found in the Ohio shales, but the quantity was of no value, and the well 
must be recorded with the failures. 
Preparations were being made in 1902 to drill additional deep wells in 
the county, the objective stratum being the Jefferson gas rock, which has 
elsewhere been shown to belong to the Lower Helderberg. 
LORAIN COUNTY. 
The Berea grit forms the surface rock of the greater part of this coun- 
ty. Oil was discovered in the formation about 1860. The test well is said 
to have been drilled because of the usual surface indications. At a depth 
of about 65 feet a heavy oil was found, but the quantity was so small that 
it produced little or no excitement. 
No further work is reported for 15 years, when another well was 
drilled on the same farm. This is said to have been a relatively large pro- 
ducer. The oil proved to be a good lubricator, and found a ready market 
in Cleveland and adjacent places. This well produced considerable excite- 
ment, some farms selling for four times their previous value. The excite- 
ment lasted two or three years, but there was some drilling as late as 1880. 
A. few of the wells are reported to have started as high as 100 barrels per 
day, but the decline was rapid. Several of these wells are still pumped 
occasionally. Within the past few years a number of additional wells have 
been drilled in this territory, but the results have been disappointing. The 
field is commonly known as the Belden. 
Near Ehart, in the southwestern corner of the county, several Berea 
wells have-been drilled within the past few years. A small quantity of oil 
was found, and the. wells were pumped for a short time, but the results 
were not commensurate with the energy and money expended. 
MEDINA COUNTY. 
Around the village Lodi, in the southern part of the county, a small 
oil field has been developed. The territory extends nearly due north and 
south, and has a length of about three and one-half miles, and a maximum 
width of about one mile. It includes parts of Harrisville and Chatham 
townships. 
The first successful well is reported to have been drilled in 1899, on 
the farm of F. R. Shaw, near the south line of Chatham township. From 
that point holes were drilled in all directions, and at one time five strings 
of tools were kept busy, the field experiencing a small boom. In 1902 all 
was quiet, but doubtless other wells will yet be drilled. 
The best wells had an initial production of from 40 to 60 barrels per 
day, but as in all shallow territory the decline was rapid. The oil is dark 
and of about 39 degrees B. gravity. In July, 1902, the number of pro- 
ducing wells was about 70.
