One of the critical aspects of hydrocarbon exploration across the basin is determining ... Shales are most often used in geologic storage as a confining zone or caprock though recent investigations have shown potential for select shale formations to be used for CO 2 storage. Atlas V presents a map of these potential future storage opportunities, but provides no CO 2 storage resource values for organic-rich shale basins.Mar 30, 2022 · Horizontal drilling is an effective way to increase the capacity of shale formations. However, in the horizontal shale drilling, the major difficulties are the problems of the wellbore stability and the well collapse prevention. In this paper, a jointed-material model is adopted to simulate the strength anisotropy and the permeability anisotropy of the bedding shale. The model is used to ... Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time.
