Dissolvable Perf Balls or BioBalls
BioBalls are small spheres or ball sealers designed to seal perforations that are accepting the most fluid, thereby diverting treatments to other portions of the target zone.
The field proven BioBalls temporarily seal perforations that are accepting the most fluid.
Applications
Plug open perforations for cleaning scale and paraffin. Improve stimulation by deveting fluid to lower-permeadility zones. Help manage fluid in hydraulic fracturing stages and refracs.
Features
Compatible with standard stimulation fluid additives. Dissolves in freshwater, brine, and acid. Differential pressure tested with fluid up to 4000 psi [27.6 Mpa] and 150 F [66 C].
Benefits
Will not stick in perforations like rubber coated ball sealers. Quickly dissolves in hours. Completely biodegradable material
