The Y‐tool and Pod system can be combined as a single unit, to provide access to the reservoir through the Y‐Tool bypass tubing, and provide casing isolation from the produced well fluids by having the y‐tool bypass system inside the Pod.

The system eliminates the requirements for an ESP packer and removes the bypass tubing and ESP from being the weak point with high tailpipe loads below the ESP.

This is an advantage for ESP completions stabbing into a lower completion, or ESP drill stem tests (DSTs) where the DST tools are used, and protects the ESP when firing Tubing Conveyed Perforating (TCP) guns.

Access through the bypass tubing allows for production
logging of the well.

Y-Tool Sub Assembly (Comingled Flow)

Advantages

  • Provides production casing isolation as well as access to the reservoir
  • Allows for high loads below the ESP
  • Ideal for ESP Drill Stem Tests that require production logging as part of the programme

Disadvantages

  • Size constraints of ESP and bypass tubing
