The Effects of Dissolved Sodium Chloride (NaCl) on Well Injectivity during CO2 Storage into Saline Aquifers
Abstract: Among different options proposed for carbon dioxide (CO2) storage and sequestration, saline formations seem promising due to their wide availability and potentially large storage capability. As supercritical (SC) CO2 is injected into the formation, a variety of coupled processes takes place. Halite precipitation requires particular interest due to its potentially significant impact on permeability impairment, and thus reduction of injectivity in the near well bore region. The selected candidate for …

Predictability of Equation of State (EoS)-based Gas Hydrate Models for Single and Binary Gas Mixtures
Abstract: The better models are necessary to design and understand the phase behavior of produced trapped natural gas from natural gas hydrates from subsea environments. Most of the models available in an open literature are primarily applicable at relatively low pressure condition thus making their use very limited for gas hydrate reservoir modeling. In order to produce methane from these gas hydrates, it is important to understand the phase behavior through …

Prediction of Punching Shear Capacity of Biaxial Voided Slab
Abstract: Biaxial voided slab systems are advantageous due to their reduced self-weight, up to 50 % in comparison with the conventional reinforced concrete solid slab. The reduction in the concrete cross sectional area reduces the shear capacity up to about 40 %. The prediction of punching shear capacity in voided slab is not direct unlike in solid slab. This is because the presence of voids alters the critical failure section and …
