Welltec® was called upon due to the operator’s previous experiences with our solution package for mechanical manipulation. The Well Key® design allows it to pass restrictions, as its keys are only extended when positioned accurately in the well to lock into the sliding sleeve profile.
The Well Key profile was positioned with pinpoint accuracy above the sliding sleeve profile and then activated. The Well Tractor® powered up to engage the Well Key profile to the shifting profile. The Well Stroker, configured with 15,000 lbs force, anchored in position on the 5-1/2” 20# blank pipe above the sliding sleeve and powered up to stroke down and shift open the sleeve. It required two strokes to fully open the sliding sleeve door. Once the first sleeve was opened the well was unloaded and the second sleeve opened a few days later.
The operation demonstrated the agility of the Welltec solutions. Even with the upside-down completion, the Well Stroker-Well Key combination brought the well on-line on time and targeted schedule. The well is now producing 10MMsfp/D gas at 18% choke.
This saved the operator from having to pull the upper completion and avoiding the deferred production these alternatives would have cost.
The Well Key brings a high degree of flexibility and reliability to the well completion design as it is designed to shift multiple sliding sleeves in a single run.
The Well Stroker® can push or pull multiple times in the same run irrespective of the depth and deviation. It delivers up to 100,000 lbs of axial force downhole using a bi-directional hydraulic ram.
The Well Tractor® was regarded as a revolution in the industry when it was introduced in the 1990’s. It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells.
