Abstract
The need of oilfield operators to verify that wells are being produced at their optimum capacity and in a cost effective manner is always present. To reduce operating costs, increase oil production and increase net income requires an integrated analysis of the pumping system including the performance and interaction of all the elements: the prime mover, surface equipment, well bore equipment, down hole pump, down hole gas separator and the reservoir. This analysis is to be made based on data obtained at the surface without entering the well bore and must yield an accurate representation of the conditions that exist on the surface, within the well bore and within the reservoir. Examples of rod pumped wells, ESP pumped wells, PC pumped wells and other well analyses are presented.
