System and method for permanent plugging of a petroleum well

A system for plugging a petroleum well with a fluid plugging material, wherein the system comprises:

• a valve for a landing packer adapted for forming a bridge plug in the petroleum well, the landing packer provided with a passage between an upper face and a lower face, the valve adapted to close the passage, and
• a tool adapted for displacement in the petroleum well, wherein:
• the tool comprises a leading end;
• the tool comprises an internal compartment adapted to house and release the fluid plugging material;
• the valve comprises a biased valve body adapted to be displaced between a first position and a second position;
• wherein in the first position, the valve body closes liquid tight an entrance to the passage, and in the second position, the entrance is open;
• the valve body is adapted to receive the tool from above;
• the valve body is adapted to be displaced from the first position to the second position by a downward force executed by the tool;
• the valve body is adapted to be displaced to the first position when the downward force executed by the tool is removed;
• and
• the tool is adapted to abut fluid tightly the biased valve body, and to displace the biased valve body between a first closed position and a second open position by the downward force executed by the tool.
