The RTTS packer , Retrievable Test-Treat-Squeeze Packer, is a large-bore, retrievable downhole tool designed to create a temporary, pressure-tight seal within a cased wellbore.

One of its major advantages is that it can be set and reset multiple times using only the tubing string, without requiring additional downhole tools or interventions.

The design of the RTTS packer makes it highly suitable for a broad range of well intervention activities, allowing operators to isolate specific zones for testing, treatment, and other forms of well management.
