ABSTRACT

The Upper Jurassic Haynesville Formation in Teague Townsite Field, Freestone County, Texas, consists of grainy limestones, muddy limestones, shales, and quartz conglomerates. Constituent grains in the limestones are primarily non-skeletal with ooids being the most common grain type.

Composition and textural data from petrographic studies were grouped into seven microfacies. These microfacies represent three depositional environments: (1) tidal bar, (2) open marine, and (3) restricted marine. The distribution of these environments was controlled by contemporaneous salt movement.

A major shoaling upwards sequence is present in the Haynesville Formation. Nine smaller, local cycles are also present; these local cycles were probably caused by intermittent salt movement during deposition.

Four major diagenetic environments are recognized: (1) marine phreatic, (2) mixed or brackish phreatic, (3) meteoric phreatic, and (4) subsurface environments. Dissolution of ooids in the meteoric phreatic environment created very fine, intragranular porosity in oolite grainstones. Leached zones occur at the crests of the upper shoaling cycles. Virtually all intergranular porosity has been filled by subsurface coarse, mosaic spar cement. Production is from the intragranular porosity created by early meteoric leaching.
