Whereas these equations can be simplified for the flow of (compressible) fluids, and idealized solutions exist in terms of Fourier series for linear flow and Bessel functions for radial flow, the flow of compressible gases requires computer solutions, read approximations. An analysis of computer solutions indicates, fortuitously, that the unsteady-state behavior can be reproduced by steady-state density or pressure profiles at successive times. This will demark draw down and the transition to long-term depletion for reservoirs with closed outer boundaries.
As an alternative, unsteady-state flow may be presented in terms of volume and surface integrals, and the methodology is fully developed with examples furnished. Among other things, permeability and reserves can be estimated from well flow tests.
The foregoing leads to an examination of boundary conditions and degrees of freedom and raises arguments that the classical partial differential equations of mathematical physics may not be allowable representations.
For so-called open petroleum reservoirs where say water-drive exists, the simplifications based on successive steady-state profiles provide a useful means of representation, which is detailed in the form of material balances.
Unsteady-State Fluid Flow provides:
• empirical and classical methods for correlating and predicting the unsteady-state behavior of petroleum reservoirs
• analysis of unsteady-state behavior, both in terms of the classical partial differential equations, and in terms of volume and surface integrals
• simplifications based on successive steady-state profiles which permit application to the depletion of both closed reservoirs and open reservoirs, and serves to distinguish drawdown, transition and long-term depletion performance.
Cancer and the Search for Selective Biochemical Inhibitors, Second Edition delineates the underlying biochemical principles for alternative cancer therapies. Completely revised and updated, this edition includes coverage of the link between concepts and practices of alternative and conventional medicine. The author examines anticancer plant substances and other alternatives such as Vitamin C, essiac tea, shark cartilage, and cat’s claw. The text also addresses the problem of determining selective and non-toxic enzyme inhibitors for cancer cell metabolic pathways.
While an increased number of allopathic professionals are in tune with alternative therapies, the integration of the two factions is far from the norm. Keeping the same format that made its predecessor a benchmark text, this book compares complementary, alternative, and integrative treatments with chemotherapy and other more traditional treatments.
