"Ratio of the theoretical drawdown in a well divided by the actual drawdown obtained from well completion test data. The theoretical drawdown is determined from discharge drawdown data. Excess drawdown may
be influenced by the factors of design and construction of the production well." (United Nations Publications, 2013)
