Damon Mound salt dome, located in Brazoria County, Texas, is a shallow diaper that has salt less than 600 ft (180 m) and cap rock less than 100 ft (30 m) below the surface.
The Permian Spraberry Trend, once regarded as the world's largest uneconomic oil field, is a prime candidate for reserve growth through extended conventional recovery.
Subsidence at salt domes results from man-induced and natural removal of salt, cap rock, minerals within the cap rock, and supradomal fluids. In the Houston diaper province, Frasch sulfur mining as caused subsidence bowls and collapse sinkholes at 12 of the 14 sulfur productive domes.
More than 350 well logs and core and production data were used to geologically characterize oil reservoirs of the Driver waterflood unit of the Spraberry Trend in the Midland Basin, West Texas, and to assess the relationship between reservoir stratigraphy and oil recovery.
Cretaceous rocks in the Southern High Plains, traditionally considered to be part of the High Plains aquifer and recharged by the overlying Ogallala aquifer, actually contain three aquifers with different recharge sources.
