Abstract
This invention provides novel highly acidic gels of polygalactomannan allyl ether gum and sulfur dioxide. The gels exhibit dimensional stability, and are useful for oil well acidizing and borehole plugging, and for the preparation of explosive slurries.
Claims6
A gel composition consisting essentially of water, between about 0.05 and 2 weight percent sulfur dioxide, and between about 0.25 and 5 weight percent polygalactomannan allyl ether gum having a degree of substitution between about 0.01 and 3.0.
A process for preparing a gel of polygalactomannan allyl ether gum which comprises introducing sulfur dioxide into an aqueous solution of between about 0.25 and 5 weight percent polygalactomannan allyl ether gum having a degree of substitution between about 0.01 and 3.0 in sufficient quantity to increase the viscosity of the aqueous solution to gel formation.
