Ball-Activated Frac Sleeve
Ball-Activated Frac Sleeve is designed to provide access of fracturing fluid and proppant gel into the appropriate open hole isolation zone.The system maintains the operational simplicity, time and cost savings of ball drop methods.
- Ability of opening settings manipulation
- Protection from mill jamming
- 100% successful couplings opening during the entire period of operation
Ball-actuated device. Available various types of balls for certain conditions: acid fracturing, with low specific weight, soluble balls.
Frac Dissolving Balls.
Dissolvable Frac Ball can be used in ball activated sleeves. While reaching the sleeve saddle during pumping of fracturing fluid, ball overlaps liner passage area that allows for creating excess pressure for Frac Sleeve ports opening. The balls are available in different sizes.
