feet from Sheaffer Oil & Refining

the early 20s and abandoned in
1889. This well repeatedly had an
initial production of about 100 bar

So far, the Chamberlain and
Gamer wells are the only ones on
the West Dome to go beneath the
old pay horizons that yielded mil
lions of dollars worth of high-grav-
ity crude, with the exception of a
well drilled on the south flank of
the dome, on the old Lucky Strike
lease, that got water in all horizons.
