A method to analyze well work efficiency from consolidated data

Authors: V.A. Pavlov (Rosneft Oil Company OJSC)
A simple approach to visualization and comparison of workover results is presented. The results are ordered from the highest through to the lowest efficiency and presented in coordinates of cumulative expenses versus estimated cumulative oil production analogously to Lorenz curve. Besides visual comparison several quantitative measures are suggested for analysis.
