Upscaling and environmental impact

What are the most important parameters from smaller scales that are important to describe flow on a larger scale? Chemical EOR methods have proven their potential on core scale. But, additional oil produced at the core scale does not necessarily imply that the field recovery will be similarly increased.

Task leader: Aksel Hiorth, Professor, UiS (aksel.hiorth@uis.no)

In this task there are three research projects, and three PhD projects, one PhD student has defended her thesis, and Siv Marie Åsen will defend her thesis 30 June 2021. The IORSim project is a collaborative effort between IFE, NORCE, and UiS to develop a simulator that can bridge the gap between the research prototype simulators and industry standard reservoir simulators. We work continuously to improve the user friendliness of IORSim, including testing the GUI of IORSim. A postdoc, Felix Feldman, is a new addition to the IORsim team and has already done great progress and is currently simulating the Snorre silicate injection on the actual Snorre sector model using IORSim.

The large (yard) scale project is led by Halliburton with a very good collaboration with activities in Task 1. Since last time Thermo-Thickening associative polymers (TAPs) have been tested and the results at Haliburton is consistent with lab results at Norce. The coordination of upscaling workflows has held several meetings and the project has been an active part in 3 delivery forums: Polymer, Smart-Water, and Upscaling. Together with project 1.1.1, an initiated activity in project 2.7.1 led by Alexey Khrulenko investigates how the advanced IORCoreSim polymer models can be mimicked in Eclipse. Early results are promising, it is possible to use IORCoreSim to generate tables that can then be used by ECLIPSE.   

A similar activity has been initiated in project 1.1.15, Intersect was used first, but them it was decided to focus on OPM. The well model in OPM is being extended to account for degradation in the near well area. We expect one additional PhD thesis, Eystein Oppsahl, on biodegradation of polymers to be submitted within a couple of months. The last PhD thesis by Mehul Vora, has funding until 2022 and will submit after the Centre is official finished.
