Abstract
Selectively actuated plungers and systems and methods including the same are disclosed herein. The methods include flowing a wellbore fluid stream in fluid contact with a plunger and in an uphole direction within a wellbore conduit while the plunger is located within a target region of the wellbore conduit. The methods further include maintaining the plunger in a low fluid drag state while a variable associated with the wellbore fluid stream is outside a threshold range and transitioning the plunger to a high fluid drag state responsive to the variable associated with the wellbore conduit being within the threshold range. The methods further include conveying the plunger in the uphole direction within the wellbore conduit. The systems include the plungers and/or hydrocarbon wells that include the plungers.
