Devices, materials, and compositions of diverting material, and related methods and systems for making same and using same to divert a fluid in an underground formation such as a wellbore. The diverter devices, material, and compositions may be manufactured by various methods, including 3-D printing using a variety of polymers.
Disclosed herein are compositions, processes, and systems for deploying and creating a temporary fluid barrier at an interface between a high fluid conductivity zone and a lower fluid conductivity zone. The disclosed compositions include mixtures of solvents and biodegradable non-spherical particles, wherein the particles include a coating that may slow or inhibit degradation, for example by hydrolysis, of the particle. The disclosed particles are designed to possess sufficient flexibility to traverse the high conductivity zone.

CONTROLLING WELLBORE PATHWAYS BY MANIPULATING THE SURFACE AREA TO MASS RATIO OF THE DIVERTING MATERIAL
The present invention relates to a mixture of various shapes of a dissolvable diverter material. Generally the shapes range from a flake having a very high surface area to mass ratio the beads having a low surface area to mass ratio. However the density of the various shapes may be manipulated by including voids or low-density materials within the shape. The density manipulation is desirable in order to match the transport properties of the various shapes to the transport fluid so that both shapes may arrive at the desired location at the desired time.
