[[:file:sedimentary-basin-analysis_fig4-58.png|Figure 1]] contrasts the depositional setting of the ''Trim A'' (A) and ''Glob alt'' (B) sandstones of the East Breaks 160-161 field. Drilling at the field encountered only channels in the ''Trim A'' reservoir, with the channel-fed lobes interpreted to occur further down paleoslope in the age-equivalent hummocky-mounded-to-sheet seismic facies. The ''Trim A'' shelf edge is mapped at the north boundary of the field. Thus, all ''Trim A'' associated sandprone facies are restricted to this minibasin. Drilled ''Glob alt'' facies include channels and channel-fed lobes nearly [[length::50 mi]] (80 km) from the mapped ''Glob alt'' shelf edge and probable deltaic sediment source from which the gravity-flow sands were supplied. Exploration potential within the ''Glob alt'' depositional sequence exists along the entire sediment transport system, as clearly demonstrated by the known occurrence of ''Glob alt'' reservoirs in the High Island-East Breaks area ([[:file:sedimentary-basin-analysis_fig4-40.png|Figure A]]).
