The reserve estimation of coal bed methane (CBM) reservoirs is ascertained through the analytical methods (volumetric method, material balance equation and decline curve analysis). However, the adoption of reserve estimation ...

The successful drilling operation depends upon the achievement of target drilling attributes within the environmental and economic constraints but this is not possible only on the basis of laboratory testing due to the ...

Global warming is a key concern for human society and anthropogenic emissions must be reduced. To aid this development, carbon capture and storage has showed a great potential. Here, carbon dioxide is captured and stored ...

Large-scale hydrogen storage can help alleviate the main drawbacks of renewable energy generation, their intermittency, and their seasonal and geographical constraints. Renewable energy without energy storage is unable to ...

Depleted gas reservoirs can provide a gigaton capacity and the necessary infrastructure for large scale hydrogen storage. Therefore, underground storage of hydrogen in these geological formations is considered a valuable ...

We formulated the maximum hydrogen column height that avoids capillary breakthrough into the caprock above saline aquifers and depleted gas reservoirs. The effects of potential cushion gases such as methane, carbon dioxide, ...

Accurately measuring wettability is of the utmost importance because it influences several reservoir parameters while also impacting reservoir potential, recovery, development, and management plan. As such, this study ...

Well path optimisation is often done based on the wellbore stability where the production related concerns are ignored. In fact, many of the studies carried out in the past have not included hydraulic fractures into their ...

With the long-standing efforts of green transition in our society, underground hydrogen storage (UHS) has emerged as a viable solution to buffering seasonal fluctuations of renewable energy supplies and demands. Like ...
