Flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. Usually, a correct description of the lateral variations of reservoir is associated with uncertainties. From this point of view, the well data alone does not cover reservoir properties. Because of large well distances, it is difficult to build the model of a heterogenic reservoir, but ...
Simulation is common practice for surgeon training in particular for robotic surgery. This paper introduces further relevant applications of simulation that improve patient safety. Therefore, the design of a modular simulator for minimally invasive robotic surgery is presented. The authors introduce a classification of hierarchical levels of modeling details for the three aspects Application, S...
residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. in this study experimental tests in a glass micromodel w...
this study is focused on developing an integrated optimization-simulation based genetic algorithm model (iosga) to develop the operational policies for a multi-purpose reservoir system. the objective function of the optimization model is considered to be a linear function of reliability (rel), resiliency (res), and vulnerability (vul) of the river-reservoir system. genetic algorithm (ga) is emp...
This paper uses hybrid simulation to evaluate the impact of a whiteboard on the workflow of an A&E department. Hybrid simulation in this context is defined as the integrated use of discrete event simulation and system dynamics; we illustrate how discrete event simulation and system dynamics, by themselves, are incapable of meeting the objective. “Parsimonious” and “divide and conquer” principle...
The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...
Purpose – The purpose of this paper is to provide a framework for analysing and modelling detailed workflow of image-guided interventions to facilitate simulation and the re-engineering process for the development of new procedures in multi-modal imaging environments. Design/methodology/approach – The methodology presented includes a literature review on workflow simulation in surgery, focussin...
Reservoir sedimentation is an unavoidable problem which has unsuitable effects on reservoirs such as decreasing of reservoir useful volume, decreasing of dam stability, unsuitable operation of operational gates and penstocks and decreasing of flood control volume. The minimization of reservoir sedimentation is a nonlinear and constrained optimization problem. Constrains imposed include reservoi...
A considerable effort has been made in the literature for quality assurance (QA) and checking (QC) of petrophysical log data computation reservoir rock property parameters. Well plays an integral role building a physics model quantitative interpretation (QI) work. poor-quality may lead to significant financial HSSE implications by drilling wells undesired locations. Historically, variety techni...
Crystallization trials at the Division of Structural Biology in Oxford are now almost exclusively carried out using a high-throughput workflow implemented in the Oxford Protein Production Facility. Initial crystallization screening is based on nanolitre-scale sitting-drop vapour-diffusion experiments (typically 100 nl of protein plus 100 nl of reservoir solution per droplet) which use standard ...
