2018042 USING ENGINEERED DIVERSION STRATEGIES TO EFFECTIVELY STIMULATE NEW ROCK

This paper will present a methodology being applied which examines well heterogeneity, and designs the diversion strategy based on actual reservoir properties.  Estimations of minimum insitu stress at each cluster are combined with estimates of stress shadow effect both from previous stages and between treatment clusters, to determine at which pressure each cluster will accept fluid.  This data is then used to bin clusters into the ones which will be treated first, followed by a diverter slug, then second and potentially third.  The volume of diverter slug used will be proportional to the number of clusters within the previous bin.

In addition to this, an engineered diversion strategy will look at the perforation design, fracture treatment design and pump rate. The result of this workflow is a tool that will maximize the effectiveness of diverters which ultimately will result in better producing wells at lower completions cost.   This paper will also present case studies of this technique showing validation of it’s success.
