In countercurrent flow absorption columns and trickle beds, if either the liquid or gas flow is too high the column becomes flooded with the liquid. Flooding is accompanied by a dramatic increase in pressure, resulting in inefficient operation and potential damage to equipment. To optimize efficiency, however, it is desirable to operate as close to flooding as possible. This article discusses t...

The theory of risk provides a systematic approach to handling uncertainty with well-defined risk and deviation measures. As the model-based economic optimization of the water-flooding process in oil reservoirs suffers from high levels of uncertainty, the concepts from the theory of risk are highly relevant. In this paper, the main focus is to offer an asymmetric risk management, i.e., to maximi...

Recently, nano-EOR has emerged as a new frontier for improved and enhanced oil recovery (IOR & EOR). Despite their benefits, the nanoparticles tend to agglomerate at reservoir conditions which cause their detachment from the oil/water interface, and are consequently retained rather than transported through a porous medium. Dielectric nanoparticles including ZnO have been proposed to be a good r...

In this paper, the problem of flooding management using hybrid model predictive control is presented and applied to the Ebro River in Spain. The Ebro river presents flooding episodes in the city of Zaragoza during spring when snow melts in the Pyrenees. To avoid flooding in living areas, some lands outside the city are prepared to be flooded. This paper presents a control approach to determine ...

The second outlin...

Tropical Storm Debby brought severe flooding to portions of southwestern Florida during the summer of 2012. Remotely-sensed images were collected to document the flooding and test the results of Hydrologic and Hydraulic (H & H) storm water models constructed by the Southwest Florida Water Management District (SWFWMD). One image, a satellite, multi-band SPOT image was provided to the SWFWMD by t...

In this paper, the problem of flooding management at the Ebro River in Spain is presented. The Ebro river presents flooding episodes in the city of Zaragoza in spring when snow melts in the Pyrenees. To avoid flooding in living areas, some lands outside the city are prepared to be flooded. This paper presents a hybrid model predictive control approach to determine and fix the level of flooding ...

Water flooding microscopic seepage experiment is an effective method to study the microvadose mechanisms as well as the distributions of remaining oil. Throughout the experiment the quantitative description of the porous medium fluid flow parameters such as porosity, oil saturation and so forth is crucial. A quantitative analysis method is proposed via image processing, including image preproce...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...
