Evaluation of hydrocarbon migration pathways by using GOI technique

By Zartasha Riaz

The complex structural evolution of Mezősas and Mezősas West Fields, East Hungary, make it challenging to predict the presence of hydrocarbons. The GOI technique (grains containing oil inclusion) determines the ratio between grains containing oil inclusion(s) and the total number of grains (GOI %), combined with conventional hydrocarbon (HC) indicators is a fast and cost-effective way to distinguish HC migration pathways from oil columns and water-zone. The threshold of GOI 5% separates paleo-oil columns from the residual zones and migration pathways, and the paleo-oil water contact (OWC) is marked by the sharp decline of GOI values. Sandstones and conglomerates with various textures and compositions underwent significant compaction, dissolution, quartz and carbonate cementation. Hydrocarbon migration is one of the latest diagenetic event. The GOI values (
