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 10):
The method according to  claim 9 , wherein before the steps of restarting production in step e3), before putting the first pipe portion resting on the sea bottom into communication with the second pipe portion rising to the surface and sending the production fluid from the well head, said second pipe portion is emptied by injecting inert gas into the second pipe portion from the top of the second pipe portion and discharging the inert replacement fluid from the second pipe portion to the surface via a first auxiliary gas riser pipe that extends up to the surface from the bottom end of said second pipe portion to which it is connected.
