i-Frac CEM™
i-Frac CEM™ is a ball drop activated multistage frac system for cemented horizontal completions. The system is installed as an integrated part of the lower completion string. Multiple stages can be installed in a wellbore, and each stage can contain between 1 to 20 sliding sleeves for optimized fracture design. Once installed, the system is cemented in place as a normal casing string and a wiper dart is pumped from surface to ensure that the pipe ID (inside diameter) and ball seats are wiped free of cement. For each stage, one ball is pumped from surface to open all sleeves in the given stage. The frac job can then be carried out in a continuous pumping operation with no prep time between stages.

Features
◾Ball drop operated.
◾Designed for cemented applications.
◾Configurable nozzles and shear pressures.
◾1/6 in., 1/8 in., 1/10 in., 1/12 in. and 1/16 in. seat increments.
◾Between 1 to 20 sleeves per stage.
◾No explosives required on location.
◾Drillable cast iron ball seats for easy mill out.
◾Proven field success across all major plays.
◾Compatible with dissolvable frac ball technology – frac balls that degrade over a calculated time period in the presence of temperature and fluid, allowing production operations to begin with no well intervention.
◾Max number of stages: ◦21 stages for 4.5 in.
◦29 stages for 5.5 in.

Benefits
