Description
The i-Frac™ OHS is a ball-drop-activated multistage fracturing sleeve specifically designed for openhole conditions. For each ball pumped from surface, a corresponding sleeve downhole is opened, allowing communication between the casing inside diameter (ID) and the formation of interest. The stimulation operation is continuous, with balls of increasing outside diameter (OD) being pumped from surface as the operation works towards the heel of the wellbore.
