Task 2: Mineral fluid reactions at nano/submicron scale

These are the projects in Task 2.

Project title: Micro- and nano-analytical methods for EOR (PhD project)
Project manager(s): Udo Zimmermann (UiS), Merete Vadla Madland (UiS) and Mona Wetrhus Minde (UiS)
Objective: This project focuses on understanding EOR mechanisms at a sub-micron scale using several state-of-the-art micro- and nano-analytical techniques. Imaging and analyses of texture and chemistry to describe alteration in sedimentary rocks due to flooding with non-equilibrium brines.

Project title: Raman and nano-Raman spectroscopy applied to fine-grained sedimentary rocks (chalk, siltstones and shales) to understand mineralogical changes for IOR application (PhD project)
Project manager(s): Udo Zimmermann (UiS), Sergio Andò (Università Milano Bicocca) and Laura Borromeo (UiS)
Objective: The project aims to increase knowledge of Raman spectroscopy applications for EOR processes and the understanding of mineral identification. Through the combination of micro- and nano-Raman and AFM, we will be able to identify the mineral phase and visualize the area. The project will concentrate on the aspect of mineral growth, its predictability in chemical sedimentary rocks and the effects of flooding experiments on reservoir chalk, as well as possible clastic rocks.

Project title: Applying the analytical tool box to specific EOR related experiments to enhance oil recovery and to assist upscaling
Project manager: Udo Zimmermann
Objective: To understand Smart Water effects at micro- and nano-level and link these alterations to changes in geo-mechanical parameters of reservoir rocks, now on specific applied areas: fractures, the role of clays/non-carbonate minerals and high porosity zones. These data will be crucial for upscaling of Smart Water.

    Task 1: Core scale

    Task leader: Arne Stavland, NORCE

    The aim of this task is to design novel experiments on core scale and develop models that capture the transport mechanisms observed. The deliverables of this task will be chemical systems that can improve the microscopic and microscopic sweep on clastic and chalk fields.

    Task 2: Mineral fluid reactions at nano/submicron scale

    Task leader: Udo Zimmermann, UiS

    The research focuses on rock-fluid interactions when injecting fluids into rock formations, clastic or chemical sedimentary rocks. We use electron microscopy, Raman spectroscopy, specific surface area measurements and X-Ray Diffraction for further investigations of EOR related experiments. The geology of the hydrocarbon bearing formations plays a significant role.

    Task 3: Pore scale

    Task leader: Espen Jettestuen, NORCE

    The focus in this task is to study the interplay between fluid transport, mineral reactions and oil recovery in reservoir rocks at pore scale. The main aspects are to identify the mechanisms that influence transport and reactions on the pore scale using experiments and numerical modeling, and then to evaluate if these mechanisms are important on the core scale.

    Task 4: Upscaling and environmental impact

    Task leader: Aksel Hiorth, UiS/NORCE

    The main objective is to translate the knowledge we have about EOR processes on core scale to field scale. The deliverables from this task will be simulation models and work flows that can be used to design IOR operations and interpret IOR implementations.

    Task 5: Tracer technology

    Task leader: Tor Bjørnstad, IFE

    The objective is the development of tracer technology to measure reservoir properties and (changing) conditions during production. The most important condition is the (remaining) oil saturation, either in the flooded volume between wells (interwell examinations) or in the near-well region out to some 10 m from the well (single-well huff-and-puff examinations).

    Task 6: Reservoir simulation tools

    Task leader: Robert Klöfkorn, NORCE

    The primary objective of this task is to advance the state-of-the-art of modeling and simulation in context of reservoirs. Such advance is needed to cope with the challenges arising from scientific questions and targets of The National IOR Centre of Norway.

    Task 7: Field scale evaluation and history matching

    Task leader: Geir Nævdal, NORCE

    We do history matching using 4D seismic data, tuning reservoir parameters to obtain reservoir models that are matching actual observations. We are using ensemble based methods, running with a set of different realizations of the parameter set and use statistical methods to tune the parameters. The outcome is models that are aligned with actual observations.
