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 16):
The method according to  claim 15 , wherein in order to form the separator gel in step c), the following steps are performed:\n c1 sending, preferably from the ship or floating support on the surface, a first reagent liquid compound in a said second auxiliary pipe and then a second branch connection pipe extending to a second static mixer situated at the sea bottom and leading to said second chamber; and c2) ending, preferably from the ship or floating support on the surface, a second reagent liquid compound in a third auxiliary pipe and then a third branch connection pipe extending to said second static mixer situated on the sea bottom and leading to said second chamber; and c3) mixing the two reagents within said second static mixer and allowing the separator gel to form by reaction between the mixture of two reagents within said second chamber.
