Comparison of Drainage Equations for the Gravity Drainage of Stratified Profiles1

  1. K. K. Watson and
  2. F. D. Whisler2

Abstract

Abstract

The output from a computer-based numerical analysis of the gravity drainage of a sand profile through an underlying impeding layer is used as the data for testing the manner in which algebraic equations are capable of describing the stratified drainage process. The comparisons indicate that no single equation is satisfactory in describing the wide range of nonlinear behavior that occurs with eight cases analyzed. However, when specific coefficients determined from a least squares analysis are used in an equation of the Jackson and Whisler type satisfactory correspondence is achieved.
