Structure and Oil and Gas Resources of the Osage Reservation, Oklahoma (open access)

Structure and Oil and Gas Resources of the Osage Reservation, Oklahoma

From Introduction: "Responding to the imperative need for increasing to the utmost the petroleum supply of the United States, the Geological Survey, since we entered the war, has largely concentrated its investigations of oil fields in the most promising undeveloped territory, such as Wyoming and the midcontinent-Texas region, and especially in the Osage Reservation in Oklahoma. This report is therefore issued to supply an evident need for geologic information regarding the Osage lands. In the separate papers the most practical and immediately available conclusions reached by geologists as to the structure and oil prospects in the townships already examined are published for the immediate use of the oil man."
