EXPERIMENTAL VERIFICATION OF OIL SATURATION AND LOSSES DURING SECONDARY MIGRATION

Accurate estimates of losses occurring during secondary petroleum migration are of vital importance for valid petroleum systems assessments. In this paper, we discuss the development of migration pathways and the corresponding hydrocarbon losses using data from laboratory experiments based on diphasic immiscible draining processes. These experiments permitted us to study the formation of migration pathways, the distribution of non‐wetting oil along these pathways, and the re‐utilization of existing pathways by later pulses of migrating oil.
