The Blowout Preventer, or BOP, is safety equipment designed to prevent uncontrolled flow of formation fluids during drilling and completion operations. During drilling, mud is pumped down the drill string to lubricate and cool the bit, and provide equalizing pressure in the well. If the well’s hydro-static pressure falls below the formation’s pressure, a kick can occur, allowing gas, oil, and salt water fluids to enter the well bore.

The Blowout Preventer is comprised of four main components, stacked one upon another. They are the annular preventer, blind ram, blind shear ram, and the pipe ram. There can be many different configurations, sizes and pressure ratings, dependent on well design, formation pressures, and areas of use. The BOP is attached to the steel casing that is cemented around the well bore. The drill string is suspended through the center of the well bore. This is the rotating pipe to which the drill bit is attached.

These multiple components provide redundancy, and are controlled by a device called the accumulator. This unit can be operated remotely, using a panel located on the rig floor, or by personnel on the ground, using duplicate controls on the accumulator itself.

The second line of defense for the workers and the well to prevent a blowout is the group of equipment called blowout preventers (BOPs). BOPs and associated valves are installed on top of the casing head before drilling ahead after rigging up. These high-pressure safety valves and associated equipment are designed to shut off the well hole and prevent the escape of the underground fluids and prevent a blowout from occurring. After installation, the BOP and associated valves are pressure tested to ensure integrity and proper operations.

A choke manifold is a system of valves used to circulate out a kick and to circulate mud in of the proper weight. This device responds automatically to a kick and can prevent a blowout if properly installed and maintained.

If not properly monitored, changes in pressure that can occur while the well is being drilled can cause combustible hydrocarbons to flow unchecked and at high pressures and flow rates. If this flow of hydrocarbons is not stopped in time, the hydrocarbons can ignite into a deadly firestorm called a blowout. Because of the immense cost and danger associated with oil well blowouts, the bulk of the well control industry revolves around the prevention and avoidance of blowouts. Unfortunately, because a blowout only takes a brief moment to occur, it is necessary that there be methods in place to combat them when the need arises.

In a nutshell, "a blowout is an uncontrolled flow of gas, oil or other formation fluids into the atmosphere or another zone," explained Barry Cooper of Well Control School, an organization, which has offered well control training programs to the oil and gas industry for more than 25 years.

"Blowouts are the most tragic and expensive accidents in the upstream petroleum industry," said Cooper. "They endanger life, the environment and future production from the lost well." On an economic level, an oil well gushing thousands or even millions of barrels of oil is costing a company not only in short term production, but also the long-term profitability of the well itself. It is vital to the profitability of the well that the blowout is stopped and the well put back online as quickly as possible.

Because of their intensity and the very particular circumstances that set blowouts and oil well fires apart from regular conflagrations, unique and specially trained firefighters must be employed to fix them. Myron M. Kinley, the father of blowout control and oil well firefighting, founded the MM Kinley Company in 1923, which set the trend toward an industry devoted to oil well firefighting. By 1946, the famous oil well firefighter Red Adair had joined the company, and by 1959, he had founded the Red Adair Company.

Today, companies like Boots & Coots, which variously spun off from the Red Adair Company, continue in the same tradition. While the technology has improved significantly over the past 85 years, the basic methods and strategies employed to battle blowouts have remained the same.

Most commonly, when a well is lost to a blowout, the drilling package will have collapsed around the well, making proper assessment of the situation difficult. Firefighters arrive as quickly as possible and use machinery to remove the damaged rig and associated debris so they can assess the situation and choose the best method to fight the blowout.

In the early days of fighting oil well fires, the most common technique to smother a blowout was to snuff it with a dynamite blast. Pioneered by Myron Kinley, the intention is to blast fuel and oxygen away from the flame, effectively eliminating the fuel source, similar to snuffing out a candle. Although the first instance of this method dates back to 1913, dynamite blasting continues to be one of the most frequently employed methods.

A more complicated method for bringing a blown-out well under control involves carefully capping the well with a new blowout preventer, or "BOP." BOPs are essentially large valves on the surface of the well that quickly shut off the well as a last ditch precaution to prevent a blowout from occurring.

In this procedure, the detritus of the collapsed rig is carefully removed and a high-pressure abrasive cutter is used to sever the damaged BOP and wellhead for removal. A long boom assembly - at the end of which is a replacement BOP - is maneuvered into position. Large amounts of water are sprayed on the replacement BOP to combat the flames and to keep the replacement BOP from getting too hot. The BOP is quickly lowered onto the well and bolted into place, thus capping the blowout.

Not all blowouts necessarily ignite into towering infernos. Sometimes, the hydrocarbons merely blow into the air, which can actually be more dangerous. Often, firefighters will deliberately ignite the blowout as a precaution.

In addition to other safety issues, concerns for the effects on the environment have become increasingly important over the last 30 years. Companies must be careful to prevent the blowout from leaking hydrocarbons. This is another reason firefighters deliberately ignite a blowout that is blowing hydrocarbons: a burning blowout will consume the leaking hydrocarbons rather than allowing them to blow into the environment.

Blowout control and oil well firefighting are based on tradition and apprenticeship. Advances in technique and technology only underscore the inherent consistency in the industry.

The mishap on the Enoch Cree aboriginal homeland beside the western city limit of Edmonton highlighted the environmental and cultural sensitivity of tapping deposits contaminated with hydrogen-sulphide. The case is liable to provide “some learnings” for the industry and the Alberta Energy and Utilities Board alike, said David Pryce, western operations chief at the Canadian Association of Petroleum Producers.

Acclaim and the AEUB alike emphasized the accident was a small one by industrial standards. The sourness of the gas in question is only 370 parts per million or 0.037%. Flows from the blowout were estimated at 1 MMcf/d or less.

After dousing an accidental fire caused by static electricity generated during initial attempts to control the well, the specialists deliberately re-ignited the gas in order to burn off hydrogen-sulphide while control efforts continued. When incinerated, the substance becomes relatively inoffensive sulphur-dioxide with a milder burned-matches odor. Well beyond the detection range of even the most sensitive nose, the blowout set off public alarm and affected industry fortunes. The Edmonton accident was immediately seized upon as a reason to put a stop to plans for sour gas wells on the southeastern fringe of Calgary by interveners in a case involving Compton Petroleum.

But the Edmonton accident also sent a message that no Alberta location or company is immune against running afoul of sour gas. The mishap involved a routine “workover” to revive and extend the life of a relatively small,aging well that Acclaim Energy acquired earlier this year in a C$433.7 million(US$350 million) purchase of assets across central and northern Alberta from ChevronTexaco Corp. The presence of sour gas nearby in high enough concentrations to cause potential concerns came as news to most Edmonton residents.

Pryce predicted the Edmonton blowout could ultimately become a helpful case history to be dissected and used as a basis for improvements in the field by the Alberta Advisory Committee on Public Safety and Sour Gas, a collaborative agency founded by the AEUB and led by retired chairman Gerry DeSorcy.

Houston, TX-based Cudd Pressure Control was on the scene Friday to cap the well, which began spewing gas at 8:30 a.m. (Mountain Time) Thursday, Reynolds told NGI. The well was flowing gas at a rate of more than 2 MMcf/minute. The owner of the drilling rig was reported to be Chi Operating Inc., also of Houston.

Reynolds said that no one was injured as a result of the well blowout, which occurred about 600 to 800 feet from one of the six fire substations in Carlsbad. New Mexico permits drilling as close as 500 feet from a structure.

He did not know when people would be able to return to their homes and businesses, saying it would all depend on the mitigation work at the blowout site and the weather. Carlsbad is tucked away in the southeastern corner of the state near the Texas border.

The blowout comes about 3 1/2 years after a major explosion on the El Paso Natural Gas pipeline system in Carlsbad, which killed 12 people at a pipeline crossing near the Pecos River.

DICKINSON, N.D. — A few weeks ago, a man walked into Command Center, a temporary labor and staffing service in downtown Dickinson, and said he needed a job after being laid off from a high-paying position on an oil rig.

This is especially true around Dickinson, south of the core drilling area. There isn’t a drilling rig within 50 miles of Dickinson and likely won’t be until the price of oil climbs back to levels oil companies deem profitable.

“There’s less wells coming on with less rigs and less work,” Heim said. “The construction has slowed down a lot for us. ... We’re finding that they’re not fixing the margin of wells at this time. If they have troubles, they’ll shut the wells in and wait until the prices come up to fix them.”

Guy Grooms, one of the co-owners of 4-Corners Hotshot in Dickinson, said his six-person fleet hasn’t felt a big impact because most of their work comes in assisting workover rig crews that maintain producing wells.

Mary Urlacher said there has been an uptick in people coming to her office and looking for employment opportunities after being laid off from oil field jobs. Drilling rig and roustabout workers are those who’ve felt the biggest impact, she said, as well as the truck drivers who serviced rigs. Many positions, she said, are seeing hours being cut.

Today, on the one-year anniversary, Americans don’t have to travel to the Gulf to witness the lingering effect of the the BP Deepwater Horizon oil spill. It’s right there in the numbers on their gas receipts every time they fill up at the pump. As hurtful as the disaster has been to the economic fortunes of the Gulf region, the impact of the Obama administration’s response to the spill has been far worse on the nation’s economy.

On April 20, 2010, the day of the tragic oil-rig blowout that killed 11 workers, the average price for gas nationwide was $2.87 a gallon. Today, it’s nearly a dollar higher. Residents of California, Connecticut, New York, Illinois, Hawaii and Alaska already have seen gasoline crack the $4 mark. If the price at the pump holds to its current trajectory, by Memorial Day, it will surpass the all-time nationwide high of $4.11 set in July 2008. Beyond that, the summer driving season could make $5 gas a nightmarish reality.

The public’s cries for relief from the upward spiral have failed to penetrate the thick walls of the White House, but a federal judge has finally gotten through. Judge Martin Feldman ordered the drilling moratorium lifted in February, and now a few permits are trickling out of the Interior Department. Secretary Ken Salazar and his permit czar, Michael Bromwich, have denied responsibility for the slowdown and even feinted solidarity with oil workers last week by donning hardhats and climbing aboard the first Gulf oil rig to receive a drilling permit since the BP explosion. An estimated 20,000 jobs already have been lost in the regions and oil production is expected to average 220,000 barrels a day fewer than pre-disaster projections.

The investigations by the US Chemical Safety and Hazard Investigation Board (CSB) of the blowout on the Pryor Trust 1-H 9 well and Macondo concluded that both were the result of a failure to maintain the barriers needed to prevent an influx of gas into a well.

In both cases, the board found a series of missed signals, misleading tests, and miscalculations that allowed gas to build up in a well unnoticed, leading to a blowout that could not be stopped by a blowout preventer (BOP). Workers died in both cases—11 at Macondo and five at Pryor Trust.

The Pryor Trust well was an onshore gas well in rural Oklahoma where a blowout destroyed a rig in the morning and the fire was put out that afternoon. There was little media coverage. The environmental impact was minimal, and the companies involved, Patterson-UTI Drilling and Red Mountain Energy, are not well known.

“When the blowout mud and gas ignited, it created a massive fire on the rig floor. All five of the workers inside the driller’s cabin were effectively trapped because fire blocked the driller’s cabin’s two exit doors,” said Lauren Grim, a CSB investigator who noted there is no guidance to ensure that an emergency evacuation option is present.

A tall flare was evidence that drilling was in progress. The Patterson-UTI rig was equipped to safely manage gas produced during drilling, using a rotating control device and an orbit valve to divert mud with gas to a mud/gas separator and on to a flare that ranged from 20 ft high, to as high as 50 ft, the report said.

Low-mud-weight fluid can allow faster drilling and limit formation damage. But after drilling stopped at 3:30 p.m., the rig crew needed to add enough mud weight to stop the gas influx. The calculation of how much mud-weighted fluid to add was complicated by the fact that they were tripping more than 13,000 ft of drillpipe out of the hole.

The report from the US Chemical Safety and Hazard Investigation Board called for expanded regulation of the unique risks posed by drilling. Following the lead of offshore regulations, it is seeking guidance in standards from the American Petroleum Institute (API). The board asked API to expand its recommended practices for onshore drilling to promote:Design improvements to protect those in the driller’s cabin from blowout and fire hazards.

Rising fluid levels in the tanks did not trigger alerts because the alarm system was off. The CSB report explained that a high number of false alarms “likely led to the drillers choosing to turn off the alarm system.”

Alerts were sent when the volume of fluid changed by a set amount—for Patterson-UTI the set point was ±5 bbl. Routine activities while drilling, such as tripping pipe, could regularly exceed that limit, triggering a false alarm.

At 8:35 am, the BHA was removed from the well after testing so they could attach the drill bit. A floor hand told the driller he saw mud flowing out of the open rotating head bowl and then saw that “mud was shooting up steadily, getting closer to the rig floor,” the report said.

The mix of gas and diesel-oil-based drilling fluid from the well ignited and the report said the “fire was massive and intense, engulfing much of the rig floor and the driller’s cabin. It is unknown how long the victims remained alive inside the driller’s cabin, but they had no viable escape routes.”

The floor hand and the rig manager escaped down the stairs to the ground. A derrick hand in the mast “threw his legs around the descent cable and shimmied down the cable toward the ground.”

The rig manager and the company man from the previous shift tried to activate the BOP at the accumulator, which provides the high-pressure stream needed to power the device. The report said they each pulled a series of control handles, but were unable to activate any part of the BOP.
