Oil curve analysis

The conventional analysis of production decline curves for oil or gas production consists of plotting the log of flow rate versus time on semilog paper. In cases for a decline in rate of production, the data are extrapolated into the future to provide an estimate of expected production and reserves. Decline curve analysis (DCA) is a graphical procedure used for analyzing declining production rates and forecasting future performance of oil and gas wells. Oil and gas production rates decline as a function of time; loss of reservoir pressure, or changing relative volumes of the produced fluids, are usually the cause. Decline curve analysis (DCA) is used to predict the future production of oil and gas, and it has been widely used since 1945. Arnold and Anderson (1908) presented the first mathematical model of DCA. Cutler (1924) also used the log-log paper to obtain a straight line for hyperbolic decline, so the curve shifted horizontally. Background for Traditional Analysis Decline curve analysis is a graphical procedure used for analyzing declining production rates and forecasting future performance of oil and gas wells. A curve fit of past production performance is done using certain standard curves. This curve fit is then extrapolated to predict potential future performance.

Quench oil characterization is readily performed by measuring a series of physical properties including: viscosity, water content, neutralization number, precipitation number and flash point (Table 1). In addition to physical property characterization procedures, cooling curve analysis should also be performed when needed.
