Abstract: The present disclosure is directed to systems and methods for estimating rotational velocity and/or torque of a drill bit during certain drilling operations using torque and rotational velocity measured at a top drive system of the drilling operations. In certain embodiments, a drilling control system may estimate the rotational velocity and/or the torque of the drill bit using torque and rotational velocity detected at the top drive system, in conjunction with the governing equations of the drill string, the top drive, and the bottom hole assembly (including the drill bit itself), which may be transferred into the Laplace domain. In other embodiments, the drilling control system may estimate the rotational velocity and/or the torque of the drill bit using the torque and rotational velocity detected at the top drive system, in conjunction with a finite dimensional model approximation of the drill string based on an assumed mode shape of the drill string or a finite element model of the drill string.

Abstract: A method of rotating a drill string driven by a drive system using a control system implemented by a controller or a filter includes generating a mathematical energy model of the drive system, the drill string, and the controller, wherein the mathematical energy model comprises at least one or more first energy values of the drive system and one or more second energy values of the drill string, determining the one or more first energy values of the drive system and the one or more second energy values of the drill string, measuring one or more vibration values torsional vibrations at the drive system with a sensor, determining an updated proportional gain and an updated integral gain of the controller or the filter based on at least the one or more first energy values of the drive system, the one or more second energy values of the drill string, and the one or more vibration values, providing an output signal representing the updated proportional gain and the updated integral gain to the controller or the fil

Abstract: A method of calibrating individual exit lines of an agricultural ammonia applicator having a delivery path that extends through a manifold and multiple exit lines includes installing a fixed flow restricting orifice upstream of a variable flow restricting orifice and measuring the pressure upstream of the fixed flow restricting orifice. Beginning with the variable flow restricting orifice in an unrestricting flow condition, the pressure downstream of the variable flow restricting orifice is repeatedly measured and compared with the measured upstream pressure. The variable flow restricting orifice is incrementally closed after each comparison so long as the measured pressure downstream of the variable flow restricting orifice and the pressure upstream of the fixed flow restricting orifice remain substantially the same.

Abstract: An ammonia applicator system includes has adjustable orifices with openings having variable sizes that can be changed remotely, without having to disassemble exit lines from a distribution manifold. In this way, the restriction of the exit lines and, thus, line flow rate can be adjusted remotely and/or automatically, even during ammonia application use. Each adjustable orifice may include a valve and an actuator that controls the valve for changing the size of the opening of the adjustable orifice. The actuator may be a rotary actuator, such as a stepper motor, and the valve may include an adjustment knob and a screw that can rotate to allow a needle to advance or regress through an opening of a valve body of the valve.
