Location: Jilin oil field, Songyuan, Jilin Province, China
Start Date: 2009
Size: 0.2 Mt/yr
CO2 Source: Natural gas processing plant
Storage: Jilin oil field. Transportation to onshore injection site via pipeline
Project in 2009 cost $11million.
Scale Up: The project has a larger scale phase 2 starting in 2017. This larger project would have a 0.5 Mt/Yr capacity.
In 2009 PetroChina started its Jilin CO2-EOR pilot project in 2009. It was China's first CO2-EOR project. By the end of May 8th, 2011, about 167,000 tonnes of CO2 had been successfully stored. The total oil production due to the EOR reached 119,000 tonnes. PetroChina plans to increase this project to a Phase 2, larger scale CO2-EOR by 2015. Phase 2 of the Jilin project plans to sequester 0.8-1Mt/yr with an increased oil production of 500,000 tonnes/year.
The processing of the gas is from the nearby Changchun gas field where the CO2 content is around 22.5%. The CO2 injection was around 30-40 t/day.
The project is using post-combustion capture with MEA absorption capture technology.
China has 2/3rds of its undeveloped oil in low permeability reservoirs. There is a huge market for CO2-EOR in these locations. Jilin oil field is a very large oil field with multiple thin horizons. The region was first explored in 1961 and has been operating for the last 50 years. In 2010 the Jilin Oil Field area was still producing 7.5 million tonnes of oil and gas, making it China's seventh largest oil field.
