WEST VIRGINIA GEOLOGICAL SURVEY. 381 



The Murphy Creek Oil Pool, located north of Murphy 

 Creek, along the Courthouse-Freemans Creek District Line, 

 contains from 10 to 12 producing oil wells, the pay sand being 

 about 1300 feet below the Pittsburgh Coal, and apparently 

 being the lower Salt Sand, or the basal sand formation of the 

 Pottsville Series. It is possibly the same as the Salt Sand of 

 Rosedale, which is also the lowest sand of the Pottsville, but 

 the Rosedale Sand is 1625 feet below the Pittsburgh horizon, 

 the difference of 325 feet in interval representing the south- 

 ward expansion of the Pottsville, which is nearly 800 feet 

 thick at Rosedale, but only 500 feet on Murphy Creek. The 

 wells vary in size from 2 to 40 barrels daily. The five follow- 

 ing records are from this pool :
