The right stimulation surfactant can deliver greater well performance, and surfactant performance should be evaluated under simulated wellbore conditions. The Amott Cell Spontaneous Imbibition test achieves this by measuring the oil displacement of crude oil through water imbibition. See the video below for a demonstration of Amott Cell testing.

The brines were also heated to 70°C. The plugs were then removed from the glass jars, rolled in dry tissue paper to remove any excess crude, weighed, immersed in brine, transferred to the Amott cell, and returned to the oven at 70°C. Production of oil was then recorded as a function of time until total oil production reached a plateau.
