The paper aims to describe the design, testing/validation, applications, and field trial results of a 15K Multi-Stage Fracturing (MSF) Intervention-less sleeve system for use in single-point entry or multi-cluster design. Field proven results show efficiencies over plug n perf, coil annular frac and ball drop operations and significant environmental savings. Today, pad design can depend highly on how fracturing operations will be performed. Time between stages, water usage and services required can determine the optimal design of choice when choosing between a single well or multi well pad. Implementing an intervention-less sleeve system reduces the time and water usage between stages and eliminates the need for zipper operations to achieve surface efficiencies. These systems provide completion efficiencies regardless of the number of wells on a pad. By identifying the critical operational limitations of legacy MSF technologies, this paper demonstrates clear benefits between the new intervention-less system and legacy multistage fracturing tools and methods. Performance of current dissolvable solutions is dependent on wellbore conditions and highly variable from one well to the next. Using material science and product design, the time to production is significantly reduced by eliminating the variability experienced when using the current dissolvable products. An operating efficiency and downhole frac performance comparison between the intervention-less system and Plug n Perf applications in single well operations is provided. The elimination of interventions, wireline, pump down, explosives, and drill out prove to provide significant benefits over current completions methods and reduced; cost, time, and environmental impact.
