WebModern ooid shoals on the Bahamian Platform • Modern (active) ooid shoals – Lobate shoals form complex geometries shaped by hydro-geomorphic controls – Internal bedding and granulometrics (sorting and % mud) are predictable – (Temporally-distinct) geometries and bedforms appear to be in dynamic equilibrium with local setting. The Haynesville Shale came into prominence in 2008 as a major producer of shale gas in East Texas and Louisiana. Producing natural gas from the Haynesville Shale involves drilling wells from 10,000 feet (3,000 m) and to 13,000 feet (4,000 m) deep; the formation becomes deeper to the south.
