Approximately 60 Piocene and Miocene deltaic and turbidite pay sandstones range in depth from 1000 to 6000 m. Horizontal wells focused on seven late Miocene deltaic and shore-face sandstones ([[:file:Mth14ch04f06.jpg|Figure 6]]). Typically, these sandstones were fine grained, well sorted, uncemented, and normally pressured.

Typically, these sandstones were fine grained, well sorted, uncemented, and normally pressured.

Upper-shoreface sandstones (e.g., M4) typically were 3 to 6 m thick, continuous, upward coarsening, well connected, and easy to correlate. Horizontal wells in these reservoirs were the program's most productive and profitable (C11 and D32). Excellent connectivity and continuity resulted in high rates and good drainage.
