  • Patent number: 11193364
    Abstract: First time-based data, indicative of a first parameter, varies in value with respect to time and is associated with a drilling operation utilized to construct a well extending into a subterranean formation. A moving window transform of second time-based data is performed to generate a three-dimensional expression of frequency and amplitude of the first parameter or a second parameter. The second time-based data is based on the first time-based data. The second parameter varies in value with respect to time and is dependent upon the first parameter. The drilling operation is assessed based on the expression.

  • Publication number: 20210354444
    Abstract: In some examples, a circuit for use with a memory element and a nozzle for outputting fluid, includes a data line, a fire line, and a selector responsive to the data line to select the memory element or the nozzle. The selector is to select the memory element responsive to the data line having a first value, and to select the nozzle responsive to the data line having a second value different from the first value. The fire line is to control activation of the nozzle in response to the nozzle being selected by the selector, and to communicate data of the memory element in response to the memory element being selected by the selector.

  • Publication number: 20210301642
    Abstract: Systems and methods for using high rate telemetry to improve drilling operations. A method may include performing drilling operations with a wired drill pipe (WDP) string in an oil and/or gas well. The drilling operations may include pumping drilling fluid to a mud motor of the WDP string through an internal passage of the WDP string and vertically moving the WDP string via a drawworks while controlling the drawworks to change speed of the WDP string based on downhole data received by wellsite surface equipment via electrical conductors integral to WDP of the WDP string. The received downhole data may include downhole pressure data that is generated downhole by a pressure sensor and is indicative of pressure of the drilling fluid in the internal passage.
