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

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

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

$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
