2. When opening or closing, the stage collar is designed in such a way that liquid does not accumulate in the loculum (a small compartment or chamber). This design prevents any liquid from obstructing or interfering with the proper functioning of the stage collar during operation.
3. To protect the body of the stage collar from damage during drill-out operations when the drill bit goes down, it is important for the inner diameter (I.D.) of the upper and lower sub to match that of the casing. This ensures a protective barrier is formed, reducing the risk of potential damage.
