The Upper Wolfcamp and Third Bone Spring Sandstone, both highly prolific reservoirs in the Delaware Basin, are compositionally complex sediment gravity-flow deposits. Observations from core show a highly heterogeneous strata with variations in bed thickness, lithology, and sedimentary structures. This study will explore the lithofacies observed in core and the implications on reservoir character, source potential, and target zone selection. Careful examination of spatial and temporal trends allows for correlation to outcrop derived stratigraphic framework.
A broad range of bed types are observed from sandy mass transport complexes, hybrid event beds, organic-rich fine-grained turbidites and shale couplets, and platform-derived course debris flows. The interaction of these beds makes for a complicated petroleum system where each bed type varies in source rock or reservoir rock quality. While development planning, a range of concepts emerges. Tested targets include stacked reservoir facies, stacked source rock facies, and coupled source rock and reservoir facies.
