Cretaceous production, decreased because of salt-water-disposal problems.

 Probably the most significant discovery in north Louisiana was the Pan American
Petroleum Corp. No. 1 Hodge Hunt Co. This well, completed in the Cadeville
sand (Cotton Valley, Jurassic), is 6 miles southwest of present production
and should expand the area of interest for Cadeville exploration. 
 In the Gulf Coast district, drilling activity decreased from 1966 except
for offshore exploratory wells; a sharp increase 
in offshore exploratory drilling followed the Federal lease sale in June.
The most significant new fields discovered included North Maurice field,
Lafayette Parish; Manchac POint field, West Baton Rouge Parish; Block 207
field, Ship Shoal area; and Block 144 field, Main Pass area. The Main Pass
Block 144 field discovery extends the limits of the producing Gulf Coast
salt dome basin further eastward. 
 According to The Oil & Gas Journal, 25.8 million feet of hole (32.2
million in 
1966) was drilled in the State during 1967.
