Gel Systems Improved Oil Production in Old Fractured Carbonate Well Results • Increased oil production from 9 to 31 BOPD • Payout for treatment within weeks • Reduced water production from 2,200 to 235 BWPD • Reduced operating cost Challenges • Low oil production and excessive water production at uneconomic levels (9 BOPD/2,200 BWPD) • Older, openhole producing well • Naturally fractured formation with underlying aquifers BHGE solution • Customized treatment using BHGE gel systems penetrated formation • Avoided mechanical isolation during treatment • Well was placed back on production within days • Production optimization was immediate An openhole producer in the Ellenburger formation in Reagan County, Texas, had reached uneconomic levels, producing 9 BOPD/2
