The answer is; Oil shale occurs only in areas with plentiful water resources for processing.

The refinement of oil shale requires a lot of water. This is used to quench the products of retorting and pyrolysis and also reduce dust. The water used becomes heavily polluted and has to be treated before discharge, otherwise, it will be the cause of a major environmental disaster to the local areas.
