Is it feasible to find an actual field scenario, where primary imbibition occurs associated with a petroleum reservoir?

Background:

Primary imbibition refers to the imbibition process commencing @ 100% non-wetting phase saturation; and the respective curve completely falls within the negative capillary pressure region unlike a primary drainage curve or a secondary imbibition curve or a secondary drainage curve; and the magnitude of this (negative) capillary pressure for primary imbibition nearly remains as a constant for the water saturations from 0 until it becomes equal to (1-residual_oil_saturation).
