One letter from Chinese diplomats to Indonesia"s foreign ministry clearly told Indonesia to halt drilling at a temporary offshore rig because it was taking place in Chinese territory, according to Muhammad Farhan, an Indonesian lawmaker on parliament"s national security committee, which was briefed on the letter.

"It (the letter) was a bit threatening because it was the first effort of China"s diplomats to push their nine-dash line agenda against our rights under the Law of the Sea," Farhan told Reuters.

Within days of the Noble Clyde Boudreaux semi-submersible rig arriving at the Tuna Block in the Natuna Sea to drill two appraisal wells on June 30, a Chinese Coast Guard vessel was at the scene, according to ship movement data. It was soon joined by an Indonesian Coast Guard vessel.

On Sept. 25, the American aircraft carrier USS Ronald Reagan came within 7 nautical miles of the Tuna Block drilling rig. "This is the first observed instance of a U.S. aircraft carrier operating in such proximity to an ongoing standoff" in the South China Sea, AMTI said in a report published in November.

The temporary rig operated until Nov. 19, after which it went to Malaysian waters. Indonesian security minister Mahfud M.D. went to the Natuna Sea last week. He said his visit had nothing to do with China, but said in a public statement that Indonesia would "never surrender an inch" of territory.

This latest saga over oil and gas activity in the South China Sea began on June 30 when a semi-submersible rig, the Noble Clyde Boudreaux, arrived to drill two appraisal wells in Indonesia’s Tuna block located approximately 140 nautical miles north of Natuna Besar. China responded almost immediately, with the CCG 5202 arriving on July 3 to patrol near the rig. Indonesia promptly sent out the KN Pulau Dana, a patrol ship of the Indonesian Maritime Security Agency or Bakamla, which was spotted there on AIS on July 3-4. The Pulau Dana was the first in a long series of patrol vessels from both Bakamla and the Indonesian Navy that visited the rig and pursued Chinese vessels over the past four months, including the KN Tanjung Datu, the KN Pulau Marore, the KN Pulau Nippah, the KRI John Lie, and the KRI Bung Tomo.

By late September, news of China’s activity near the Noble Clyde Boudreaux, first publicized in detail on September 18 by Vietnamese defense blogger Duan Dang, appeared to have reached the ears of the U.S. Navy. A Planet Labs image from September 25 caught the USS Ronald Reagan, en route from Singapore to the Philippines with the guided-missile cruiser USS Shiloh, passing just 7 nautical miles from the rig. The passthrough recalls U.S. presence operations by the amphibious assault ship USS Americaand littoral combat ship USS Gabrielle Giffords near another standoff between China and Malaysia in 2020, but this is the first observed instance of a U.S. aircraft carrier operating in such proximity to an ongoing standoff.

Meanwhile, another survey ship, the Da Yang Hao, was sent to waters within Malaysia’s continental shelf to conduct its own survey. The apparent trigger for its deployment were the activities of the West Capella, a drillship no stranger to oil and gas standoffs, contracted since July by Thailand’s PTTEP for drilling in the Siakap North Petai oil field in Malaysia’s Block K.

China’s persistent efforts to harass oil and gas activity within the nine-dash line have seemingly complicated the investment picture for oil and gas operators in Southeast Asia. The Noble Clyde Boudreauxwas originally contracted by Premier Oil in March 2021, but after a merger deal by which it became Harbour Energy in April, the company “farmed out” its stake in the Tuna block to Russian state-owned operator Zarubezhneft. One of the few foreign oil and gas operators continuing to invest in the South China Sea, Zarubezhneft also made an agreement in May to buy out Rosneft’s stake in several Vietnamese oil and gas blocks. This includes an operating stake in Block 06-01, the site of a standoff between Hanoi and Beijing in 2019, and where the Noble Clyde Boudreaux itself had a contract for new drilling abruptly canceled in 2020, possibly due to concerns over increased CCG activity at nearby Vanguard Bank.

Internal reorganization in 2007 means there is no steady number of drilling companies at CNPC at this time, Mr Zheng said. But the number of its rig fleet provides a taste for the company’s size: As of September 2007, it owned 1,035 drilling rigs, mostly land rigs with a few shallow offshore units, plus 2,000 workover rigs. Mr Zheng said 22 million meters (72.18 million ft) were drilled in 2006. Although he expects that number to stay about even for 2007, he noted that 22 million meters “is double what we drilled just five years ago, only about 11 million meters (36.1 million ft).”

The most active fields nowadays, in terms of rig numbers, are the Sichuan and Changqing fields in the Southwest and the Xinjiang field in the Northwest, Mr Zheng said. But the king of CNPC fields and the biggest-producing field in China is still Daqing, home to the “iron man” spirit.

The Daqing Drilling & Exploration Group (DDEG), a massive entity within itself, owns four drilling companies and 121 drilling rigs, plus additional workover rigs, said Liu Fu, DDEG assistant president and general manager.

Case in point: In September, Drilling Contractor toured No. 1 Drilling Company’s Rig 70163 on the Daqing Oilfield. The drilling team, which had drilled three other deep wells since 2005, was three months and 3,600 m into a 4,400-m MD/3,800-m TVD gas exploration well using downhole motors and MWD. With no top drive or rotary steerable equipment, drilling through the volcanic rock has been tough going. Average penetration stood at about 1 m (3.28 ft) per hour in September.

Although many of CNPC’s subsidiaries, such as DDEG, work extensively around the world, the bulk of its international work is still carried out by subsidiary Great Wall Drilling Company (GWDC). Founded in 1993, the company specializes in onshore drilling and operates more than 180 rigs in 26 countries (including four joint ventures), ranking it among the biggest land drilling contractors in the world.

Most of GWDC’s fleet were manufactured by CNPC’s own factories, said Great Wall vice president Du Jun. A big portion of them are 1,500-hp to 2,000-hp rigs with depth capabilities ranging from 2,000 m to 9,000 m (about 6,600 ft to 29,000 ft). Mr Du noted that some clients have requested 3,000-hp rigs, but GWDC determined there was not sufficient work to justify the cost of acquiring such a rig at this time.

Still, GWDC has kept busy. Since a major reorganization in 2001, the company’s total footage drilled outside of China has increased by an average of 37% every year, from 355,000 m (1.16 million ft) in 2001 to 1.7 million m (5.58 million ft) in 2006. A total of 35 Great Wall rigs are working in Kazakhstan, its biggest market. Other major operating areas include Sudan and Venezuela.

Additionally, GWDC has access to the more than 1,000 rigs owned by CNPC. However, Mr Du acknowledged that, at this point, no additional CNPC rigs are available for the international market. “Just 2-3 years ago, we were actively trying to send more rigs outside of China, but it’s a very different story now.”

Now, CNPC does not have enough rigs to meet its own drilling needs in China, both Mr Zheng and Mr Du said. So unless it’s for CNPC’s own overseas development, no more rigs will be sent outside of China.

CNPC is working to amend that lack of rigs though. The company owns several drilling rig manufacturing companies, the biggest of which is Baoji Oilfield Machinery (BOMCO). The company is capable of building 9,000-m (29,500-ft) depth rigs and is targeting the building of 12,000-m (39,400-ft) rigs. Overall, CNPC is building and/or refurbishing 40-50 rigs a year on average, Mr Zheng said. “We don’t have enough rigs to meet our needs. Rig and parts manufacturers in China are very, very busy.”

An integrated drilling project in Iran in 2000 changed that. GWDC signed a contract with National Iranian Oil Company to drill 19 wells using three rigs in Tabnak, Iran’s largest onshore, sweet gas field. From the start, drilling progressed extremely slowly. The formation’s low downhole pressure made it difficult to drill with a mud system. Lost circulation, cave-ins and sloughing were encountered.

Other than technological challenges, Mr Zheng Yi in Beijing noted that cost increases — on everything from casing/drill pipe to rigs and personnel — have impacted some projects.
