MMcfd. Liquid production of demethanized mix should rise from 1,900 barrels
per day to about 6,800. Expansion plans followed FPC approval of Florida
Gas Transmission Co.'s line enlargements between Louisiana and Florida, allowing
bigger deliveries. 
 Sun Oil Co. completed a 1 75-MMcfd 
plant in Belle Isle field, St. Mary Parish. 
Other plants completed during the year 
were: Coastal States Gas Produding Co. 
South Manchester plant, Calcasieu Parish; 
Humble Thibodaux plant La Fourche 
Parish; Sunray DX Bayou Sale plant, St. 
Mary Parish; Union Oil Co. of California 
Houma plant, Terrebonne Parish; Placid 
Patterson plant in St. Mary Parish; and 
Black Lake plant in Natchitoches Parish. Capacity of underground storage
facilities increased 22.8 percent. As reported by The Oil & Gas Journal's,
annual survey, capacity was 16.0 million barrels of natural gas liquids and
2.8 million barrels of ethylene at yearend, not including projects under
construction or planned. 
 
 Pctrolèum.—The petroleum industry of Louisiana established
a production record of 774.5 million barrels, 15 percent higher than the
1966 record production and second highest in the Nation. Petroleum was produced
in all but seven of the 64 parishes in Louisiana. Daily allowable production
at the end of 1966 was 36 percent of depth-bracket aliowabl~. This rate continued
in January and February of 1967, decreased to 35 percent for March and April,
and to 34 percent for May and June. On June 5, hosilities between Israel
and the Arab nations precipitated a worldwide petroleum supply crisis, and
the domestic petroleum industry was requested to supply a part of the oil
ordinarily provided by the Arab countries. As most of the reserve crude oil
productive capacity in the United States is in Louisiana and Texas, these
States supplied virtually all of the domestic crude oil production increase
during the crisis; most of this extra production was shipped to European
countries. 
 The Louisiana Department of Conservation took immediate action to adjust
well and field allowables in accordance with indicated increase in demand.
As a result of an emergency meeting with major crude oil producers on June
20, a special order was issued increasing the demand factor from 34 percent
in June to 38 percent in

July. The intermediate zone allowable was increased from 115 to 130 percent
of the onshore allowable. The production and transportation of crude oil
up to 150 percent of the June allowable was also authorized, overproduction
to be compensated by underproduction in a later month. This allowed operators
to achieve the major production increase from selected wells
