Avoiding Damage of CO2 Injection Wells Caused by Temperature Variations

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487346

Well integrity is a prerequisite for safe geological storage of CO2. Both active and abandoned wells are man-made channels between the storage reservoir and the atmosphere that can become leakage paths over time. The CO2 injection wells are of special concern, as they are exposed to low temperatures...

Towards a thorough Validation of Simulation Tools for CO2 Pipeline Transport

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1489484

In this work the Schlumberger flow assurance tool OLGA and SINTEF Energy Research in-house CFD tool are assessed for their ability to describe depressurization behaviour of CO2 pipelines. For this purpose, three full-bore experimental depressurization tests with pure CO2 have been performed at the S...

Thermodynamic modeling with equations of state: present challenges with established methods

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1457656

Equations of state (EoS) are essential in the modeling of a wide range of industrial and natural processes. Desired qualities of EoS are accuracy, consistency, computational speed, robustness and predictive ability outside of the domain where they have been fitted. In this work, we review present ch...

The influence of CO2 mixture composition and equations of state on simulations of transient pipeline decompression

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1369968

In a CO2 transport pipeline, decompression can occur either due to planned maintenance or accidental rupture. We investigate the impact of modelling simplifications and assumptions regarding the purity of CO2 on the decompression of an industrial scale transport pipeline. Using industrially relevant...

A large time step Roe scheme applied to two-phase flow

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1392319

We consider a large time step (LTS) Roe scheme, originally suggested by LeVeque [Comm. Pure Appl. Math., 37(1984), pp. 463-477] which has attained increased popularity in recent years. The scheme is based on a wave formulation of the ordinary Roe scheme, and the assumption that waves interact linear...
