The Granville pay zone produces oil and gas from pelecypod/ gastropod rudstone and grainstone carbonate sediment-piles that accumulated as shoal and beach deposits on a shallow-water carbonate platform in Late Ordovician (Edenian) time. Fresh-water vadose diagenesis produced secondary porosity into which hydrocarbons migrated. There is a predictable trend to these Granville pay zone reservoirs, and other similar reservoirs can be predicted using modern sedimentological techniques.
