the Ferry Lake Anhydrite in the Mooringsport field area of Caddo Parish, Louisiana. In
the Union Producing Company's Noel Estate well No. 1-A, the Mooringsport occurs at a
depth of 3,565 ft (Forgotson, 1957). McNamee (1969) included the Mooringsport and
Upper Glen Rose formations as part of the Glen Rose Reef Complex in Texas and
Louisiana. The Mooringsport (Rusk equivalent of Texas) has been extended into
Mississippi. Adams (1985) placed the Mooringsport in the upper section of the Glen Rose
Subgroup. He described six depositional environments in the Mooringsport, including
basin, forereef, reef, bank margin, bank interior and restricted shelf. Adams (1985)
reported that relatively rapid subsidence/sea level rise is responsible for the vertical
growth of the Mooringsport reef complex of up to 1,600 ft thick.
In the areas where the Mooringsport produces in northern Louisiana, the depth to top
of pay ranges from 3,000 to 5,000 ft with net pays of 10 to 30 ft. Porosity of 10 to 20%
and permeability of 10 to 500 md are common. According to Baria (1981), in the deeper
reservoirs (13,400 ft) in some areas of Waveland field, Mississippi, porosity and
permeability are both related to primary intergranular and intraparticulate pore space in
shoal or shallow bank deposits. In this field, porosity varies from 10 to 17%, and
permeability averages about 7 md. In these reservoirs, fractures are an important factor
controlling the prolonged and prolific production at Waveland field. The produced
hydrocarbons are primarily gas and condensate.
