Imperial
• expand fundamental research
• providing improved tools for carbon sequestration
• steer fundamental research by samples / data /
observations from sequestration studies
• build local capacity (currently 5 Qatari PhD students)
• transferring knowledge and technology
QP, Shell and QSTP
Objectives
3
Targeted research over 10 years and $70 million
Aim: Improve Oil Recovery and Carbon Storage in Carbonate Reservoirs
The Strategy:- Characterise & understand the Qatari reservoirs in depth- Develop state-of-the art reservoir multiphase flow simulators- Use to design optimum CO2 storage and oil & gas recovery processes- Validate with ‘Field-scale Laboratory’
Long-term fate of CO2

Qi et al, 2009
Challenges
Site selection- reservoir, seal- fundamental understanding of
subsurface geology
Injection and plume movement- Multiphase flow- Reactive flow- Capillary Trapping- Dissolution Trapping
Monitoring- storage management/regulation
5
Fundamental Carbonate Reservoir & Seal (Project 1)
Reconstruct the sequence stratigraphic framework of Qatari reservoirs using outcrop
analogues in Oman
Identify predictive geological rules and appropriate physical, chemical and mechanical
properties of fractured carbonate reservoirs (including fracture related digenesis / dolomite
bodies) and the in situ fluids
Emphasising fieldwork and state-of-the-art equipment (Clumped Isotope)
6 Papers, 26 conference presentations
Research results

Reservoir pore/fracture scale physics and chemistry (Project 2)
Experimental flow data at reservoir conditions of scCO2 in porous media (especially
carbonates) not sufficient to guide decision makers.
Expand understanding of phase equilibrium, viscosity, interfacial tension, diffusion at
reservoir conditions involving scCO2 / brine / hydrocarbons
Unique linkage of molecular-pore-core scale experiments and modelling
Emphasis on state-of-the-art experimental measurements (9 HTHP rigs, planning HTHP
rel.perm with in-situ monitoring) to validate models
27 Papers, 48 conference presentations
Research results

Research results
Integrated simulator for carbonate reservoirs(Project 3)
Integrated Methodology and Simulator tools
Apply new tools for CO2 predictive modeling, fractured reservoirs, finite elementadaptive meshing and geochemical modelling
Incorporate the detailed reservoir and fluid characterizations and underpinning physicsand chemistry developed in Projects 1 and 2 into an integrated reservoir simulatorcustomised to Qatari reservoirs
Use the simulator/simulation technology to design and optimize new improved recoverystrategies and CO2 sequestration operations
4 Papers, 6 conference presentations
Capacity building

$70 million, 10 year research partnership between Qatar Petroleum, Shell, QatarScience and Technology Park and Imperial College London; one of the largest sciencedriven coordinated academic-industry collaborations
50 academic staff, postdoctoral researchers and PhD students engaged
program addresses the key science and engineering challenges for the safe andpermanent storage of CO2 in carbonate reservoirs, as well as delivering enhance oiland gas production
research focus is on carbonate reservoir characterisation in relevant outcrops, rock-fluid- CO2 interactions and multiphase flow experiments under reservoir conditionslinked to complimentary simulation and modelling advances
knowledge and technology transfer is a critical foundation to the partnership
