During the operation, Welltec® provided casing collar locator and gamma ray tools that worked with the wireline provider’s data to correlate depth. Once at depth, cutting commenced and lasted for approximately 20 minutes before the surface readout (SRO) data indicated that the Well Cutter® had cut past the outer diameter (OD) of the tubing.
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.
Welltec® delivered a successful cutting solution quickly, within hours of the client’s call. Initially, the operator was unsure if the tubing would be in tension or compression but knew of the Well Cutter’s capabilities to cut in a variety of environments.
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.
