Operators find the CT annular fracturing technique attractive for a multitude of reasons, including the ability to

  • push and pull during tool conveyance
  • locate and fracture precisely within the formation
  • pinpoint proppant placement where it is most effective
  • monitor real-time fracturing zone pressure to obtain the information needed to control fracture growth and avoid screenouts
  • make a quick recovery from screenouts by circulating the fracturing zone, enabling sand removal
  • reduce the amount of water needed to fracture the well
  • eliminate the need to drill out plugs or remove ball seats.

Overall, CT annular fracturing offers a means to obtain a precise understanding of the fracturing operation downhole and knowledge of how the formation is taking the treatment.
