Since discovery in September 1983, nearly 200 wells have extended Alabama Ferry field to a surface area of approximately 70 mi/sup 2/. Located primarily in southeastern Leon County, east Texas, Alabama Ferry is oil productive from stratigraphically trapped carbonate reservoirs in the Lower Cretaceous upper Glen Rose D interval. Deposition within the field was the end result of a very large tidal-dominated system most likely initiated at a break along the upper Glen Rose shelf margin. Progradation of the tidal system lagoonward during D time resulted in the deposition of five separate, vertically stacked, shoaling-upward flood tidal delta sequences (subintervals). Environmental interpretations were based on four subinterval characteristics delineated from core descriptions and detailed mapping. Porosity distribution in the field area is primarily facies related. Oolitic-dominated marginal and mud-rich lagoonal facies have low prosities, intraclast-dominated channel facies have low to moderate porosities, and skeletal-dominated inner fringe facies have moderate to high porosity values.
