... Abstract Because flow regimes in highly deviated and horizontal wells are quite different from those of vertical wells, velocity and hold up distribution are required for accurate flow rate and fluid entry determinations in multiphase flow. Production logging in horizontal wells can...

.... The vertical radial flow regime is seldom visible and masked by wellbore storage effects. Interestingly, what is observed however, is a plateau (or sometimes valley) caused by the dual permeability effect followed by a transition to horizontal radial flow regime. This may be explained as a combined effect...
