Determining the modified derivative in pressure analysis

Author

Scott Michael Frailey

Abstract

"The derivative type of curve technique of Bourdet for analyzing pressure tests requires calculating the derivative of the storage plot. Four numerical methods are used to evaluate the derivative: a five-point formula, Richardson's Extrapolation, a parabolic fit, and a central difference procedure. The parabolic fit and the central difference technique are good methods of determining the derivative. The effects of logarithmic s pacing of the data, using a central difference method, are studied. An investigation of the second derivative and the integral is conducted"-- Abstract, p. ii
