  • Optimization of CT interventions in extended reach wells

    Drilling wells with longer horizontal sections to maximize the reservoir contact has led to many opportunities for well interventions using Coiled Tubing (CT). In most cases, the complexity has pushed the CT interventions to the limits, driving the development of new solutions to extend CT reach to TD in extended reach wells. The number of these extended wells has grown significantly in recent years in Saudi Arabia, especially in new development fields like the study area discussed in this article, where more than 100 extended reach power water injection wells were placed. For example, the water injection wells in this study area exhibit the typical complexity due to the combination of large-bore tubulars, lower reservoir pressures and long horizontal openhole completions, with lengths between 4,000 and almost 8,000 ft.
