SANTA MARIA OIL DISTRICT, CALIFORNIA. 
REFINERIES. 
The principal refineries utilizing the oil from the Santa Maria dis¬ 
trict are as follows: 
California Petroleum Refineries , Limited. —The refinery of this 
newly organized company is now in course of erection at Oil Port, 
south of Port Harford. It is said that the initial capacity of this 
refinery will be about 7,000 barrels per day, and that all the usual 
products will be refined. 
Pacific Oil Transportation Company. —The refinery of this com¬ 
pany is located at Gaviota, and consists of nine stills with a capacity 
of 1,050 barrels of crude oil per day. The principal products are 
illuminants and fuel residue. 
Standard Oil Company. —The plant of this company is located at 
Point Richmond, Contra Costa County, and is said to consist of 19 
stills with a capacity of 5,000 barrels of crude oil and 4,000 barrels 
re-run per day. The products are illuminants, lubricants, and coke. 
Union Oil Company of California.— The main refinery of this com¬ 
pany is located at Oleum, Contra Costa County, and consists of a 
number of stills capable of producing illuminants, distillate, and 
asphalt. 
UTILIZATION OF THE OIL. 
Most of the oil from the Santa Maria district is refined, the lighter 
products being used for illuminants and for the direct generation of 
power in gas engines, and the heavier products and unrefined heavy 
oil for fuel, lubricants, road dressing, etc. With the exception of 
a very small amount used locally, all the oil is sent out of the district, 
the greater part of the product at present, it is believed, going to the 
refineries near San Francisco. Contracts recently made in South 
America, Japan, and the Hawaiian Islands indicate that within a 
short time much of the product of the district will be exported. 
11ESUME. 
The Santa Maria oil district, comprising the Santa Maria, Lompoc, 
Arroyo Grande, and Huasna fields, occupies the central and northern 
portions of the Lompoc and Guadalupe quadrangles, northern Santa 
Barbara County; the southern part of the San Luis quadrangle, 
southern San Luis Obispo County, and a small part of the unmapped 
area between the Lompoc and San Luis quadrangles. 
The* larger part of the district is a basin region inclosed between 
two divisions of the Coast Ranges—the San Rafael and Santa Ynez 
mountains—and the Pacific Ocean. The formations in this basin 
have undergone less disturbance than in the mountains and the con¬ 
ditions in it are good for the accumulation of oil.
