Jingbian CCS Project has being conducted by Shaanxi Yanchang Petroleum Group and Northwest University since January 2012. CO2 injection was started on September 4, 2012. There are five CO2 injection wells in Jingbian Field. Till the end of June 2016, more than 60,000 tonnes of CO2 were injected into Chang 6 reservoir group of Upper Triassic. CO2 is captured from coal chemical company and transported by truck. CO2-EOR is expected to increase oil production in low porosity and extremely low permeability reservoir where water is hard to be injected. Through CO2-EOR, the current oil recovery is closing to 10% comparing with water recovery. At the same time, we systematically evaluated the capacity of Chang 6 reservoir. Safety of caprock seal ability and possible fracture distribution are studied as well. 3D reservoir model was made and reservoir simulation was used to evaluate CO2 migration and predict the CO2 leakage risk at different CO2 injection stages. For the surface environmental monitoring, we studied the impact of CO2 concentration on soil and microorganism, murine and fish was studied so that we might find indirect indicators for CO2 leakage. Furthermore, 3D seismic baseline data was acquired in the second CCS site of Shaanxi Yanchang Petroleum Group.
