  • Qatar Carbonates and Carbon Storage Research Centre:Status update after three years of fundamental research

    Nasser al-Mohannadi and Jurgen Foeken

    Qatar Petroleum Research and Technology CentreDoha, Qatar

  • Overview

    2

    • research partnership between QP, Shell, QSTP and

    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

    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

    Qatari nationals conducting PhD studies at ICL

    QCCSRC establishing a presence in Qatar

    Move of lab equipment to QSTP; start 2013 with move of HPHT interfacial tension rig,expanding in years after

  • Conclusions

    Acknowledgements: Iain McDonald, Program manager QCCSRC, for support inpreparing publication

    $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
