The relationships between reservoir characteristics and flow regimes exhibited by twenty-one Uinta Basin gas wells represent fluvial, lake margin, and lacustrine deposits. Production data were analyzed to determine the type of flow for each well. This analysis indicated that one well exhibits radial flow, thirteen wells linear flow, and seven wells indeterminate flow regimes. Values of SSP, ..delta..t, R/sub w/ and SP curve patterns were determined from well logs. These data were compared for the three types of flow observed. It appears that SSP, R/sub w/ and SP pattern may be useful in qualitatively distinguishing between sands of low continuity and those with moderate continuity. The permeabilities are considerably higher than those normally attributed to ''tight sands.''Also permeability correlates inversely with the number of sands completed in each well. Consideration of the orientations of linear features in the area and those of reservoir lenses in outcrops indicates that the relationship between frac orientation and lens geometry cannot be effectively predicted without a good technique to predict lens orientation. Completion strategies to optimize frac efficiency are suggested, based upon the findings of this study.
