 Chilean metallurgical coke production, reported at approximately 212,600
tons for 1965, was the result of blending imported U.S. medium-volatile bituminous
and locally produced high-volatile bituminous coals. The blend ratio remained
about the same as in previous years, with 125,000 tons imported for mixing
with 188,000 tons of Chilean coal. Gashouse coke production was estimated
at 81,000 tons in 1965, a slight reduction from that of 1964. 
 NaturaL Gas.—Chilean natural gas production declined about 1 percent
from 1964 output. Of total 1965 production, 72 percent, or 157,582 million
cubic feet, was reinjected for repressuring or storage. The remainder was
flared or was used for heating or power generation at the Empresa Nacional
del Petrdleo (ENAP) facilities for operation of a small generating plant
at Punta Arenas. 
 Petroleum.—Chilean petroleum production in 1965 decreased 7.2 percent
from that of 1964 after registering a 3.6-percent gain in 1964 over that
of 1963. Some of this reduction was charged to an 8-day strike in April at
ENAP facilities, and part was credited to a lack of new wells being brought
into production. The nation's 1965 output probably ranked Chile sixth among
South American producers, following Venezuela, Argentina, Colombia, Brazil,
and Peru. The Daniel oilfield (on the Chilean mainland) remained the largest
producer in 1965, though its percentage of total production decreased from
37 to about 35 percent. Approximately 49 percent of total production came
from mainland fields in 1965, compared with 52 percent in 1964. 
 According to ENAP's annual report, exploratory wells drilled in 1965 were
generally unproductive though some gas accumulations were found. In the Magallanes
Zone, 4 seismic crews operated during the year, and some 40 exploration and
extension wells were recommended for the Terciaria and Springhill districts.
Magallanes Zone drilling during 1965 was reported as follows:

 In the Central-South Zone, two seismic crews which had been operating during
1965 finished work in November. Four exploratory wells had been put down
with generally negative results. A program for future exploration calls for
drilling in the Provinces of Llanquihue, CautIn, Nuble, and Arauco. 
 Part of Chile's output of crude oil and gas was processed by the topping
plant in the Manantiales area and the gas plant at the Cullen field on the
Island of Tierra del Fuego. The major Chilean refinery at Concón,
was only lightly affected by the March earthquake and processed 16,857,200
barrels of crude oil during 1965. Feed to the plant was 70 percent Chilean
crude oil and 30 percent imported. The combined output of these plants enabled
the country to be self-sufficient in motor and aviation gasolines, kerosine,
and liquid petroleum gas. About 85 percent of the demand for diesel and 50
percent of that for fuel oil were also met by the domestic refineries. 
 Construction work on the new refinery at Concepción, which will have
a daily throughput capacity of 35,850 barrels, progressed on schedule, and
at yearend the marine terminal at San Vicente, associated with the refinery,
was equipped. 
 Prior to 1965, the Concón-Maipu pipeline 18 had been completed to
San Fernando, and studies had beed approved for the construction of a pipeline
from Concepción to San Fernando, where it would join with the Concón-Maipu
line. Thus, the refinery at Concón and the new plant under construction
in ConcepciiSn would be connected and able to supply the demands of the Central
Valley of Chile. At yearend, these studies had been completed, and construction
was projected to start in early 1966. 
 During 1965, development of plans continued for the projected Chilean petrochemical
industry, which will be under the direction of CORFO and ENAP.19
