Case Study: Openhole Water Shutoff Solution Increases Oil Production

PROTECTOZONE, ZONELOCK, and SqueezeCRETE systems increase oil production by 3,000 bbl/d in Venezuela

Challenge: Shut off high-water production and increase oil production in gravel-packed completions in the South PetroBoscan field in Venezuela.

Solution: Treat wells using an innovative solution for water shutoff in gravel-packed completions by using a rigid aqueous gel system and a cement system designed specifically for squeeze cementing.

Result: Increased average oil production by more than 3,000 bbl/d. Reduced average water cut by 55%.
