Salt Precipitation and Water Evaporation Modelling in a Black-Oil Reservoir Simulator

Salt precipitation is a major issue in gas fields as it may reduce production significantly. Salt precipitation can be triggered through evaporation of the brine into the gas leading to an increased brine salt concentration and - if reaching its solubility - precipitation will occur reducing the rock porosity and, consequently, the permeability....

A detailed comparative performance study of underground storage of natural gas and hydrogen in The Netherlands

With the expected increase in the use of hydrogen as an energy carrier, large-scale underground storage sites will be needed. Unlike underground natural gas storage (UGS), many aspects on the performance of underground hydrogen storage (UHS) are not well understood, as there is currently no UHS in use for energy supply. Here we present the...

A Comparative Study of Hydrogen/Natural Gas Storage in a Depleted Gas Field in the Netherlands Using Analytical and Numerical Modelling

Underground gas storage (UGS) in depleted gas reservoirs plays a vital role today in balancing supply and demand of natural gas and securing energy supply. Similarly, such reservoirs could potentially be (re)used for underground hydrogen storage (UHS). Feasibility studies on hydrogen storage in reservoirs need reliable tools and methodologies to...

A physics-informed optimization workflow to manage injection while constraining induced seismicity: The Oklahoma case

A newly developed modelling framework is presented which specifically focusses on the central Oklahoma case and the high-volume injection of wastewater, which led to a surge of induced seismicity. However, the modelling framework is versatile enough to be applied to any anthropogenic subsurface activities and should be seen as a good practice to...
