of section 22, Township 4 South, Range 2 West. This point has an 
elevation of 929 feet above sea level and the lowest point is along the 
bottom of Bayou Creek which passes thru the northern and eastern 
portion of the field. The elevation of this flood plain is 837 feet above 
sea level. There are no steep escarpments along the sides of the valley. 
The topography may be classed as late maturity in age since the area 
is well drained and the larger streams have developed flood plains to 
some extent. 
The field is drained by Bayou Creek and its tributary streams. 
Bayou Creek flows southeast and empties into Red River and thence into 
the Mississippi River. " 
The production in Hewitt is not confined to a major divide as in 
Healdton. Wells are found on the highland and also in the bottom along 
Bayou Creek and its tributaries. 
The Hewitt field was covered for the most part with scrub oak 
timber, commonly known as black jack, at the time the discovery well 
was drilled. This timber has been greatly removed and thinned during 
the progress of development of the field. 
Stratigraphy. 
The generalized geologic section of Southern Oklahoma as given by 
J. A. Taff in his report on the Geology of the Arbuckle and Wichita 
Mountains, U. S. G. S. Prof. Paper No. 31, is shown below, and a brief 
description is also given of those principal formations that occur in the 
Hewitt field.

Cretaceous.—The Cretaceous occurs in the Hewitt field only as a 
capping for a few of the highest hills and consists of undifferentiated 
sand and gravel and is of little or no importance. 
Permian.—The undifferentiated red beds of the Permian which cov- 
ers the Hewitt field to a depth of 50 to 400 feet, consist of alternating 
beds of red, gray and white shale, and brown, white and red sand- 
stones. The Permian is thinnest near the center of the subsurface 
structural high as mapped, this high being about the center of the field 
as now outlined. The Red Beds, as the Permian is commonly called,
