Abstract
A process for the geoconversion of coal into oil comprising the steps of forming a coal slurry, injecting the coal slurry into a preselected oil well to provide an environment for the coal slurry having predetermined pressure conditions of approximately 1500 to 4500 lbs./in..sup.2 and temperature conditions of approximately 200.degree. to 300.degree. F., converting the coal into oil as a result of the combined action of the heat and pressure upon the coal, and removing the resulting oil after sufficient time has elapsed for conversion of the coal into oil.
Claims8
A process for the geoconversion of coal into oil, comprising the steps of:
- forming a coal slurry of coal and crude oil in which the percentage of coal in the coal slurry is in the range of about 60% to about 80%;
- injecting the coal slurry into a preexisting oil well having a depth of about 10,000 to about 20,000 feet below the earth's surface to provide a geoconversion environment for the coal slurry having predetermined pressure conditions of approximately 1,500 lbs./in..sup.2 to 4,500 lbs./in..sup.2 and temperature conditions of approximately 200.degree. to approximately 300.degree. F.;
- converting the coal into oil as a result of the combined action of the heat and pressure upon the coal;
- and
- removing the resulting oil after sufficient time has elapsed for conversion of the coal into oil.
