Abstract
Method for stopping or at least reducing the uncontrolled release of hydrocarbons, blowout, from a well for the extraction of hydrocarbons, which comprises introducing high-density solids at the bottom of the well, through a suitable line, having a polyhedral, spheroidal, ellipsoidal or paraboloidal form, regular or irregular, possibly coated with swelling polymeric material in contact with the fluids leaving the well, the smallest dimension of said solids being greater than 1 mm and the largest dimension less than 100 mm, so that said solids introduced accumulate by random packing at the bottom of the well, forming a column which totally, or at least partially, blocks the uncontrolled release of said hydrocarbons.
