Abstract
A plug for use in wellbore operations includes a plug body extending from a top end to a bottom end; a sealing member as part of the plug body and positioned at the bottom end; and a non-rotating profile positioned at the bottom end of the plug body; the sealing member protrudes past the non-rotating profile such that the sealing member comes into contact with a surface when the plug is dropped into a well before the non-rotating profile.
