Depositional environments with sandstone and interbedded shale layers are promising for CO2 storage because they can retain CO2 beneath continuous and discontinuous shale layers. However, conventional numerical simulation of shale–sandstone systems is computationally challenging due to the large ...

Sandstone and minerals were placed on top of one another over the course of millions of years, and when tectonic plates shifted, slanted painted layers appeared on the rock formations and sandstone rolling hills. Along with erosion, these natural occurrences have produced magnificent and ethereal patterns.The Nanaimo Group strata comprise a 5000-metre-thick sequence of conglomerate, sandstone, and mudstone layers. Coal was mined from Nanaimo Group rocks from around 1850 to 1950 in the Nanaimo region, and even more recently in the Campbell River area. The Nanaimo Group is divided into 11 formations as described in Table 6.6.Stimulating offshore sandstone formations with depleted reservoir pressure is a challenge.
