A first underground deposit of lignite or coal is heated by magnetic induction to recover hydrocarbon liquids and gases. The carbon remaining is combusted with air and steam to produce a gas which is combusted to generate electrical energy. The electrical energy is transmitted to second underground
A first underground deposit of lignite or coal is heated by magnetic induction to recover hydrocarbon liquids and gases. The carbon remaining is combusted with air and steam to produce a gas which is combusted to generate electrical energy. The electrical energy is transmitted to second underground deposits of oil shale, tar sand or heavy oil, and is used to heat the second deposits in order to recover hydrocarbon liquids and gases.
The method of producing hydrocarbon fluids from a part of one or more second underground deposits of hydrocarbons with a relatively small proportion of uncombined carbon, which comprises: injecting a conducting liquid into a first part of a first underground deposit of hydrocarbons with a substantia
The method of producing hydrocarbon fluids from a part of one or more second underground deposits of hydrocarbons with a relatively small proportion of uncombined carbon, which comprises: injecting a conducting liquid into a first part of a first underground deposit of hydrocarbons with a substantial proportion of uncombined carbon, and heating said first part of said first deposit by a varying magnetic field, under conditions of controlled pressure and temperature, and recovering substantially all fluid hydrocarbons present in and released from said first part of said deposit by said heating by said varying magnetic field, and injecting air and water into a second part of said first deposit from which substantially all hydrocarbon fluids have been previously recovered by the method of this claim, and combusting said air injected into said second part of said first deposit with substantially all of said uncombined carbon, in the presence of steam, so as to produce and deliver to the surface a combustible gas, and combusting said combustible gas with air to generate electricity, and using a first portion of said electricity to heat said first part of said first deposit by magnetic induction, and transmitting a second portion of said electricity to one or more of said second deposits of hydrocarbons, and using said second portion of said electricity to generate a varying magnetic field in at least a part of one of said second deposits of hydrocarbons, and injecting a conducting liquid into said part of said second deposits subjected to said varying magnetic field, and heating said part of said second deposits subjected to said varying magnetic field, under conditions of controlled pressure and temperature, and recovering at the earth\s surface said fluid hydrocarbons released by said magnetic heating of said part of said second deposits.
