FRACSAL OS

1 of 13 products in this brand
Fracsal OS is a concentrated borate solution that is used to crosslink guar and derivatized guar-based fracture fluid systems. Fracsal OS is able to achieve low pour points by incorporating a pour point depressant that exhibits low toxicityand has excellent biodegradability. Fracsal OS solutions can achieve pour points as low as -46°C (-15°F). Required pour points for Fracsal OS may be tailored to meet specific customer requirements. This product is added continously during the fracturing fluid pumping operation. Fracsal OS produces a unique gel structure downhole that is elastic and thermally stable. This product exhibits improved sand transport into fractures, and the ability to re-heal itself and form a stable gel structure after shearing.
