jgO PETROLEUM AND NATURAL GAS. 



Creek District, and is frequently gas-bearing in Freemans 

 Creek, Hackers Creek, Courthouse and Collins Settlement Dis- 

 tricts.' In Gilmer, it produces oil at Newberne and in the ex- 

 treme western corner of Dekalb District and gas at other lo- 

 calities. This sand was formerly believed to be the Gantz of 

 the Catskill Series and has been so termed generally by the 

 drillers, but studies by Hennen and the writer in Calhoun and 

 Doddridge show that the Berea Sand of the Yellow Creek field 

 in Calhoun and the oil sand of the Fink region are the same, 

 and since the identity of the Yellow Creek Sand has never 

 been subject to question, the oil sand of Fink Creek must be 

 called the Berea instead of the Gantz. 



Gantz Sand. The Gantz Sand, which is the uppermost 

 sandstone member of the Catskill Series, belonging 400 to 500 

 feet below the top of the Big Lime, and being usually 10 to 

 30 feet thick, has produced a little gas in northern Lewis, but 

 is not generally productive. 



Fifty-foot Sand. The Fifty-foot Sand, belonging next 

 under the Gantz, and coming 450 to 550 feet below the top of 

 the Big Lime, and being 20 to 50 feet thick, is an occasional 

 producer of gas in northern Lewis. It frequently contains 

 large quantities of salt water and some good wells have been 

 completely drowned out by drilling too deep in the sand. No 

 productive wells in this horizon were noted in Gilmer. 



Thirty-foot Sand. The Thirty-foot Sand, coming 500 to 

 600 feet below the top of the Lime, and much resembling the 

 Fifty-foot in thickness and character, is not generally produc- 

 tive, but. has furnished gas at a few wells in northern Lewis. 



Gordon Stray Sand. The Gordon Stray Sand, coming 600 

 to 650 feet below the top of the Lime and seldom being more 

 than 20 feet thick, produces gas at scattered points in Lewis 

 and at one or two wells in Glenville District, Gilmer, near the 

 Lewis Line. It has also furnished oil at a few wells in the 

 Copley region, Courthouse District, Lewis. Like all the other 

 sands of the Catskill Series, it is lenticular, making its correla- 

 tion somewhat uncertain. 



Gordon Sand. The Gordon Sand, coming 600 to 700 feet 

 below the top of the Lime, and being usually 5 to 30 feet thick, 

 is one of the most prolific oil and gas horizons of the two
