    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: A method of analyzing a subterranean formation. The method includes specifying a volume of interest in the subterranean formation, specifying an injector wellsite that penetrates the volume of interest, specifying a first producer wellsite and a second producer wellsite, each of which penetrates the volume of interest, calculating a first Injectivity-Productivity Index (IPI) for a first injector-producer wellsite pair which includes the injector wellsite and the first producer wellsite, calculating a second IPI for a second injector-producer wellsite pair which includes the injector wellsite and the second producer wellsite, determining whether the first IPI is substantially equal to the second IPI to obtain an analysis result, and adjusting a wellsite operation based on the analysis result.
