1. A method of continuously thermally treating an oil reservoir comprising the steps of:

  • initiating a chemical reaction producing heat and gases for thermally treating the oil reservoir to obtain extractable oil or an extractable oil containing mixture by separately introducing into an oil well of said oil reservoir a first and a second composition through separated fluid passages provided in said oil well and contacting the first and second compositions in the pay zone of the oil reservoir;

    maintaining the chemical reaction in the oil reservoir by continuing the introduction of at least one of said first and second compositions; and

    extracting the resultant oil or oil containing mixture during said step of maintaining the chemical reaction through a fluid passage provided in said oil well, wherein inside said oil well the fluid passage used for extracting the oil or oil containing mixture has no fluid connection with any fluid passage used for continuing the introduction of at least one of said first and second compositions to maintain the chemical reaction.
