Research topic: "Chemical Additives to Steam Injection:  Testing New Generation Chemicals and Conventional Surfactants"

Thesis

​

Performances and efficiencies of thermal and gravity driven recovery methods for reservoirs containing heavy oil have been investigated over the last decades. It is well known that these methods result in high energy consumptions, demand of fresh water resources and high cost of surface facilities. This research is based on the evaluation of enhancement in the mentioned drawbacks by using different chemical additives in gravity driven steam injection processes. An experimental set-up is designed to simulate the steam assisted oil recovery and examine different effects of new generation chemicals on high viscous oil under high temperature and pressure conditions. The obtained data from the experiments would then lead to suggestions of new efficient production methods that are technically and economically advantages as well as to interpretations of interfacial interactions of steam/oil/chemical.
