Figure 7.
Hoop stresses along the boundary of an elliptical (α = 10) kerogen speck. At high pore pressure (Pp ) (Pp = 86 MPa), the hoop stress becomes negative and exceeds the tensile strength of the speck at θ = 0, π, thus creating a horizontal microcrack. σh = horizontal stress; σv = vertical stress.
