Chemical Flooding for Enhanced Recovery
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2012Abstract Chemical flooding is an important enhancing recovery technology. Displacement mechanisms of different displacement agents were dissimilar. There were some experiments finished to research the effect of chemical flooding. After evaluation of displacement systems, recoveries of all formulas were determined and the recovery contour diagram was ...

Chemical flooding — status report
Journal of Petroleum Science and Engineering, 1989Abstract The current status of polymer flooding, surfactant flooding, and alkaline flooding is described with emphasis on the process mechanisms underlying each method. Requirements for future research and development are identified. It is concluded that polymer flooding and to a certain degree also alkaline/polymer flooding presently have the ...

Neuro-simulation modeling of chemical flooding
Journal of Petroleum Science and Engineering, 2011Abstract Chemical flooding has proved to enhance oil recovery of reservoirs considerably. Development strategies of this method are more efficient when they consider both aspects of operation (recovery factor, RF) and economics (net present value, NPV). In this study, a multi-layer perceptron (MLP) neural network is developed for modeling of chemical

IOR 1991 - 6th European Symposium on Improved Oil Recovery, 1991
Good afternoon. First, I would like to thank Odd Skontorp and all of the Organizing Committee for the opportunity to help summarize the status of chemical flooding and per'haps raise some topics for reflection and discussion.

Dykstra Parsons Water Flood Theory Adapted to Chemical Flood Modelling
SPE International Improved Oil Recovery Conference in Asia Pacific, 2005Abstract The method of Dykstra-Parsons, originally developed to model water flood performance, has been adapted to screen reservoirs for their Chemical / Polymer Flood suitability. Firstly, this paper summarises Dykstra-Parsons’ Theory alongside an automated method of tuning reservoir layer properties to [pre-chemical] water flood ...

Chemical Flooding in Stratified Reservoirs
1993An analytical model of the displacement of oil by a chemical solution from heterogeneous stratified reservoirs is constructed in this chapter. The viscous-dominated case considered in Chapter 3 is described in the greatest detail [87,159]. The quasi-two-dimensional problem has a self-similar solution, permitting Welge‘s method (Section 3.2) to be ...

A General Purpose Chemical Flood Simulator
SPE Symposium on Reservoir Simulation, 1987ABSTRACT A new advanced and versatile chemical flood simulator has been developed for modelling polymer and surfactant oil recovery processes. The simulator takes into account many important fluid properties and includes a sophisticated treatment of phase behaviour.

Public health impacts of floods and chemical contamination
Journal of Public Health, 2004Flooding accounts for about 40 per cent of all natural disasters that occur worldwide. In 2002-2003 many counties in England experienced severe floods. Floods are particularly important in public health terms as they may have multiple environmental consequences.Details of floods reported to Chemical Hazards and Poisons Division, London [CHaPD(L)] were ...
