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 7):
The method according to  claim 1 , wherein after stopping production, first depressurization of the entire bottom-to-top connection production undersea pipe is performed allowing a portion only of the gas contained in the production fluid contained in said production pipe to be discharged on the surface via its top end, the method being characterized in that the following subsequent steps are then performed:\n a) isolating said first production pipe portion from said second pipe portion, and leaving the production fluid in said first production pipe portion, but not in said second pipe portion, which is emptied; and b) additionally depressurizing the first production pipe portion filled with production fluid by reducing the pressure in said first pipe portion and by discharging more completely the gas contained in the production fluid that it contains.
