Abstract
Compositions useful as wellbore fluids are generally disclosed. In some embodiments, the compositions include polymerizable olefinic surfactant compositions, which, under certain conditions, can polymerize via free-radical polymerization to form surfactant polymers. In some embodiments, the compositions are introduced to an oil well as part of the drilling or extraction process, e.g., to assist in flushing hydrocarbon material out of subterranean formations.
