j am HeTeDy uDlhllllHS u u, VI youT MY
report of the Geological and Electro-Magnetic Survey of your
block of leases mainly located on the Dixon and Dobson Ranch
in Twp. 2S. Range Is East in Craig County, Oklahoma.
LOCATION OF LEASES.
This block of leases is located on the Eastern edge of one
of tie largest and most extensive producing Oil Pools of the
entire Mid-Continent field. About fifteen niles to the south
and west lies the Eastern edge of the famous Nowata Oil field
n which over 5000 producing wells have been drilled. About
forty miles to the west Of your block of leases is the famous
Bartlesv lie Oil and Gas field in which over s 900 producing
wells have been drilled in. A few miles from you in Craig
county is the Weimer field with a number of shallow produc-
ing wells.
PRODUCTION STATISTICS.
wish to specifically call your attention to the Plat of his
report which is based upon the actual production statistics of
the Kansas and Oklahoma OIL Fields. This plate positively
shows that you are on the extreme Eastern edge OF the heav-
fest and most extensive oil structure in the Mid-Continent
field.
This structure has a trend slightly Northeast and southwest
and is almost continuous for nearly $50 miles along the trend
of production from North to South.
also wish to most emphatically call your attention to the
probable production area map of Oklahoma which is shown by
plate 2. This plate is an exact copy of plate ! on page q,
Bulletin No. 10 of the Oklahoma Geological Survey which
able production.
In this report can not make it sufficiently exhaustive to
go into the general details OF the stratigraphy and Topography
Of the territory in which this block of leases is located but will
give sufficient details to enable you TO form an intelligent op-
inion of the structural conditions in this territory.
PETROLEUM GEOLOGY.
Petroleum Geology is practically 4 classified history OF the
Earths crust as told by its rocks and fossils. and the cardinal
principal of petroleum Geology is folding and on the Earth's
surface in various places the land has been uplifted or depress-
ed either by conclusive action or by crust movements involving
centuries of time. These crust movements have caused arches
or anticl'nes, and troughs or synclines and q large per cent OF
the Worlds oil fields have been found on arched folds or anti
clines, or some modification Of an Earth fold, such as a dome
monocline or terrace. Where a fold is found in oil bearing
territory, there is a possibility Of securing production.
The Earths history Is divided into five major Geological
eras having many subdivisions. Your block Of leases is locat-
ed in the Paleozoic Era and the Carboniferous system of this
era and the Pennsylvania series Of the Carboniferous system.
A large per cent of all the Oil production Of the Mid-Contnent
field has been in the Carbonferous system, and practically all
the heavy production OF the Northeastern Oklahoma has been
in the Pennsylvania series. consequently your block of leases
is located in the proper Geological era system and series to be
productive.
THE DIRECTION OF THE MISSISsIPPlAN INCLINA-
TION.--In this territory the erosion on the Mississippan is
slightly irregular as has been proven by drill records and its
upper surface dips to the west at approximately 80 feet per
mile with a slight dip to the north. In a northerly direction
