U.S. shows shale technology to the world; foreigners learn techniques, but have long way to go
Oil companies from China, Norway, Japan and other nations are investing billions of dollars in U.S. shale projects so they can learn how to extract oil and gas from bedrock and use those technologies to tap into the large and mostly undeveloped shale deposits outside the U.S.
China’s Sinochem Group petrochemical company was the latest to buy into a partnership with American company Pioneer Natural Resources, paying $1.7 billion for a stake in the Wolfcamp shale play in West Texas. That January transaction is under review in Washington for compliance with national security laws.
About one-fifth of the more than $134 billion in U.S. shale investment since 2008 has come from joint ventures involving foreign companies hoping to tap into and learn from the U.S. shale boom, according to the U.S. Energy Information Administration.
China has a particular interest in acquiring shale drilling technologies because it possesses nearly one-fifth of the world’s total estimated reserves of shale oil and gas, and it has barely begun to exploit those resources. China has grown increasingly dependent on imports of oil in the past decade and would like to use its own clean-burning gas to heat homes and fuel factories and power plants, but the emerging Asian giant lacks the expertise and other key assets needed to do so.
CNOOC’s U.S. partner, Oklahoma-based Chesapeake Energy Corp., is a pioneer in the shale industry that ran up big debts from drilling projects in recent years and welcomed the $2.6 billion infusion of cash from China. CNOOC Chairman Fu Chengyu, citing Chesapeake’s leading role in shale development, predicted “substantial benefits to both parties” when he signed the deals.
Opposition in Congress killed CNOOC’s highly publicized attempt to buy out American oil company Unocal Corp. in 2005, but the U.S. government quietly approved the CNOOC and Sinopec shale investments. Since 2009, the U.S. has had an agreement with China to share technology and cooperate in the development of shale oil and gas through joint ventures between U.S. and Chinese firms.
“China is a newcomer to the shale gas industry,” said David Xu, an analyst at KPMG International. “Over time, it could become one of the world’s largest producers” if it learns the technology and resolves numerous obstacles to development.
China has the world’s largest estimated reserves of shale gas, according to the U.S. energy agency, but they are not as easily accessible as the unconventional gas in the U.S. because of key geological differences.
Much of the Chinese gas lies in mountainous regions such as Sichuan that are riddled with fault lines. This month, one of the area’s frequent earthquakes created major difficulties for drilling and transporting gas. Moreover, much of China’s shale gas is buried twice as deep as the gas in the U.S. and may contain contaminants such as hydrogen sulfide, a gas that can be lethal.
“Techniques used in the U.S. may not be appropriate at these sites,” said Mr. Xu, so even after learning through their joint ventures in the U.S., Chinese oil companies likely will have to develop techniques to tap into their own reserves. The Chinese firms are choosing U.S. partners with shale drilling experience in their attempts to make headway in China.
Another problem is that some of China’s biggest shale deposits are in western regions where large amounts of water are not available for the water-intensive hydraulic fracturing drilling process used to free up oil and gas trapped in the bedrock. Shale developers in the Sichuan region in the center of China have plenty of water available, but they would have to compete with farmers for use of the water in a country where agriculture remains a primary occupation.
Another big difference is that much of the shale in China is mixed with clay — rather than brittle bedrock in the U.S. — which makes the fracking process more difficult, Mr. Xu said. Thus techniques learned in the U.S. likely would have to be modified to be applied in China.
On top of the multiple geological obstacles, China also has many legal and bureaucratic hurdles. Notably, the state controls the biggest oil companies as well as the price of natural gas, so there is little opportunity for the kind of innovation coming from small firms that pioneered U.S. shale development, and no guarantee that once developers go to the expense of extracting the oil and gas, they would be able to make a profit or even cover their costs.
