ABSTRACT
Data (scout tickets, wireline logs, and core samples) from about 375 wells were analyzed in this study of the past and future potential for increased oil recovery from the Aux Vases Formation at New Harmony Field in White County, Illinois.

INTRODUCTION
Bordering Indiana, the New Harmony Field is an elongate oil field running North- South in the northeast corner of White County at the eastern limit of oil production in the Mississippian Aux Vases Formation (fig. 1). The roughly 27,000 acre field produces mainly from the Cypress, Bethel, and Aux Vases Formations, lying at depths from 2,500 to 2,900 feet. The Aux Vases traps are formed by stratigraphic pinchouts of reservoir sandstone bodies across a long anticlinal nose. New Harmony...
