The first commercially viable oil deposit in the Czech Republic was discovered below the dried-out Nesyt Pond in 1919. Based on observations of natural oil and gas seeps, the first 217 meter-deep exploration well was situated in the old streambed of the Morava River. Recoverable crude oil accumulations were discovered at the end of 1919 and an oil production license was subsequently awarded to Moravská těžební společnost (Moravian Oil Company). Drilling operations continued until the beginning of the 1960s.
