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