Water Production data

Available water production data consisted of IP (initial production) records from Scout cards and annual barrel test results from 1989. The IP records show that measureable amounts of water were recorded in only 4 wells - Waugh #5, #6, #7, and Wharton #3. Of these 4 wells, water rates greater than 2 bbls/day were recorded in only 2 wells. It appears that initial water production from remaining wells were not significant enough to merit measurement and record.

Based on this limited water production data, it is not unreasonable to assume that initial water saturation in the reservoir was at “critical water saturation”, S_wcrit, where the relative permeability to water, K_rw,is effectively zero (or close to zero as perhaps is the case in this field).
