Core Flood Tests of In-Situ CO₂ Generation Technology

In-situ CO₂ generation technique (ISCGT) is designed to address CO₂ flooding method’s shortcomings and makes CO₂ flood method economical in the places where CO₂ flooding is not feasible. The results of core-flood tests of in-situ CO₂ 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.
