Zusammenfassung: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. Método para detener o al menos reducir la liberación incontrolada de hidrocarburos, reventón, de un pozo de extracción de hidrocarburos, que comprende la introducción de sólidos de alta densidad en el fondo del pozo, a través de una línea adecuada, que tienen una forma poliédrica, esferoidal, elipsoidal o paraboloide, regular o irregular, posiblemente recubiertos con material polimérico hinchable en contacto con los fluidos que salen del pozo, siendo la dimensión más pequeña de dichos sólidos superior a 1 mm y la dimensión más grande de menos de 100 mm, de modo que dichos sólidos introducidos se acumulan al azar por empaquetamiento en el fondo del pozo, formando una columna que bloquea totalmente, o al menos parcialmente, la liberación incontrolada de dichos hidrocarburos.
