... allowing the casing pressure to build enough driving energy (P C - P L ) sufficient to lift the plunger and liquid load (P C - P T ) to the surface. When the load factor is less than 0.5 the plunger is expected to come to the surface at a reasonable rise velocity. Plunger Rise Velocity and Maximum...
