Looking for a BioBalls® Alternative?
BioBalls® water-soluble ball sealers from Covia are an established, field-proven diverting agent for oil and gas hydraulic fracturing and acidizing. If you are evaluating BioBalls — or sourcing a replacement supplier — Perf Sealers manufactures a full line of dissolvable and Rubber Coated Nylon (RCN) ball sealers, also called perf balls, built for the same job: temporarily sealing perforations to divert treatment across the target zone.
