Steam diversion assembly

A steam diversion assembly for operations in a wellbore, comprising:

• a housing having an opening through the housing and having a central bore for directing steam through the housing;
• a first sleeve movable within the housing from a valve closed position covering the opening to a valve open position exposing the opening to the central bore of the steam diversion assembly to allow steam to flow outside of the steam diversion assembly;
• an expandable seat movable to shift the first sleeve from the valve closed position to the valve open position, the expandable seat expandable from a first seat configuration having a first inner diameter selected to seat an activation device, to a second seat configuration with a second inner diameter selected to allow the activation device to pass the expandable seat;
• and
• an inner sleeve movable, relative to the first sleeve, by the expandable seat, from a first inner sleeve position when the expandable seat is retained in a seat retaining area, to a second inner sleeve position when the expandable seat is expanded in an expansion area created when the inner sleeve moves from the first inner sleeve position to the second inner sleeve position.
