Alteration of the weakly weathered shale (Zone A) is attributed to the 40-a exposure of the shale.May 16, 2022 · Shale is of strong heterogeneity. The mineral composition has a significant influence on the diagenetic evolution, pore network formation, hydrocarbon content, oil mobility, and reservoir stimulation of shale. Accurate mineral analysis of shale is an essential precondition for scientific research and industrial production. In this study, we present a new quantitative method for shale mineral ... Despite the advances achieved in addressing the CO 2 /shale interaction, the impact of SCCO 2 treatment on shale mineralogy, surface morphology, chemistry, and wettability needs further investigation. To date, only few studies have evaluated the changes in the physical and chemical properties of shale mineralogy.Oct 8, 2021 · The mineralogy study is critical to explain the shale softening mechanism based on the clay content of shale. A more significant clay-water reaction is expected with higher clay contents in a ... This is due to a high content of soft clay minerals, which are only weakly cemented in typical shale and mudstone. Mudstones and shales commonly occur ...Peter, J.M.; Scott, S.D. 1991: Mineralogy and geochemistry of the Windy Craggy copper-cobalt-gold massive sulphide deposit, northwestern British Columbia, Canada Open-File Report - Geological Survey of Canada: 31-67..
