reflects production and net additions and withdrawals in storage. 
 
3,334,730 barrels per day for the State was established in August. An additional
800,000 barrels per day of natural gas liquids was also recovered. This response
showed the oil industry capability to meet a national crisis on relatively
short notice. The industry achieved the record pro- 
 
duction in a little over 2 months with the State market-demand factor rising
from 33.8 percent in June to 54 percent in August. The previous record high,
under similar Mideast war conditions in 1956, was 3,280,078 barrels per day
when operators were producing at an allowable
