Silica gel as a viscosifier for subterranean fluid system |
abstract |
This invention relates to a composition and method of fracturing subterranean formations utilizing a polymerized alkali silicate. The fracturing fluid includes an alkali silicate such as sodium silicate and an acid such as hydrochloric acid. The sodium silicate is polymerized to a silica gel using an acid. The resulting silica gel has a pH from about 2 to less than 7.5. |
