摘要： Various embodiments include apparatus and methods implemented to take into consideration gauge length in optical measurements. In an embodiment, systems and methods are implemented to interrogate an optical fiber disposed in a wellbore, where the optical fiber is subjected to seismic waves, and to generate a seismic wavefield free of gauge length effect and/or to generate a prediction of a seismic wavefield of arbitrary gauge length, based on attenuation factors of a plurality of wavefields acquired from interrogating the optical fiber. In an embodiment, systems and methods are implemented to interrogate an optical fiber disposed in a wellbore, where the optical fiber is subjected to seismic waves, and to convert a seismic wavefield associated with a first gauge length to a seismic wavefield associated with a different gauge length that is a multiple of the first gauge length. Additional apparatus, systems, and methods are disclosed.

摘要： A technique is provided to facilitate monitoring of contaminants which can potentially enter an electric submersible pumping system. A sensor system is used in conjunction with the electric submersible pumping system to detect the presence of specific contaminants which can affect future operation of the electric submersible pumping system. Depending on the embodiment, the sensor system may comprise a sensor or sensors disposed within the electric submersible pumping system and/or in or along components associated with the electric submersible pumping system. Each sensor is used to monitor for the contaminant and to provide data to a control system so as to facilitate decision-making regarding future operation of the electric submersible pumping system.

摘要： A system for estimating a position of a component of a fluid control device includes an optical fiber sensor having a section disposed at a fixed location relative to the fluid control device, the fluid control device configured to be disposed in a borehole in an earth formation and including a moveable member, the fixed location selected so that acoustic signals generated by fluid flowing through the fluid control device are receivable by the section of the optical fiber sensor. The system also includes an interrogation assembly configured to inject an optical signal into the optical fiber and receive a return signal, and a processing device configured to detect the return signal, identify a signal pattern based on the return signal, and estimate a position of the moveable member based on the identified signal pattern.

摘要： The present disclosure relates to systems and methods for treating subterranean formations through adjacent well communications. A method to determine well communication, comprises generating one or more pressure excitation signals via an electrical pump in a first well, wherein the one or more pressure excitation signals produce one or more response signals based on the one or more pressure excitations signals interacting with a subterranean formation; measuring the one or more response signals through transmission of the one or more response signals to a second well with a fiber optic cable, wherein the one or more response signals are measured as time-series data; determining a formation response by processing the one or more response signals with an information handling system; determining a well parameter via one or more sensors; and performing a treatment operation to mitigate well interference between the first well and the second well.

摘要： A method of detecting an event within a wellbore includes obtaining a sample data set, determining a plurality of frequency domain features of the sample data set, comparing the plurality of frequency domain features with an event signature, determining that the plurality of frequency domain features matches the thresholds, ranges, or both of the event signature, and determining the presence of the event within the wellbore based on determining that the plurality of frequency domain features match the thresholds, ranges, or both of the event signature. The sample data set is a sample of an acoustic signal originating within a wellbore including a fluid. The sample data set is representative of the acoustic signal across a frequency spectrum. The event signature includes a plurality of thresholds, ranges, or both corresponding to the plurality of frequency domain features.

摘要： Layered coating applications for sensing telemetry are provided. An example method can include depositing, on a surface of a tool, a waveguide including a first layer of low refractive-index material, a second layer of high refractive-index material applied to a surface of the first layer, and a third layer of low refractive-index material applied to a surface of the second layer; configuring an evanescent wave interaction region on the waveguide, the evanescent wave interaction region including the first layer of low refractive-index material, the second layer of high refractive-index material, and an outer layer of low refractive-index material having a reduced thickness; configuring, at a second location of the waveguide, a non-uniformity configured to reflect light; determining characteristics of the reflected light after traveling through the evanescent wave interaction region; and based on the characteristics of light reflected by the non-uniformity, detecting characteristics of an environment of the tool.

摘要： A system for measuring a porosity of a gravel pack in a wellbore includes a transmitting acoustic transducer attached to a sand screen and configured to transmit an acoustic signal. The system further includes multiple acoustic transducers attached to the sand screen and configured to receive the acoustic signal through the gravel pack. The system also includes a control device configured to receive electrical signals from the multiple acoustic transducers and determine the porosity of the gravel pack around the sand screen based on at least the electrical signals. The electrical signals are generated from the acoustic signal received by the multiple acoustic transducers.

摘要： A deployable device including a deployable member. The deployable member includes an optical fibre. The deployable member is stowed at the device in a first wound configuration and arranged to be deployed from the device to a second unwound configuration within a well. In examples, the deployable device is configured such that, when unwound, the deployable member has a propensity to adhere to a wall within the well. In examples, the deployable member includes at least a first length and second length, the first and second lengths having different mechanical properties.

摘要： A sensor module can be used to make measurements during a single trip into and out of a wellbore in connection with a cement operation. The sensor module can include a detachment mechanism to detachably couple to a cement dart. The sensor module can also include a sensor to make measurements in a run-in-hole configuration prior to detaching from the cement dart and in a come-out-of-hole configuration subsequent to detaching from the cement dart in a wellbore. The sensor module can also include a transceiver to transmit the measurements to a processing device via a communication medium and to receive commands from the processing device via the communication medium.
