<br />The estimates by S,'enska Skifferolje are yer.v conserynt.ivE', since
<br />many of the larger deposits hnye been inadequately sUlTeyed. As
<br />more information becomes 1l,'niIable, the~e rese!'\'es will increase. For
<br />instnnce, U.S. reser\'es nlone now arc estimated at 1.5 trillion bnrrels,
<br />or about 200 billion metric tons (lH). It seems wit.hin reason that
<br />the world:s recoYl'rable shale-oil reser,'es may ult.inmtely pl'o\'e to be
<br />in excess of 500 billion metric tons, or O\'er 4, trillion lmrrels.
<br />For comparison, the table beJow"gives recent petroleum l'eser\'e est.i-
<br />mates for the United States and for the world as'a "hole.

<br />Hi~torical sketch
<br />
<br />Throughout 'the world, shale oil has been produced when petroleulll
<br />has been scarce or expensive. In fact, shale oil predntes the discovery
<br />of petroleum. and shale industries have operated in Europe for more
<br />than 100 years.
<br />For the past 50 years or so, owing to t.he abundance of low-cost
<br />petroleum~ shale oil has been relatively unimportant except in speeiaI
<br />circumstances. Howeser, during 'Vol'Id 'Val' II, shale oil supplied
<br />critically needed fuels for ,Japan, Sweden, Australia, and other coun-
<br />tries cut ofl:' from their normal source- of oil.
<br />Shale oil has ne\'er been of great import.ance in the United Stat.es,
<br />despit.p, our large reserves. Small quantities of oil were distilled from
<br />cannel coal and oil shale in the Appalachian region early in the history
<br />of our country, but shale oil has never been produee,l commercially
<br />from our western shales.
