulic Shifting Tool (HST)

  • Applicable to all known smart well sleeves and sliding sleeve door profiles
  • Bi-directional
  • Multiple manipulation of sleeves in one run
  • To be used in combination with PowerTrac® Stroker
  • Fail-safe release mechanism

Modified Kick-Over Tool (KOT)

  • Can be operated in highly deviated and horizontal wells
  • Setting and retrieval of Gas Lift Valves (GLV) and Chemical Injection Valves (CIV)
  • Improved design ensures accurate setting / retrieving sequences without damaging the seals
  • Can be used in combination with PowerTrac® Stroker

The PowerTrac® Advance (PTA) Stroker is a powerful tool that can perform numerous operations downhole, different types are available and can be configured according to operational targets.

The PTA® Stroker can be deployed on standard mono-conductor cables and is fully compatible with the PowerTrac® Advance Tractors. The PTA® Stroker is surface-controlled via a laptop and a single power source, requiring little preparation and rig-up time.

All strokers are equipped with position control, enabling the operator to monitor and control the stroking action ensuring optimal setting / pulling operations. In addition, the strokers are available with electrical feed-through which makes it possible to perform logging and other e-line operations below the stroker.

In addition to setting and retrieval of plugs the PTA® Stroker can be used in conjuction with other tools expanding the range of service applications:

With the Hydraulic Shifting Tool (HST) it is possible to shift sliding sleeve doors (SSD) in both directions - repeatedly - in one run. This will save the client for both time and money as the operation requires less rig-time and runs compared to conventional methods as coiled tubing. 

Aker Solutions' modified Kick Over Tool (KOT) has a patented re-inforced kick-over mechanism making us able to set and retrieve GLVs and CIVs in highly deviated sections of a well. This makes it possible to position GLVs where it is most benefitial from a production point of view and not being restricted by well deviation in order to optimize production.
