Re-completion operations with hydraulic workover units (HWO) have been carried out extensively within the industry, showcasing the high level of efficiency and compact footprint offered by this type of equipment. In an offshore environment, with small jacket platforms, the benefits of the use of said equipment are much more relevant and significant in terms of overall positive impact on the projects. However, re-completions with control lines and sensors, or usually referred to as smart-well re-completions had not been performed with HWO units in the past.

Having stated this premise, the challenge of performing the first smart well re-completion with an HWO unit presented itself with an additional hurdle, which was the fact that the tubing and control lines had to be cut instead of being able to pull from the production packer. This paper showcases the planning, execution, and results of re-completing a well in one of the top offshore gas-producing platforms in the country. Due to a smaller footprint and the advantage to continue the production from neighboring wells simultaneously, the HWO unit was selected as it represented the best overall value for the customer. The job was performed with additional support from a dynamically positioned (DP-2) vessel and a portable crane for efficient rig up and support during the intervention.
