History matching is an inverse problem of partial differential equation on mathematics. We adopt the constrained non-linear optimization to handle this problem, defining the objective function as the weighted square sum of differences between the wells simulation values and the corresponding observation values. We develop an optimization computing program that include Zoutendijk feasible direct...
Background: In the context of the recent Greek economic crisis and its detrimental impact on healthcare system as well as the complete absence of a mechanism to map and plan human resources, a need for rethinking healthcare workforce management at a national level was emerged. Objectives: The aim of the study was to identify factors that influence the current and future demand for and supply of...
To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a sequential Monte Carlo implementation of the Kalman filter: the Ensemble Kalman Filter (EnKF). The EnKF not only estimate uncertain parameters but also provide a recursive estimat...
