Two Revision Methods Based on Constraints: Application to a Flooding Problem
نویسندگان
چکیده
In this paper, we are interested in geographic information revision in the framework of a flooding problem. We show how to express and how to revise this problem by using simple linear constraints. We present two revision strategies based on linear constraints resolution: the partial revision and the global revision methods. We apply these approaches on both a real-world flooding problem and random flooding instances.

Geographic Information Revision Based on Constraints
Information usually has many sources and is often incomplete and / or uncertain, this leads to many inconsistencies. Revision is the operation which consists in identifying these inconsistencies and then in removing them by changing a minimum of information. In this paper, we are interested in geographic information revision in the framework of a flooding problem. We show how to express and how...
متن کاملAn Injection Rate Optimization in a Water Flooding Case Study with an Adaptive Simulated Annealing Techniques
This paper introduces an effective production optimization and a water injection allocation method for oil reservoirs with water injection. In this method, a two-stage adaptive simulated annealing (ASA) is used. A coarse-grid model is made based on average horizon permeability at the beginning iterations of the optimization to search quickly. In the second stage, the fine-grid model is used to ...
متن کاملApplication of multi-criteria decision making to estimate the potential of flooding
Integrating a geographic information system and multi-criteria decision making methods have been lead to provide spatial multi-criteria decision making methods. In this study, the spatial potential of flooding was determined based on analytic network process and analytic hierarchy process. At first, six factors of flooding were determined as criteria. The criteria were the slope, hill-slope asp...
متن کاملApplication of Network RTK Positions and Geometric Constraints to the Problem of Attitude Determination Using the GPS Carrier Phase Measurements
Nowadays, navigation is an unavoidable fact in military and civil aerial transportations. The Global Positioning System (GPS) is commonly used for computing the orientation or attitude of a moving platform. The relative positions of the GPS antennas are computed using the GPS code and/or phase measurements. To achieve a precise attitude determination, Carrier phase observations of GPS requiring...
متن کاملA new investigation on modeling of permeability reduction during CO2 flooding processes in sandstone oil reservoirs
Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered. In this work, a modified model based on four phase black oil model (oil, water, gas, and asphaltene) was developed to account permeability reduction during CO2 flooding in cylindrical coordinates around a ...
