  • Patent number: 10323174
    Abstract: The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents.

  • Patent number: 10260288
    Abstract: Systems and methods contain fluids discharged from a subsea well or at the surface by capping the well blowout with a pre-positioned capping device. The capping device includes at least one blind shear ram and is separate from a blowout preventer. The blowout preventer may operate to control well events up to a certain pressure, above which the capping device is employed since the capping device has a higher pressure rating than the blowout preventer.

  • Patent number: 10246976
    Abstract: A plunger lift system that uses a linear induction motor instead of gas or fluid pressure to lift the plunger. Electrical voltage is applied to electromagnets installed along the tubing of a wellbore that will induce magnets contained within a special plunger that is introduced inside the tubing to move it and allow it to lift liquids with a piston-like action. The electromotive force may be adjusted by varying the applied voltage as needed to lift the column of liquid from the wellbore or the current reversed to accelerate and optimize plunger descent.

  • Patent number: 10227865
    Abstract: Systems and methods compute dysfunctions via mapping of tri-axial accelerations of drill pipe into drill-string motions. The methods remove gravitational and centripetal accelerations to yield corrected acceleration data due to the vibration only, transform the corrected acceleration data, and maps resulting transformed acceleration data into continuous drill-string positions. The maps provide 2D/3D visualization of drill-string motions to enable real-time optimization and control of well drilling operations and other scenarios where proactive detection of temporal events in automated systems may aid in avoiding failures.
