363The Mineral Industry of Louisiana 
 
This chapter has been prepared under a cooperative agreement between the
Bureau of Mines, US. Department of the Interior, and the Louisiana Geological
Survey for collecting information on all minerals except fuels.

Loui~iana mineral output in 1967 was 
valued at $4.0 billion, 15.5 percent more than the 1966 value. For the 10th
consecutive year, Louisiana ranked second to Texas in value of mineral production.
New records resulted from output of crude petroleum, natural gas, natural
gas liquids, sulfur, salt, and sand and gravel. 
 
 Hydrocarbon fuels—crude petroleum, natural gas, and natural gas liquids—provided
93 percent of the total value of mineral output. Fewer new discoveries were
made in 1967 as only 13 oilfields and 17 gasfields were recorded (24 onshore
and six offshore). A net crude reserve increase of 47.5 million barrels established
a new high for recoverable reserves ia the State. Changes due to extensions,
revisions, and new pools in old fields accounted for 724.2 
m~ilhon barrels of crude reserve; new field discoveries accounted for only
3.2 million barrels. In quantity of reserves added during 1967, Louisiana
ranked first in the Nation in natural gas and natural gas liquids, and third
in crude petroleum. 
 
Trends and Developments.—Despite 
labor troubles during the year, investment in new or expanded manufacturing
facilities in the State was at a record high. Since 1962, the State has experienced
a rise in industrial spending. The Louisiana State Board of Commerce and
Industry approved ad valorem tax exemption applications representing a total
investment of $595.2 million.
