Project title

The impact of hydrocarbon emplacement on carbonate diagenesis

Project description

I am a 2nd year phd student, funded by the Petroleum Technology Trust Fund (PTDF), Nigeria.

The focus of this research is to produce an empirical evidence with a geochemical pore-scale model, that will demonstrate the impact of hydrocarbon emplacement on cementation in carbonate rocks.

Previous studies have highlighted the dynamics of cementation in the presence of hydrocarbon emplacement, establishing the conditions and factors that make oil emplacement to inhibit cementation to preserve good porosity.

But these studies have largely been qualitative and based on petrographic analysis of final rservoir rock properties.

The paleo fluid-rock interactions and exact paleo fluid geochemistry has not been reconstructed and matched with porosity and permeability preservations in reservoirs.

The pore-scale dynamics of cementation will be investigated using core flooding and imaging techniques like the x-ray computed microtomography.

The starting point of the work is with calcite cementation in carbonates, but the plan is to extend the application of the defined controls to other reservoir and cementation types.

The supervisory team consists of Cees Van der Land, Sanem Acikilan, Tannaz Pak (Teeside University), Laura Galluccio (Badley Ashton).
