  • Process employing CO.sub.2 /CH gas mixtures for secondary exploitation of oil reservoirs
    Patent number: 4628999
    Abstract: From 5 to 35%, preferably 10 to 30%, by volume of hydrocarbon gases may be incorporated as a diluent into carbon dioxide-containing gas injected during secondary exploitation of oil reservoirs. The reservoir pressure is maintained at 100 to 120 atm., respectively, up to 250 atm. The preferred range is 120 to 200 atm. The hydrocarbon gases may be added to the carbon dioxide-containing gas prior to injection and/or use may be made of ambient hydrocarbon gases present in the reservoir. The optimum gas injection rate is 40-80 m.sup.3 /day/m of formation.

  • Process for the recovery of shale oil, heavy oil, kerogen or tar from their natural sources
    Patent number: 4419214
    Abstract: A method of recovering hydrocarbon substances such as oil and tar from naturally occurring mineral matter such as oil shale and young coal ranks, which comprises subjecting the natural mineral product to microwave irradiation in a pressure vessel through which an expelling medium is passed. The expelling medium can be gaseous or liquefied carbon dioxide containing natural or mixed gases, hydrocarbon-containing gas, vapor or liquid and gaseous or vapor-halogenated hydrocarbons.
