The current API accepted method of rod string design entails the use of the Goodman Diagram. The method of designing the rod string is to determine the minimum and maximum polished rod loads and then, utilizing the Goodman Diagram, find a suitable strength rod based on its minimum ultimate tensile strength. By applying this existing method, lower rod sections are often overstressed. In the API committee's work on modifying the Goodman Diagram, it was concluded that sucker rods should not be placed in compression as their performance in compression is not predictable. In order to account for this lower section of rods in compression, a technique was developed in which, when used with the improved sucker rod design steps, would yield approx. the same rod loadings as indicated by an actual survey.
