In most later-developed oilfields, a plethora of information may be available to the production engineer to assist in making decisions, such as deciding which wells should be scheduled for workover operations. In many cases, the amount of information may cloud the decision making process. For example, when comparing just two wells, information such as water cut, oil production rate, gas production rate, and lift parameters as between the two wells may give mixed signals as the ranking the two wells for workover operations. The problem compounds exponentially when considering a significant number of wells and/or patterns of wells.
