Evaluation System of Gas Injection Experiment for EOR

Abstract

Abstract: There are big differences between gas injection and water flooding or other displacement process. In recent years, with discovery of more natural gas or gas snows, more and more oilfields have started to probe feasibilities of using gas injection for EOR. However, few literatures about systematic evaluation and related exploration that are applied for oilfield development are published at present. According to many-year studying experiences and related reports at home and abroad, this paper briefly presents the purposes of gas injection experiment and relevant researches, followed by making analysis of various lab contents in different oilfields and injected media. These can be as a guide for considerations of lab experiment contents and research projects as required for field gas injection project planning and evaluation.

Key words: gas injection, EOR, experiment, evaluation
