To avoid bringing in a rig, the client began exploring chemical and mechanical interventions for scale removal. Welltec’s e-line solution, the Well Miller was ultimately chosen as the way forward for removing the scale.
The total operation consisted of two successful runs. During the first run, the Well Tractor® and Well Miller were run with a 3.82” OD bit. Hard scale was encountered throughout the milling, but it was successfully removed. On the second run, the Well Tractor and Well Miller were equipped with a rotating scale brush to clean the top of the TRSV.
The well was now cleaned of scale down to the desired depth and the client was able to successfully set the plug and perform the desired well maintenance, thus returning the well to full production.
Welltec’s fast mobilization, combined with the benefits of the e-line interventions exceeded the client’s expectations, returning the well to production earlier than anticipated. The capabilities of Welltec’s Milling Solutions helped the client avoid the time and costs of bringing in a rig. Finally, in light of the NORM encountered in this well, all safety protocols were followed with no incidents.
The Well Miller for Scale Removal transforms the power of the Well Miller into a clean-out application for those scale deposits which can’t be removed effectively with standard clean-out tools.
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.
