摘要： An apparatus for estimating a first property in a borehole penetrating the earth is described. The apparatus includes a carrier configured to be conveyed through the borehole. The apparatus also includes a first sensor disposed at the carrier and configured to perform a first measurement of the first property, the first sensor having a first direction of sensitivity; a second sensor disposed at the carrier and configured to perform a second measurement of a second property, the second sensor having a second direction of sensitivity; and a processor configured to receive the first and second measurements and to correct the first measurement using the second measurement in order to estimate the first property.

摘要： An embodiment of a method of performing aspects of a downhole operation includes receiving a measurement value from a first sensor configured to measure a parameter related to the downhole operation, receiving measurement data from a different sensor, the measurement data related to the downhole operation, and performing, by a sensor evaluation module, an evaluation of the first sensor. The evaluation includes determining a condition of the first sensor based on the measurement data from the different sensor, selecting a rule that prescribes a set of one or more measurement values of the parameter that are plausible if the condition is met, and determining whether the measurement value from the first sensor is plausible based on comparing the measurement value to the prescribed set of one or more measurement values.

摘要： A wired pipe segment includes a body extending from a box end to a pin end and a coupler located in one of the box and pin ends, the coupler including a communication element and a coupler connector in electrical communication therewith and extending away from the communication element. The segment also includes a transmission line extending away from the coupler towards the other of the box and pin end, the transmission line including an inner conductor surrounded by a dielectric material, the inner conductor extending beyond an end of the dielectric material. The segment also includes a connector that electrically connects the coupler to the transmission line, the connector including an inner conductive connection having first and second ends that are, respectively, in contact with the inner conductor and the coupler connector.

摘要： In one aspect, a method for assessing quality of a downhole data is provided. The method, according to one embodiment, may include defining a quality criterion based on one or more parameters of interest, determining a quality assessment value for a first data, determining a quality assessment value for each run of a plurality of runs using the quality criterion, determining a quality factor from the computed quality assessment values of the plurality of runs, and determining a quality level of the first data using the quality assessment value of the first data and the quality factor of the computed quality assessment values.

摘要： An embodiment of a system for estimating a parameter of an earth formation includes at least one formation parameter sensor disposed at a first downhole component and configured to measure a parameter of an earth formation to generate formation parameter data, and one or more processors in operable communication with the at least one formation parameter sensor. The one or more processors are configured to perform: generating a mechanics model of at least one of the first downhole component and a second downhole component, the mechanics model based on geometrical data representing at least one of the first downhole component and the second downhole component; estimating a misalignment of the at least one formation parameter sensor by using the mechanics model; and correcting the formation parameter data based on the misalignment.
