The Sweet Lake geopressured-geothermal prospect is located in northern Cameron Parish, Louisiana in T.12 S., R. 7 W. and T. 12 S., R. 8 W. approximately 10 to 15 miles south of Lake Charles. The region is characterized by Cenozoic sand and clay deposits of geosynclinal thickness and differentially uplifted salt structures. The primary geopressured-geothermal aquifer is the Miogyp sand of the Camerina zone (Upper Frio formation of Oligocene-Miocene age). The main prospect is located in a basin on the north flank of the Hackberry-Big Lake-Sweet Lake salt ridge. Interpretation of 27 miles of seismic lines and 17 deep well logs localizes the prospect in a basin with northwesterly dip in a graben between east--west faults converging eastward. Aquifer depth ranges from 14,000 to 18,000 feet. Net sand thickness exceeds 400 feet with 22% porosity. Temperatures range from 280/sup 0/F. (corrected) at 14,000 feet to 350/sup 0/F. at 18,000 feet. Geopressures occur below 9,000 feet with mud weight equivalents in the sand from 12 to 13 pounds per gallon. Net sand volume of one cubic mile is estimated in the area mapped.
