Objective/Scope: In this paper, the author presents a case story from the Middle East in which multiple tubing cuts were performed using a new, non-explosive, electric line (e-line) conveyed tool on the same run in the hole. As this was an outstanding achievement, never accomplished before in the region, the paper discusses the planning, the operation, the achievements and the lessons learned.
Methods, Procedures, Process: A common practice for workover operations is to remove the existing completion and replace it with a new completion, either the same or sometimes with improved components. One of the steps required to pull the completion in this case is a run to cut the production tubing in one or more places prior to pulling the completion from the wellbore. A common practice is the use of an e-line cutting tool. Conventionally the best practice for this e-line tubing cut operation is to keep the pipe/casing in tension while performing the required cuts. This practice prevents pinching of the cutting blades and ensures higher chance of a successful cut for the operation.
Results, Observations, Conclusions: An operator in the Middle East has experienced success in performing multiple tubing cuts in a single run on an offshore well using an e-line deployed electric over hydraulic cutting tool with tubing in compression.
Novel/Additive Information: Moreover the paper reviews test results from a new style of machining arms and discusses how this technology is enabling an operator to perform rigless cuts to eliminate the
cost of rig time to be more efficient, safe and cost effective.
