The reasons for BP Deepwater Blowout failure The oil spill incident took place on April 20, 2010 in the Gulf of Mexico. The Deepwater Horizon was semi-submersible, mobile, floating, dynamically positioned drilling rig that could drill upto 3,000 metres. The Macondo well was the place where the rig was situated which was 41 miles off the Louisiana coast. It caused lives of 11 people on board with a lot of environment damage due to 4,900,000 barrels of oil. After the oil leaking, it damaged the oceans, shoreline nearby and marine life. According to the report, 2,200 tonnes of material which was damaged due to oil spill. Along with this, it affected the marine life which caused many dolphin deaths and tuna and amberjack life shortening results. The rig sank on 22nd April, 2010. There are eight main reasons for the explosion and oil spill: 1. Dodgy Cement The cement was …show more content…

Hence, looking at the test results it can be concluded that there was lack of communication, cement testing was not done accurately, risk management was not done appropriately. The following lack in activities could be warned by the BP Macondo well team. 2. The shoe track barriers did not isolate the hydrocarbons The shoe track barriers consisted of two barriers i.e. the cement and the float collar which was designed to prevent fluid flow into the casing. The shoe track barriers were positioned at the bottom of the casing. The float collar consisted of two check valves and a ported reamer. The investigation team found out the possible failures of both the shoe track barriers. As discussed earlier, the cement failure was caused due to contamination of nitrogen from the nitrified foam cement. The possible reasons for failure of float collar were: • Failure of the check valves to seal. • Failure of the float collar to convert due to insufficient flow rate. • Damage caused by the high

1 The Deepwater Horizon was a drilling rig, which had been rented by British Petroleum (BP), in the Gulf of Mexico. The rig exploded on April 20th, 2010, pouring nearly 5 million barrels of oil into the sea over a three months’ span. This environmental crisis endangered marine wildlife, as well as workers that were injured during the explosion. Of 126 people, 28 workers in total were hurt, leaving 11 that were fatally injured, while the other 17 were severely injured (Crandall, Parnell, & Spillan, 2013).

An example of the Deepwater Horizon oil spill affecting the ecosystem is do to the pollution of the water, the death of fish, and the plants that died from the oil. The reason of the the oil spill is do to the pipe that was cut that contained the oil. Statistics show that the oil spill harmed and or killed approximately 82,000 birds of 102 species, 6,165 sea turtles, and up to 25,900 marine mammals, including bottlenose dolphins, spinner dolphins, melon-headed whales and sperm whales. An incident that lead to the ecosystem collapsing was do to the oil rig having to cut the pipe that pumped the oil, which caused the oil to seep into the sand and the roots of the plants. A fact that shows that the ecosystem was affected is the death of all the animals.

The Exxon Valdez Oil Spill: 27 Years Later Sachin Nair, Biologist, Ph.D. Anchorage, Alaska-- On March 24, 1989, the oil freighter Exxon Valdez entered Alaska's Prince William Sound, a sound off the Gulf of Alaska, after leaving the Valdez Marine Terminal filled with crude oil. At exactly 12:04 am, the oil tanker crashed into a reef, piercing the hull open and releasing 11 million gallons, 41 639 530 liters, of oil into the surrounding marine environment. Emergency responses by the oil company, Exxon, and the Alyeska Pipeline Company were very insufficient to contain much of the spill, while soon after, a storm blew in, spreading the oil vastly across 11,000 square miles of ocean water.

Petrobras had many oil spills in the span of five years. These include, but are not limited to, in 2000, a pipeline spilled oil into the Guanabara Bay (Spector, 2013). This event occurred for two hours before it was discovered. Then, again in 2000, another spill occurred, leaking oil into two nearby rivers. Shortly after that, a drilling platform blew up; in the process it killed 11 employees and again spilled oil into the water (Spector,

From technology perspective, many complex systems were present in the drilling rig including cement testing and modeling software for testing the pressure in the drilling pipes. BOP (Blow out Preventer) inducted on the top of the well for the risk management purpose so that in case of emergency, the well could be cut off the drilling rig and hydrocarbons were unable to reach the rig. Regardless of such advance technologies on

Nonetheless, competitors of Wilkerson overlooked the opportunity to make profit for themselves in flow controllers, due to the fact that Wilkerson has increased the product price by 10% without losing any business. President of the Wilkerson Company was discussing the business’s operating results with his financial controller and manufacturing manager. Reason for this meeting was because; competitors were now reducing the price of their pumps, posing a threat to Wilkerson’s major product line.

I've already noticed that Macondo Prospect was powered by BP, making BP the most interesting company for my research. However, there are other companies that have performed operations to establish this source of oil. BP has leased the Macondo well from Transocean so we can identify Transocean as the owner of the well. BP held only 65 percent of the Macondo prospectus and we can identify the Anadarko Petroleum Corporation and MOEX Offshore as the other owners, with a 25 percent and 10 percent stake in the Macondo oil

Over the past number of years, the most common and well- known method used to drill wells was the Overbalance Drilling method (OVD). Overbalance Drilling is a technique where the bottom hole pressure of the wellbore is kept higher than the formation pressure while performing the drilling process. To maintain an overbalance atmosphere, the mud weight in the drilling fluid needs to be heavier and denser. It is designed to just be above the formation fluid pressure but lower compare to the formation fracture pressure (Akdeniz, 2012). However, everything has its cons.

Deepwater Horizon Explosion and Oil Spill The incident occurred due to the uncontrolled release of pressure from the oil well and the failure of the pressure control system to contain the pressure, thus leading to an explosion. Following which, the oil rig sank on 22nd April 2010 and led to the largest oil spill in the history of petroleum industry. The risk of oil spill could have been reduced if BP had taken the appropriate measures; as reports have stated that BP were aware of the metal casing for the blowout preventer breaking down under high pressure and yet improper maintenance was done to preserve the functionality of the pressure control system. Environmental impact
