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 21):
An installation for producing fluid such as crude oil and suitable for performing the method according to  claim 1 , the installation comprising at least:\n a ship or floating support on the surface having at least two tanks, and preferably at least three tanks; and an undersea bottom-to-surface connection production pipe comprising a first pipe portion resting on the sea bottom from a well head to the bottom end of a second pipe portion rising to a ship or floating support on the surface; and a first auxiliary pipe for transporting gas extending at least from the ship or floating support on the surface to the bottom end of said second pipe portion; and a second auxiliary pipe extending at least from a first or second tank containing an inert replacement fluid or a first separator gel reagent on board the ship or floating support on the surface to a first static mixer, said second auxiliary pipe being suitable for transferring an inert replacement fluid or a first separator gel reagent into said first mixer; and a third auxiliary pipe extending at least from a third tank containing a second separator gel reagent on board the ship or floating support on the surface to a first static mixer, said third auxiliary pipe being suitable for transferring said second separator gel reagent into said first mixer; and a first separatorgel-forming chamber, preferably formed by a pipe segment situated on the sea bottom at an end to which said first mixer leads, said first chamber leading at its other end to the proximity of the end of the first pipe portion resting on the sea bottom that is closest to the well head.
