Penwell
Historical marker location:Birthplace of Ector County's Oil boom. First civic development here was wide-open town, "Derrick City", platted March 1927, after Dec. 28, 1926, oil discovery by driller Josh Cosden on land of W. E. Connell, near the old farming and cattle station, Judkins.
However, when Connell well began pumping only 20 barrels a day, the boom crowd moved away. The city was abandoned.
As nearby counties off the railroad struck oil that had to be shipped by the Texas & Pacific to refineries, Ector County in 1927 had a "Truck Drivers Boom" --a foretaste of the leadership in supply and servicing that was to develop progressively.
Then on Oct. 14, 1929, on Robert Penn's land here, a 375-barrel per day well came in. With that showing, exploration continued, soon followed by the Penn Well, the 600 to 700-barrel a day gusher.
In a busy, bustling and prosperous tent city, the Penwell Post Office was established June 30, 1930. This has remained a central distributing and shipping point for numerous fields in several permian basin counties, thereby establishing and earned reputation as "The Crossroads of the oil patch".
