The automatic operation equipment for minor workover is mainly composed of a wellhead operation device, hydraulic elevator, pipe and rod transmission and arrangement device and electro-hydraulic control system.

The device adopts the structural form of dispersing the functional modules and integrated installation on the workover rig: with the hydraulic tong, manipulator and anti splash snap device set on the derrick of the workover rig, which can expand and rotate, and the safety slip is installed above the BOP.

The device only needs to install safety slips, which realizes rapid installation and migration and shortens the auxiliary working time. The device has the function of moving back and forth, left and right, which is convenient to align the wellhead. The height of the hydraulic tong is adjustable and can adapt to the wellhead with different heights. Hoisting equipment and special transport vehicles are not required for the installation and removal of the device.

The main electric control box can be installed on the operation vehicle or integrated into the modular wellhead operation device. The make-up torque of various oil pipes is set on the touch screen to realize automatic make-up and break-down. Equipped with video monitoring, process prompt, safety alarm, etc. The control system has a perfect action interlocking function to ensure the safety and reliability of the workover operation process. All of the electric cabinets, sensors, connectors meet the requirement of Explosion-proof on field.

The land drilling market worldwide is structured primarily as a rental market, not a sales market, where land drilling companies lease their rigs to E&P companies for an agreed period of time – weeks, months, or years – at a day-rate. The rigs are then used to drill wells and execute the E&P’s drilling programs.

Drilling opportunities are analysed and explored in order, leaving a series of dry holes, until a discovery is made. It is rare for an E&P company to actually own the rigs which they operate, but there are some exceptions such as Chesapeake, who will purchase their own fleet of rigs.

Investors require a minimum level of return for their investment dollars in drilling operations, and typically equate cost with risk. These turnkey drilling contracts may limit risk by guaranteeing a minimum number of wells that can be drilled with the rig. The contract will also outline how the rig can be used – including the pieces of equipment, when to change pieces, temperature and pressure tolerances and the weight of mud.

Nabors operates the world’s largest land drilling rig fleet, with around 500 rigs operating in over 25 countries – in almost every significant O&G basin on the planet. It also has the largest number of high-specification rigs (including new AC rigs and refurbished SCR rigs) and custom rigs, built to withstand challenging conditions such as extreme cold, desert and many complex shale plays.

Headquartered in Tulsa, Oklahoma, H&P is a global business with land operations across the US, as well as offshore operations in the Gulf of Mexico. It is engaged primarily in the drilling of O&G wells for E&P companies, and recognised for its innovative FlexRig technology.

Patterson-UTI operates land based drilling rigs, primarily in O&G producing regions of the continental US, and western Canada. The company also provides pressure pumping services to US E&P companies and specialist technology, notably pipe handling components, to drilling contractors globally.

Precision is an oilfield services company and Canada’s largest drilling rig contractor, with over 240 rigs in operation worldwide. The Company has two segments. The Contract Drilling Services segment operates its rigs in Canada, the United States and internationally. The Completion and Production Services segment provides completion and workover services and ancillary services to O&G E&P companies in Canada and the US.

Pioneer operates a modern fleet of more than 24 top performing drilling rigs throughout onshore O&G producing regions of the US and Colombia. The company also offers production services include well servicing, wireline, and coiled tubing services – supported by 100 well-servicing rigs, and more than 100 cased-hole, open-hole and offshore wireline units.

In Texas, generally considered to be the centre of US land drilling, RigData reports that there are currently 678 active rigs – split between Helmerich & Payne (160), Patterson-UTI (85), Nabors (64), Precision Drilling (39) and 77 other drillers (330).

Most new onshore rigs, both drilling and work over rigs, are built by OEMs in China. In the US, the larger vertically integrated land drillers have in-house manufacturing operations, so they will outsource some equipment construction, but assemble the new rigs at their own facilities. The leading provider of US newbuild rigs is National Oilwell Varco.

The secondary market, where existing rigs are sold, is largely auction dominated with mostly older rigs changing hands. As a rule, the big land drillers do not sell their newbuild rigs, as each has their own flagship designs.

First oil from Phase 2 was produced at WHP-C and delivered to Ming Zhu FPSO in July 2007. Six additional platforms and one of the world’s largest floating production vessels Peng Bo were constructed in Phase 2. At peak, the construction of the Phase 2 project involved over 8,000 workers in 12 locations in 5 countries, making it a world-class operation in China, both in terms of technological complexity and productivity.

In 2014 ConocoPhillips entered a new era of collaboration, as operational control of the Bohai Penglai Field was transferred to CNOOC Limited per the terms of Production Sharing Contract (PSC) 20 years after the original Bohai PSC was signed. Later that month, the newest phase of field development began when Chairman and CEO Ryan Lance approved the first new platform to be installed since the Bohai Phase 2 project was completed in 2010.

The Bohai Penglai asset is managed by CNOOC China Limited and ConocoPhillips China through a joint management committee (JMC). CNOOC China Limited holds 51 percent working interest, and ConocoPhillips holds the remaining 49 percent. The Peng Bo Operating Company was established within CNOOC’s Tianjin branch office to operate the Penglai Field, the largest within CNOOC ’s Bohai Sea portfolio. Twenty-two ConocoPhillips China personnel are directly involved with CNOOC in Tianjin, in the JMC fabrication yards, professional representative positions, and project management team and technical secondee roles. ConocoPhillips China’s Beijing office provides management oversight, multidisciplinary technical support and administrative capabilities.

Bohai Phase 3, which began operations in third quarter 2018 is the largest new project initiated since the ConocoPhillips upstream-downstream split. The project includes three wellhead platforms, three drilling-completion-workover rigs, a central process platform, 186 new wells, 49 sidetracks and brownfield modifications.

SHANGHAI/HANOI (Reuters) - A Chinese oil rig has finished drilling near the disputed Paracel islands in the South China Sea after finding signs of oil and gas and is being moved away from the area, more than two months after its deployment damaged relations with Hanoi.Chinese ships are seen on the horizon guarding the Haiyang Shiyou 981, known in Vietnam as HD-981, oil rig (2nd R) in the South China Sea, July 15, 2014.

The Vietnamese coastguard said the $1-billion rig had been towed from contested waters. China’s official Xinhua news agency said the rig would be relocated off the southernmost island province of Hainan. It gave no timeframe.

The rig’s relocation could reduce tensions between the two neighbours after one of the worst breakdowns in ties since they fought a brief war in 1979.

Its movement toward Hainan is also likely to be welcomed by Washington, which had criticised China’s decision to put the rig in waters disputed with Vietnam, calling it a “provocative” act.

Hanoi had said the rig was in its 200-nautical-mile exclusive economic zone and on its continental shelf. Beijing had said it was operating completely within its waters around the Paracel islands, which China occupies.

China National Petroleum Corporation (CNPC), the country’s dominant oil and gas producer, said in a statement the rig “smoothly completed” its drilling on Tuesday and found signs of oil and gas. The next step would be to analyse the geological data and evaluate the layers of oil and gas, it said.

China had previously said the rig was scheduled to explore the waters around the Paracels until mid-August. It was not clear why it had finished one month ahead of schedule, although Xinhua said July was the beginning of the typhoon season.

Wu Shicun, president of the National Institute for South China Sea Studies, a Chinese government think tank on Hainan, said he believed the rig completed its work ahead of schedule because of good weather before the typhoon season began. “The place has fairly good oil and gas potential. It looks promising,” said Wu, an expert on China’s energy ambitions in the South China Sea.

The rig was towed from its original position overnight to beyond what Hanoi considers its exclusive economic zone, Lieutenant-Colonel Ngo Minh Tung of the Vietnamese coastguard told a small group of reporters on one of the maritime agency’s ships in the area.

On Tuesday, the same coastguard vessel was chased off by a group of Chinese ships in what had been a near daily cat-and-mouse routine between boats from both sides since the rig was deployed on May 2. Vietnamese Prime Minister Nguyen Tan Dung demanded that China not send any more rigs into Vietnamese waters.

The deployment was a major test for Dung, especially when deadly anti-Chinese riots broke out in Vietnam in May, triggering protests from China. Several people were killed.

It is China’s newest and most advanced rig, and can drill in waters up to 3,000 m (9,840 ft) deep, about double that of the other two rigs China uses for deep sea work, industry sources say.

Chinese industry experts have said the rig had a good chance of finding enough gas to put the area into production. That would give China its first viable energy field in the disputed South China Sea, but make it a source of friction with Hanoi for years to come.

Vietnam has two fields to the left of where the rig had been stationed, much closer to its coast, where U.S. giant Exxon Mobil Corp discovered oil and gas in 2011 and 2012.

Through a little research I discovered the existence of a museum dedicated to Sichuan’s ancient brine / salt / gas industry. Called The Salt Museum, it is located in Zigong City, named after two of its famous salt wells, about three hours’ drive south of the provincial capital Chengdu (figure 1). I resigned myself to the fact that it was highly unlikely I’d be close to China in the near future, let alone Zigong. Then earlier this year, out of the blue, a business-related trip to Chengdu materialized, and I was determined to visit The Salt Museum while over there. It all worked out, and this article is the result. My aim is to provide interested readers with an understanding of the fascinating achievements of these people hundreds of years ago. As with my previous article this is not a scholarly analysis, but rather an amateur’s efforts to share his enthusiasm, and provide entertaining and stimulating reading.

When a break in our work responsibilities allowed it, I and my Geo-X colleagues, Bo Li and Andrew Royle, set off to Zigong, with our generous and gracious hosts from the Sichuan Geophysical Company (S.G.C.), Gang Lin and Zhirong Li. To drive through rural Sichuan is interesting, as one gets a sense of the intensity of human development in one of China’s richest regions. The heavily populated portion of Sichuan is a large basin, flanked by the Himalayan Plateau to the west, the Long Men Mountains to the north, and the Hua Ying Mountains to the south. The Yangtze River flows along the southern edge of the basin, and numerous tributaries drain south through the rich agricultural lands and into the Yangtze . With its fertile, well watered soil, and mild climate, Sichuan is one of China’s most productive farming regions. Since ancient times, Sichuan has been called “heaven country” within China. The most common crops include wheat, canola, rice, cotton, barley, corn, yams, tobacco, fruits and vegetables. On higher, less fertile ground, huge areas are devoted to the cultivation of mulberry bushes (figure 2), which feed one of the world’s oldest and biggest silk producing industries.

Naturally, with such attractive conditions for human habitation, Sichuan has been occupied by humans since the early dawn of our existence. The countryside has been worked by the human hand for so long, that it is hard to spot a single wild area in the basin proper. Even steep hillsides are terraced for farming, and ancient family crypts hewn into rock cliff outcrops can be spotted frequently from the highway. The contrast between the luxury cars speeding along the modern 6-lane highways, and the ancient terraces, tombs and irrigation systems is startling, but one can easily imagine one long continuous evolution of human technology here, from thousands and thousands of years ago, to the present. Many of China’s ancient technical accomplishments came from this region, including sophisticated irrigation techniques, and what I am particularly interested in, their drilling technology.

At some point around 2,000 years ago the leap from hand and shovel dug wells to percussively drilled ones was made (figure 4). By the beginning of the 3rd century AD, wells were being drilled up to 140m deep. The drilling technique used can still be seen in China today, when rural farmers drill water wells. The drill bit is made of iron, the pipe bamboo. The rig is constructed from bamboo; one or more men stands on a wooden plank lever, much like a seesaw, and this lifts up the drill stem a metre or so. The pipe is allowed to drop, and the drill bit crashes down into the rock, pulverizing it. Inch by inch, month by month, the drilling slowly progresses. It has been speculated that percussive drilling was derived from the pounding of rice into rice flour. When I read of this technique in Salt, I imagined a fairly crude technology. I had no idea how sophisticated these drilling methods became, to the point where these people really had developed most of the tools and techniques one might see on a modern drilling rig, albeit on a smaller scale and without the benefits of modern machining methods.

Figure 13. An ancient sketch originally fro m "The Annals of Salt Law of Sichuan Province". A "Kang Pen" drum is seen in the centre foreground, with gas pipes directly feeding the salt stoves on the right. At the top, brine from a remote well is being carried in buckets by men, who feed it into a bamboo pipeline that runs down to the stoves. One of the carriers is being paid at top left, and it appears that a blow out is depicted on a new well being drilled in the left foreground; maybe the men operating the drill rig have run away, as tragically happened at a Chongqing, Sichuan sour gas well, late 2003.

My brief visit to Sichuan left me intrigued, fascinated, and eager to learn more about China’s ancient technical accomplishments. I can highly recommend the region as a place to visit, not only for its interesting historical sites, but also for its natural beauty (most of Sichuan is mountainous and unpopulated, especially the west, with bamboo forests, and panda bears), its rich culture with many interesting ethnic minorities, its delicious food, great shopping, and its wonderful, friendly people. However, the highlight of my trip was the visit to the Salt Museum, and I hope I have passed on my enthusiasm for this topic to readers.

Tensions between China and Vietnam over the disputed South China Sea are at their highest levels in years. On May 2, the state-owned China National Offshore Oil Corporation (CNOOC) placed its deep sea drilling rig HD-981 in disputed waters south of the Paracel Islands. Vietnam objected to the placement, declaring that the rig is located on its continental shelf. China has since sent approximately 80 ships, including seven military vessels, along with aircraft to support the rig. In response, Hanoi dispatched 29 ships to attempt to disrupt the rig’s placement and operations.

The implications of these developments are significant. The fact that the Chinese moved ahead in placing their rig immediately after President Obama’s visit to four Asian countries in late April underlines Beijing’s commitment to test the resolve of Vietnam, its ASEAN neighbors and Washington. Beijing may also be attempting to substantially change the facts on the seas by moving while it perceives Washington to be distracted by Russian aggression inUkraine, developments in Nigeria, and Syria. If China believes Washington is distracted, in an increasingly insular and isolationist mood and unwilling to back up relatively strong security assertions made to Japan and the Philippines and repeated during President Obama’s trip, these developments south of the Paracel Islands could have long term regional and global consequences.

A1:The war of words between Beijing and Hanoi has largely focused on the status of the area where HD-981 was placed. Vietnamese officials insist that it lies on their continental shelf, where according to the UN Convention on the Law of the Seas (UNCLOS), Vietnam has exclusive rights to all mineral and hydrocarbon resources.

The rig was placed near the edge of two hydrocarbon blocks already created by Hanoi, though not yet offered for exploitation to foreign oil and gas companies. It also sits near blocks 118 and 119, where U.S.-based ExxonMobil discovered substantial oil and gas reserves in 2011 and 2012. In 2013, Exxon and Vietnam’s state-owned PetroVietnam announced plans to build a $20 billion power plant to be fueled by the oil and gas from those blocks. Those discoveries help explain why CNOOC chose to place HD-981 nearby.

China’s Ministry of Foreign Affairs has responded to Vietnam’s complaints by insisting that the rig was placed “completely within the waters of China"s Paracel Islands.” This presumably refers to the 200 nautical mile exclusive economic zone and continental shelf that those islands—which are occupied by China but claimed by Vietnam—would generate under UNCLOS if they met certain requirements.

A3:The deployment of HD-981, which Beijing insists will remain in place until August 15, has clearly ratcheted China-Vietnam tensions to a new level. Hanoi seems determined to disrupt the rig’s operations. And, in contrast to the Philippines, it has the capabilities—Russian-built Kilo-class submarines and an outdated but sizeable surface and air fleet—to do so. This means there is a real threat that acts of brinksmanship, like the recent ramming of Vietnamese vessels, could escalate quickly. Vietnam’s neighbors and outside partners like the United States must use every available channel to urge caution on both sides.

On the other hand, Vietnam’s relative naval capabilities will likely help temper Chinese assertiveness. After all, despite the presence of Chinese naval vessels around HD-981, it appeared that only Chinese Coast Guard vessels were involved in harassing and deterring Vietnamese ships attempting to enter the waters around the rig. The two nations’ and their leaders are as familiar with each other as anyone in the Asia Pacific, and they have substantial channels for communications, including top-level naval hotlines. This could also help avoid a larger crisis.

Vietnam has already launched a diplomatic campaign to build support abroad and paint China as the aggressor. Given other recent provocations by China against its neighbors, this will prove easy. This weekend, Vietnamese prime minister Nguyen Tan Dung will join his fellow leaders from across Southeast Asia at the ASEAN Summit. The placement of the drilling rig, along with China’s patrols at Malaysia’s James Shoal earlier this year and attempts to block resupply of Philippine troops at Second Thomas Shoal in March, will ensure that the South China Sea disputes take center stage. There is no telling who will blink first in the stand-off over HD-981, but the one thing that is certain is that China’s newest provocation will further heighten the threat perception among ASEAN states and drive them closer to each other and interested outside parties, especially Japan and the United States.
