The Drill2Frac Engineered Diverter Solution estimates the stresses along the lateral. By knowing the stresses at each cluster, we can determine which clusters will break down and take fluid first, then design the completion in such a way that only those clusters take fluid initially, and that the secondary clusters do not break down during the initial pumping segment. Also, by knowing how many clusters will initially take fluid, we can determine how much diverter to use. Then we determine which clusters are likely to take fluid next and design for that.
To ensure that clusters are properly segregated into distinct pump segments, we use a multi-faceted approach which is grounded on a stage-by-stage pressure balance. This pressure balance ensures that clusters are only broken down and treated according to the design. This is done using multiple approaches including placing clusters in opposing stressed rocks, adjusting perforation design, adjusting pump rates, and inducing intrastage stress shadows.
