Abstract
A sliding sleeve well device has a first sliding sleeve received in a second sliding sleeve.

A metal-to-metal seal is between the sliding sleeves and actuable into sealing contact with the first and second sliding sleeves.
Claims22
A well tool, comprising:
- an outer tubing;
- an inner tubing received in the outer tubing to move axially with respect to the outer tubing;
- a first annular seal between the outer and inner tubings and actuable from a first state to a second, sealed state where the first annular seal sealingly contacts the outer and inner tubings and forms a metal-to-metal seal sealing a fluid path between the outer and inner tubings;
- and
- a second annular seal between and in sealing contact with the outer and inner tubings and sealing the fluid path, the second annular seal comprising a polymer sealing surface.
