During the operation the Well Cleaner RCB efficiently removed the cement from the casing walls, plug back total depth (PBTD) was confirmed and the client was assured that the frac bottomhole assembly (BHA) would reach target depth and not have any NPT with an expensive frac crew on location. Since the trial, the operator has continued with the Welltec® solution on a number of additional wells, each with varying amounts of stringers; 0 – 492 ft of cement thus far.
The Well Cleaner RCB with the new Scraper Bit provided a step change for Crescent Point Energy Corp in their removal of cement stringers by offering a one-run solution. With this new capability Welltec offers multiple benefits to operators including reduced cost (~ $10k per well), significantly reduced equipment footprint, less logistics involved in the well preparation and the added value of a CCL log to surface used for both frac operations and future well intervention correlations.
