Green Dragon Gas , one of the largest independent companies involved in the production and sale of Coal Bed Methane (CBM) gas in China, has announced that the Qinshui Basin Chengzhuang Cooperative CBM Block ('GCZ Block') Overall Development Plan ('ODP') has been approved by the Consultation Center of China National Petroleum Corporation ('CNPC').


  • As of date, 114 wells have been drilled on the acreage. The development plan includes the drilling of an additional 147 production wells in 2017 & 2018. These wells will be targeting both coal seam #3 & coal seam #15.
  • Estimated gross annual production of 3.01 Bcf in 2017, with production estimated to increase to 3.23 Bcf (2.64 Bcf from existing wells and 0.59 Bcf from new wells) in 2018.
  • Upon the successful completion of the development plan, the 2016 NSAI CPR estimated current probable reserves at GCZ of 15.7 Bcf (NPV10 $116.1m) are expected to be migrated to 1P reserves, bringing total 1P reserves to 29Bcf.
  • The development cost for GCZ is budgeted to be c.$53.80 million over 2017 and 2018. CNPC will invest $28.51m in accordance with its 53% participating interest and the Company $25.28m based on its 47% of participating interest in the Block. Under the terms of the PSC, CNPC can carry the company which it has done till date in the blocks development.
  • Senior technical experts from CNPC Planning Department, CNPC Exploration & Production Branch, China Foreign Cooperation Administration Department ("CCAD"), PetroChina Huabei Oilfield and Greka Energy (International) B.V. jointly took part in the technical working sessions and overall discussions.
  • The Joint Management Committee approved the ODP on 14th April, 2017 for submission to NDRC.

Chinese State support for CBM industry

On 8 April 2017, in accordance with China's 13th Five-Year Plan, Chinese government authorities delivered a policy to facilitate expediting the State approval processes. Following the issuance of this policy, once the ODP is approved by the State Owned Enterprise, it is to be registered with the NDRC and promptly implemented, as part of this new policy.

About the Chengzhuang Block (GCZ Block)

The GCZ Block is located in the prolific Qinshui Basin with an area of 67 km², approx. 20 km south of the Greka Shizhuang South Main Block ('GSS Block'). Reservoir properties and geological settings are similar to those found in the GSS Block. There are two major laterally continuous shallow coal seams present throughout the GCZ Block, namely, coal seam #3 and #15. CBM in this area is imbedded in the coal formations at average depths, ranging from 300m to 600m. The block has been in commercial production since 2010.

The block is producing a stable cash flow, which is split in proportion to working interest between GDG (47%) and CNPC (53% - operator) since the completion of CNPC's cost recovery pool in August 2015.

As per the NSAI Reserve Report of 31 December 2016, GCZ Block has original gas in place of 275 Bcf. The Block has 14 Bcf in net 1P gas reserves, 29 Bcf in net 2P gas reserves and 51 Bcf in net 3P gas reserves with future NPV 10 of 116 MM$ in 1P, 232 MM$ in 2P and 376 MM$ in 3P.

Randeep S. Grewal, Chairman and Founder of Green Dragon Gas, commented:

'This is a significant step forward for GDG and a further realisation of our strategy of progressing our resource base through to long term production.  GCZ ODP, while only 0.44% of our total acreage, fairly represents the profit potential of Green Dragon's asset portfolio.  In this investment, $45.5million was invested between 2009-2016, during which 114 wells were drilled and on commencement of production, the costs were recovered  leading to net cash flow returned as dividends to the parent from October 2015. GDG has been carried for all development capex and cost in relation to GCZ.

'Additionally, I would like to note and welcome the continued and consistent support of the Chinese central government for CBM in China and its plans to aid the coal bed methane industry. I look forward to announcing the progress of GCZ, alongside our partners CNPC and PetroChina, as we implement  the development plan and drive our production growth.'
