It is believed that the production in the Toomey Nos. 1 and 2 and the 

 Hendren comes from a jointed or slightly fissured or fractured limestone, 

 either pure or dolomitic. From a comparison of the logs of the Toomey 

 No. 2 and the Hendren No. 1 it seems probable that this fissured oil- 

 bearing limestone is not at exactly the same horizon in the two wells, and 

 that the oil does not come from the same identical beds. The oil-bearing 

 rocks in the Toomey No. 2 well appear to be 40 or 50 feet higher strati- 

 graphically than in the Hendren No. 1 well, and it is possible that if the 

 former well were deepened some 50 feet a second pay might be struck. This 

 Assuring or fracturing is probably not far from the same horizon in neigh- 

 boring wells, but that it is not universal is shown by the failure to find a 

 pay sand in the West No. 1. It is possible that wells several miles apart 

 may find considerable variation in the stratigraphic horizon at which fis- 

 sured or dolomitized oil-bearing rocks occur, and until the character arid 

 oil-bearing features of these Newman limestones become better known, it 

 would be desirable for future wells that fail to secure oil at about the 

 horizon productive in the Toomey or Hendren wells, to be drilled some 

 100 or 200 feet deeper to test out the possibility of porous or fissured oil- 

 bearing rocks occurring at a somewhat lower level in the Newman. 



Thickness of "sand". The thickness of the "sand" or "sands", so far 

 as known, is about 20 to 23 feet. In the Toomey 'No. 1 well it is probable 

 that a few feet below the pay there is a second pay a few feet thick ; while 

 in the Toomey No. 2 well ten feet above the main pay, there are five feet 

 of what appears to be a good sand at 945-950. 



Water. The rocks seem to contain comparatively little water. In some 

 of the wells no mention is made of it at all. It is possible that drilling 

 about Oneida or east of there where the rocks are considerably lower may 

 find more water than is found farther west if the strata contain any not- 

 able amount of water anywhere. 



Gas. Very little gas has been encountered. 



Production. No adequate tests have been made of the daily capacity 

 of any of the wells as yet. The Toomey No. 1 was pumped from 3 to 9
