Patent number: 11802473Abstract: Methods, systems, and computer-readable media for controlling a toolface of a downhole tool are described. The toolface of the downhole tool, and a toolface setpoint, are determined. Based on the toolface and the toolface setpoint, a toolface error is determined. Based on the toolface error, one or more drilling parameter setpoints are selected from among multiple drilling parameter setpoints. The selected one or more drilling parameter setpoints are adjusted. The adjusted one or more drilling parameter setpoints are inputted to one or more drilling controllers for controlling the toolface of the downhole tool.Type: GrantFiled: July 27, 2022Date of Patent: October 31, 2023Assignee: Pason Systems Corp.Inventors: Adam Chase Neufeldt, Brian James Eley, Thomas William Charles Wilson, Trevor Leigh Holt

Patent number: 10876390Abstract: There is described a method of controlling a drilling operation. A pipe joint is determined to be entering a rotating control device (RCD). In response to determining that the pipe joint is entering the RCD, a weight-on-bit (WOB) setpoint is increased so as to increase a measured WOB. After increasing the WOB setpoint, the pipe joint is determined to be exiting the RCD. In response to determining that the pipe joint is exiting the RCD, the WOB setpoint is decreased so as to decrease the measured WOB.Type: GrantFiled: May 6, 2020Date of Patent: December 29, 2020Assignee: Pason Systems Corp.Inventors: Sean William Scotvold, Choon-Sun James Ng, Quinn Harrison Hepburn, John Aaron Eddy

Patent number: 10053971Abstract: A method for detecting stick-slip in a drillstring includes (a) measuring a parameter that is a function of a torque applied to the drillstring by a top drive system over a selected time period, the measuring being performed by at least one surface sensor that produces measurement data including torque values over a frequency range; (b) filtering out measurement data that has a frequency outside a selected frequency band, the selected frequency band including a resonant frequency of the drillstring; (c) identifying a minimum and a maximum torque value in the filtered measurement data and determining a difference of these two values; (d) determining a surface stick-slip index by dividing the difference of the maximum and minimum torque values by an average torque value over the selected time period; and (e) displaying the surface stick-slip index on a display.Type: GrantFiled: September 14, 2015Date of Patent: August 21, 2018Assignee: Pason Systems Corp.Inventors: Stephen William Lai, Christopher Darren Salvador, Kenneth Charles Horovatin, Timothy Keith Walter

Patent number: 9958380Abstract: The disclosure relates to spectroscopic systems and spectrometers configured for hydrocarbon gas composition monitoring which provides compound speciation capability and function. In certain embodiments, the system identifies two or more bands of spectral data—e.g., including a band in each of (i) the near infrared and (ii) mid infrared wavelength regions, though bands covering subsets from about 800 nm to about 12 ?m can be used—from the signal corresponding to the hydrocarbon fluid in the gas flow cell, where the two or more bands are not contiguous (e.g., there is at least a 50 nm separation between the nearest ends of two bands). A combined spectrum is then formed from the two or more non-contiguous bands of spectral data and processed to identify and/or quantify the constituents of the hydrocarbon fluid.Type: GrantFiled: June 29, 2015Date of Patent: May 1, 2018Assignees: MKS Instruments, Inc., Pason Systems Corp.Inventor: Vidi Saptari

Patent number: 9739708Abstract: Described herein is a spectroscopic system and method for measuring and monitoring the chemical composition and/or impurity content of a sample or sample stream using absorption light spectroscopy. Specifically, in certain embodiments, this invention relates to the use of sample pressure variation to alter the magnitude of the absorption spectrum (e.g., wavelength-dependent signal) received for the sample, thereby obviating the need for a reference or ‘zero’ sample. Rather than use a reference or ‘zero’ sample, embodiments described herein obtain a spectrum/signal from a sample-containing cell at both a first pressure and a second (different) pressure.Type: GrantFiled: October 11, 2016Date of Patent: August 22, 2017Assignees: MKS Instruments, Inc., Pason Systems Corp.Inventor: Vidi A.

Patent number: 9250132Abstract: The invention relates to methods and systems for measuring and/or monitoring the chemical composition of a sample (e.g., a process stream), and/or detecting specific substances or compounds in a sample, using light spectroscopy such as absorption, emission and fluorescence spectroscopy. In certain embodiments, the invention relates to spectrometers with rotating narrow-band interference optical filter(s) to measure light intensity as a function of wavelength. More specifically, in certain embodiments, the invention relates to a spectrometer system with a rotatable filter assembly with a position detector rigidly attached thereto, and, in certain embodiments, the further use of various oversampling methods and techniques described herein, made particularly useful in conjunction with the rotatable filter assembly.Type: GrantFiled: July 1, 2013Date of Patent: February 2, 2016Assignee: Pason Systems Corp.Inventors: David Bonyuet, Vidi A.

Patent number: 9062524Abstract: Described herein are a method, apparatus and computer readable medium for correcting data points acquired during well drilling. The data points are typically stored in a text file that is accessible by a processor. The processor applies one or more tags to the data points, with each of the tags corresponding to a characteristic of the data points. The processor then identifies one or more data faults in the data points using the one or more tags. Each data fault is indicative of inaccurate data in the data points; i.e., data that does not accurately represent the well as drilled. Following identification of the one or more data faults, the processor corrects one or more of the data faults. The resulting corrected, or cleaned, data is more indicative of the well as actually drilled than the uncorrected data. The processor can be connected to a computer readable medium that stores the statements and instructions that the processor executes.Type: GrantFiled: January 27, 2011Date of Patent: June 23, 2015Assignee: Pason Systems Corp.Inventors: Mariano Calvo, Steven Sheldon, Craig Bye

Patent number: 8896839Abstract: The invention provides spectroscopic systems and spectrometers employing an optical interference filter module having a plurality of bandpass regions. In certain embodiments, the systems include a mechanism for wavelength tuning/scanning and wavelength band decoding based on an angular motion of one or more filters. A spectral processing algorithm separates the multiplexed wavelength-scanned bandpass regions and quantifies the concentrations of the analyzed chemical and/or biological species. The spectroscopic system allows for compact, multi-compound analysis, employing a single-element detector for maximum performance-to-cost ratio. The spectroscopic system also allows for high-sensitivity measurement and robust interference compensation.Type: GrantFiled: April 7, 2010Date of Patent: November 25, 2014Assignee: Pason Systems Corp.Inventor: Vidi A.
