Increasing production offshore
TRAVELED DISTANCE1,100 m (1,200 m - 2,247 m)
1. Due to previous experience, there was concern that sand had entered the well. A drift run with the Well Cleaner® established that this was not the case.
2. Setting a NPR plug at 85° run on the Well Tractor and isolating the lower water producing zone.
3. Opening the 3.688” sliding side door by means of the Well Tractor, Well Stroker and Well Key.
The operation was a rigless intervention carried out from a platform. All three runs were performed in 25 hours and 45 minutes in total.
A key feature of Welltec’s equipment is the fail-safe function that prevents it from getting stuck in the wellbore. When the Well Tractor is powered down, the arms and wheels retract automatically, providing a flush outside diameter surface. The Well Stroker features the same passive fail-safe design as the Well Tractor; the anchors will collapse automatically when it is powered down or disconnected. As for the Well Key, the keys retract into the tool body when all valves have been shifted, allowing the tool string to be pulled out of the hole.
Using the Well Tractor significantly reduces environmental risks. Due to the light design, the Well Tractor reduces fuel consumption and greenhouse gas emissions associated with transporting
heavy equipment into environmentally sensitive areas.
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.
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 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.
