... in the DJ Basin, whereas half are located in the Wattenberg Field (marked by the green dashed curve). This makes DJ Basin, especially the Wattenberg field, a good target for carbon storage. The stacked formations of oil/gas reservoirs and saline aquifers in the DJ Basin are potential CO 2 storage...

... From Kumar and Ramey (1974) and Kumar (1977) , Dimensionless Time, 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...

... consumption, the volumes needed are so high that underground storage options such as salt caverns, depleted oil/gas reservoirs, and aquifers, become appealing. Abstract Hydrogen (H 2 ) is an attractive energy carrier and its true potential is in decarbonizing industries such as providing heat...

... 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 cost compared to the other techniques. Most of the ethanol plants are located on the eastern side of the state, while geological evaluation...

... 1.00 1.00 0.00 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...

... in the storage aquifer. The emplaced CO 2 amount at the beginning is 0.51 PV, with the same initial saturation as H 2 in Fig. 4 . Figure 7 Mixed H 2 and CO 2 is emplaced at the bottom at the beginning of buoyant flow with two volume ratios of 1:1 (a) and 1:3 (b). Both the gas saturation and global...

..., the pressure trend continued bending upward, and a straight line p/Z plot, characteristic of volumetric gas depletion without aquifer support, was not seen. The question arises whether there is still undrained volume or whether pressure support from the aquifer has already observed. Assuming a weak water drive...
