Abstract: A vibratory separator (in one aspect, a shale shaker) and methods for using it, the separator in certain aspects having a base, a basket movably mounted on the base, screen apparatus on the basket, material flowing onto the screen apparatus for treatment, at least a portion of the screen apparatus not inclined downhill (e.g. said portion horizontal or uphill), electromagnetic vibratory apparatus connected to the basket for vibrating the basket and the screen apparatus, driving apparatus for driving the electromagnetic vibratory apparatus, and control apparatus (on-site and/or remote) for controlling the driving apparatus and the electromagnetic vibratory apparatus; the material, in one aspect, being drilling fluid material with solids therein.

Abstract: Methods and systems for controlling movement of a bit of a drilling assembly during reaming of an already-drilled hole; the methods, in certain aspects, including determining a ream speed for downward movement of the bit in the hole, moving the bit downward in a hole at said ream speed, determining a time period for deceleration of the bit to the hole bottom, determining a value for a target drilling parameter for drilling beyond the bottom of the hole, decelerating the bit (linearly or non-linearly) for the time period, and achieving the value for the target drilling parameter when the bit reaches the bottom of the hole.

Abstract: A vibratory separator and methods for using it, the separator in certain aspects having a base, a basket on the base, motor apparatus for vibrating the basket and screen apparatus thereon, variable frequency drive apparatus for selectively driving the vibratory motor apparatus, and, in certain aspects, angle adjustment apparatus for adjusting angle of the basket; and, in certain aspects, for sensing a parameter indicative of operation of the vibratory separator, and control apparatus for receiving signals from the sensor apparatus, for controlling the separator based on said signals; and, in certain aspects, for automatically signalling a drive apparatus to change the speed of the motor apparatus; and, in certain aspects, the vibratory motor apparatus connectible to the basket at a plurality of locations so that a motion profile of the basket is selectively variable between linear, elliptical, and circular motion.

Abstract: A choke diagnostic system with a positioner for moving a choke mechanism of a choke, a choke isolation valve for placing the choke in standby mode, and a processor controlling the choke and, in certain aspects, the processor for commanding the positioner to move the choke mechanism while the choke is in standby mode.

Abstract: A controller provides an automatic bit protection sequence for an autodriller that can be initiated during the initial stage of set down of the bit within the formation. The automatic protection sequence establishes a setpoint for a parameter of interest (such as weight on bit, ROP, torque) associated with operation of the drilling system and then initiates a gradual increase in that parameter in order to achieve the setpoint. The bit protection sequence may be adjustable so that varying degrees of gradualness may be selected. The controller of the autodriller may also be provided with measured data for torque, rate of penetration (ROP) and/or the differential pressure of the mud motor of the drilling system. Each of these parameters is provided with a predetermined setpoint, and each may be selected as the controlling parameter for operation of the autodriller.
