using local brines, and at Maceio, Salgema Industrias Quimicas, S.A., an
affiliate of E.I. duPont de Nemours & Co., was building a plant to have
initial annual capacity of 250,000 tons of caustic soda and 220,000 tons
of chlorine. 
ment of the offshore Guaricema and Caioba fields continued; these fields
are expected to begin producing during the first half of 1973. 
 Drilling activities of Petróleo Brasileird, S.A. (PETROBRAS), are
summarized as follows: 
MINERAL FUELS 
Coal.—Production of raw coal in 1972 was 5% higher than in 1971, but
there was little change in production of washed coal. In Santa Catarina only
31% of the raw coal was usable. Data on produ-ction follow, in thousand metric
tons:

Steam coal accounted for 57% of the washed coal from Santa Catarina. 
 Brazil and Colombia formed a joint commission to study the possibility of
exporting -Colombian coal to Brazil. In view of expanding iron and steel
capacity, it is estimated that Brazil will need 30 million tons of coal,
mostly coking coal, during the next 8 years. 
Petroleum and Natural Gas.—Production 
of crude petroleum, at 61.1 million barrels in 1972, was 1.5% less than in
1971. Natural gas output increased 5:5% to 43,860 million cubic feet. Production
of natural gas liquids reached 1,495,000 barrels, a gain of 9% over 1971.
Production of crude oil originated in Bahia (82.5%) and in Alagoas and Sergipe
(17.5%). Secondary recovery methods were used in 10 fields in Bahia and in
two fields in Sergipe. Production from offshore wells amounted to 3,466,000
barrels, or about 6% of the total. 
 At yearend, reserves of petroleum stood at 799 million barrels, and natural
gas reserves at 922.3 billion cubic feet. Exploration for additional supplies
continued during the year. Significant results included confirmation of the
Camorim field, offshore in Sergipe, as a potential producer, and drilling
of two wells showing oil and gas at Fazenda Cedro, Espirito Santo. Develop-

 PETROBRAS operated six refineries during the year, with a throughput of
207.1 million barrels, and the private refineries consumed an additional
21.4 million barrels. Imported crude made up 76% of the total. The Planalto
refinery at -Campinas, São Paulo, was completed and placed in service
on May 12, making PETRO-BRAS's total capacity 673,000 barrels daily. The
refinery includes units for distillation, cracking, treatment of lighter
fractions, and sulfur removal; pollution control measures were extensive.
Crude is delivered from São Sebastião through a 234-kilometer
pipeline. 
 Three storage tanks containing liquefied petroleum gas were destroyed by
fire and explosions at PETROBRAS's Duque de Caxlas refinery in March. Property
damage was estimated at $1.7 million. Normal refinery operations were not
affected. Late in June a crude oil pipeline from the ocean terminal on Ilha
d'Agua in Guanabara Bay to the refinery developed a leak, causing a serious
pollution problem. - 
 In February PETROBRAS created two new subsidiaries, and became a participant
in a third. The Cia. Petróleo da Amazônia (COPAM) was formed
to take over the operation and expansion of a refinery in which PETROBRAS
had obtained a 67% interest. The refinery, in Manaus, had been owned by the
Sabbá group and had a capacity of about 8,000 barrels per day. At
yearend, COPAM was expanding facili
