An oil well is a boring in the Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well. Wells are created by drilling down into an oil or gas reserve that is then mounted with an extraction device such as a pumpjack which allows extraction from the reserve. Creating the wells can be an expensive process, costing at least hundreds of thousands of dollars, and costing much more when in hard to reach areas, e.g., when creating offshore oil platforms. The process of modern drilling for wells first started in the 19th century, but was made more efficient with advances to oil drilling rigs during the 20th century.

Until the 1970s, most oil wells were vertical, although lithological and mechanical imperfections cause most wells to deviate at least slightly from true vertical (see deviation survey). However, modern directional drilling technologies allow for strongly deviated wells which can, given sufficient depth and with the proper tools, actually become horizontal. This is of great value as the reservoir rocks which contain hydrocarbons are usually horizontal or nearly horizontal; a horizontal wellbore placed in a production zone has more surface area in the production zone than a vertical well, resulting in a higher production rate. The use of deviated and horizontal drilling has also made it possible to reach reservoirs several kilometers or miles away from the drilling location (extended reach drilling), allowing for the production of hydrocarbons located below locations that are either difficult to place a drilling rig on, environmentally sensitive, or populated.

The well is created by drilling a hole 12 cm to 1 meter (5 in to 40 in) in diameter into the earth with a drilling rig that rotates a drill string with a bit attached. After the hole is drilled, sections of steel pipe (casing), slightly smaller in diameter than the borehole, are placed in the hole. Cement may be placed between the outside of the casing and the borehole known as the annulus. The casing provides structural integrity to the newly drilled wellbore, in addition to isolating potentially dangerous high pressure zones from each other and from the surface.

The pipe or drill string to which the bit is attached is gradually lengthened as the well gets deeper by screwing in additional 9 m (30 ft) sections or "joints" of pipe under the kelly or topdrive at the surface. This process is called making a connection. The process called "tripping" is when pulling the bit out of hole to replace the bit (tripping out), and running back in with a new bit (tripping in). Joints can be combined for more efficient tripping when pulling out of the hole by creating stands of multiple joints. A conventional triple, for example, would pull pipe out of the hole three joints at a time and stack them in the derrick. Many modern rigs, called "super singles", trip pipe one at a time, laying it out on racks as they go.

This process is all facilitated by a drilling rig which contains all necessary equipment to circulate the drilling fluid, hoist and turn the pipe, control downhole, remove cuttings from the drilling fluid, and generate on-site power for these operations.

The production stage is the most important stage of a well"s life; when the oil and gas are produced. By this time, the oil rigs and workover rigs used to drill and complete the well have moved off the wellbore, and the top is usually outfitted with a collection of valves called a Christmas tree or production tree. These valves regulate pressures, control flows, and allow access to the wellbore in case further completion work is needed. From the outlet valve of the production tree, the flow can be connected to a distribution network of pipelines and tanks to supply the product to refineries, natural gas compressor stations, or oil export terminals.

Workovers are often necessary in older wells, which may need smaller diameter tubing, scale or paraffin removal, acid matrix jobs, or completing new zones of interest in a shallower reservoir. Such remedial work can be performed using workover rigs – also known as pulling units, completion rigs or "service rigs" – to pull and replace tubing, or by the use of well intervention techniques utilizing coiled tubing. Depending on the type of lift system and wellhead a rod rig or flushby can be used to change a pump without pulling the tubing.

The cost of a well depends mainly on the daily rate of the drilling rig, the extra services required to drill the well, the duration of the well program (including downtime and weather time), and the remoteness of the location (logistic supply costs).

HONG KONG, May 29 (Reuters) - A Chinese oil rig whose deployment to waters claimed by Vietnam early this month triggered a rupture in ties has a good chance of finding enough gas to put the area into production, Chinese industry experts said.

For now, China has said nothing about the potential of the area. The first round of drilling had been completed, the rig operator said on Tuesday, without giving any results from the tapped wells.

The $1 billion deepwater rig owned by state-run China National Offshore Oil Company Group (CNOOC Group), parent of flagship unit CNOOC Ltd, is scheduled to explore until mid-August.

“The place where the rig is drilling at the moment is likely to be a gas field. China conducted three-dimensional geological surveys before moving the rig there,” said Wu Shicun, president of the National Institute for South China Sea Studies, a Chinese government think-tank on the southern island of Hainan.

Deployment of the rig on May 2 set off deadly anti-Chinese riots in Vietnam while scores of Vietnamese and Chinese ships remain squared off around the platform. There have been several collisions.

The rig lies approximately 330 km (205 miles) east of Vietnam and 370 km from the southern coast of Hainan. It is just below the Paracel island chain occupied by China and claimed by Hanoi. Earlier this week the rig was moved after having been some 20 nautical miles closer to central Vietnam’s coast.

Hanoi has said the Haiyang Shiyou 981 rig is in its exclusive economic zone. China says its biggest and most advanced mobile energy platform was operating within its waters.

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

No production had taken place in Blocks 118 and 119, Do Van Khanh, head of state-run PetroVietnam Exploration Production Corporation, told Reuters. He declined to discuss the rig.

Neither CNOOC Group nor CNPC could be reached for comment on the rig or the field despite repeated attempts. An executive at China Oilfield Services Ltd , the service arm of CNOOC Group and the rig’s operator, declined to give details on drilling results so far.

Experts said if the rig found commercial reserves, China would bring in platforms for production and pipe-laying ships to build the infrastructure to transfer gas to vessels. That process could take several years while production could last decades.

Hanoi, for example, said last week it was considering taking legal action against China following the rig’s deployment. The Philippines, another claimant in the South China Sea, challenged China by filing a case with an international arbitration tribunal in late March.

Some Chinese industry experts said they believed the 981 rig - once called “mobile national territory” by CNOOC - would be moved elsewhere in the South China Sea once exploration was completed near the Paracel islands.

“The rig was designed, meant for oil exploration in the South China Sea,” said Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University and an adviser to China’s National Energy Administration, the top regulator of China’s energy industry.

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.

Once the substructure is set in place, the process of setting up the rig floor begins. Begin by installing stairways and guardrails to allow access to the rig floor. Then, the drawworks is set in place and secured to the substructure. On mechanical rigs, the engines are set in place and the compound and associated equipment connected to the drawworks. On electric rigs, the electric cables (lines) are strung to the drawworks.

The bottom of the mast is raised to the rig floor and pinned in place. The crown section is then raised into place on the derrick stand. The "A-legs" are raised and pinned into place. The monkeyboard is pinned in place on the mast and all lines and cables are laid out to prevent tangling when the mast is raised. A thorough inspection of the mast should be made before raising the mast/derrick. The mast is now ready to be raised. The engines are started (see Installing the Power System), and the drilling line is spooled onto the drawworks drum. Once the mast has been raised and pinned, the remaining floor equipment can be set into place. If the rig has safety guylines, they must be attached to the anchors and properly tensioned prior to continuing the rigging up process. A derrick emergency escape device is installed on the mast.

The hoisting mechanism on a drilling rig. It is essentially a large winch that spools off or takes in the drilling line and thus raises or lowers the drill stem and bit.†

A diesel, Liquefied Petroleum Gas (LPG), natural gas, or gasoline engine, along with a mechanical transmission and generator for producing power for the drilling rig. Newer rigs use electric generators to power electric motors on the other parts of the rig.†

Chinese authorities plan to position their first homegrown semi-submersible oil rig in a deep-water field in the disputed South China Sea to show rivals how far it’s willing to go for energy security and possibly to expand its political clout, observers believe.

Vietnam’s claims come closest to the Chinese gas field and Hanoi is unlikely to protest if the rig stays on site without expanding, said Alexander Vuving, professor at the Daniel K. Inouye Asia-Pacific Center for Security Studies in Hawaii. But in 2014 a Chinese rig positioned in disputed waters touched off boat ramming and deadly anti-China riots in Vietnam. That sort of flap could pop up again, Vuving said.

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.

Are you trying to land a job on a drilling rig and start a career in the oil and gas industry? Like you - I started at the bottom and over a 15-year career progressed from an entry-level position to a project manager earning a six-figure income $$$,$$$. After this, I worked as a Recruiter and I am now an Executive CV / Resume Writer so have a very good understanding of the environment and what it takes to progress a career in the international oil and gas industry. This article will help you land an entry-level position like roustabout, operator, rigger or trainee graduate. It also contains a comprehensive guide of all the positions on a rig and descriptions of various types of rigs so that you can choose a career direction.

It is a realistic option for you to break into the industry, it just requires patience and for you to apply everywhere necessary but make sure your CV is looking its absolute best before you apply, if not, it’s a wasted exercise... You only have one chance at making the right first impression!

Jobs on the rigs will include cleaners, painters and roustabouts (both entry-level), riggers (slingers), floor hands, catering staff, crane operators, welders, electricians, mechanics, motormen, engineers, chief engineers, derrickman, assistant drillers, drillers, tool pushers, warehousemen, medics, (HSE) safety supervisors, ballast control men, dynamic position (DP) operators, barge operators, barge engineers, offshore installation managers (OIMs), rig managers and rig superintendents.

All these positions except entry-level will require some type of prior experience and specialist training unless you just get very, very lucky. Below is a guide for a more in-depth look at the permanent positions on a rig.

If you want to work overseas, understand that drilling contractors seldom if ever send lower echelon people overseas. An overseas crew usually have Expatriate Rig Managers, Tool pushers, Drillers, Assistant Drillers, Crane Operator, Barge Engineer, Electrician and Mechanic. Maybe even a few more, maybe a few less, it varies from company to company, rig to rig, job to job. All lower positions will be locally hired!

You are not going to see expatriate roustabouts, cleaners, painters, riggers or floor hands going overseas and working a 28/28 schedule because the country where the rig is working will use (nationals) for those jobs. Often local governments stipulate that a certain percentage of the crew needs to be national so expatriate positions are reduced.

The emergency training that is offered to people who work in an offshore facility or are about to join offshore vessels is known as BOSIET (Basic Offshore Safety Induction and Emergency Training). BOSIET is a very simple training program that covers all major and minor points of safe working in the offshore facility. The course duration is 3 days. The various aspects of the BOSIET training program can be explained below:The first step in the offshore training program is about Safety Inductions. This aspect deals with all the necessary steps that a newly inducted person is required to follow while working on the offshore installation. Points on how to react in case there is an emergency situation like fire, accidents of waste-water disposal systems and drugs and alcohol abuse are covered during this section.

BOSIET is just the first step in terms of offshore survival training courses. After gaining the required safety training through BOSIET, a person can opt for further emergency training courses. The validity of this course is for four years. After the validity period is over, in order to continue with the validation there is a refresher course called FOET (Further Offshore Emergency Training) that is also offered. The duration of the FOET course is only one day. If by any chance, an offshore worker fails to take the refresher course then the person must repeat the entire BOSIET course again to continue working offshore.

BA-EBS:The aims and objectives of the training are to ensure that the delegate gains the required knowledge and understanding of the hazards and properties of a Compressed Air Emergency Breathing System (CA-EBS) and appropriate practical emergency response actions to take should the requirement for emergency deployment arise.

The BOSIET emergency training is offered in all countries. The training that is imparted contains both theory and practical application so that the learner can understand all the aspects easily. The total hours of training comes to around 22.5 hours. In order to certify that a person has successfully completed the training, a certificate is issued to the person. This certificate is to be presented to any new employer if you wish to work offshore and you will need to carry a copy of this with you when checking in at the heliport.

This course aims to ensure every member of the offshore oil and gas industry has a basic level of safety knowledge. A 2-day OPITO Approved training course is available at locations throughout the UK, covering nine basic safety elements including:Introduction to the Hazardous Offshore Environment

Many UK employers require MIST and BOSIET training as well as a medical certificate as a minimum requirement for working offshore. For experienced offshore workers:

There are many other Oil and Gas courses that are job-specific but once you are on board with a new employer they often plan your training and keep you up to date.

Laid out below are the basic jobs on an offshore drilling rig starting with the lowest level of the worker through to the Offshore Installation Manager (OIM) also including the support staff after the OIM.

Roustabout - The job of roustabout is about the easiest entry level job to get. It involves a lot of hard manual labor and long work hours. Roustabouts typically are involved on the main deck with painting and sandblasting, unloading pipe and other kinds of physical work. During breaks they also fill in for the roughnecks on the rig floor.

Roughneck - Higher up are the roughnecks also known as floor hands who do the jobs on the rig floor. The job of the roughnecks is to make connections in the drill pipe using pipe tongs or an automatic device known as an “iron roughneck”. Roughnecks “trip pipe” joints of drill pipe into and out of the hole when drill bits, etc, need to be changed.

Derrickman - Aligns and manipulates the sections of pipe or drill stem from a platform on the rig derrick during the removal and replacement of strings of pipe, or drill stem and drill bit. Assist in setting up, taking down and transporting drilling and service rigs. Supervises the roughnecks. This job entails working at height in the derrick usually at 170ft.

Crane Operators - Responsible for all crane operations on the rig and to and from the supply boats. Cranes are used to load supplies, such as casing, pipes and rig equipment, onto the oil rig. Crane operators also assist in general labour around the rig. Crane operators supervise the roustabouts and the crane operator assistant. This is a senior deck crew position.

Assistant Driller (AD)- Runs the work crew and takes information from the driller and gives it to their crew. While the assistant driller acts in a predominately supervisory role, they may also work alongside the roughnecks to run machinery. ADs train roughnecks to recognize abnormal well conditions in order to prevent leaks and rig blowouts.

Driller - A driller is a person in charge of the rig floor and of overseeing the drilling of an oil well. They directly control the rate of drilling and it is a skilled position that requires extensive knowledge of rock types and drilling procedures. Drillers must be highly knowledgeable and make real-time decisions in a calm and controlled manner.

Tool Pusher - On a land drilling rig the tool pusher may be the rig manager and responsible for all operations, but on drillships and offshore drilling rigs, tool pushers are in charge of the drilling department and report to the Offshore Installation Manager (OIM).

OIM (Offshore Installation Manager) - is the most senior manager of an offshore installation. If an emergency were to arise they control the situation and manage the response. He is responsible for all personnel and operations and reports to the Rig Manager who is onshore.

Rig Electrician - They are responsible for ensuring that all electrical systems on the rig are functioning properly. Duties include repairing, maintaining, installing and operating all electrical equipment on the rig. They need to be competent in the use of electricity in hazardous areas and communicate with the rig crew.

Motorman / Rig Mechanic - The primary job function is oil rig equipment maintenance. The motorman checks the rig motors and other mechanical equipment on the rig for proper functioning and takes all necessary steps including lubrication and regular maintenance to render equipment in a working condition.

Barge Engineer - The Barge engineer is in charge of control room operations, including anchor handling, rig stability and supply vessel operations. A barge engineer should have a good knowledge of Coast Guard operations and water safety. Most barge engineers have experience as master merchant in the Navy.

Radio Operator - Efficiently communicating vital information between land bases, rigs, boats and helicopters. Sets up, operates and maintains sensitive equipment to establish verbal, data and encoded interactions regarding emergency situations, weather conditions and important job directives.

The most commonly used rigs in the industry are Jack-ups, used to drill in shallow water, Semi-submersibles used to drill in deep water and land rigs which are moved on trailers and spotted on concrete bases on land, I will also mention fixed platforms which can have drilling facilities on board. The most expensive to run is the semi followed by the jack-up and finally the land rig. This is all down to the size, equipment differences and also the difficulty with logistics to and from the rig. Each rig will have similar drilling equipment on board but some will vary due to the nature of the rig.

These types of rigs come in a variety of sizes depending on the type of well you will be drilling. The rig breaks down into many parts so that it can be transported with trucks and trailers. First, a concrete base will be laid at the location of the well and a pit will also be dug next to the location for the cuttings from the well to be temporarily dumped into. These rigs can be assembled very quickly usually within 3-7 days and can be transported in as little as 12 truckloads.

These rigs are towed into location and then jack their 3 legs down until the legs reach the sea bed. Some larger rigs can have up to 5 legs. The rig will then raise itself out of the water to the deserved height. Jack-ups are good in water depths of up to 400ft (120m) and can be found most commonly in the North Sea because of the seas shallow nature. Once settled the Jack-up rig has a static base in which to drill from. Occasionally rocks has to be placed around the legs to keep the platform from sinking or tilting into the seabed.

Sit on pontoons and float high above the water. The ballast tanks can be adjusted to raise or lower the rig and they can be moved under their own power or towed into place. Once in place the rig will deploy its six anchors and they will be tensioned accordingly to move the rig over the drilling location. Semi-Submersible rigs can be used in water depths from 200ft – 10,000ft (60m – 3000m). The main difference with drilling from a Semi is that the rig is not static and is constantly moving with the swell, therefore the drill pipe moves up and down with the swell. The rig is fitted with heave compensators which keep the drill pipe firmly at the bottom whilst drilling. When the rig moves upwards the heave compensators push down the drill pipe and vice versa.

A drillship is a mobile offshore drilling rig where a mono-hull ship, catamaran, triple-hull ship, or barge is adapted or built for use as a platform. After reaching the well position, the drillship first gets into position with the mooring system or dynamic positioning (DP) system and then begins to drill a well. From the action of wind and waves, the drillship will encounter a heaving motion and sway on all sides, hence, it needs measures such as a drilling string heave compensation device and swing angle reduction device as well as dynamic positioning (DP) to guarantee displacement of drillship within the allowable limits, so as to properly drill a well.

Fixed drilling platforms offer stability but not mobility. Today they’re usually used to tap shallow, long term oil deposits. These platforms are permanently anchored directly to the seabed with the use of a steel structure known as a “jacket”. This rises from the seabed to support a surface deck that is above the ocean. The jacket provides the rig’s sturdy base and holds everything else out of the water, while the drilling modules and crew quarters are located on the surface deck. They can drill to depths of about 1,500 feet below the surface but are expensive to build, so they usually require a large oil discovery to justify their construction.
