A Tight Hole is a section of a wellbore where drilling tools with large diameters face resistance. It is basically an open hole. Stabilizers, drill collars, drill pipe, tool joints or parts of a drill string face resistance when a driller drills through a tight hole.
Not to be confused with trolls suffering from a tight hole syndrome during Squeaky bum time. They are currently suffering on account of Saffron, and tend to be very uptight. Bless'm.
In the true spirit of Xmas, cut off their oxygen, and filter them.
