... Abstract Secure and safe geological sequestration is critical for the successful deployment of carbon capture and storage (CCS) projects and to mitigate global warming. Oil/gas reservoirs and saline aquifers, that are suitable for CO 2 sequestration, often have older pre-existing wells near...

... Abstract This paper presents a new concept of Pseudo-Aquifer Index and a major departure from classical methods to estimate transient water influx using Kumar-Ramey equation employing reservoir average pressure obtained from transient tests for a central well in a constant pressure reservoir...

... underground storage: lined caverns, salt domes, saline aquifers, and depleted oil/gas reservoirs where large quantities of gaseous hydrogen can be safely and cost-effectively stored and withdrawn as needed. Underground geologic storage must have adequate capacity, ability to inject/extract high volumes...

... Abstract Carbon capture utilizations and storage strategies (CCUS) have recently attracted many interests to mitigate the global warming and reducing CO 2 emission in the atmosphere. Injecting CO 2 into the depleted hydrocarbon reservoirs and aquifers has been focused as one the main CCUS...

... of a robust hydrogen economy. The required hydrogen storage capacity will be much larger than current hydrogen and natural gas storage capacities. There are a several geological storage options for hydrogen that include depleted hydrocarbon fields and aquifers, where more research is needed until...

... to capture and sequestrate the emitted CO 2 , including mineral carbonation and carbon geological storage. Among these techniques, carbon geological storage is the most feasible option, especially sequestration in deep saline aquifers because of the larger volume that can be stored underground, and lower...

Abstract The objective of this study is to better understand the baseline aqueous chemistry and provenance of all groundwaters from the near surface shallow aquifers to the deeper Vaca Muerta shale ~ 2000 m depth subsea in the Neuquén Basin for water disposal monitoring. The regions included...

... production wells were equipped with a permanent downhole gauge (PDG) to obtain near-bottom hole pressure data. A p/Z plot [ 1 ] of the pressure data exhibits a non-linear trend suggestive of pressure support from the aquifer or, perhaps, an adjacent gas reservoir in restricted communication with the main...

In addition to their primary use, they are effective to decide on the optimal rate of the wells and to investigate the existence of alternative water sources (different from the underlying aquifer). The Water Towers model is part of the toolbox...
