... floodings. Emulsion stability of produced liquid from strong alkaline ASP flooding was stronger than that from weak alkaline ASP flooding. The special de-emulsifier and more complicated liquid treatment process were used in strong alkaline ASP flooding field tests. The cost was much higher than that of weak...

... on reservoir souring is often underestimated, as is the effect they can have upon standard production chemicals such as scale and corrosion inhibitors. The following paper discusses the oil in water and water in oil emulsion issues during an alkaline surfactant polymer flooding pilot in Asia. Upstream...

..., investigates the use of a new and unique CO 2 -foam (emulsion) to control CO 2 mobility and also as a conformance control technique in heterogeneous reservoirs with high permeability contrast within carbonate rocks. The new CO 2 -emulsion system consists of 50-70 vol% supercritical CO 2 , 50-30 vol% of water...

... Abstract The contribution of alkaline/Surfactant/Polymer to the stability of produced crude oil emulsions is neither fully understood nor thoroughly investigated although there have been reports from previous projects that implicate risk produced water treatment. This study focuses on water...

... are generic to cEOR development, such as the heterogeneity, chemical effectiveness, emulsion, production of sales specification oil, etc. However, there are certain risks and uncertainties that are typical for this particular field, such as fractured injection, offshore environment, large secondary gas cap...

... of processing the produced emulsion from polymer flood lags behind. The polymer in the injection fluid, which alters its physical and chemical behaviors, ultimately breaks out with the produced emulsion and changes its physical and chemical characteristics. This leads to tighter emulsions, increased produced...

... Abstract Oil production is generally a complicated multi-phase flow inside pipelines, with possible W/O emulsions present with other usual phases such as free water and free oil. The water-in-oil (W/O) emulsions formed can present significant hurdles in production facilities for pumping fluids...

... Abstract On the basis of analysis of the main reasons for poor oil recovery of heavy oil reservoir by water flooding and according to the mechanism of the enhancing oil recovery, a chemical agent, which is composed of nonionic surfactants, anionic surfactants and emulsion stabilizers, can adapt...
