The Bodalla South field, Eromanga basin, Australia, has short oil columns—less than [[length::12 m]] high—that appear to be limited by the displacement pressure of the top seal.<ref name=ch10r6>Boult, P., J., 1993, Membrane seal and tertiary [[migration pathway]]s in the Bodalla South oilfield, Eronmanga Basin, Australia: Marine and Petroleum Geology, vol. 10, no. 1, p. 3–13., 10., 1016/0264-8172(93)90095-A</ref> [[:file:evaluating-top-and-fault-seal_fig10-53.png|Figure 1]] shows the top seal and oil accumulations. The top seal, the Birkhead Formation, consists of fluvial channel and point bar deposits as well as more shale-prone levee bank, crevasse splay, floodplain, and coal swamp facies. Measured displacement pressures of the top seal have an average range of 150–200 psi (air-mercury) and can seal 10.86–12.64 m of oil. The maximum height of the actual trapped oil column is [[depth::11.25 m]].
