Abstract: A system includes an optical fiber and an interrogator to provide source light to the optical fiber. The system also includes a receiver coupled to the optical fiber. The receiver includes at least one fiber optic coupler that receives backscattered light and that produces optical interferometry signals from the backscattered light. The receiver also includes photo-detectors that produce an electrical signal for each of said optical interferometry signals. The system also includes at least one digitizer that digitizes the electrical signals. The system also includes at least one processing unit that calculates I/Q data from the digitized electrical signals, corrects the I/Q data based on ellipse fitting, determines phase values based on the corrected I/Q data, and determines distributed sensing parameter values based on the phase values.

Abstract: Determining a type of annular material in a wellbore comprises measuring an acoustic noise of one or more reference materials and thereby generating a corresponding one or more acoustic profiles, monitoring the annular material with an acoustic sensor positioned in the wellbore and thereby obtaining an acoustic response of the annular material, comparing the acoustic response with the one or more acoustic profiles using a processor communicably coupled to the acoustic sensor, and characterizing the annular material based on the comparison of the acoustic response and the one or more acoustic profiles.

Abstract: An example system for detecting mud pulses may include a distributed acoustic sensing (DAS) data collection system coupled to a downhole drilling system, and an information handling system communicably coupled to the DAS data collection system. The information handling system may include a processor and memory coupled to the processor. The memory may contain a set of instructions that, when executed by the processor, cause the processor to receive quadrature DAS data signals from the DAS data collection system, determine a first template signal associated with mud pulses, transform the determined first template signal into analytic representation form, perform a matched filter operation using the quadrature DAS data signals and the transformed first template signal, and analyze an output signal of the matched filter operation to detect mud pulses in the downhole drilling system.

Abstract: An example omnidirectional sensing system may include a fiber optic cable wrapped around a sphere or spheroid in no preferred direction. The wrapped fiber optic cable may make the system more receptive to acoustic disturbances and increase the fidelity of the sensor in the area of the sphere or spheroid. The system may be used, for instance, for vertical seismic profiling via a wireline technique, placement at the surface of the earth for surface seismic, and in marine applications.

Abstract: Various systems and methods for implementing and using a downhole all-optical magnetometer include downhole all-optical magnetometer sensor, including optical receiving ports that receive light pulses, a depolarizer (506) that depolarizes received light pulses, and a polarizer (508a) that polarizes depolarized light pulses from the depolarizer. The sensor further includes a vapor-filled cell (516) through which polarized light pulses from the polarizer are directed, wherein interactions between vapor and a magnetic field within the vapor-filled cell alter at least some of the polarized light pulses, and an optical transmitting port that directs altered light pulses from the vapor-filled cell out of the sensor.

The energy spectrum information corresponds to energy calculated for each of a limited number of frequency subbands by segmenting the distributed sensing signal into blocks having a predetermined block length and by applying a filter having a filter length that is smaller than the predetermined block length.

Abstract: A method includes attaching a fiber optic cable to a cementing tool configured to attach to a cementing plug displace cement in a hydrocarbon well. The method can also include deploying the cementing tool in the hydrocarbon well to cause the cementing plug to begin releasing cement to form to displace cement to form a cement sheath in the hydrocarbon well. Additionally, the method can also include receiving, by a sensor receiver at a wellhead of the hydrocarbon well, a signal with cementing data as the cement sheath cures. Furthermore, the method can also include determining whether the cement sheath is curing properly. A system and a non-transitory computer readable medium are also provided.
