95. Well near Bakersfield, Kern County. 
[Well completed July 3, 1901. Authority, Milo M. Garvin, driller. No samples.] 
The formations penetrated comprise beds of sandstone, sand, clay, and shale of lower 
Miocene age, the whole series representing sediments brought down from the mountains to 
the east. The oil-bearing horizons in the Kern River field have been defined, but the logs 
of wells a short distance apart show great variations and no attempt has been made to 
differentiate the beds into distinct formations.
