==Well-log cross section==

[[:file:sedimentary-basin-analysis_fig4-48.png|Figure 6]] is a well-log [[cross section]] of the ''Glob alt'' reservoir interval; datum is a mudstone within the GA-2 sandstone (well locations are shown on [[:file:sedimentary-basin-analysis_fig4-46.png|Figure 1]]). All logs are spontaneous potential with true vertical depth displays. The GA-4 reservoir sand is below the displayed interval. Log profiles are annotated: arrow C = funnel-shaped, coarsening-upward sandstone; arrow F = bell-shaped, fining-upward sandstone; parallel lines B = blocky profile of relatively thick sandstones and thin mudstone interbeds.

Well-log correlations within the ''Glob alt'' [[isochron]] thick show a succession of [[Well_log_sequence_analysis#Parasequence_stacking_patterns|aggrading]] sandstone bodies ([[:file:sedimentary-basin-analysis_fig4-48.png|Figure 6]]). [[:file:sedimentary-basin-analysis_fig4-49.png|Figure 7]] shows net sandstone isopachs for reservoir units of the ''Glob alt'' sandstone interval. The stratigraphic succession from top to bottom reservoir sandstone is 1, 1.1, 2, 2.2, 3, and 4. Maps of each sandstone interval document lobate deposition within the minibasin. Individual lobe development shows compensation lobe switching as progressively younger deposits infill the mud-rich/sand-poor intralobe areas of the preceding lobe.
