This paper introduces a new coil tubing deployed system which uses Hydrajet Assisted Fracturing (HJAF) technology to lower treatment pressures and optimize fracture extension in the zone of interest. This process offers a low-risk, operationally flexible, and efficient multi-stage stimulation method designed to reduce the time between stages and minimize the total fluid pumped into the reservoir. Also included is a detailed case history in the Spearfish that demonstrates how this process can maximize return on investment (ROI) for the operator.
