Task 3: Pore scale

These are the projects in Task 3.

Project title: Pore scale simulation of multiphase flow in an evolving pore scale
Project manager: Jan Ludvig Vinningland (IRIS)
Objective: To use numerical models in real pore space geometries to investigate the effect of the evolving pore space on permeability, relative permeability and trapped oil. To estimate variations in the predicted values depending on the sample size.

Project title: Improved oil recovery molecular processes
Project manager: Roar Skartlien (IFE)
Objective: To understand the physical mechanisms behind the migration of polymers away from mineral walls and to use this knowledge to make changes in the effective viscosity used at a pore scale and on the Darcy scale.

Project title: Micro-scale simulation of polymer solutions
Project manager: Espen Jettestuen (IRIS)
Objective: To implement a full lattice Boltzmann polymer solver in the BADChIMP code. To study effective rheology in real rock samples in single-phase and multi-phase environments. To study processes for the mobilization of the remaining oil due to the additional forces exerted by the polymer.

Project title: Description of the rheological properties of complex fluids based on the kinetic theory (Postdoc project)
Project manager: Per Amund Amundsen (UiS)
Objective: To construct working mathematical and physical models that allow for the description and prediction of the rheological properties of complex fluids in different circumstances.

Project title: Experimental investigation of fluid chemistry effect on adhesive properties of calcite grains (PhD project)
Project manager(s): Anja Røyne (UiO), Aksel Hiorth (UiS/IRIS) and Shaghayegh Javadi (UiS)
Objective: The object of this project is to study the adhesion force between two calcite grains in contact with a reactive fluid by developing a measurement method using Atomic Force Microscopy (AFM).

Project title: Simulation of complex non-Newtonian flow
Project manager: Bjarte Hetland
Objective:

  • Develop a pore scale simulation tool that is capable of simulating flow of non-Newtonian fluids in complex geometries, including micro channels – taking the tensor nature of these fluids into account.
  • Determine if and when the non-Newtonian effects are important for displacement of oil.
  • Calibrate the model against known analytical and experimental results.

    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.
