Definition - What does Simplex Fitting mean?
Simplex Fitting is a quick and easy optimization technique whereby one finds the best response in a multidimensional space, where the variables may be interrelated. Simplex fitting is easy to implement and can be used for simulation and mathematical modeling of the oil and gas reservoirs for complete (i.e. from reservoir to wellhead) production systems analysis for the evaluation of petroleum reservoir production performance and optimization of oil and/ or gas production.
Petropedia explains Simplex Fitting
Simplex fitting enables an oil and gas exploration and production organization to find the best response in a multidimensional space, where the variables may be interrelated. It is usually used in oil and/ or gas production optimization from the reservoir. Real-time data is collected from the oil and gas reservoirs for complete production systems analysis.
Simplex algorithms are used for the simulation and mathematical modeling of the oil and gas reservoirs. Simplex non-linear minimization method can be used to determine the coefficients of higher order fitting polynomial, in which the polynomial used to describe the correlation between the q/delta P plotting functions and the cumulative production function. Outliers are minimized in this way by forcing a polynomial fit through the data plotting function using a generalized Least Absolute Deviation merit function for the determination of the polynomial coefficients.
