iProdTech has conducted a review of shut-in wells in an offshore gas field and identified opportunities to re-activate them through decision and risk analysis approach. The study involved ranking of wells in terms of potential reserves, potential costs and potential risks. A methodical approach was utilised to reach to the final matrix of opportunity ranking. The key steps were:
- Review of production history till date including intervention activities and previous attempts of re-activating the wells
- Determination of additional potential through well performance modelling and identifying workover opportunities
- Identification of behind pipe potential from available sub-surface information
- Recommendation of intervention activities including data acquisition programme
- Economic analysis of workover options and ranking
