 The American Gas Association reported proved recoverable reserves of natural
gas liquids at yearend in Oklahoma at 455.8 million 42-gallon barrels, about
5.3 percent of the U.S. total. Exploratory drilling added 6.8 million barrels
to the recoverable reserve; development drilling added over 14.7 million
barrels through extensions and revisions to existing fields. 
 Yearend underground storage capacity of natural gas liquids amounted to
2,6 16,000 barrels at 15 (sites in seven counties. 
 Petrolcum.—Crude petroleum output totaled 230.7 million barrels from
80,970 oil wells, compared with 224.8 million barrels from 80,583 oil wells
in 1966. Daily average production of crude oil was 632,184 barrels, or 7.8
barrels per well per day—up from 7.6 barrels daily in 1966. 
Average indicated daily demand for crude oil wa.s 636,367 barrels, 5.8 percent
greater than in 1966.

 Petroleum output was prorated by the Oklahoma Corporation Commission under
the Interstate Oil Compact to maintain a balance between production and indicated
demand. The Commission retained the crude oil production allowable at 50
percent of the depth-acreage formula through March; however, for April the
allowable was reduced to 46 percent. At the request of the Oklahoma Independent
Petroleum Aasociation, the Commission altered the depth-acreage formula for
10-acre spaced
