But these lake-bed accumulations were never subjected to temperatures as high as 300° F and to extreme pressures that in time created underground deposits of readily usable liquid oil and natural gas. Now man must finish nature...

Colony uses a different process: it cooks finely ground shale in giant drums by mixing the marl with superheated, marble-size ceramic balls that distribute the temperature evenly and vaporize the kerogen. The balls are then separated from the spent shale by a screen, reheated and used again...
