Changes

The top seal of the ''Glob alt'' reservoir is especially effective because it is thick and has a regional extent as a consequence of its position at a third-order turnaround from regression to transgression. This turnaround is from regressive cycles 3.4–3.5–3.6 to transgressive cycles 3.7–3.8 on the Haq et al.<ref name=ch04r43>Haq, B., Hardenbol, J., Vail, P., R., 1988, Mesozoic and Cenozoic chronostratigraphy and cycles of sea-level change: SEPM Special Publication 42, p. 71–108.</ref> cycle chart ([[:File:Sedimentary-basin-analysis_fig4-25.png|Figure 3]]).

Despite its regional extent and thickness, hydrocarbons have leaked upward into the ''Hyal B'' and ''Trim A'' reservoirs, most probably along faults during intervals of fault movement with consequent dilation of fracture networks along the fault
