The undiscovered recoverable oil, reported at the 95- and 5-percent probability
levels, for the Wilderness Lands in the Western States is estimated to range from
0.555 to 1 .490 billion barrels with a mean estimate of 0.834 billion barrels.

One measure of system efficiency is the ratio of heat recovered to heat injected,
which can be expressed as a percentage. The higher the percentage, the more
efficient the ates system. Preliminary model simulations indicate that, under the ...
