Get fast, effective isolation, without permanently blocking your producing zones, with the GelBlock™ temporary annular isolation system from Baker Hughes. The temporary guar-based gel blocks previously stimulated zones, allowing you to re-perforate and re-stimulate newer, productive zones. The GelBlock system can then be dissolved quickly and completely, a benefit in regions where strict environmental regulations apply. The treatment leaves your formation virtually damage-free while effectively opening up all available hydrocarbon flow paths. With the GelBlock system, you can quickly reverse production decline rates and maximize your recovery factors, all without the high operational and CAPEX spend of drilling a new well.
