Abstract Application of Cement packer to facilitate the completion of shallow zones above the existing production packer using rig less methods. This technique is especially cost-effective in offshore operations, as it eliminates the need for rig-based workovers. This paper provides key insights and recommendations, with a focus on zone identification, well intervention strategies, coiled tubing cement design, and perforation techniques specific to cement packer applications. The Operator and its service partners utilized rig less cement packer technique, combined with through-tubing perforation, to complete and monetize shallow producing zones. While this technique has proven highly effective, it also presented multiple technical & operational challenges that required careful planning across all phases of the well program. The operations team conducted a thorough lookback analysis of previous cement packer jobs, reviewing every step of the design and execution process. The paper will present the findings, risk assessments, and recommendations for future operations based on this analysis. This study outlines key challenges in cement packer applications including robust candidate identification, cement slurry design and optimization, perforation techniques, and complexities of managing extended cemented intervals. One of the key highlights is safe and seamless operation of 180bbls batch mixing for a single stage coiled tubing operation to cement a 2,540ft interval whilst maintaining slurry quality and stability. The operation was successfully executed with optimized timing vs planned with proper planning and good preparation prior mixing cement, post execution cement bond log was run proving good cement placement across the interval and the result post execution the well manages to produce with 2kbd instantaneous build up post add perf. Cement packer completions for shallow reservoirs are poised to become one of the cost-effective solutions as the primary production zones are nearing depletion. Despite the long-standing use of this technique, a thorough lookback analysis and risk assessment of its application across multiple wells are limited. This paper breaks new ground, providing valuable insights for operators and solution providers aiming to implement cost-effective solution supported by detailed risk analysis to unlock more marginal opportunities from shallow reservoirs.
