There is a growing interest in developing CO2 capture processes based on phase separation solvents due to its much lower energy consumption compared the reference amine process using monoethanolamine (MEA). In this work, predictive COSMO-SAC activity coefficient model was applied describe behavior for solvent composed of + water glycol ether. From calculated ternary liquid-liquid equilibrium (L...

I welcome the comment by Alendal et al. (1), and the opportunity to clarify some issues. My paper (2) focuses on theoretical calculation of the dissolution rate of a single rising CO2 droplet (or noninteracting droplets) in the context of carbon sequestration in oceans. The calculated dissolution rate agrees with the in situ experimental data of Brewer et al. (3). The comment (1) does not raise...

Reservoir depletion and subsequent CO2 injection into the depleted geological reservoir induce stress changes that may mechanically damage top seal and wells, or trigger existing faults, creating the leakage pathways for CO2 escape from the reservoir. The role of geomechanics is to assess the mechanical impact of stress changes on seals, wells and faults. Since many hydrocarbon fields are geome...

The injection of supercritical CO2 in deep saline aquifers leads to the formation of a CO2 plume that tends to float above the formation brine. As pressure builds up, CO2 properties, i.e. density and viscosity, can vary significantly. Current analytical solutions do not account for CO2 compressibility. In this article, we investigate numerically and analytically the effect of this variability o...

We present here the way to bring together two open source modellers, PhreeqC and Elmer, with disjunctive application fields. They are gathered in a single environment to enable multi-component, reactive solute transport studies in threedimensional saturated/ unsaturated ground-water flow systems. The choice of Python as programming environment is explained, the way the tools become so called Py...

In this paper we describe CO2-PENS, a comprehensive system-level computational model for performance assessment of geologic sequestration of CO2. CO2-PENS is designed to perform probabilistic simulations of CO2 capture, transport and injection in different geologic reservoirs. Additionally, the long-term fate of CO2 injected in geologic formations, including

The aim of the current study is to evaluate the effects of inhibitors or solvents on asphaltene precipitation under reservoir conditions. To this end, the interaction between live oil and solvent, and its side effects on precipitated/dissolved asphaltene were predicted via Miller’s entropy modified polymer solution theory under reservoir conditions. Then, the adjustable parameters of the model ...

The application of enhanced oil recovery (EOR) in offshore oil fields has received significant attention due to the potentially enormous amount of recoverable oil. However, EOR application offshore is in its very early stage due to conditions that are more complex than onshore oil fields, owing to the unique parameters present offshore. Therefore, successful EOR applications in offshore oil fie...
