In situ shale oil recovery from oil shale deposits using radio frequency energy as a heat generator is facilitated by rubblizing the shale oil deposits before application of radio frequency energy.
In a process for recovering hydrocabonaceous material from a solid non-freeflowing hydrocarbonaceous material bed in which said bed is heated in situ by applying radio frequency energy thereto to effect dielectric heating of said bed, the improvement wherein said bed is rubblized prior to the applic
In a process for recovering hydrocabonaceous material from a solid non-freeflowing hydrocarbonaceous material bed in which said bed is heated in situ by applying radio frequency energy thereto to effect dielectric heating of said bed, the improvement wherein said bed is rubblized prior to the application of radio frequency energy thereto, said radio frequency energy being applied by means of conductors inserted into said bed prior to rubblization. A system for in situ heat processing of hydrocarbonaceous earth formations comprising: conductive means inserted in said formation and electrically bounding a particular bed of said formation on at least two sides thereof; electrical excitation means for establishing alternating electric fields in said bed, the frequency of said excitation means being selected as the function of the bed dimensions so as to establish substantially non-radiating electric fields which are substantially confined in said bed whereby volumetric dielectric heating of the formations will occur to effect approximately uniform heating of said bed; and means for rubblizing said bed in situ.
