Although it has received very little publicity, Shelder field, discovered in the early 1930s, should be studied by all geologists and geophysicists because it represents clearly the link between the old oil-finding method and the new or modern exploration technique. Many recently developed exploratory tools first were introduced experimentally at Shelder field. In chronological summary, the successful culmination of the well-coordinated efforts of the Surface Party, Geiger Counter, Torsion Balance, Magnetometer, Seismograph, and Core Drill coverage is described. The productive history of this type of reservoir is demonstrated graphically, and a brief review of its economic significance is presented.

An amazing similarity between the discovery, development, and performance of Shelder field and many fields throughout the world will be noted.
