HOW TO INCREASE
THE OIL PRODUCTION

the MISSISSIPPI lime. With all courtesy
TO those of the profession who believe
! it possible to produce oil from the
Mississippian and from the formation
underlying it. the writer adheres to
the contrary so far as Kansas and Ok
lahoma are concerned. and believes
that, when the drill has reached the
Mississippi lime, and it has been de.
termined that it is the Mississippi
lime. further drilling should be
stopped for further drilling means bur
a waste of time and money-time and
money which, under proper direction
would result in increased production
Of OIL Without doubt, it has hap
pened that formations enormously
called the Mississippian have been
drilled and production obtained. II is
also a fact that many wells have
ceased drilling in a formation errone-
ously classified as Mississippian, bur
we also have knowledge of wells which
have penetrated over 1000 feet Of for.

neerlng work along geological lines
In conducting such work, the geologist
is on the constant lookout for struc
lures in an area where the surface
formation indicates to him that oil
bearing sands lie within practical reacn
of the drill. II is q well-established
fact that seventy.hve per cent of the
worlds production Of petroleum is pro
duced from structural heights such as
. domes and anticlines and terraces The
remaining twenty-five per cent comes
from monoclines and from synclines
where there is no underground water
Hence the search for structural
heights. The writer is inclined tC
