RLWI crown plug pulling with Well Stroker®

On a recent RLWI operation in the Gulf of Mexico, the Well Stroker was put into action when the upper crown plug failed to release despite hundreds of jarring attempts on slickline. Over the course of two days, several slickline runs were performed. On the first slickline attempt, 148 jarring attempts failed to free the plug. On the second run another 199 jar impacts yielded the same result. It was believed that these attempts may have broken the seal, which would then have resulted in saltwater inflow creating hydrates. 25% Methanol Ethanol Glycol (MEG) was pumped while jarring, but when no progress was made Welltec® was called upon to assist.
In just 14 strokes, the Well Stroker accomplished what 347 slickline pulling attempts couldn’t; freeing the upper crown plug.
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.
Welltec Release Device® (WRD®) is a simple tool which adds versatility and risk reduction to the operation. It provides predetermined locations in the toolstring where it can be parted, should it become stuck.
