Montana Oil And Mining Journal

Earl Well Is Latest To Start

Attention of Montana oil operators this week again swung toward the Rocky Mountain Basin structures when the Earl Oil company moved in a crew and prepared to resume operations in its wildcat on the sharp-dip Sun River anticline, 66 miles west of Great Falls.

This well, in NE SE 1/4 22-22N-8W, shut down last fall with hole made to 2006 feet, near the bottom of the Colorado. It has had no water since passing out of the Eagle at about 200 feet and is gassing slightly at its present depth. The well is cased nearly to bottom with 12 1/2-inch pipe and is in perfect shape for continuing.

Three Near Rockies

Resumption of operations by this well makes a total of three wildcats drilling in northern Montana, on structures near the east face of the Rockies.

Approximately 70 miles northwest of Great Falls and about 40 miles north of the Earl well, Standard of California is reported to have spudded in its wildcat in NW NE/4 NW 1/4 34-27-7W. in the Bynum district.

Top of the lime is expected at about 3,100 feet in this well and it is reported that it will be drilled to at least 4,000, making it the deepest, structurally, of any well ever drilled adjacent to the mountains in northern Montana.

Further north. east of Glacier National park and a short distance south of the Alberta line, on the Blackfeet Indian reservation, north of Browning, Fulton Petroleum company is drilling at 1625 feet in its wildcat on the sharp-dip Milk River anticline.

Blow Work

The hole is still showing a tendency to go crooked, necessitating constant re-drilling, but it is believed this trouble will diminish when hole is made to a greater depth in the Colorado shale.

These three wells are of especial interest because of their proximity to the Kevin-Sunburst field.

special interest because the
are drilling on a type of strue-
ture sharp-dip that has been
found productive both to the
north and to the south, in Al-
berta and in southern Mon-
tana.

Important Wells

So far, not a single test o
the lower formations has been
made on
any of these moun-
tain structures
in northern Montana, hence the three wells
now drilling will be watched
with extreme interest.

If they find
either oil or
gas in commercial quantities,
as geologists believe will be
the case,
dozens of similar structures in the basin adjae-
ent to the mountains will be
drilled.

It is expected that all three of the wells now drilling will
be completions inside of the
next few months.
