Description

Newton (1941) discussed a Stewardson Anticline but stated that he was not sure of its existence and did not indicate closure on his structure map. Only three subsurface control points were used by Newton. Subsequent development of the Stewardson Oil Field disclosed a roughly circular dome about 1 mile (1.6 km) in diameter and having about 20 feet (6 m) of closure on the Beech Creek ("Barlow") Limestone and Karnak Limestone Member of the Renault Limestone (ISGS open files). DuBois' (1951) maps on several Pennsylvanian units also indicate the dome. The name Stewardson Anticline should therefore be changed to Stewardson Dome.

The Stewardson Oil Field has produced more than 1.1 million barrels of oil from 28 wells completed in the Aux Vases and Spar Mountain Sandstones.
