The volume of investigation and sampling interval of each petrophysical tool and how each relates to geologic scales are critical to data analysis and permeability prediction. These issues are examined in the context of the As Sarah Field, Sirte Basin, Libya. The small scale permeability variability was better predicted using a flushed zone resistivity (Rxo) tool. For the larger scale, the production flowmeter highlighted discrepancies between flow data and averaged permeability, yielding a layered sedimentological model interpretation and a change in averaging for permeability prediction.
