Patent number: 11193364Abstract: 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.Type: GrantFiled: June 3, 2020Date of Patent: December 7, 2021Assignee: Schlumberger Technology CorporationInventors: Joergen K.

Publication number: 20210301642Abstract: 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.Type: ApplicationFiled: March 30, 2020Publication date: September 30, 2021Inventors: Nathaniel Wicks, Joergen Johnsen, Rui Pan
