Downhole water management
MAX. DEPTH12,300 – 12,400 ft
A well in the North Sea producing since 1995 was isolated with tubing that included two Sliding Side Doors (SSD) to control production. Attempts had been made to close both SSDs in 2003, but only the upper SSD had closed. A two-piece straddle assembly was set above the lower SSD, which, however, did not change production. A PLT test showed there was an internal leakage in the tubing. In 2006, the straddle was retrieved and the well temporarily plugged.
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.
