What is the primary function of a circulation device?

To facilitate change out of completion fluids prior to perforating under drawdown.
To spin fluids downhole to assist production.
To provide a communication path between tubing and tubing/casing annulus
To allow the well to be gas lifted.
4

Why we use pseudo-pressure for gas wells in particular?

To make analysis more complex
We could use both (pressure or pseudo) always.
Because total compressibility depends on pressure
All of the above
