Figure 12.
The image presents two sets of cylindrical models representing data across various stages. The top section contains three models labelled A, B, and C, each showing distinct gradient patterns over a 60 day period. The data is visualised through layered colours indicating different values. The right side of this section includes a legend showing invariant p values, with numerical ranges from 9 to 8.1667. The bottom section focuses on Model A, illustrated through four cylindrical models showing different stages, at 60 days full saturation, at 90 days during gas injection, at 118 days labelled as first gas B T, and at 160 days labelled as second gas B T. Each cylinder displays a unique gradient representing data transformation over time. The left side includes a similar legend for invariant p values, ranging from 8.778 to 3.722.Mean total stress distributions at the end of saturation phase in three models (a), mean total stress distributions in Model A (b) at the end of saturation (60 days), during gas injection (90 days), during the first BT (118 days), and during the second BT (160 days).
