Abstract: Influenced by gradual global economic resumption and oil price hike, international oil majors saw a series of characteristics in their business operation in the first half of 2017, such as stable growth in oil and gas production, fall of crude processing amount, dramatic growth in business performance, remarkable enhancement of upstream profit-making ability with downstream business performance becoming divided, continual slide in capital expenditure, “downstream rising while upstream declining” in investment structure on a short-term basis, more importance attached to short-term highreturns projects, business cash flow rising substantially, and free cash flow turning into positive from negative. This article analyzes the strategic orientations adjusted by five international petroleum majors in recent years. They have focused on their advantageous areas for centralization of the assets, converting into “specialized type” from “multi-element type”. They are also in the transition from “oil and gas companies” to “gas and oil companies” to increase investment into natural gas business and from “fuel type” to “fuel type + raw material type” oil refining and chemical companies to optimize refinery assets and accelerate chemical business development. They held different opinions on the future of new energy business. International petroleum majors have adopted a series of strategic measures, such as actively adjusting their strategies, making efforts for conversion of assets and business and focusing on the advantageous areas. Those measures have played an active role in maintaining business stability and competitive position, seeking sustainable development and making response to energy revolution at the time of low oil prices.
