Abstract
Gas blowouts in wells are controlled by injecting a cohesive aqueous gel composition of hydroxypropyl guar gum, a borate salt cross-linking agent and a weighting agent such as silica flour, barite, hematite or iron oxide. The kill fluid is less susceptible to atomization than weighted drilling fluids, is readily available in most oil and gas field operations and may be rapidly prepared in quantities suitable for injecting into a well to control a gas blowout.
