Sweep patterns in delta sediments. (a) Preferential water ingress along channel sediments can result in bypassed oil in the surrounding sediments. From the South Pass Block 27 field, offshore Louisiana (from Hartman and Paynter, 1979). Reprinted with permission from, and © by, the Society of Petroleum Engineers. (b) Horizontal well drilled to target oil within a mouth bar in the Ivishak Formation, Prudhoe Bay field. Bay shales above the mouth bar act to prevent gas ingress from a gas cap immediately above (from Tye et al., 1999). Reprinted with permission from the AAPG. From Shepherd, M., 2009, Deltaic reservoirs, in M. Shepherd, Oil field production geology: AAPG Memoir 91, p. 279-288.
