1 Subsuface Flow Modeling Martin Blunt and Branko Bijeljic Martin Blunt and Branko Bijeljic Stefan Iglauer Stefan Iglauer Ran Qi Ran Qi Saleh Al-Mansoori, Saif Alsayari

2 Overview Single pore model Single pore model Network model (pore to core scale) Network model (pore to core scale) Lab-scale experiments Lab-scale experiments Preliminary Study of Maureen Field for EOR/CO 2 Storage Preliminary Study of Maureen Field for EOR/CO 2 Storage Developing streamline-based simulator to study CO 2 Storage Developing streamline-based simulator to study CO 2 Storage Working on Design of CO 2 Storage to Trap CO2 Working on Design of CO 2 Storage to Trap CO2

3 Pore Scale: Single Pore Model Lagrangian based model Lagrangian based model Diffusion – advection - reaction Diffusion – advection - reaction Overlap Update Cubic network

4 Pore to Core Scale: Network Model Use Network Libraries to describe pore space Use Network Libraries to describe pore space Multiphase flow, dispersion and reaction Multiphase flow, dispersion and reaction MEAN FLOW DIRECTION X

5 Pore to Core Scale: Column Experiments

6 Field Scale: Maureen Field for EOR/CO 2 Storage Oil Saturation Maureen field – Preliminary study using Eclipse Maureen field – Preliminary study using Eclipse –Abandoned sandstone reservoir –413 million barrels (1.5x10 8 m 3 ) oil –Simulate injection of CO 2 after waterflooding

7 Maureen – Long Term Fate How to contain CO 2 : How to contain CO 2 : A) Dissolution CO 2 dissolves in water timescales 1000-year B) Reaction carbonate precipitation B) Reaction carbonate precipitation timescales 10 3 – 10 9 years C) Trapping CO 2 as pore scale droplets timescales decades surrounded by water

8 Maureen - Conclusions CO 2 and water injection increased oil recovery by 5-10% CO 2 and water injection increased oil recovery by 5-10% This represents up to 1billion pound revenue from increased oil production while storing over 55 million tonnes of CO 2 This represents up to 1billion pound revenue from increased oil production while storing over 55 million tonnes of CO 2 This is equivalent of all the CO 2 produced from all activities from the population of London in a year This is equivalent of all the CO 2 produced from all activities from the population of London in a year In the future, these strategies could be applied to other North Sea fields In the future, these strategies could be applied to other North Sea fields

9 Field Scale: Developing streamline-based simulator to study CO 2 Storage SPE10 test – STREAMLINE SPE10 test – STREAMLINE WAG injection producer injectorproducer 82.5% CO 2 can be trapped as an immobile phase WAG injection for better sweep efficiency

10 Collaborations Are there any reservoir descriptions that you would like to share for flow studies?
