When was the first oil rig built?

The first oil rig is generally considered to be the one built by Edwin Drake in 1859 in Titusville, Pennsylvania. This rig, known as the Drake Well, marked the beginning of the modern petroleum industry and was a significant advancement in oil extraction techniques.
