Demartino, R N; Conciatori, A B

Natural gum derivatives are provided having viscosity and suspending properties for application as gelling agents in hydraulic well-treating fluid compositions. Hydraulic well-treating fluid compositions are described containing a natural gum derivative in combination with breaker additive, as well as hydraulic well-fracturing fluid compositions containing a polygalactomannan ether derivative in combination with an enzyme as a breaker additive, which are characterized by a low yield of hydrolysis residue. Also provided is an ether adduct derivative of polygalactomannan gum which has superior properties for application as a dispersing agent or a textile print gum. 6 claims.
