A well tool device for forming a permanent well barrier includes a housing having a circular cross-section and a longitudinal extension; a pyrotechnic mixture provided in the housing; a flow generating device provided in the housing; and a motor for driving the flow generating device. After ignition, the pyrotechnic mixture turns into a molten mass; and the flow generating device is configured to generate a forced flow of the molten mass. A method for forming a permanent well barrier using the well tool device includes installing the well tool device in a well; and igniting the pyrotechnic mixture. The pyrotechnic mixture turns into a molten mass upon ignition. The method further includes starting the motor; and generating a forced flow of molten mass by the flow generating device.

Well tool device and method of forming a permanent well barrier, configured to generate a forced flow of molten mass

A system and a method of an ignitor for electrical ignition of an exothermic mixture to be used in wells, for the purposes of reinstatement of a barrier in well(s), subterranean storage reservoirs for a variety of potential environmental damaging materials such as CO2, radioactive storage, and other uses. Additionally, the ignitor may include a housing with a compartment within the housing, a first exothermic mixture of at least a metal and an oxide provided in the compartment, a first electrode connectable to a first terminal of a power supply, and a second electrode connectable to a second terminal of the power supply.

Ignitor, system and method of electrical ignition of exothermic mixture

Method and use of abandoning a well () or removing a well element () which is arranged in a well () by melting surrounding materials or by melting the well element (), the method comprising the steps of; providing an amount of a heat generating mixture (), the amount () being adapted to perform one of the desired operations, positioning the heat generating mixture () at a melting position in the well (), igniting the heat generating mixture (), thereby melting the surrounding materials in the well () or melting the well element ().
