Task 4: Upscaling and environmental impact

These are the projects in Task 4.

Project title: IORSim development project
Project manager(s): Jan Sagen (IFE) and Aksel Hiorth (UiS/NORCE)
Objective: To develop a simulator that uses industry standard reservoir models and the important physio-chemical mechanism from the lab scale to predict the impact of an IOR strategy.

Project title: Environmental fate and effect of EOR polymers (PhD project)
Project manager(s): Eystein Opsahl (UiS), Roald Kommedal (UiS) and Aksel Hiorth (UiS/NORCE)
Objective: To provide understanding about the behaviour of polymers used for EOR in the marine environment at low concentrations. This will be done by applying modern toxicological methods, well-established tests used in environmental risk assessment and state-of-the-art analytical techniques based on light scattering.

Project title: Lab scale Polymer Test in porous media - Supporting Halliburton’s Large Scale Polymer Shear Test phase II
Project manager(s): Siv Marie Åsen (NORCE) and Amare Mebratu (Halliburton)
Objective: Lab work supporting and supplementing Halliburton’s large-scale phase II test and IRIS personnel’s involvement in the large-scale test. A detailed experimental test design for the large-scale phase II test is in progress and will focus on the shear degradation of polymers in a porous media. Support will be required from
IRIS researchers in designing the test set-up, carrying out sampling and measuring and interpreting the data. We will also perform lab-scale experiments using similar systems to those used in the large-scale test.

Project title: Smart Water for EOR by Membranes (PhD project)
Project manager(s): Torleiv Bilstad (UiS)
Objective: The main objective of the project is to produce smart water from seawater and produced water (PW). A second objective includes evaluating the proper pre-treatment of PW. Produced water treatment includes oil removal and a reduction in total dissolved solids

Project title: Polymer rheology at micro- and Darcy scale
Project manager: Siv Marie Åsen
Objective: The primary objective is to perform dedicated experiments at micro and Darcy scale to verify/
substantiate or reject models that explains the behaviour of polymer solutions in porous media.
In addition to traditional investigation, the polymer will be studied with novel/advanced techniques such as microfluidics, imaging techniques and instruments for analysing the distribution of molecular weight. This will be done in cooperation with ongoing projects in the IOR Centre. Modelling tools devolved in the Centre will be used to model the polymer behaviour at pore scale, lab scale and field scale. Results from phase II of the large-scale polymer test can be included.

Project title: Risk Management/ERA
Project manager: To be decided
Objective: To develop tools for risk-informed decision-making related to IOR solutions developed at the Centre. This project will connect with the other research activities in the Centre by gathering information about the solution developed, assessing the associated environmental risk, and providing decision support to the further R&D activities. It will thus be an activity that runs through the entire Centre activities.

Project title: Improve IOR models in IORSim
Project manager: To be decided
Objective: Improve IOR models in IORSim to predict the behaviour of IOR chemicals in realistic field cases.

  • Arne Stavland

    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.

  • Aksel Hiorth

    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.

  • Tor Bjørnstad

    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.

  • Geir Nævdal

    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.
