... test analysis without type curve matching is also developed for the analysis of pressure transient data for non-newtonian fluid. Mathematical Model The following assumptions are made in deriving the mathematical formulae. The fluid is isothermal, single-phase and slightly compressible...

... treatments. In all these applications, Newtonian and non-Newtonian fluids are widely used. Therefore the knowledge of annular flow performance of these fluids becomes important for planning and design of well-bore hydraulics. Existing knowledge about the behavior of non-Newtonian fluids in annulus is very...
