Abstract: Methods, systems, and techniques for controlling the rate of penetration of a drill bit are described. In particular, an operate control loop is evaluated by: determining a travelling block acceleration of a travelling block; determining an acceleration error measurement between the travelling block acceleration and a target travelling block acceleration; determining, based on the acceleration error measurement, a brake control signal; and using the brake control signal to control a braking mechanism configured to apply a variable braking force to the travelling block

Abstract: 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.

Abstract: 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 μm 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.

Abstract: Methods, systems, and techniques for controlling the rate of penetration of a drill bit use drilling parameter measurements read from drilling parameter sensors to evaluate control loops, with the output of one of the control loops at any given time being used by an automatic driller to control the rate of penetration. For each of the drilling parameters, the automatic driller reads a drilling parameter measurement, determines an error measurement that represents a difference between a drilling parameter setpoint and the drilling parameter measurement, and from the error measurement determines an output signal proportional to the rate of penetration of the drill bit. The output signal of one of the control loops is subsequently selected and used to control the rate of penetration.

Abstract: A method for drilling a new oil or gas well in a selected geographical location comprises extracting drilling modes from historic drilling data obtained from a group of drilled wells in the selected geographical location using a pattern recognition model. Each drilling mode represents a distinct pattern that quantifies at least two drilling variables at a specified drilling depth. The method also comprises selecting a sequence of drilling modes at positions along a reference well as reference drilling modes that represent more efficient values for a selection of one or more of the at least two drilling variables compared to other extracted drilling modes; associating drilling parameter settings with the reference drilling modes; and drilling the new oil or gas well applying at least some of the drilling parameter settings.

Abstract: 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. In preferred embodiments, the rotatable filter is tilted with respect to the rotation axis, thereby providing surprisingly improved measurement stability and significantly improved control of the wavelength coverage of the filter spectrometer.

Abstract: Discloses a system for the analysis and measurement of selected gases such as combustible gases contained in a gaseous sample to be analysed including a mixing manifold arrangement to mix the sample gas with a diluting gas to provide a constant gas output flow rate to a detector system. The mixing manifold arrangement automatically reconfigures itself to provide an optimal concentration ratio of sample and diluting mixed gas to the detector system. A constant sample gas input rate is preferred. Excess sample gas not required to maintain a constant mixed sample output rate is discharged.

Abstract: There is described a computer-implemented method of controlling a drilling operation. In particular, there is described a computer-implemented method of determining that a differential pressure is in an oscillating state. In response to determining that the differential pressure is in the oscillating state, a weight on bit setpoint is decreased so as to decrease the differential pressure. There is also described a computer-implemented method of determining a difference between a differential pressure and a target differential pressure. The target differential pressure is less than a differential pressure limit. A weight on bit setpoint is adjusted as a function of the difference between the differential pressure and the target differential pressure so as to adjust the differential pressure and thereby reduce the difference between the differential pressure and the target differential pressure.
