Is this a viable mechanism for oil migration?
As most water expulsion takes place in clay sediments in the first 2 km of burial and taking into account an average geothermal gradient, oil generation occurs beneath this depth. Would the simple flushing of oil with expelled water be a viable mechanism for primary or secondary migration?

Leigh Price did a huge study on this in the 1970's published in the AAPG Bulletin and this mechanism is possible if not likely for at least some hydrocarbon migration. The truth is that we really don't know all the ways oil and gas can migrate
