Milling of cast iron bridge plug
TOTAL OPERATIONAL TIME67 hours (rig up to rig down)
ACTUAL MILLING TIME9 hours
UNIQUE OPERATIONAll milled material was recovered
However, the attempt to set the cast iron bridge plug was unsuccessful due to a setting tool failure. The tool string freefell for 50 ft, which caused the bridge plug to be set at 16,200 ft MD - 80 ft too high.
• Avoiding any additional fluid handling associated with CT milling operations
• Personnel and deck space restrictions prevented a CT operation on short notice
• Loss in potential well production was costing +USD 115,000/day
Using Welltec’s technology 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.
Deployed on e-line, our modular milling tools have proven to be robust and highly effective in removing well components that are malfunctioning or no longer required with robotic precision.
