ABSTRACT
This paper presents the results of an investigation of the comparative effectiveness of various fracture propping agents and their relationship to production performance based on actual field results of twenty-five wells producing from the same formation at approximately the same depth and similar downhole reservoir conditions. All are located in thirteen fields of the Anadarko Basin in Roger Mills and Beckham Counties, Oklahoma (Fig. 1). Every Red Fork well listed in the records of the Oklahoma Corporation Commission for these counties which had been fractured and treated with a propping agent was examined. All wells for which valid production information was available are included. Three of a total of 28 wells were eliminated because of ambiguous data.

A comparison is made of the actual production of wells measured before and after hydraulic fracture stimulation treatments that employed one or more of the various propping agents; sand, glass beads, resin coated sand, or sintered bauxite. The size and type of treatment varied from well to well.
The relation between actual field results and laboratory tests under simulated field conditions is reviewed for the several types of proppants.
