Abstract:
1. A variable viscosity high carrying capacity temperature-stable breakable gel with high-temperature stability for use as a lubricant and carrier of solids, particulate matter, semi-solids, proppants, and liquids into subterranean well formations, comprising: a first or base concentrate comprising: a second or activator solution containing a mixture of water, an amine cross-linking agent, and a nonionic surfactant; said first or base concentrate and said second or activator solution being mixed together in a ratio of from about 93% to about 99.95% by weight of said first or base concentrate to about 0.05% to about 7% by weight of said second or activator solution to raise the pH of said first or base solution and instantaneously trigger formation of a high carrying capacity temperature-stable breakable gel having high-temperature stability and lubricating characteristics and a viscosity sufficient to support, suspend, and carry solids, particulate matter, semi-solids, proppants, and liquids therein into subterranean a well formation during drilling, fracturing, completion and production operations.
