Summary:A method and device for monitoring oil field operations with a fiber optic distributed acoustic sensor (DAS) that uses a continuous wave laser light source and modulates the continuous wave output of the laser light source with pseudo-random binary sequence codes. L'invention concerne un procédé et un dispositif de surveillance d'opérations d'exploitation pétrolière avec un capteur acoustique réparti (DAS) à fibres optiques qui utilise une source de lumière laser continu et module la sortie continue de la source de lumière laser avec des codes à séquence binaire pseudo-aléatoire.
