SHOLOM ALECHEM

The Sholom Alechem Field is located in eastern Stephens and northwestern Carter Counties (Fig. 1). Like many other fields of Southern Oklahoma, it has had several periods of development

HISTORY

The original discovery well, Humble Oil and Refining Co. (now Exxon) No. 1 Jennings in SW SW SW Section 281S-3W, was completed in Dec. 1923. Initial production was 90 BOPD from a depth of 3,382 ft. The producing formation was Pennsylvanian Deese (Des Moines) sand. The Pennsylvanian Deese (Des Moines) sand. The field developed slowly over the next 6 years because wells were mostly small-volume producers of low gravity crude.

The economic crash of 1929, the depression of the 1930's and the war years of the early 1940's kept most activity at a very slow pace.

In 1945 and 1946 activity in the general area was renewed. In Aug. 1947 Stanolind Oil and Gas Co. (now Amoco) completed the No. 1 Sims, NE NE SE Section 2-1S-4W, as the Springer sand discovery. Initial production was 118 bbl of 28.9 gravity oil/day from a depth of approximately 4,800 ft. Named for the discovery well, this Sims sand was the objective in rapid development during the next 5 years. Much of the area was drilled on the density of one well per 10 acres. During this period of development, per 10 acres. During this period of development, additional Deese and Springer sands also were discovered to be productive and were developed. Stratigraphically the oldest and deepest production developed during this period was production developed during this period was from the Springer Goodwin sand below the Sims zone.

During the 15 years that followed Springer and lower Deese development activity was limited to drilling a few edge and infill wells plus commencement of several secondary recovery programs. programs.

STRUCTURE

The structural configuration on top of the Springer Sims sand is an elongated dome trending northwest-southeast (Fig. 2). The anticline is contoured without showing any faulting. Several faults can be identified. However, it is felt the anticlinal trend can be seen better if the faults are now shown. In excess of 1,200 ft of closure can be seen on this Sims structure map. Both deeper and shallower zones show the same basic anticlinal structure.

Two wells near the crest of the anticline penetrated the Mississippian False Caney: the penetrated the Mississippian False Caney: the Amoco No. 1 Sims Springer sand discovery, mentioned previously, and the Amerada No. 10 Hanson, SW NW SW Section 12-1S-4W.
