As the shortage of energy increased, the extraction of oil shale resources got attention. Method of retorting was not applicable for oil shale resources in Jilin. To create a new method for in-situ oil shale mining was very necessary. The method of high voltage with power frequency electric heating in-situ pyrolysis of oil shale was proved to be feasible, which could generate the oil, gas and should be deeply studied. The production test result was complex, and the product showed the kerogen pyrolysis at this condition.
