State oil majors expand domestic exploration to boost national energy security

China's state energy giants are set to raise spending on domestic drilling this year to the highest levels since 2016, focusing on adding natural gas reserves in a concerted drive to boost local supplies.

Responding to central government's call last August to boost domestic energy security, China's trio of oil majors - PetroChina, Sinopec Corp and CNOOC Ltd - are adding thousands of wells at oil basins in the remote deserts of Northwest China's Xinjiang Uyghur Autonomous Region, shale rocks in Southwest China's Sichuan Province and deepwater fields of the South China Sea.

The firms are showing greater risk appetite, expanding investments faster in exploration than production, emboldened by central government's political push and oil prices nearing $60 a barrel, said state oil executives and analysts at consultancy Wood Mackenzie.

"We shall carry through resolutely the State Council's call on stepping up domestic exploration and development and launch an offensive war," PetroChina Chairman Wang Yilin was cited as saying in an in-house newspaper in December.

Offshore specialist CNOOC Ltd said recently that it was confident of achieving its spending target this year, the highest since 2014. 

It pledged to spend twice as much this year in domestic exploratory drilling as in 2016.

"With oil prices at $50, $60 and $70...we're making decent profits," Yuan Guangyu, CNOOC's Chief Executive Officer, said.

CNPC, Asia's largest oil and gas producer and parent of PetroChina, is boosting risk exploration investment five-fold to 5 billion yuan ($741 million) this year from 1 billion yuan last year.

But with oil reservoirs maturing and new discoveries tending to be smaller and more costly to develop, even more drilling is unlikely to reverse China's declining oil outlook, analysts say.

China, set to remain the world's top oil buyer for years to come, is forecast to slip to the 10th largest global oil producer in 2020, down from No.5 for most of last decade, said Wood Mackenzie.

"China will likely continue on the same path as it has in recent years - an overwhelming focus on new gas production, leading to a continued decline in its oil output," said Angus Rodger, research director of Asia-Pacific upstream at Wood Mackenzie.

With central government pushing to reduce energy import dependence and hit environmental targets, gas output is forecast by analysts to rise at 6-8 percent per year through 2020.

China, the world's No.3 gas consumer, overtook Japan as the world's top gas importer in October.

PetroChina, which produces some 70 percent of the country's gas output, will lead the drive, adding thousands of wells in southwestern Sichuan, northern Ordos and northwest Tarim basin, CNPC says on its website.

The major is also ramping up shale development in Sichuan, seeking to catch up with Sinopec Corp which has pioneered China's nascent shale push. 

Despite almost a decade of drilling, shale makes up just 6 percent of China's total gas output because of complex geology and high costs of development.

PetroChina raised its shale gas output by 40 percent last year to 4.3 billion cubic meters (bcm), while Sinopec's production was largely flat at 6 bcm.

"Controlling the largest and best acreage, CNPC has been ramping up aggressively capital and human resource deployment over the past 3-4 months in Sichuan shale," said Woodmac analyst Max Petrov who tracks Chinese majors' investment.

Sinopec declined to comment. CNPC did not respond to Reuters' request for comment.

Deepwater

Beyond 2020, deepwater discoveries in the South China Sea, such as Lingshui 17-2, some 150 kilometers (90 miles) off South China's Hainan Province, will lend growth to China's gas portfolio.

With estimated proven recoverable reserves of 2.5 trillion cubic feet, Lingshui is CNOOC's single-largest fully owned deepwater gas discovery. BG Group walked away with little success after exploratory drilling at the nearby Lingshui 22-1-1 well in 2010.

Aiming to add 50 percent to gas reserves by 2025, CNOOC is expected to step up drilling in the deepwater acreage of the Pearl River Mouth basin and expand earlier major discoveries including Yacheng and Dongfang, both near Hainan Province.

"Natural gas is becoming increasingly popular under the government's green push. And its relatively less risky than oil under long-term off-take deals," said a state oil executive.

Companies, however, will hold off drilling in disputed territorial waters of the South China Sea due to the technological challenges and the lack of experienced global partners who are willing to risk exploring those areas, analysts said.

Short reserve life

Sinopec, traditionally a refiner rather than a driller, has the smallest resource base and may lag its peers, analysts say.

Sinopec's proven oil reserves by the end of 2017 could last less than six years of production at current production levels, versus CNOOC's 10 years, while Sinopec's gas reserve life of eight years is dwarfed by PetroChina's 24 years, according to calculations based on company filings.

Sinopec is expected to boost spending this year, including developing its second shale gas target, Weirong block, in Sichuan. But the momentum of making new finds is waning, said company officials.

"Sinopec is well aware of its problems, but the will to change that seems to have a bottleneck at the top as the company sees itself more of a downstream, petrochemical player," said Woodmac's Petrov.
