摘要： Systems and methods include a number of optical pulses are transmitted by transmitting, by a distributed acoustic sensor (DAS), where the optical pulses are transmitted at an input port associated with a multimode fibers (MMF) used by the DAS, and where the fundamental mode of the MMF is excited. A number of backscattered Rayleigh signals are collected by the DAS. The Rayleigh signals are recorded as an output intensity profile. A position along the MMF that is subject to vibrations and corresponding vibration parameters are determined by analyzing the recorded output intensity profile.

摘要： Methods of acoustically and optically probing an elongate region and hydrocarbon conveyance systems that utilize the methods. The methods include actively initiating an acoustic signal within an acoustic waveguide that extends along an elongate region. The methods also include optically detecting propagation of the acoustic signal along a length of the acoustic waveguide with a distributed acoustic sensor. The distributed acoustic sensor includes an optical fiber that extends along the length of the acoustic waveguide and defines a plurality of distributed sensing locations. The hydrocarbon conveyance systems include a tube that defines a tubular conduit configured to convey a hydrocarbon, a distributed acoustic sensor, an acoustic waveguide, and a controller. The tube, the distributed acoustic sensor, and the acoustic waveguide extend within an elongate region. The controller is programmed to perform the methods.

摘要： A method of optimizing production of a hydrocarbon-containing reservoir by measuring low-frequency Distributed Acoustic Sensing (LFDAS) data in said well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow and simultaneously measuring Distributed Temperature Sensing (DTS) data from said well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow. An initial model of reservoir flow is provided using the LFDAS and DTS data; the LFDAS and DTS data inverted using Markov chain Monte Carlo method to provide an optimized reservoir model, and that optimized profile utilized to manage hydrocarbon production from said well and other asset wells.

摘要： One embodiment includes receiving distributed acoustic sensing (DAS) data for responses associated with seismic excitations in an area of interest. The area of interest includes a sea surface, the water column, a seafloor, and a subseafloor. The seismic excitations are generated by at least one seismic source in the area of interest. The responses are detected by at least one fiber optic sensing apparatus configured for DAS that is in the 0 water column, on the seafloor, in a wellbore drilled through the seafloor and into the subseafloor, or any combination thereof. The embodiment includes determining a function of speed of sound in water using the DAS data, and correcting a digital seismic image associated with the area of interest using the function of speed of sound in water to generate a corrected digital seismic image.

摘要： A method of evaluating subsea geodetic data, the method includes providing at least one tiltmeter station along a subsea surface. The tiltmeter stations are positioned at a plurality of surface locations. Subsea geodetic data is obtained, the subsea geodetic data including subsea surface gradient information from the tiltmeter stations, and subsea surface elevation information. A set of constraining relationships is generated based on the geodetic data. Values for temporal changes in subsea surface elevations and subsea surface gradients at each desired surface location is identified based on determining a solution to the set of constraining relationships.

摘要： The present disclosure provides optical link management in a marine seismic environment. A first device can transmit, to a second device, a first optical transmission at a first output level. The first optical transmission can include a first packet corresponding to a network protocol. The first device can determine that the second device failed to receive the first packet via the first optical transmission. The first device can transmit, responsive to failure of the first optical transmission, a second optical transmission at a second output level different than the first output level. The second optical transmission can include a second packet corresponding to the network protocol. The first device can identify that the second packet was successfully received by the second link manager agent. The first device can establish, responsive to the identification that the second packet was successfully received, the second output level as a transmission output level for the first device.
