The reserves, or extractable fraction, of the fuel-mineral
endowment are sufficient to supply the bulk of the world's energy
requirements for the immediately forseeable future-well into the
next century according to even the most pessimistic predictions.
But increasingly sophisticated exploration concepts and technology
must be employed to maintain and, if possible, add to the reserve
base. Most of the world's fuel-mineral resources are in sedimentary
rocks. Any procedure or concept that helps describe, under stand,
and predict the external geometry and internal attributes of major
sedimentary units can therefore contribute to discovery and
recovery of coal, uranium, and petroleum. While conceding the
desirability of renewable and nonpolluting energy supply from
gravitational, wind, or solar sources, the widespread deployment of
these systems lies far in the future-thus the continued commercial
emphasis on conventional nonrenewable fuel mineral resources, even
though their relative significance will fluctuate with time. For
example, a decade ago the progilostications for uranium were
uniformly optimistic. But in the early 1980s the uranium picture is
quite sombre, although unlikely to remain permanently depressed.
Whether uranium soars to the heights of early expectations remains
to be seen. Problems of waste disposal and public acceptance
persist. Fusion reactors may ultimately eliminate the need for
uranium in power generation, but for the next few decades there
will be continued demand for uranium to fuel existing power plants
and those that come on stream. This book is, to some extent, a
hybrid."
