• i-Frac OHS

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