Recently, there are increasing interests in chemical enhanced oil recovery (EOR) especially
surfactant‐polymer (SP) flooding. Although alkali‐surfactant‐polymer (ASP) flooding can …

In recent years, chemical flooding has become significant in oilfield development. As its
scope of application gets wider, choosing the proper chemical agent becomes an issue for …

The polymeric surfactant can be used as an efficient agent for enhanced oil recovery (EOR)
because of its large bulk viscosity and good interfacial activity. However, there is a sparse …

Chemical enhanced oil recovery (EOR) leads to substantial incremental costs over
waterflooding of oil reservoirs. Reservoirs containing oil with a high total acid number (TAN) …

Since August 2018, a polymer flooding field pilot has been underway in an unconsolidated
heavy oil reservoir on the Alaska North Slope (ANS). Previously, a reservoir simulation …

Alkali polymer (AP) flooding is a promising enhanced oil recovery (EOR) method to increase
oil recovery from reactive oils. It is essential to carefully select the alkali and polymer type …

Recently, there are increasing interest on polymer flooding due to its high enhanced oil
recovery (10%-20% OOIP in field tests in Daqing) and much lower cost compared to …

Various polyacrylamide polymers have been successfully applied in chemical enhanced oil
recovery (EOR) projects. These polymers are characterized by high molecular weights …

Hydrocarbon (re‐) development projects need to be evaluated under uncertainty.
Forecasting oil and gas production needs to capture the ranges of the multitude of uncertain …

A polymer pilot in the 8th Torton Horizon (8 TH) Reservoir in Austria showed promising
results. The utility factors were 1.8 kg of polymer injected per incremental bbl of oil produced …
