Better design, study of operations and planned maintenance of subsurface equipment can often result in reduced lifting cost per barrel of oil. A suggested graphical history of pumping operations will be presented which acts as a graphical records help to readily illustrate problem wells and are also good guides for determining remedial action when necessary. Field cases using the graphical form and results of remedial work will be presented. Normal pulling cost and pump maintenance at various depths will be discussed to emphasize the large sums of depths will be discussed to emphasize the large sums of money that are being spent and the need of monthly systematic well records to determine if operational problems exist.
