 The field is located on the "Healdton uplift", a northwest-southeast trending anticline, which formed with the Wichita Orogeny, and is 8 miles long and up to 3 miles wide.This was followed by deposition of the Healdton sandstones and shales on pre-Pennsylvanian eroded rocks and subsequent folding during the Arbuckle Orogeny.A prospector named Palmer drilled a shallow well, 425 feet, near an oil seep in the 1890s but Federal Law prohibited oil development on "Indian lands" until the early 1900s.
