(Part IV Due Diligence Report) 1. Project Overview The proposed WB-financed CBM development and utilization demonstration project of Shanxi Energy CBM Investment Holding Co., Ltd. relates to the pipeline from Zheng 6 Station to the Central Treatment Plant, the CBM Central Treatment Plant in Qinshui Basin and the Qinshui Basin CBM Development Project with an Annual Capacity of 500 million m3, to be constructed by North China Oilfield Branch of PetroChina Company Limited. See Table1-1-1 for the relevant geographical location of the proposed WB-financed CBM development and utilization demonstration project of Shanxi Energy CBM Investment Controlling Co., Ltd. 1.1 Pipeline from Zheng 6 Station to Central Treatment Plant The pipeline will be laid southeastward, along Provincial Highway S331, from Zheng-6 Gas-collecting Station, passing by Zhengzhuang Town, Zheng-5 Gas-collecting Station, Pigging Stations, Xiaoquangou, etc., arriving nearby Beizhai River; eastward along Provincial Highway, passing by Zhangjiayao, Qianzhuang, Xiaoyueyang; northward along the trunk line valve chamber, Changjiazhuang and Jinfeng, arriving at the Central Processing Plant, with a total length of 20km. See Table 1-1 for the project components. Table 1-1-1 Composition of Pipeline from Zheng 6 Station to Central Treatment Plant Item Engineering volume Trunk road 508×20km Passing through highway at 7 sites Major engineering volume Passing through river at 4 sites Passing through gully at 7 sites Accompanying road (km) 4.4 1.2 CBM Central Treatment Plant in Qinshui Basin The scale of the Central Treatment Plant is 30×108m3/a (scale of Phase I: 10×108m3/a). During Phase I, 2 sets of filter separator (total scale: 6 sets), 1 set of TEG dehydration plant (total scale: 3 sets), 4 sets of CBM compressor unit (total scale: 8 sets) and other auxiliary facilities including blank nitriding station, 110kv transformer substation, flare and venting system, heat supply system, water supply and drainage system and fire fighting system, will be installed. 1 Coal Industry Taiyuan Design & Research Institute guo huan ping zheng jia zi No.1303 EIA Report of Proposed WB Financed CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part IV Due Diligence Report) Located at about 700m to the northwest of Jinfeng Village, Qinshui County, the Central Treatment Plant mainly receives the CBM produced by PetroChina from Fanzhuang Block and that produced by such enterprises as Zhonglianmei and Jinmei Group from the surrounding areas in Qinshui Basion. The CBM in the various blocks of Qinshui Basin first enters from the gas-collecting station, through the pipeline, into the gas distributing and pigging system, which is responsible for accepting the tube cleaner during the pigging operation; then enters the filter separator, which functions to separate gas with liquid from the virgin gas; then enters the pressurizer for pressurization, increasing the pressure from 0.9Mpa to 6.0Mpa; then enters the TEG dehydration plant for ensuring the transmission water dew point; finally enters West-to-East gas transmission pipeline after metering. 1.3 Qinshui Basin CBM Development Project with a Capacity of 500 Million m3 per Annum (Fanzhuang Block) Pilot CBM development in central Fangzhuang Block will be conducted with multilateral directional horizontal drilling method and that in the northern and southern parts of the Block will be conducted with vertical well and cluster well pressurization and hydrofracturing method. The vertical well and cluster well CBM development in the northern and southern parts will be divided into two stages: development with the first batch of wells and development of scale. A total of 760 CBM wells and an effective number of 685 wells will be deployed in the first batch well group CBM development area and the scale development area in the southern and northern parts. See Table 1-3-1 for the project composition and project description. Table 1-3-1: Project Composition and Project Description. Project name: Qinshui Basin CBM Development Project with a Capacity of 500 Million m3 per Annum Scale Gas Gas output Gas collecting station producing well 685 wells for 5.0×108m3/a 7 stations Phase I 603 wells for Phase II Main work Gas well, gas collecting station, gas extraction pipeline (431km), gas collecting pipeline (52km) 2 Coal Industry Taiyuan Design & Research Institute guo huan ping zheng jia zi No.1303 EIA Report of Proposed WB Financed CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd.
