Abstract:
Method of stopping and restarting production in an undersea bottom-to-surface connection production pipe having a first pipe portion on the sea bottom from a well head to the bottom end of a second pipe portion extending to a ship or floating. When production is stopped, at least the first pipe portion is filled with a depressurized production fluid. Thereafter the following steps are performed: e1) forming a gel from two reagents in a first gel-forming chamber on the sea bottom; e2) sending a quantity of separator gel into the first pipe portion that pushes the cold fluid contained in the first pipe portion to the second pipe portion, prior to closing the first chamber; and then; e3) starting production, the gel forming physical separation and thermal and chemical isolation between firstly the production fluid and secondly a production fluid within the first production pipe portion.

Claim (Index 20):
The method according to  claim 16 , wherein in step d), or after step d), the gel and the liquid in said buffer pipe and then in the second production pipe portion is raised by sending inert gas from the ship or floating support on the surface into said first auxiliary pipe leading to the distal end of the buffer pipe.
