The exploration geologist is concerned with regional
geology deduced from surface outcrop, geophysical surveys, and
the results of any boreholes drilled in the area. In spite of the
enormous advances in geophysical techniques, the stratigraphy
of the area may only be determinable in a rather general sense.
The development geologist, on the other hand, is concerned with
the detailed stratigraphic sequence, and its structure, over a
relatively small area. Yet this detailed stratigraphic sequence is
not obtained from a study of the rocks themselves, but rather
from the electrical and other geophysical reasons obtained in the
boreholes.
It is commonly said that the petroleum geologist has the
advantage of working without financial restraint. This is rarely,
if ever, true. It is true that many areas are investigated using
several disciplines, some of which (geophysics, drilling) are very
expensive to apply, but all will be operating under some
financial restraint. It is not so often said, but is nevertheless true,
