Near Wellbore Diversion

Div+ NWB products are temporary diverting materials used to increase cluster efficiency and/or reduce stage count in fracturing treatments. During placement, DiverterPlus is a solid non-toxic polymer capable of blocking perforation tunnels and fractures near the wellbore. After the product’s designed service life, the diverter will hydrolyze into a clear, non-hazardous liquid. This process is driven simply by time, temperature and pressure in the presence of water meaning that no additional remedial work is necessary. DiverterPlus blends are unique multi-modal blends of particles for optimized transport and plugging performance.

Ideal pressure response indicating proper near wellbore fracture diversion shows new breakdown pressure increase, an offset in pressure, and a change in slope of post-drop frac pressure.

DiverterPlus specializes in tailoring the diversion package to your specific treatment and well conditions. By selecting from our versatile product portfolio and customizing deployment design, DiverterPlus consistently delivers optimal diversion results. Our customers can rely on our experience and expertise as we work hand-in-hand to optimize cluster efficiency and stimulation treatment distribution across the desired interval. In non-homogenous reservoirs, this can greatly increase stimulated reservoir volume. In relatively homogenous reservoirs, cluster efficiency can be increased to the point where multiple stages can be combined resulting in fewer plugs/stages, decreasing completion time and saving operators money.

Improperly designed diverter treatments (top) result in uneven particle distribution resulting in perforation phase dependent diversion. Proper diverter design (bottom) provides efficient diversion regardless of perforation design.
