Perf Sealers has developed lightweight dissolvable ball sealers for operators to maximize their fluid diversion for completions. Using 0.9 specific gravity balls in vertical wells, most operators only need 10% to 20% excess to seal the perforations, verse 50% to 200% excess for the traditional 1.2 to 1.3 specific gravity balls.¹ By matching the ball sealers to the fluid density in horizontal wells, maximum efficiency can be achieved for all orientated perforations even if the pumps go down during the completion.² The lightweight ball sealers are available in specific gravity of 0.9, 1.0, and 1.1 and are rated for 3000 psi [20.7 MPa] differential pressure with excellent sealing properties.
