East Texas Smackover Study

East Texas / Northen Louisiana / Southern Arkansas

GEOLOGIC STUDY AND RESERVOIR EVALUATION OF THE EAST TEXAS BASIN SMACKOVER FORMATION

Core Laboratories is offering for resale a completed study of Jurassic Smackover Formation strata in east Texas. The study area includes Rains, Limestone, Van Zandt, Freestone, Henderson and Wood Counties with sixteen (16) conventionally cored wells.

The objectives of this study are to:

• Describe and sedimentologically analyze the cored intervals, leading to the development of depositional models, with emphasis placed on improved delineation of Smackover reservoirs.
• Identify porous zones, pore types, pore system properties, and diagenetic alterations that affect reservoir potential.
• Determine the petrophysical properties of reservoir rocks for improved formation evaluation.

These objectives were met through a combination of detailed core description, thin section petrography, special core analysis (resistivity measurements and air-mercury injection capillary pressure tests), scanning electron microscopy, and through the construction of combined facies/diagenetic cross sections. Observations and conclusions derived from the analyses of these wells are provided in a five- volume final report that synthesizes and integrates the geological and petrophysical data as well being presented in individual well reports.
