    摘要： Acoustic monitoring is carried out using a fiber optic cable. Coherent Rayleigh noise generated by the transmission of a coherent beam of radiation through the fiber optic cable is detected, a phase of the coherent Rayleigh noise is measured and the measured phase is processed to identify an acoustic occurrence along the fiber optic cable. In certain aspects an optical fiber serves as a distributed interferometer that may be used to monitor a conduit, wellbore or reservoir. The distributed interferometric monitoring provides for accurate detection of acoustic occurrences along the fiber optic cable and these acoustic occurrences may include fluid flow in a pipeline or wellbore, processes taking place in a wellbore or pipeline, fracturing, gravel packing, or production logging.

    摘要： Injection of gas into a managed pressure drilling system to provide for operation of the drilling system in a pressure window defined by the pore pressure of a formation being drilled and a fracture pressure of the formation. The gas is injected through gas injection ports and drilling fluids are allowed to flow between the drilling annulus and the gas injection system though a plurality of flow ports that are disposed vertically below the gas injection ports in the borehole being drilled. The gas injection ports and the flow ports are configured so that when gas is flowing through the gas injection ports, the flow ports are sealed.
