EOR on site implementation
16

Abstract

All crude fields are unique. There are many EOR methods and the method choice should
be made by taking into the account the reservoir conditions, available technical capabili-
ties and production increment forecasts. There is always the best method to apply for all
circumstances. Not all possible EOR methods have the same Technical Readiness Level
(TRL). Big volume of knowledge and data should come together to make an informed
choice. This chapter outlines steps which need to be made before full EOR project is
implemented at an oil field.

16.1 Screening evaluation

The initial step before any Enhanced Oil Recovery method to a field (or more com-
monly to the specific reservoir or even oil containing strata) is to decide which oil
production enhancement method or methods are most appropriate. This is done on
the basis of reservoir and oil properties analysis so named screening step.
Screening studies are designed to assess the feasibility of using the enhanced oil
recovery method based on a limited number of reservoir and fluid properties. Those
properties are mostly regarded as critical. Screening is a comparison of the aver-
aged characteristics of the reservoir with tabulated criteria of various methods appli-
cability. The set of tabulated criteria is made on the basis of the joint international
oil industry experience.
