The Qilu-Shengli Oilfield CCUS will reduce carbon emissions by 1 million tons

per year

China Petroleum & Chemical Corporation (HKG: 0386, "Sinopec") has completed the

construction of China's first megaton carbon capture, utilization and storage

(CCUS) project, the Qilu-Shengli Oilfield CCUS (the "Project") on January 29,

which will reduce carbon emission by 1 million tons per year, the equivalent of

planting nearly 9 million trees and shutting down 600,000 economy cars.

As China's largest full industrial chain CCUS demonstration base and industry

benchmark, the Project is estimated to increase the oil production by 2.965

million tons in the next 15 years. It's of great significance to China's scaled

development of CCUS and building an "artificial carbon cycle" model to increase

China's carbon emissions reduction capabilities as the country advances to

achieve the "dual carbon" goals of reaching peak carbon emissions by 2030 and

carbon neutrality by 2060.

The construction of the Project was initiated in July, 2021 and is consisted of

two parts – Sinopec Qilu's carbon dioxide capture and Shengli Oilfield's carbon

dioxide displacement and storage. The carbon dioxide captured by Sinopec Qilu

will be transported to Shengli Oilfield for further displacement and storage

via green transport mode, achieving an integrated application of carbon

capture, displacement and storage to seal the carbon dioxide underground and

drive the oil out – turning the waste into treasure.

Sinopec Qilu has newly constructed a liquid carbon dioxide recovery and

utilization unit with a capacity of 1 million tons per year, which includes

compression unit, refrigeration unit, liquefaction refining unit and supporting

facilities to recover carbon dioxide from the tail gas of coal-to-hydrogen

plant with a purification rate of over 99 percent.

Meanwhile, Shengli Oilfield is applying the principle of supercritical carbon

dioxide's easy miscibility with crude oil to build 10 unattended gas injection

stations in Zhenglizhuang Oilfield to inject carbon dioxide into the 73 wells

nearby to increase crude oil fluidity and improve oil recovery while adopting a

closed pipeline transportation of oil and gas to further enhance carbon dioxide

sequestration rate.

Taking an early start of CCUS R&D and construction, Sinopec has developed its

own CCUS technology system that has achieved good results in improving crude

oil recovery and reducing carbon emissions, and some of the capture

technologies is in leading position domestically and advanced level in the

world.

Sinopec's low partial pressure carbon dioxide capture technology has been

successfully applied in more than 50 units of devices across 16 provinces and

cities in China, capturing more than 200,000 tons of carbon dioxide every year.

The company has tackled multiple key technological problems. By actively

conducting mineral field tests in the East China and Shengli oilfields and

exploring the development mode of high-pressure miscible flooding of carbon

dioxide, Sinopec has effectively solved the problem of difficult water inject

and oil well production in reservoirs of ultra-low permeability, proposed the

innovative "throughput displacement coordination" carbon dioxide injection

development mode to carry out efficient development of sealed small block

reservoirs. Sinopec has also built China's first exhaust gas displacement,

cyclic utilization and storage base of high water-cut oil reservoir industrial

refinery in Sinopec Zhongyuan Oilfield.

Backed by systematic investigation of China's large-scale carbon dioxide

emission sources, Sinopec has researched and drafted the CCUS potential

evaluation method and established the Sinopec source & sink database. To date,

Sinopec has implemented 36 carbon dioxide flooding projects.

Sinopec is looking to advance the constructions and realize the industrialized

development of CCUS. Sinopec will build a CCUS R&D center to focus on the

cutting-edge technological breakthroughs including the integration of CCUS with

new energy, hydrogen energy and biomass energy. The company will advance the

technology applications such as the carbon dioxide production of high-value

chemicals and carbon dioxide mineralization and utilization to make

breakthroughs in the core technologies and solving the equipment bottlenecks in

carbon capture, transportation, utilization and storage.

With the goal of building a carbon dioxide technological innovation system of

"technology development-construction project demonstration and

industrialization," Sinopec will extend the clean carbon sequestration

industrial chain and build the foundation for carbon emission reduction

technology innovation.

Between 2021 and 2025, Sinopec will build another megaton CCUS demonstration

project in partnership with Sinopec Nanjing Chemical Industries Co., Ltd. in

its affiliated Sinopec East China oil and gas fields and Sinopec Jiangsu

Oilfield to achieve the industrialized development of CCUS and widen the

prospects as China advances to achieve carbon peak and carbon neutrality.
