Multiple reservoirs can be produced independently in the same well bore. In cases where the upper zone and the lower zone require an ESP, a dual zone completion can be used with a single production tubing string by comingling the discharge of each ESP.

Compared to the seal bore packer, this configuration has no means of zonal isolation during workover, and requires sufficient distance between zones for the ESP packer and ESP.

Pump Support For Y-Tool Applications

Advantages

  • Increased production by producing two zones independently with dissimilar productivity
  • Allows fiscal measurement of production from each zone
  • Only need to drill one well to maximise production from both zones
  • Pod system eliminates ESP cable going past perforations
  • Seal bore packer used when distance between zones is small
  • Allows zone isolation with an isolation valve during workover to prevent zone communication
