Abstract In Malaysia, the service team successfully completed a high demanding fishing job for workover operation. The operation required accessing a well that was suspended due to multiple fish left in the hole Top of Fish (ToF) depth around 50 ft-MDTHF and 3,825 ft-MDTHF depth of cable and coiled tubing (CT) respectively. The challenge was to gain access by recovering armored and flatpack of bird nested CT conveyed Electrical Submersible Pump (ESP) cables around 12,216 ft in length, 2255 ft of parted 2-3/8″ CT, and a 125ft length of ESP assembly. This ESP was conveyed with two different cables inside the coiled tubing to eliminate the need for external control line coupling. During the initial stage of fishing, the 11-3/4″ internal rope spears were modified with various configurations to begin cable recovery. Multiple configurations and customizations of standard fishing tools, such as a 13-3/8″ crankshaft, 9-5/8″ rope spear, 9-5/8″ jack-latch spear, 8-1/8″ overshot, and washover shoes, were made. The experienced technical support fishing team ensured a rapid response, with constant feedback from the rig specialist fishing team, to improve operational efficiency by modifying tools and deploying them to locations on short notice. The proposed solutions were split into three stages: Stage one - to recover all the cables, Stage two - to recover the parted Coil Tubing, and Stage three - to recover the ESP. A various configurations of customized Fishing Bottom Hole Assemblies (BHAs) were planned and fabricated and a total of 63 runs completed during the execution stages to achieve the objective of the fishing operation successfully. The fishing operation was successfully completed as per objectives required. The team recovered 12,216 ft of Flatpack cable and armored cable, using various modified rope spear fishing equipment. Similarly, customized fishing equipment was used to retrieve 2,255 ft of 2-3/8″ CT, followed by the retrieval of 125.1 ft of ESP. Total overall length of fish recovered was 14,596 ft. This operation underscores the expertise of the team in providing innovative and customized fishing solutions for complex wellbore challenges. The team's ability to adapt, modify tools, and respond dynamically ensured the successful completion of this high-risk operation. This paper presents novel contributions to the petroleum industry by offering new insights and methodologies in complex fishing operations. The key additive information includes: Innovative Fishing Techniques – The modification and customization of traditional fishing tools to recover various downhole obstructions efficiently. These adaptive techniques can serve as a reference for future complex well intervention challenges. Multi-Stage Fishing Strategy – This case demonstrates a structured, three-stage approach tailored to specific fish types, providing a replicable framework for similar operations worldwide. Operational Efficiency and Rapid Adaptation – The documented process offers valuable insights into reducing non-productive time (NPT) in wellbore intervention.
