Since the plug was set in the tubing, everything below the plug needed to stay in place. Without the bridge plug in its proper place, the tubing potentially could be pulled out of the PBR, leaving no barrier to the formation. Thus, the 7” tubing needed to be cut. The rig would not be able to provide tension or confirm the cut through pulling, so the operator wanted multiple methods to confirm the cut before pulling the tubing.
Welltec® had recently completed a cutting job on another well, and the Well Cutter was still in town. On a late Sunday evening, the client called Welltec for the Well Cutter to cut the 7” tubing. Welltec quickly mobilized its tools to the rig. The equipment was picked up and arrived at the docks in under five hours.
After pulling the tools out of hole, Welltec confirmed the cut by inspecting the mechanical indicator on the Well Cutter. The indicator confirmed the SRO data, that the Well Cutter had cut beyond the OD of the tubing.
Additionally, with the bridge plug set in the completion, the cut’s location and effectiveness were essential. If the tubing was pulled with an incomplete cut or cut at the wrong location, the formation could be exposed, a health and safety risk, as well as a costly mistake. Welltec’s solution provided the client with greater peace of mind by providing SRO data as well as a mechanical indicator to confirm the cut.
With confidence in the tools and data, the client was able to pull the tubing successfully after the cut and complete the abandonment operations.
Efficient, safe drill pipe, liner, tubing and casing recovery operations without the need for explosives. The Well Cutter uses a rotating head to remove pipe incrementally, which prevents the creation of shavings.
