China’s shale gas production will likely reach 17 billion cubic meters (Bcm) in 2020, nearly double the 2017 level, as local oil companies make big progress with drilling technology and cost cutting, consultancy Wood Mackenzie said in a note on April 17.
Nearly 700 new wells will come onstream between 2018 and 2020 at three key projects—Sinopec's Fuling, and PetroChina’s Changning-Weiyuan and Zhaotong—all located in the country’s southwest, and at a total cost of $5.5 billion, Woodmac estimated.
The forecast 17 Bcm of output in 2020 falls short of Beijing’s goal of 30 Bcm, which was slashed by more than half from the government’s initial target set in 2012.
That means the world’s third gas user will need to keep its imports of LNG at elevated levels. Woodmac has separately forecast China’s LNG imports will increase by a quarter to nearly 49 million tonnes this year, from record highs in 2017.
China produced 9 Bcm of shale gas last year, or 6% of its total gas output.
“China is eager to materialise its shale gas potential to fuel its massive gasification initiative and support rising demand growth,” said Wood Mackenzie's Tingyun Yang.
Despite estimates that China is home to the world’s largest recoverable shale gas resource, its shale formations tend to be deeper, more fractured and located in densely populated mountainous terrains, leading to higher costs and complications in drilling.
However, state firms have managed to reduce well costs significantly—by 40% for exploration wells versus 2010 and 25% for commercial wells versus 2014—by deploying local service companies, home-manufactured equipment and improving drilling technologies, said Yang.
Shell, which pledged billions of dollars of investment in China’s shale sector, pulled out of shale operations in Sichuan several years ago.
As operators seek to optimize their existing investments, advances in artificial lift technologies are becoming increasingly important. Today’s wells are deeper and longer than they’ve ever been—and in more extreme environments—pushing the limits of conventional artificial lift technologies.
