CORE FLOOD TESTS OF IN-SITU CO_2 GENERATION TECHNOLOGY

摘要

In-situ CO_2 generation technique (ISCGT) is designed to address CO_2 flooding method's shortcomings and makes CO_2 flood method economical in the places where CO_2 flooding is not feasible. The results of core-flood tests of in-situ CO_2 generation technique are presented in this paper. The experiments were conducted to define effect of surfactants on recovery efficiency. The results demonstrated obvious advantages of the foamy system over the brine solution in order to achieve higher sweep efficiency and recovery coefficient.
