Opinions on Energy Development Strategy of China’s 13th Five-Year Plan Zhou Dadi 2016, 35(5): 1-8.  DOI: 10.3969/j.issn.1002-302x.2016.05.001 Abstract ( )   PDF (2601KB) ( )   Currently, global energy consumption is still based on fossil energy, but non-fossil energy, renewable energy in particular is under rapid development. Global fossil energy resources are generally adequate but production cost varies significantly. Energy consumption growth is slowed down thanks to the balance between the oil and gas market supply and demand. Oil prices are likely to fluctuate at low levels on a long-term basis. Following a high growth stage, China’s energy consumption now enters into an adjustment and conversion stage.The surplus of conventional energy and the hurdle for development of high-quality low-carbon energy are the main contradictions. The direction of global energy development will come under influence of the environment and climatic changes, gradually turning to non-fossil energy. The low-carbon development trend becomes clearer and clearer day by day. Energy saving and reduction of energy consumption remain as the priority area. The energy saving policies and energy efficiency technology are under rapid development. China’s energy growth rate and its total energy consumption are likely to be lower than expected during the 13th Five-Year Plan period. The priority should be continually given to energy saving under the new situation, promoting energy consumption revolution. It is necessary to share the pressure of environmental treatment and carbon emission while acceleratingenergy industrial adjustment, implement structural adjustment in the energy sector in prevention of blind investment and further adjust the investment direction, continually promote rapid development of natural gas and various kinds of non-fossil energy, and accelerate the structural transition of energy to green and low carbon directions.

Establish “Three Costs and Four Performance Zones” Model in Execution of Cost-effective Development Strategy Shi Zhongqin, Zhao Yunxian, Dong Xianbin, Ren Qi 2016, 35(5): 13-19.  DOI: 10.3969/j.issn.1002-302x.2016.05.03 Abstract ( )   PDF (2636KB) ( )   To make an active and effective response to the continuously low international oil prices, an economic operation model, called “three costs and four performance zones” model, is established on the basis of using the marginal analysis theories of micro-economics. Three kinds of cost – operational cost, service cost and total cost – are determined according to the sensitive degrees of cost to production. The evaluated targets, such as a single oil or water well, a development unit, a development block, an oil production management zone, an oil production plant, and an oilfield, are classified into four performance zones of high-effective profit-making zone, effective marginal zone, low-effective incremental zone and ineffective operational zone. With the performance divided into different levels and policies implemented for different categories, the oilfield enterprises are guided for cost-effective development so that they can prove their production and economic performance and turn their losses into profits.

It bases itself on evaluation of single-well performance, reduction of production cost as the means, and fulfillment of the high-performance development objective. The model for optimization of investment is established at the stage of new-well productivity construction to optimize investment structure and keep design of new well in connection with economic performance. At the production and development stage, the plate of “three costs and four performance zones” for risks pre-evaluation of stimulation measures is created to tighten control at the sources, avoid inefficient investment measures and control budget of high-cost well. As for conversion of development pattern, the design plan is optimized for management of production details and guarantee of high performance in operation of key projects. Based on cost-effective control over the full development cycle, the enterprise promotes its sustainable development at high quality and in high economic performance.

This paper analyzes the new trend of international oil and gas industry as well as the driving factors behind this trend. The market depression leads to higher requirements on identification of the risks for development of new overseas oil and gas projects. It also makes quantitative risk analysis and evaluation of the countries where China’s big-three oil companies were engaged in 40 overseas oil and gas projects in 2015. Of those, the countries with high risks accounted for 22.5 percent while the countries with comparatively high, medium and low risks made up for 17.5 percent, 10 percent and 50 percent respectively. Taking into account global oil and gas resources distribution characteristics and investment risks, this paper comes up with the orientation for expansion of overseas oil and gas projects, proposing to maintain the energy-supplying bases in Central Asia, enter the high-end market presence in the Middle East, establish the win-win onshore and offshore production bases in Africa, make active involvement in non-conventional energy development in Americas and strive to construct the natural gas supplying bases in the Asia-Pacific.

New Energy Business Distributed and Adjusted by International Oil Majors Yu Benshan, He Yanqing, Yang Jinhua, Li Xiaoguang 2016, 35(5): 51-56.  DOI: 10.3969/j.issn.1002-302x.2016.05.009 Abstract ( )   PDF (2647KB) ( )   The identical view is shared worldwide that energy structure should be in transition to the low-carbon and clean direction. The continual low oil prices cannot block the energy multi-element development trend. All the countries are expected to spare no efforts to promote new energy industrial development after signing of “Paris Agreement”. International oil prices continue to fluctuate at low levels while conversion of energy is under acceleration. Against the background of these two pressures, international oil majors started to review their positions, plans and deployment of energy business development and accelerate their transition towards integrated energy firms in the efforts to identify the new growth points for business performance and step up the anti-risk capacity of their companies. While keeping the oil and gas business development stable, the Chinese oil companies should focus more efforts on the new energy development trend and meet the future challenge on the basis of the multi-element strategic deployment.
