The primary purpose of this study was delineate trends of high reservoir quality and define the petrographic controls of reservoir quality. Additional objectives include the identification of pay and non-pay zones of interest. The documentation of diagenetic minerals, their effect on reservoir quality, and their geographic and stratigraphic distribution are also discussed.
A total of 200 samples from forty-eight (48) wells representing both upper and lower Stevens sandstones were analyzed. Interpretation of reservoir quality, controls on reservoir quality, and areas favorable for exploration are provided in this study. Recommendations concerning precautions for drilling, completion, and enhanced recovery methods as well as wireline-log analysis are also provided.
