Claim 6:
7. A device for improving operation of a wellbore, said wellbore comprising a drill pipe in which a fluid circulates and an optical fiber positioned outside the drill pipe, said device for improving the operation of a wellbore being coupled to at least one outlet valve or injection valve, wherein the circulation of said fluid is controllable at least in part by said at least one outlet valve or injection valve, said device for improving the operation of a wellbore further comprising:
an optical device configured to generate two digital orthogonal backscatter signals from a light signal injected into said optical fiber, and
a processing device configured to generate, from distributed pressure values and fluid circulation parameters including an optical signal intensity ratio as a function of distance calculated from the two digital orthogonal backscatter signals, opening control data of the outlet valve or of the injection valve to control opening of the outlet valve or the injection valve.
