Abstract: A stick-slip vibration mitigation system and a method of using the system are provided. The system includes a sensor, a processor, a non-transitory storage medium, and a controller. The system is operable to be used with a drill-string in a wellbore during a drilling process to mitigate stick-slip vibration of the drill-string.

Abstract: A method of forming a mudline cellar includes positioning a mudline cellar forming member on a seafloor surface. The mudline cellar forming member includes an outer surface and an inner surface that defines an inner cavity. The method further includes driving the mudline cellar forming member into the seafloor surface, and excavating the inner cavity of the mudline forming member to establish the mudline cellar.

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.

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.

Abstract: Methods and systems relate to SAGD injection and/or production wells that utilize flow distribution control devices. Additionally, methods and systems using limited vertical spacing separating the wells are described. These methods and systems improve steam assisted gravity drainage (SAGD) oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.

Abstract: A method of performing notch compensation and a system to perform notch compensation for a first seismic streamer are described. The method includes disposing the first seismic streamer at a first depth, where the seismic streamer includes a first set of sensors to receive reflections resulting from a seismic source, the reflections indicating a notch at a frequency. The method also includes disposing a second seismic streamer at a second depth, the second depth being less than the first depth and the second seismic streamer including a second set of sensors to receive reflections resulting from the seismic source. The method further includes processing the reflections received by the first set of sensors and the second set of sensors together to derive the match filter, and applying the match filter to the reflections received by the first set of sensors of the first seismic streamer to compensate for the notch.

Abstract: Paraffin deposits from downhole tubing, pumps and valves are removed by hot water and recycling the hot water to allow continual intermittent cleaning throughout the lifespan of the well. Heated water travels down the hollow rod annulus, entering the hollow rod string through ports at the bottom, temporarily heating both strings to melt and mobilized paraffin to enable intermittent pumping paraffin and debris to surface.
