This paper documents the successful application of steamflooding in the multiple thin-sand reservoirs of the Loco Unit, Stephens County, OK. These reservoirs occur at depths from 50 to 1,200 ft (15 to 366 m) and range in thickness to 40 ft (12 m). Porosities of the productive zones vary from 20 to more than 30%, and permeabilities range from 100 to more than 4,000 md. Oil gravities of the various zones range from 16 to 24/sup 0/ API (0.96 to 0.91 g/cm/sup 3/). Reservoirs that occur at depths above approximately 700 ft (213 m) have little or no natural reservoir energy and generally contain viscous oils, ranging up to 10,000 cp (10 Pa X s). Consequently, there was no primary production from these reservoirs, and potential for waterflooding was marginal. Steamflooding has been the only recovery process applied successfully to these zones, except for one isolated instance. Reservoirs at depths greater than 700 ft (213 m) normally contain lower-viscosity oils. Six of these zones were produced by solution gas drive and were later waterflooded successfully. After 23 years of waterflooding, two of these six zones have been tested and have proved to support commercial steamflooding operations.
