Hewitt Oil Field 211 
THE HEWITT OIL FIELD, CARTER COUNTY, OKLAHOMA. 
LouIs ROARK. 
Introduction. 
The Hewitt Oil Field which is one of the most important fields in 
Oklahoma is located in the western part of Carter County, Oklahoma. 
The field was discovered June 1, 1919, by the Texas Company, when 
their well No. 1, on the A. E. Denny lease, was drilled in with an initial 
production of 410 barrels flowing. This well is located in the northeast 
corner of the NW. % of the NW. % of the NW. % of section 27, 
Township 4 South, Range 2 West. This discovery well of the field is 
located on the south edge of the field and is now an edge well. 
Since the bringing in of this well development has been very rapid 
until at the present time there are about 550 producing wells with an 
average daily production of about 45,000 barrels of oil. As yet the field 
has not reached its maximum production.. 
The writer commenced studying the geological conditions of this 
field for the Roxana Petroleum Corporation in January, 1920, and 
spent about five months’ time on the work. A report was submitted 
the latter part of June, 1920. 
At the present time the Carter Oil Company, the Wolverine Oil 
Company, the Westheimer and Daube interests and the Humble Oil 
and Refining Company are the largest producers in the field. The 
Carter Oil Company is leading in production with a daily average of 
about 9,000 barrels. The specific gravity of the oil varies from 34 de- 
grees to 38 degrees Baume. 
The writer is greatly indebted to the Roxana Petroleum Corpora- 
tion for giving permission to publish this article and to Mr. R. A. 
Conkling, head geologist of the Roxana Petroleum Corporation, under 
whose supervision this work was done, for his advice and suggestions. 
Location and Area of the Field.

The field is 3 miles east of the southeast extension of the Healdton 
field and about 12 miles southwest of the western part of the Arbuckle 
mountains. The field covers an area of 6 to 7 square miles. There are 
13 sections in the township with producing wells as follows: Sections 
9,10; 16, 21, 22, 10, 28, 25, 26, 27, 28, 35 and 36, of which the first five 
are the principal producing sections.

The relief of the Hewitt field proper is about 100 feet. The highest 
point is near the southwest side of the field in the southwest corner
