Title: Nepheline Basalt in Richland Parish Gas Field, Louisiana

Author(s): Ian Campbell (2), A. D. Miller (3)


The writers describe briefly the geology of the new Richland Parish as field of Louisiana, and the petrography of nepheline basalt discovered in the drilling. Gas was first encountered in this field in a well of the Gulf Refining Company in October, 1926. Development has proved a structure 14 miles long and 8 miles wide, with 150 feet of closure. Production comes presumably from the Glen Rose Trinity at depths ranging from 2,300 feet to 2,400 feet. An igneous rock was encountered in a well on the south flank of the structure, just below the Midway. It is a true nepheline basalt, of surficial type. Its age is probably late Cretaceous.
