Method for hindering the non-authorized withdrawal of a liquid from at least one offtake conduit connected to a main conduit for the transport of the aforementioned liquid, in particular a mixture of hydrocarbons and water, the main conduit having an inlet port and at least one outlet port between which the liquid flows, the method comprising the step of: introducing a plurality of solid objects into the main conduit through the at least one inlet port, the plurality of introduced solid objects having weight, dimensions and density such as to be transportable towards the at least one outlet port by the main flow of the liquid and such as to be able to be possibly captured by the offtake flow of the liquid directed towards the offtake conduit, and such as to be able to possibly at least partially obstruct such an offtake conduit.

The present invention relates to equipment for the conveying and recovery of hydrocarbons from an underwater well for the extraction of hydrocarbons under uncontrolled release conditions, comprising a chamber () for the separation of the hydrocarbon stream leaving the well, into a heavy phase () and a light phase (), means () being envisaged, in connection with the separation chamber (), for conveying the heavy phase () and light phase () towards the surface, characterized in that it comprises a directioning body () of the hydrocarbon stream, having a substantially cylindrical shape, or as a truncated paraboloid with both ends open, wherein a first end is an inlet of the hydrocarbon stream leaving the well, and a second end, distal with respect to the inlet of the hydrocarbon stream (), is in fluid connection with the separation chamber () with the interpositioning of a perforated spherical cap ().

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.
