This article discusses development of the "Polymer flooding" module for distributed information system of oil fields development analysis. This module is designed to simulate displacement of oil using polymer injection method for 1532 Timur Imankulov et al. enhanced oil recovery and based on modern mathematical model that considers influence of salt and polymer concentrations on viscosity of in...

Any sufficiently complex system is best described (or specified) with a combination of models in multiple formalisms. To support the creation of such “hybrid models”, recent research focuses on the (syntactic and semantic) combination of formalism fragments. To implement the hybrid language’s operational semantics, the simulators of each of the formalisms are combined. Inspired by this same pri...

Upcoming organic devices like thin lm transistors or light emitting diodes require novel architectures and materials. In most cases, two main problems, namely poor carrier mobility in the bulk and elusive interface effects, are closely related due to contact dominated device behavior. A three-dimensional Kinetic Monte Carlo simulator has been developed mimicking simultaneously charge injection ...

This work considers a tool for simulating single event transients produced by ground level radiation in VDSM ICs. Fault injection procedures and a fast fault simulation algorithm for transient faults were implemented around an event driven simulator. A statistical analysis was implemented to organize data sampled from simulations. The performance evaluation of the algorithm shows that for a lar...

Modeling the injection of CO 2 and its sequestration will require simulations of a multi-well injection system in a large reservoir field. However, modeling at the injection well scale is a necessary prerequisite to reservoir scale modeling. We report on the development and application of two models: 1) a semi-analytical model (PNLCARB), and 2) a numerical model (STOMP-CO 2). PNLCARB can simula...

Underground hydrogen storage can store grid-scale energy for balancing both short-term and long-term inter-seasonal supply demand. However, there is no numerical simulator which dedicated to the design optimisation of such technology at grid scale. This study develops novel simulation capabilities GPSFLOW (General Purpose Subsurface Flow Simulator) modelling gas mixture (e.g., H2–CO2–CH4–N2) in...

Calibration of ground water transport models is often performed using results of field tracer experiments. However, little attention is usually paid to the influence, on resulting breakthrough curves, of injection conditions and well-aquifer interactions, more particularly of the influence of the possible trapping of the tracer in the injection wellbore. Recently, a new mathematical and numeric...

SWORDFISH (Simple Wormhole Routing and Fault Injection on Simulated Hardware) is a simulator to explore the design space of high-performance networks. The simulator features a high modularity and is configurable by plug-ins. The simulated network is scalable to a large number of nodes and its modules are parameterizable to model timing, delays and buffer sizes. A simple and universal method to ...

Abstract This paper presents a coupled finite element approach for modeling geomechanical effects induced by production/injection processes in petroleum reservoirs. The module developed employs coupled- reservoir analysis using CMG IMEX® as the flow simulator and program MATLAB® stress–strain simulator, two-way explicit partial coupling scheme. mechanical problems are change of effective stress...

Laboratory experiments and numerical studies have been conducted to investigate the use of a shear-thinning polymer (Xanthan gum) to improve access to low-permeability zones in heterogeneous systems. The impact of polymer concentration, fluid injection rate, and permeability contrast in the heterogeneous systems has been studied in a series of eleven two-dimensional flow-cell experiments. The S...
