In secondary migration, what is the specific pressure difference required for a hydrocarbon droplet to deform and pass through the pore throat of a carrier bed?

The pressure difference required for a hydrocarbon droplet to pass through a pore throat during secondary migration is defined by the capillary entry pressure. This pressure occurs because the pore throat is narrower than the droplet, forcing the droplet to deform. To move through the constriction, the droplet must develop an interface curvature that matches the radius of the pore throat. The s....
