| Abstract: | The proposed work provides a new definition of the pressure derivative function [that is the [beta]- derivative function, [unable to replicate formula], which is defined as the derivative of the logarithm of pressure drop data with respect to the logarithm of time. This formulation is based on the "power-law" concept. This is not a trivial definition, but rather a definition that provides a unique characterization of "power-law" flow regimes which are uniquely defined by the [unable to replicate formula], function [that is a constant [unable to replicate formula], behavior]. The [unable to replicate formula], function represents a new application of the traditional pressure derivative function, the"power-law" differentiation method (that is computing the [unable to replicate formula], derivative) provides an accurate and consistent mechanism for computing the primary pressure derivative (that is the Cartesian derivative, [unable to replicate formula], as well as the "Bourdet" well testing derivative [that is the "semilog" derivative, [unable to replicate formulas]. The Cartesian and semilog derivatives can be extracted directly from the power-law derivative (and vice-versa) using the definition given above. |
