The Stanolind No. 1 Government-Maine, Sec. 19, T. 44 N., R. 81 W., opened a new Tensleep pool late in 1951. The North Fork area is 23 miles northwest of the nearest Tensleep field and is the northernmost Tensleep production on the west side of the Powder River basin. Discovery of a narrow, southeast plunging anticline was made by surface reconnaissance work. Later seismograph mapping showed a closed anticline, faulted on the southwest side, at depth. The field has not been delineated but based on seismograph data and the pay section encountered in the discovery well, it appears that a reserve of several million barrels is present.
