top OF the Sunburst sand, where gae
production from this formation il
contemplated, will be required in ali
! future operations in the Kevin-Sun
burst field. Copies OF new regu
Iations governing drilling and pro
darcing in the Kelvin field and the
| Sweetgrass arch are now being dis
tributed by the state railroad com
mission, which has supervision over
state and privately owned oil lands
in the state, and within the next few
days G. r. Marcy. state oil and gas
supervisor, will go to the field to be.
gin enforcement OF the rules.
The new regulations adopted by
the railroad commission are identical
with those which were drawn up by
the United States geological survey.
As the geological survey rules are
effective only on gOyernmentaIly CON
irolled or owned lands. the state
commission approved the same regu-
Iations SO as to provide uniform rules
ior the entire.
Protection OF gas is the Sunburst
sand and of oil in the Ellis form
alton is the aim Of the commission
in adopting the new regulations The
procedure required Of operators IS
considerably more involved than that
practiced in the past the most i'm
portant change being the require
ment that each string Of casing must
be thoroughly mudded in by circu-
lation OF mud fluid, before drilling
into the sand where production may
be expected
Few OF the operators in the field
are equipped at present with the nee
essary pumps for mudding casing by
circulation and it is expected that
some little time will pass before the
necessary eahsrment II available III
that development work can proceed
at it's normal pace.
All water found in drilling on the
Sweetgrass arch must be confined to
the stratum in which it is found and
test must be made to assure the
operator that complete shut off has
been made before drilling can pro-
ceed, according to one section of the
regulations.
The new rules also require that
each gas sand, regardless Of where
it is found, must be tested for volume
and pressure before drilling ahead.
Tests to determine oil bearing pOss-
Utilities Of apparently dry sands is
demanded and operators must see TO
1t that other mineral deposits drilled
through in the search for oil must be
protected against waste or damage.
If oil or gas is to be produced
from the Sunburst sand a string Of
casing, other than the CONDUCTOR
string which is used to exclude sur
face water, must be set to the top oil
the sand and be mndded in by circu-
Iating mud fluid down through the
casing. around the shoe" at it's base
and up between the outside Of the
casing and the hole. All space must
be completely filled with the fluid
and steps taken to prevent accumu-
Iation Of hard slate and lime cuttings
1t the connections, as this may cause
the casing to freeze" in the hole
The bradenhead method of produc-
ing from two horizons is required
should the operator desire to take
gas from the Sunhurst sand and oil
rom the Ellis

In this case one string Of casing is

Ind another run to point in the
black lime OF the Ellis series above

II production from the Ellis sand
,nly is planned one string of casing,
,ther than the conductor, must be

, sufficient distance above the Ellis
Iand to prevent it from being dam
lged by shooting, and the Sunburst

,e completely mudded off.
