Oil Production In Texas. Background. Oil was first detected in Texas in July of 1543 when Spanish explorer Luis de Moscoso of the DeSoto expedition saw oil floating on the water in the Galveston Bay in an area between High Island and the Sabine Pass, near Port Arthur, Texas. The first economically significant oil discovery in Texas did not happen for another 300 years.
