Since the day of its inception, artificial lifting of crude oil has confronted producers with many and varied problems. In the early days of oil production a special type sucker, or wooden branch, fitted with iron connections, was used in pumping operations. Many shallow water wells use similar equipment even today. Failures in this type of sucker rod invariably resulted from rotting, swelling, unscrewing of connections and splitting in the bradded areas.
