Waveland field: analyses of facies, diagenesis, and hydrodynamics in Mooringsport reservoirs

Journal Article · · Oil Gas J.; (United States)
OSTI ID:6836220
Waveland field on the Mississippi Gulf Coast could hold recoverable reserves of 0.5 trillion CF of gas and 10 million bbl of condensate. The field's 36 wells have produced as much as 125 million CF and 2800 bbl per day, primarily from the Mooringsport formation. The Mooringsport reservoirs are backreef and lagoonal deposits of porous orbitolinid- and miliolid-lime packstones and grainstones, interbedded with tight, but fractured, pellet and mollusk-lime mudstones. Petrographic studies indicate that only the orbitolinid beds produce hydrocarbons, as explained by the significantly different relative gas/water permeability between the two porous facies. This behavior is apparently the product of varying styles of diagenesis (recrystallization vs. leaching). Fracture studies indicate that the relative permeability phenomenon persists in a vertical sense, between layers. As a result, hydrocarbons within the reservoir are effectively influenced by the high concentration of connate water.
