摘要： A system including a sonic source (110) deployed in a first borehole (116) and a fiber optic distributed sensor (102) deployed in a second borehole (118), both boreholes extending from an earth surface (122) into a formation (120). The optical fiber (102) is configured to react along its length to incident sonic waves (130) generated by the sonic source (110) and propagating through the first borehole(116), through the formation (120), and through the second borehole (118).

摘要： Aspects of the present disclosure are directed to alternative repeater design(s) that advantageously improve signal-to-noise of distributed acoustic sensing (DAS) systems using coherent detection of Rayleigh backscatter in multi-span links including inline amplification that may be employed for example in undersea submarine systems. The repeater designs incorporate Rayleigh combine units (RCU) and Rayleigh drop units (RDU) to reduce Rayleigh backscatter loss as Rayleigh signal(s) is/are routed to a link that propagates the backscatter signal in an opposite direction relative to interrogation pulse(s).

摘要： Systems and methods are provided for generating a model for detection of seismic events. In this regard, one or more processors (220) may receive from one or more stations (110, 120, 130) located along an underwater optical route (100), one or more time series of polarization states (SI, S2, S3) of a detected light signal during a time period. The one or more processors (220) may transform the one or more time series of polarization states (S 1, S2, S3) into one or more spectmms in a frequency domain. Seismic activity data for the time period may be received by the one or more processors (220), where the seismic activity data include one or more seismic events detected in a region at least partially overlapping the underwater optical route (100). The one or more processors then generate a model for detecting seismic events based on the one or more spectmms and the seismic activity data.

摘要： The subject matter of this specification can be embodied in, among other things, a method for removing intermodal distortion that includes receiving a collection of distorted backscattered Rayleigh signals from a collection of modes of an optical fiber, where the collection of distorted backscattered Rayleigh signals are distorted by an intermodal coupling among the collection of modes, receiving a collection of distortion parameters that are descriptive of distortion effects of the intermodal coupling, and determining an undistorted backscattered Rayleigh signal based on the collection of distorted backscattered Rayleigh signals and the collection of distortion parameters.

摘要： A method for characterizing a hydraulic fracture in a subsurface formation includes inducing a pressure change in a borehole drilled through the subsurface formation. At least one of pressure and a time derivative of pressure is measured in the borehole for a selected length of time. At least one physical parameter of at least one fracture is determined using the measured pressure and/or the time derivative of pressure. A method for characterizing hydraulic fracturing rate uses microseismic event count measured through the borehole and its real-time implementation.
