M. P. Andrews No. 1, drilled in 1911, reached oil sands at 920 feet. Well first flowed oil, March, 1912, at rate of 10 barrels a day. Production in this shallow sand development area fell off when oil prices dropped, but rose after other pools in the region were tapped from 1916 to 1921. Since then, Archer County has become one of the state's most productive. The Hull-Silk-Sikes Well, 1939, opened a major field. More than 333 million barrels of crude oil have been produced by the county since 1911, with Andrews No. 1 still pumping. Recorded Texas Historic Landmark, 1967.
