Green high performance systems for Enhanced Oil Recovery

Updated: 2016-11-29 | Print

In order to meet the growing energy needs in today’s society, petroleum recovery from existing reservoirs must increase. Overall, only about 40% of the petroleum present in known reservoirs is economically recovered with established technologies (primary-recovery methods using natural reservoir forces, and secondary-recovery methods by water/gas flooding). In order to increase recovery, so-called tertiary-recovery methods are required, also referred to as enhanced oil recovery or EOR.

The objective of the GreenEOR project is to contribute to enhanced oil recovery in a sustainable manner, by developing a novel series of green fluids for chemical EOR applications based on nanocellulose, alone or in combination with other EOR components. Nanocellulose is a group of nanoscaled particles produced from wood, and is thus a sustainable and green resource. Nanocellulose has a promising potential as a green flooding additive due to several properties such as e.g. excellent viscosifying and shear thinning properties, hydrophilic nature, excellent possibilities for chemical modification and also robustness compared to dissolved polymers. The potential of nanocellulose as an EOR additive will be explored in the GreenEOR project. The development will depend on close cooperation between different research areas comprising nanocellulose, surface interaction, rheology and core flooding.

The project is led by PFI and the R&D partners in the project are PFI, NTNU – Department of Petroleum Engineering and Applied Geophysics and NTNU – Ugelstad Laboratory.

The project is funded by the Research Council of Norway through the Petromaks 2 programme.
