Abstract: An energy harvesting rotating control device includes an inner member and a locking member. The inner member is configured to rotate about a longitudinal axis. The locking member is configured to move toward the longitudinal axis of the inner member and engage a shoulder of the inner member. An actuator is configured to move the locking member when actuated by an electrical power source. The locking member engaging the shoulder of the inner member limits the movement of the inner member.

Abstract: A shaker separates components of a slurry. The shaker has a screen with a pressure differential applied to the screen to remove a portion of a slurry. The pressure differential across the screen can be toggled or pulsed. Generally, various types of separators are used to separate liquids and solids. For example, oilfield drilling operations use separators with screens to remove solids from a slurry. One type of apparatus used to remove solids from drilling mud is commonly referred to in the industry as a "shale shaker."

Abstract: A system and method include pumping drilling fluid through a drill string extended into a wellbore extending below the bottom of a body of water, out the bottom of the drill string and into the wellbore annulus. Fluid is discharged from the annulus into a riser and a discharge conduit. The riser is disposed above the top of the wellbore and extends to the water surface. The discharge conduit couples to the riser and includes a controllable fluid choke. A fluid return line is coupled to an outlet of the choke and extends to the water surface. Gas under pressure is pumped into the return line at a selected depth below the water surface. The controllable fluid choke may be operated to maintain a selected drilling fluid level in the riser, the selected fluid level being a selected distance below the water surface.
