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）

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
