ABSTRACT Method of regaining control over an abandoned well in the sea bottom, after it has erupted and is spilling hydrocarbon fluids into the sea water, by positioning directly above the well an emergency well- control vessel (30) having a fire-extinguishing-gas- dispelling system (60) and well-killing equipment (29), operating the system to prevent the ignition of the hydrocarbon fluids which reach the vessel, and lowering the equipment into the well to therewith control the well. Preferably, the system includes blowers (32) and propellers (31), and the equipment includes a kill string (40) which is lowered into the well. A weighted fluid is circulated down the kill string and up through the annulus of the well, whereby the fluid pressures in the wellbore are overcome by the greater hydrostatic pressure exerted by the circulating fluid, thus allowing the equip- ment to gain control of the well. In use, the well has a wellhead (12) carrying a stack of blowout preventers (11). Divers (37) connect the stack of blowout preventers to control lines (34) on the vessel. Then the preventers are operated to seal around the kill string before circulating the weighted fluid. The kill string preferably includes a packer (44) which can be operated to packoff against the well casing (8).
