Abstract
Production logging is used to evaluate wells production performance. Interpretation of production log data provides velocity profile and contribution of each zone on total production. In multi-phase flow conditions, production log interpretation can be challenging since producing fluids do not have similar densities and travel with different speed depending on fluids properties and wellbore deviation. Production log interpretation in multi-phase producing wells requires identifying downhole flow regimes and determining velocity profile for each phase. There are different flow regimes and velocity models available, which are being used in production log interpretation to determine wells flow...

Abstract
In this paper the effects of the first reservoir filling on rockfill dams were studied numerically. To simulate the problem a simplified coupled formulation based on Biot's theory associated with unsaturated soils was presented. The finite element method was applied to the governing equations for the spatial discretization, followed by a generalized Newmark scheme used for the time domain discretization. The three effects of reservoir filling, collapse settlement produced by wetting the rockfill, water load on the dam body and buoyancy in the upstream shell were introduced. The nature of collapse settlement and how to numerically capture that by using the proper constitutive model is...
