enhanced oil recovery using nitrogen injection is a commonly applied method for pressuremaintenance in conventional reservoirs. numerical simulations can be practiced for the prediction ofa reservoir performance in the course of injection process; however, a detailed simulation might takeup enormous computer processing time. in such cases, a simple statistical model may be a goodapproach to the...

In the last decade, ensemble-based methods have been widely investigated and applied for data assimilation of flow problems associated with atmospheric physics and petroleum reservoir history matching. This paper focuses entirely on the reservoir history-matching problem. Among the ensemble-based methods, the ensemble Kalman filter (EnKF) is the most popular for history-matching applications. H...

Shale reserves have become an ever-increasing component of the world’s energy map. The optimal design multi-well multi-stage fracturing (MMF) treatments is essential to economic development such resources. However, optimizing MMF a complex process. It requires geomechanical simulation, reservoir and automatic optimization. In this work, integrated workflow proposed optimize in unconventional re...

Purpose: This article presents a data-integrated simulation based method to evaluate patient-to-nurse assignments ahead of a shift. Unlike patient classification systems, which just estimate the workload, this simulation tool quantifies the workload of nurses by simulating individual nurse’s workflow for the entire shift. Design: To enable building the simulation model, the nurse workflow data ...

Predicting oil recovery efficiency of a deepwater reservoir is a challenging task. One approach to characterize a deepwater reservoir and to predict its producibility is by analyzing its depositional information. This research proposes a deposition-based stratigraphic interpretation framework for deepwater reservoir characterization. In this framework, one critical task is the identification an...

Pursuit and use of geothermal energy in the Netherlands is developing steadily. However, in order to make sound decisions, investors and insurers are requesting the probability of success of each planned geothermal project. A methodological appraisal system was developed in order to achieve a meaningful probability of success of the expected flow rate and thermal capacity. The appraisal system ...

Time variability of reservoir parameters in water flooding has an effect on oilfield development rules. Meanwhile, time variability of different reservoir macro-parameters has certain synergetic relationship with each other. Based on microscopic network simulation and reservoir numerical simulation, a new simulation method is presented, which can describe the influence of reservoir parameters' ...

This study provides insights into the experience gained from investigating thermodynamic behavior of well and reservoir fluids during acid gas injection (AGI) in a hydrocarbon field to enhance oil recovery (EOR) reduce greenhouse emissions. Unlike conventional water natural injection, AGI involves complicated phase changes physical property variations at various pressure-temperature (P-T) condi...

 To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...
