The transient pressure during the fall-off period is highly affected by the residual leak-off and continuing after flow that could disturb formation flow regimes during the test, affecting the ability to get correct pore pressure...

... and Pedersen, 2010 ; Mattar and Anderson, 2003 ). Along with the above metioned regimes, other flow behaviors have been observed which cannot be explained using presently know flow regimes. The most common among these odd flow behaviours is the transition between transient linear flow and boundary dominated...

We provide practical criteria to identify various scenarios affecting...

.... Moreover it was shown that during build-up tests of more than 500 hours, linear flow was the dominant flow regime and therefore the final radial flow stabilization had not yet been reached. There are many studies in the literature on the design, operations, characterization and numerical modelling...
