Reserves to production ratio:
~75 years
1. Project Overview
General Information
Capture
source:
50,000 t/a of CO2 from gasification facilities of the Yulin Coal
Chemical Co., Yulin City, since 2012
360,000 t/a CO2 from gasification facilities of the Yulin Energy
Chemical Co., 100 KM southwest of Yulin City (planning)
Type: Pre-combustion (gasification)
Method: Absorption physical solvent-based process - Recti sol
Transportation
Tanker trucks + Pipeline(Planning)
Yulin City to Jingbian injection site: 140KM
Jingbian Industrial Park to Jingbian Injection site: 42KM
Storage
Site:
Primary injection site is the Jingbian oilfield of the Yanchang oil
field
Additional test volumes have been injected into the Wuqi oilfield
Xingzichuan oilfield (planning, 105KM)
Purpose: EOR
Formation and Depth: Yanchang Formation in Triassic for Jingbian
CO2 injection site ; 1,500 to 2,200 below the surface
General Information
CO2 Source-18 Coal Chemical
plants
- 25 Coal-fired
power plants
Yanchang
Oilfield Shaanxi Province
INTERNATIONAL RECOGNITION
This project was noted as a
cooperation project in the US-China
Joint Presidential Statement on
Climate Change in September
2015. -------The two countries have
identified the project site in Yan’An-
Yulin, Shan’xi Province, China,
operated by Shan’xi Yanchang
Petroleum.

HISTORICAL REVIEW
2009• Chuankou oilfield No.104 well group CO2-EOR pilot test
2012
• 50,000 t/a of CO2 from gasification facilities of the Yulin Coal Chemical Co.,
• Jingbian Qiao-Jia-Wa oilfield CO2-EOR pilot test
2013• Sino-Australian International Cooperation Demonstration Project
2014• Wuqi oilfield CO2-EOR pilot test
2016
• CCS demonstration and new generation technology research and development
• 2nd phase of Sino US International Cooperation Demonstration Project
1. Low cost CO2 capture technology in coal chemical
industry• 2012, the 50000 tons p.a. CO2 capture - Yulin Coal-chemical Company by
rectisol technology
• High concentration CO2 Capture cost: 25USD/ton
• Low concentration CO2 Capture: developed the industrialization process
package and built the pilot plant.
Main Tasks
2. CO2-EOR experiment evaluation system• Miscibility pressure between CO2 - crude oil
• Phase change of CO2- crude oil
• The influence of CO2 on reservoir
• Efficiency influencing factors of CO2-EOR
• CO2 Sealing system
Main Tasks
3. CO2 fracturing technology • Ultra-low density proppant without thickening and dry carbon dioxide
fracturing has been successfully implemented in Yanchang 4 shale
gas exploration area of continental shale gas field
Main Tasks
4. Injection-production string design and anticorrosion
technology• Optimize the ordinary carbon steel and corrosion inhibit or matching
technology and its application effect is well
Main Tasks
Injection systemProduction system
5. CO2 geologic sequestration capacity evaluation
system• To evaluate the CO2 sequestration potential of the extended ultra-low
permeability reservoir, the effective sealing capacity of CO2 in the
Yanchang oilfield is calculated to be about 400M tones
Main Tasks
6. CO2 –EOR safety monitoring system• subsurface -surface-aboveground
• CO2 geologic sequestration safety warning system
Main Tasks
ACHIEVEMENTS
1. Qiao-Jia-Wa Pilot
Two pilot test area with 10 injection gas wells had been built, cumulative
injection of 66200t , and show a good oil displacement effect, the dynamic
storage reach to 66200 tons.
ACHIEVEMENTS
2. Wuqi Pilot: 5 injection wells ,14 production wells, cumulative injection
8800t CO2, daily oil production improved from 2.22 t to 2.53 t, increased oil
production 900t.
ACHIEVEMENTS
3. New Build (for the 0.36 Mtpa facility of Yulin Energy Chemical Co., ): The
feasibility study report has been completed and planned to be completed
and put into operation in 2018.
Reserves to production ratio:
~75 years
3. Project prospect
General Objective
- Strive to build China's first megaton CCS flagship
project
- Form a comprehensive technology and standards
of coal chemical industry CO2 capture/EOR and
storage
- Create a professional team of carbon capture,
transportation, storage and monitoring
- Drive oil exploration technology and CCS business
model to provide the experience for low carbon
development in other areas of China .
General Objective
- Strive to build China's first megaton CCUS flagship
project
Short-term goal
Middle-term goal
Long-term goal
• To built 0.36 MPA integrated CCS demonstration areabefore 2018
• To built 1MPAintegrated CCS demonstration project before 2020
• To built 4 MPA integrated CCS demonstration base before 2030
