the gas-assisted gravity drainage (gagd) process is designed and practiced based on gravitydrainage idea and uses the advantage of density difference between injected co2 and reservoir oil.in this work, one of iran western oilfields was selected as a case study and a sector model wassimulated based on its rock and fluid properties. the pressure of co2 gas injection was close to themmp of the oi...

Introduction This study provides a summary of the 2009 ERA-EDTA Registry Report, with a focus on the differences in the incidence and prevalence of haemodialysis (HD), peritoneal dialysis (PD) and renal transplantation between countries and over time. Methods For this report, 56 data sets on renal replacement therapy (RRT) from national and regional registries in 30 countries in Europe and bo...

Renal replacement therapy (RRT) has become an established component of modern critical care. Approximately 60 70% of critically ill patients with severe acute kidney injury (AKI) are treated with RRT which represents ~5% of all intensive care unit (ICU) admissions (Ostermann & Chang, 2008; Uchino et al., 2005). Thirty years ago, intermittent haemodialysis for the critically ill patient with AKI...

A remote sensing image is composed of vegetation and base rock or soil in moutain areas, which can be decomposed by the fractal model through Fourier transformation to enhance base rock or soil information. In this paper, four scene images of two types of bed rock from Anhui province are taken as a case to demonstrate the method’s validity: two scene images’ base rocks are monzonite granite whi...

Much recent work on automatic history matching and data assimilation has focused on the adjustment of simulator gridblock permeabilities and porosities. Here, we show that when production data are assimilated into reservoir models with the ensemble Kalman filter, it is relatively easy to account for uncertainty in the depths of the initial fluid contacts and provide estimates of these depths in...
