Simulations of Chemical Flooding—Comparison with Experimental Data

SPE Reservoir Simulation Symposium, 1982
ABSTRACT A compositional simulator is used to model chemical flooding. Computed results are compared to laboratory studies available in the literature. Special representations were devised to model the surface tension and phase behavior of Types II(-) and III on ternary diagrams.

A Mechanistic Integrated Geochemical and Chemical Flooding Tool for Alkaline/Surfactant/Polymer Floods

SPE Improved Oil Recovery Symposium, 2014
Abstract Mechanistic simulation of alkaline/surfactant/polymer (ASP) flooding considers chemical reactions between the alkali and the oil to form in-situ soap and reactions between the alkali and the minerals and brine. A comprehensive mechanistic modeling of such process remains a challenge, mainly due to the complicated ASP phase ...

New Scaling Criteria For Chemical Flooding Experiments

Journal of Canadian Petroleum Technology, 1990
Abstract This paper presents a set of scaling criteria for alkaline/polymer/cosurfactant flooding experiments. Numerous studies dealing with such chemical flooding experiments have been reported. However, these have been performed in unsealed models.

Evaluation of the effectiveness of chemical flooding using heterogeneous sandpack flood test

Journal of Petroleum Science and Engineering, 2007
Abstract Alkaline flooding appears to be a promising process for enhancing heavy oil recovery after primary or secondary production from those reservoirs where thermal processes are not applicable. However, due to the heterogeneity of the reservoirs, the injected chemical solutions may flow to the producing wells through the high permeable channels ...

Relevance between Emulsification Capability and Interfacial Tension of Chemical Flooding Agents

Energy & Fuels, 2018
In chemical flooding processes, in situ emulsification between oil displacing agents and crude oil has a significant effect on enhanced oil recovery. Currently, this in situ emulsification process is still little understood.

Improved Water Soluble Polymers for Chemical Flooding

SPE Nigeria Annual International Conference and Exhibition, 2018
Abstract Nanotechnology has shown enormous progress in the petroleum industry especially in the area of Enhanced Oil Recovery. However, field experience has shown that the major challenge facing polymer flooding is polymer degradation under reservoir conditions such as high temperature and high salinity.

Economics of Field Proven Chemical Flooding Technologies

SPE Symposium on Improved Oil Recovery, 2008
Abstract Chemical enhanced oil recovery technologies are field-proven methods that improve overall oil recovery. High oil prices and dropping reserves replacement has stimulated interest in these technologies, particularly for application in mature waterfloods.

Application of Artificial Intelligence for Mechanistic Modeling and Probabilistic Forecasting of Hybrid Low Salinity Chemical Flooding

Day 3 Wed, September 26, 2018, 2018
After nearly thirty years of research and development, it is now widely agreed that Low Salinity Waterflooding (LSW) provides better oil recovery than High Salinity Waterflooding (HSW).

A Chemical Theory for Linear Alkaline Flooding

Society of Petroleum Engineers Journal, 1982
Abstract A simple equilibrium chemical model is presented for continuous, linear, alkaline waterflooding of acid oils. The unique feature of the theory is that the chemistry of the acid hydrolysis to produce surfactants is included, but only for a single acid species.

Numerical Simulation Of Competing Chemical Flood Designs

SPE Symposium on Improved Methods of Oil Recovery, 1978
Abstract Two chemical flooding design philosophies:a small slug, high concentration, "soluble oil" system, anda large slug, dilute concentration, "optimal salinity" design, were investigated in pursuit of a chemical system suitable for testing pursuit of a chemical system suitable for testing in the Department of ...
