Downhole multiple bore tubing apparatus

A tubing assembly for entering multiple boreholes comprising:

• a shroud having an axial throughbore;
• a movable tubular member disposed in the axial throughbore;
• and
• a releasable coupling between the shroud and the tubular member;
• wherein the releasable coupling includes a retracted position allowing entry of the tubing assembly into a junction between two boreholes;
• wherein the releasable coupling includes an expanded position allowing movement of the tubular member relative to the shroud and prevents re-entry of the tubing assembly into the junction.

A method for selectively entering multiple boreholes with a tubing string comprising:

• disposing a tubing string in a first bore of a primary well;
• executing a first operation in the first bore using the tubing string;
• removing the tubing string from the first bore and disposing the tubing string in a second bore in a single trip of the tubing string into the primary well;
• and
• executing a second operation in the second bore using the tubing string.
