Cap Rock Integrity Degradation in Geosequestration of CO2 in Depleted Petroleum Reservoirs

Project Description

Robert Gordon University, through the School of Engineering is offering a PhD studentship with tuition fees funded for Home/EU or International applicants.

This is a fees-only funded PhD studentship provided by the School of Engineering and interested candidates will have to secure their own financial support to upkeep their living costs.

Reduction and ultimately elimination of industry-based greenhouse emissions are at the forefront of almost every developed countries around the world. As evidenced in Paris agreement of 2015, all the parties to the United Nations Framework Convention on Climate Change agreed on intensifying their efforts and investments toward a net zero carbon future for the world. One strategy that is core to addressing this challenge is the geosequestration of the CO2 within depleted hydrocarbon reservoirs. Such reservoirs originally contained pressurized gas for long geological times due their natural caprock sufficient integrity. However, this fact does not guarantee that the reservoir cap rock is still capable of containing the injected CO2. Fluctuations of stress and strain within cap rock over the production life cycle of the reservoir should be thoroughly investigated. Pressure release consequences on cap rock strength depends on cap rock mineralogy and rock mechanical behaviour of it at microscopic levels as well as macroscopic deformations.

This research is aimed at investigation of cap rock integrity under such cyclic stress loadings through laboratory analyses at core plug and microscopic scales in addition to numerical study of various associated time-dependent effects during production depletion and re-pressurization. A sensitivity analysis is required to enable composing a screening tool for best depleted reservoirs to be shortlisted as CO2 storage sites and ensures maximum safety and efficiency of injection operation.

Applications should be emailed to Dr Reza Sanaee at . The applications should consist of a covering letter or personal statement of interest, and a CV.

Deadline for receipt of applications is 15th April 2020.

It is expected that candidates are available to register and commence study in October 2020.
