NOTES. 



In drilling an oil well, the measures passed through are necessarily 

 divided into three groups or divisions. Each one of these divisions requires 

 a specific treatment at the hands of the driller. 



• The first division is comi)osed of Drift or the loose surface accumulations 

 from the surrounding rocks ; the second embraces the immediately under- 

 lying series of stratified rocks to the depth at which they contain water ; 

 and the third, the remainder of the well, including the oil sands at the 

 bottom. The walls of the third division are generally self-sui)p()rting, 

 remaining just as the drill leaves them, and this division, when the well is 

 completed, is the only one where the rocky walls are bare.
