Developments in Texas and Oklahoma panhandles in 1957

Exploratory drilling activity in the Panhandle District during 1957 surpassed 1956 by 12%. In all, 205 exploratory tests were drilled, of which 70 (34%) were successful. Field development wells declined slightly from 1956 as the success ratio dropped to 91%. Discoveries were predominantly from Pennsylvanian reservoirs, within the Anadarko basin, with 55% of these being completed from the Morrow series. Geophysical activity remained high, with a 10% increase in seismic crew-weeks. Leasing activity continued at a high peak as the Palo Duro basin underwent a large lease play after discovery of Pennsylvanian oil in Oldham County, Texas.
