  • Patent number: 10316620
    Abstract: A system for selectively actuating sliding valves includes a segmented sleeve exhibiting a rocking (or pivoting) function. The rocking allows the bottom end of the sleeve to open wider when the front of a dart is pressed against it, provided the length of the dart is shorter than a “target length” determined by the sleeve geometry. When the dart is at least as long as the “target length” of the sleeve, the back of the dart prevents the sleeve from rocking as the front of the dart is pressed against the bottom seat. The dart remains pressed against the sleeve, effectively isolating the wellbore section above the dart from the one below it. Multiple zones can thus be independently isolated by using a set of sleeves with similar diameters, but different “target lengths.

  • Patent number: 10309196
    Abstract: A ball seat is integrated with a movable biased sleeve. Sleeve movement against its bias moves a diverter from a position outside the through passage to a position across the main passage such that any balls that drop down will be directed by the diverter into an annular retention volume. In treatment of the formation for fluid loss the movement of a seat with the seated ball opens lateral ports for delivery of sealing material and moves the diverter. Smaller balls are then introduced to close lateral ports above the seated ball so pressure can be built to shift the sleeve and extrude the first ball. Once the seated ball blows through, the smaller balls come through the seat and are all diverted to an annular capture volume. The device is resettable for multiple operations. Fluid flow cessation closes lateral ports and opens a through passage retracting the diverter.

  • Patent number: 10301908
    Abstract: An array of sliding sleeve valves are uniquely addressable without control lines or wires to open for a treatment and then close and then selectively open for production. The discrete movements employ an available pressure source such as tubing pressure and change the piston areas on opposed sides of a sliding sleeve valve to get the desired movements. Access valves to tubing pressure can be actuated in a desired sequence with signals such as acoustic or electromagnetic, for example. Access to one piston area that communicates opposed and offsetting piston areas to the tubing hydrostatic can be achieved with a straddle tool breaking a rupture disc. The piston is then in pressure balanced and can be moved in a desired direction with the straddle tool straddling access locations to the piston from above or below.

  • Patent number: 10174587
    Abstract: Apparatus and methods are described for autonomously controlling fluid flow in a tubular in a wellbore. A fluid is flowed through an inlet passageway into a biasing mechanism. A fluid flow distribution is established across the biasing mechanism. The fluid flow distribution is altered in response to a change in the fluid characteristic over time. In response, fluid flow through a downstream sticky switch assembly is altered, thereby altering fluid flow patterns in a downstream vortex assembly. The method selects based on a fluid characteristic, such as viscosity, density, velocity, flow rate, etc. The biasing mechanism includes a semi-doughnut-shaped wall contour element formed along one side.

  • Patent number: 10107052
    Abstract: An assembly uses a choke to control flow of wellbore fluid in a drilling system. A controller operatively coupled to the choke can control opening/closing of the choke with hydraulic power and an actuator. The control operates the opening/closing of the choke with a choke control value to control a parameter in the drilling system, such as pressure or flow. The control measure a time for the choke to at least reach a position toward a full open/closed position during a full opening/closing operation and calculates a current opening/closing speed of the choke. When this current speed is compared to a previously stored speed, the control adjusts the choke control value for the choke based on any difference.
