Non-Toxic Gas Recovery Carboxymethyl Guar Gum Used In Hydraulic Fracturing
Quick Detail:
1. Carboxymethyl guar gum is an anionic carboxymethyl guar modified from guar gum.
2. Carboxymethyl guar is used as a fracturing fluid in the recovery of oil and gas.
Description:
1. Viscosity build over time is dependent on pH, shear rates, and temperature.
2. Carboxymethyl guar is a self-hydrating polymer; therefore, no external buffer systems
are required to control viscosity development. This polymer is self-hydrating and yields a pH
of 5-6 in 2% KCl water. It exhibits very good hydration in cold water (40° F) as well as warmer
water (80° F or higher) and is somewhat sensitive to alcohols and monovalent salts.
Applications:
1. When crosslinking the carboxyl group, an aluminum complexing agent is recommended.
It exhibits excellent carrying capacity to support sand or other proppants to be placed in
the fractured area.
2. Put Carboxymethyl guar gum into the water with rapid agitation, adding at the point of
greatest agitation. Viscosity will develop without adjusting solution Ph value.
