WALTON, Ind. -- An Indianapolis company searching for oil across Indiana hopes an oil field that once was the largest in the United States can be lucrative again.
The Pharos-Tribune reports CountryMark is taking its search to Cass County in hopes that new technology will be able to find oil in the Trenton Oil Field that once spread beneath Peru, Walton and Delphi.
Rick Sumner of CountryMark says the field was discovered in the 1800s and produced several hundred million barrels of oil before being plugged in the 1920s.
Workers will use seismic sensors to collect data to create a kind of underground map. The map will show whether oil is present.
Work is expected to begin in about a month.
