The Sorrento field is in southeastern Colorado on the north flank of the Las Animas Arch. The map in Figure 1 shows the location of the Sorrento field. Structure is contoured on the base of the Pennsylvanian.

The Sorrento field reservoir is Pennsylvanian Morrow valley-fill sandstones. As shown in the figure below, structure contours on a marker bed above the Morrow Sandstone reflect the irregular thickness of the sandstone body and a small structural nose and closure. The oil column is length::70 ft depth::(20 m) and exceeds structural closure. This is a combination structural-stratigraphic trap. Fluvial sandstones lap onto marine shale at the margins of the valley, forming lateral seals.
In Figure 2, circled wells represent Marmaton wells; triangles, Mississippian wells; and large X's, study wells. The rest of the oil wells produce from the Morrow. Each unit in the grid is 1 sq mi.
