102 SANTA MARIA OIL DISTRICT, CALIFORNIA. 
folds occur on this flank, one apparently passing through Western 
Union wells Nos. 21 and 22 and the other occurring from three-eighths 
to five-eighths of a mile farther northwest. The Newlove anticline as 
shown on the map is wholly hypothetical. It is the expression of the 
most plausible explanation of the relationship which is supposed 
to exist between the known Graciosa-Western Union and the eastern 
Western Union well areas. The surface evidence of the structure 
consists of a 10° SE. dip in the Fernando beds just north of the 
Graciosa wells, together with some more or less uncertain dips in the 
Monterey toward the head of the ridge, approximately parallel with 
which the anticline is supposed to run. 
GEOLOGY OF THE WELLS. 
The wells all start in the sands of the Fernando, penetrating this 
formation for 70 to 300 feet. No water is reported from this sand, 
but asphaltum is said to have been found at its base in one of the 
wells. From the base of the Fernando to the top of the main pro¬ 
ductive zone the formation consists of blue and brown shales with 
many hard “shell” layers, some beds of sticky shale, and rarely a 
little sandy material. Streaks of asphaltum are reported as occur¬ 
ring in the shale in some of the wells, and in others gas is present 
under some of the “shells.” 
The first oil zone (B of the^ northern part of the field) is reported 
from only one well, where it is nearly 200 feet thick and is encountered 
at a depth of about 2,075 feet. Gas is associated with the oil in this 
zone. 
The second and important oil zone of this area (C) is struck at 
depths ranging from 2,670 to something more than 3,800 feet, and 
lies about 600 feet lower in the wells than zone B, which is apparently 
unproductive in most of the wells. According to the data in hand, 
the productive zone ranges in thickness from 18 to about 240 feet 
and consists of alternating light and dark flinty shales interbedded 
with varying amounts of sandy shale. No true sand, as ordinarily 
implied by the name, occurs in the productive zone of this area, so 
far as the writers were able to learn. 
PRODUCT. 
The oil from zone C runs from 25° to 27° Baume, averaging well 
up between 26° and 27°, and has a brownish color. It comes from 
the wells at a temperature of about 95° F. and is usually accompanied 
by much gas. Certain of the wells, however, are said to show a 
comparatively low gas pressure. 
The production of the individual wells ranges from 300 to 3,000 
barrels per day, the flow of many being unusually strong. None of 
the wells have been allowed to produce up to their full capacity,
