Abstract: A drilling system includes a rotatable string for connecting with a bit for drilling a borehole, and an active stabilizer which includes a body having an outer surface for contacting a wall of the borehole, and a plurality of actuators connecting the body and the string and capable of driving the string to deviate away from a center of the borehole with a displacement to change a drilling direction. The drilling system further includes a module for measuring direction parameters including at least one of a declination angle and an azimuth angle of the borehole, a module for measuring imbalance parameters including at least one of a lateral force, a bending moment and a torque near the drill bit, and a controller including a calculator for calculating an adjustment needed for the displacement, based on the measured parameters and expected values of these parameters.

Abstract: A surface-based separation assembly for use in separating fluid. The surface-based separation assembly includes a gas-liquid separator configured to receive a fluid stream, and configured to separate the fluid stream into a gas stream and a mixed stream of at least two liquids. A liquid-liquid separator is in flow communication with the gas-liquid separator. The liquid-liquid separator is configured to receive the mixed stream from the gas-liquid separator, and is configured to separate the mixed stream into a first liquid stream and a second liquid stream. The assembly further includes a rotatable shaft including a first portion extending through the gas-liquid separator, and a second portion extending through the liquid-liquid separator. The rotatable shaft is configured to induce actuation of the gas-liquid separator and the liquid-liquid separator.

Abstract: An apparatus for inspecting integrity of a multi-barrier wellbore is described. The apparatus includes at least one source to generate radiation to impinge a target volume of the wellbore. The apparatus includes a source collimator having a plurality of alternating blocking channels and passing channels to direct radiation to impinge the target volume, such that the radiation directed from each passing channel forms a plurality of field of views extending radially into the target volume. The apparatus further includes at least one detector to receive backscatter rays arising from each respective field of view from the plurality of field of views and to generate an image representative of an inspected portion of the wellbore. The apparatus is useful for inspecting very small volumes in the multiple barriers of the wellbore and determine the integrity of the wellbore based on the different densities in the image of the inspected portion.

Abstract: A sensing system that includes a cylindrical body including an internal flow channel that channels a first fluid therethrough, and a sampling chamber. The sampling chamber is in flow communication with an ambient environment. A venturi device is coupled within the cylindrical body, and the venturi device includes a high pressure portion and a low pressure portion. The low pressure portion is in flow communication with the sampling chamber. A valve is coupled within the cylindrical body and is positionable in at least a first position. A first flow channel is defined between the internal flow channel and the high pressure portion through the valve. The first flow channel channels the first fluid towards the high pressure portion such that the low pressure portion draws a second fluid into the sampling chamber from the ambient environment. A sensor assembly determines characteristics of the second fluid within the sampling chamber.

Abstract: A rotary steerable drilling system includes a collar, a drill bit, and a bit shaft connecting the drill bit to the collar. The bit shaft is coupled to the collar through a joint capable of transmitting a torque from the collar to the bit shaft and is swingable with respect to the collar around the joint. The system, further includes first eccentric wheel and second eccentric wheel coupled to the bit shaft and rotatable to swing the bit shaft with respect to the collar around the joint to change a drilling direction, a controller for controlling the first eccentric wheel and second eccentric wheel to harmoniously rotate such that the swing of the bit shaft substantially compensates rotation of the bit shaft, and an active stabilizer mounted on the bit shaft and capable of pushing the bit shaft to deviate to cause a lateral displacement and a tilt angle of the drill bit.
