trouble was that where there was frac-
turing of the formations sufficient to al
low the oil TO escape to the surface. there
was seldom a structural condition pres
ent, to provide a trap for the oil But
the theory applies today in soil ANALYSIS
where the structure is first established
and then the surface of the soil is ex-
amtned with a microscope to determine
whether there are evidences of oil and
gas seeping up through to the surface.
We have known for many years about
the peculiar wax-lilxe material which
shows on the surface of the ground i'm
Salt Greek field. That evidence of oil be-
meath is unmistakabIe, although it was
not recognized until many years after
Salt Greek was a producing oil field But
IL goes to show there IS an escape of GER
tain hydrocarbons from a pool of oil.
The hydrocarbOn vapOrs under relatively
high prcssures and temperatures will
tend to move toward areas of lower tenn
perature and pressures. This means that
the migration will be vertical and the
gases Will diffuse toward the surface
through rocks and shales otherwise inn
pervious to oil gas or water. The gases
move upward through the minute pore
spaces and fractures i'm the rocks and pass
through water-saturated zones, as the
liquid is not "a barrier. Since all rocks
are made mp of fine particles, there is
enough pore space between these par
ticles to allow the passage of light gas
through them is possible.
Accordingly, the scientist takes a sam
pie OF the soil and measures the con-
tent OF hydrocarbons, which range from
methane through the heavier gases to
wakes and asphalts. From a large num-
Der of samples, taken at regularly spac-
ed intervals, the scientist determines that
there are more hydrocarbons i'm one To-
cation than in another, and thus he de-
termines the area of probable oil col
lection.
Many volumes written on each of
these important sciences, all of which
have added permanence and profit to the
oil industry. The man who makes an i'm
in the oil industry today takes
advantage of all these wonderful accom-
pIishments of science. His investment is
sounder than ever before. The risk is
less.
These things are of particular inter-
est to MOntanans for this is the one
spot where the new sciences have scarce
Nv been introduced. Acidization is here, as
applied to lime formations. But rotary
drilling has barely arrived; geophysics {
have barely arrived; soil analysis is Just Z
coming. Deep drilling is yet to come. We

We believe that these sciences can be
pest capitalized by the purchase in Mon
tana of leases and royalties. For the
mail investor, royalties appear to us to
le the most desirable investment, since
he owner does not enter into any Obliga-
ions such as lease rentals and drilling
requirements. The royalty owner gets e
given share of the oil when It is pro-
iuced and it is delivered to him free :.
Il cost of production. If he buys royalty
It fair price, with protection of a good 3
title, he can well afford TO wait fore g
hat development, especially where he is
informed as to coming events. 9
