A 16 Year Oil Spill
And the Fight to Contain It

A 16 Year Oil Spill And the Fight to Contain It

In 2004 Hurricane Ivan created an underwater mudslide that toppled Taylor Energy’s oil platform Mississippi Canyon 20 (MC20) in the Gulf of Mexico (~ 12 miles from the mouth of the Mississippi River) Over the next 16 years, this spill has reportedly become the longest running oil spill in the history of United States and perhaps the largest to date. Conservative estimates put the Taylor Energy MC20 spill at millions of gallons of oil released, a figure that Taylor Energy contests.

Taylor Energy sold its oil and gas assets four years later (minus the leaking wells, which they had a legal responsibility to address) and ceased all drilling and production operations. The MC20 platform’s well conductors were left buried beneath the mud and sediment.

Since the initial incident, multiple scientific studies were conducted by federal and industrial experts.  Federal officials directed Taylor Energy to remove the platform deck and sub-sea debris, decommission the oil pipeline,  contain the leaking oil, and plug and abandon the wells.

For years, Taylor Energy’s attempts to design, construct and install a viable containment plan have failed. Taylor also underestimated the impact of the spill despite a ten-mile sheen. Captain Kristi Luttrell, Federal on Scene Coordinator (FOSC)  took the bold step in 2018 of issuing Taylor Energy a Partial Notice of Federal Assumption and assumed authority for containing the oil. She also put out a comprehensive national Request for Proposal (RFP) for a contractor to safely capture the oil.

In April of 2019, a federal judge denied Taylor Energy’s demand that the U.S. Department of Interior return Taylor Energy money remaining in trust – some $432 Million – a trust that was established in 2008 and earmarked for 'decommissioning' Taylor’s leaking oil field.

Almost 15 years after the spill began, in November 2019 Louisiana-based Couvillion Group, L.L.C (“Couvillion Group”) was selected for the job of containing the spill by the U.S. Coast Guard in a national Request for Proposal (RFP) process. Couvillion was able to begin safely capturing and  bringing the oil to shore In April of 2019.

One of the first actions of the Couvillion Group was to perform a detailed survey of the site.  During this survey, underwater video  footage captured the extent of the spill. What Timmy Couvillion, a seasoned fishing captain, engineer and Louisiana  outdoorsman, saw gave him chills. A seemingly endless view of oil globules with amberjack and other marine life swimming amongst them.

The system that the Couvillion Group created consists of a unique 40-by-40 feet containment structure that was lowered from the deck of a support vessel, and secured to Taylor Energy's downed platform jacket, and suspended about 7 feet above the source of the leak to prevent the system getting clogged. The containment system contains multiple sub-sea storage units to hold the oil until periodic, scheduled retrieval or “pump off.” As of September 1, there have been 20 pump offs, with pump off reports being publicly available after each one. View pump off reports below.

The Couvillion Group’s tally of oil recovered reached 198,000 gallons in the first 6 months of collection (an average of 1075 gallons per day). Taylor Energy’s response to this remarkable engineering accomplishment was to sue the U.S. Coast Guard and Couvillion Group, incredibly asserting that containment actions would make the problem worse.

In a comment made to the Washington Post, the Federal On Scene Coordinator for the MC20 site, Captain Luttrell, lauded the custom-built containment invention, saying: “I’m in awe of what they did. We gave them a task and they did it, and they should be very proud of what they’ve done.”

As of August, 2020, over a half million gallons of oil with less than 1% water have been collected and recycled from the MC 20 site. This quantity is substantially more than what Taylor Energy had reported to the NRC (National Response Center). Without Couvillion Group's containment system this oil would have continued to contaminate the Gulf of Mexico.

The Issue

Louisiana, the United States, and the rest of the world are dependent on oil and gas. The oil and gas community has played a significant role in creating jobs, supporting our culture, and lobbying Washington to bring home hard-earned royalties to support the rebuilding of our coast. While oil spills are low probability, they have the potential to be high consequence. The people of Louisiana know better than most what a major spill can do to impact their way of life. A spill can wreak havoc on the environment, outdoor recreation, marine life and the economy. Spills also have a negative impact on the responsible party – their reputations, their bottom lines, and their ability to operate given the new regulations that typically arise from significant spills. From OPA 90 after the Valdez to the new regulations after the Horizon spill, running oil and  gas projects becomes more challenging for all parties when one company makes a significant mistake.


The Taylor Energy spill has lasted almost 16 years and, by some estimates, is on track to be on par with the Deepwater Horizon spill in terms of volume While every other oil and gas company that does business in Louisiana – or anywhere in the United States - is required to launch a full force and highly regulated effort to clean up any spill of consequence, Taylor Energy’s efforts to contain the spill and stop the pollution were unsuccessful until 2018, when the US Coast Guard, under Federal On Scene Commander (FOSC) Captain Kristi Luttrell, given the unavailing response by Taylor Energy, and armed with data conducted a nationwide search for a highly technical, safe solution to this long term spill.

After over a decade of slow response and failure to stop the flow of oil into the Gulf this could be seen as warranting the imposition of severe penalties and fines by the Federal Government. The United States has filed a counter-claim in a federal proceeding in Washington D.C., seeking assessment of substantial fines and penalties against Taylor Energy.


General Russel L. Honore
Relatedly, on October 23, 2020, the United States sued Taylor Energy in Federal Court in New Orleans, seeking to recoup all sums expended in Couvillion Rapid Response Containment job. This suit also seeks penalties against Taylor Energy.

Resolutions to Council

Louisiana's coastal parish councils have weighed in on the MC20 oil spill, creating resolutions in support of the efforts of The Couvillion Group to safely capture the oil before it enters the waters of the Gulf, and to encourage the continued oversight of the Taylor Spill by the United States Coast Guard and the Bureau of Safety and Environmental Enforcement with an eye toward a permanent solution to this ongoing event. Taylor Energy is considered to be an outlier to the oil and gas industry, which plays a vital role in energy supply and jobs creation, while Taylor allows its only asset to remain a threat to coastal communities and the environment.

The Opportunity

There is more work to be done to fully plug and abandon these wells per federal law. The plug and abandonment will benefit the environment, the shipping industry (the site is in a well-traveled shipping lane, meaning that ships have had to travel through oil for almost 16 years) and the marine life that have been swimming through this oil.

This spill - and the responsible party’s lack of commitment to properly addressing it - is a black eye for an industry that is vital to our state. This spill must continue to be addressed aggressively, as an example of the commitment of regulators and the oil and gas industry as a whole to responding responsibly to incidents.

Permanently plugging and abandoning these wells per federal regulation will send a positive message that even the most complex problems can be solved. 

Most importantly, lessons learned from the successful resolution of this situation can be applied to future low probability, high impact events.


In November, 2018, the Federal Government hired a local Plaquemines Parish contractor, Couvillion Group, LLC (“Couvillion”) to take steps to arrest or mitigate the pollution. The Couvillion team designed and installed a Rapid Response Containment System. The system is a marvel of underwater engineering, design and construction; since going on line in May, 2019, the system has captured and removed more than 500,000 gallons of hydrocarbon pollution which otherwise would have flowed into the Gulf.

Taylor Energy from the outset objected to Couvillion’s involvement. Taking the position that it was more sound and safer to leave the site alone, and repeatedly publishing unrealistic and dubious estimates of oil pollution rates far lower than the actual discharge rate, Taylor Energy sued Couvillion in Federal Court, incredibly claiming among other arguments that Couvillion, by affixing its containment system to the sunken platform, was trespassing on Taylor Energy’s downed jacket, which had laid abandoned on the seabed for nearly 14 years.

Couvillion sought dismissal of the Taylor Energy federal suit by moving for summary judgment. The thrust of Couvillion’s argument was that it was entitled to two types of federal governmental immunity as a contractor working under the authority of the government in an attempt to arrest an environmental calamity. Taylor Energy filed multiple opposition memoranda in an effort to maintain this action, notwithstanding the Herculean effort by Couvillion, and the related success in addressing Taylor Energy’s pollution problem.

On August 21, 2020, United States District Judge Greg Gerard Guidry, granted Couvillion’s motion and dismissed Taylor Energy’s suit against Couvillion, with prejudice. In its erudite ruling, the Court held that Couvillion had proven beyond dispute that it was working under the authority of the government in addressing this ongoing pollution crisis and was immune from the claims asserted by Taylor Energy.

Judge Guidry’s dismissal with prejudice of Taylor Energy’s claims against Couvillion is a victory for the community at large as well as our marine environment, as removal of the pollution containment system would cause renewed pollution of pristine Louisiana and adjacent Federal waters. This ruling confirms protections afforded contractors hired by the Government and authorized by the Government to assist in pollution cleanup and avoids the chilling effect of intimidation by lawsuit.


Couvillion designed, fabricated, and maintains a Rapid Response Solution at the MC 20 site under the direction of the USCG to collect oil that would otherwise be released into the Gulf of Mexico. The system includes a subsea collection dome supported from the downed jacket lying on the seabed. The dome (shown in blue color below) was placed on a porch structure that was cantilevered off the jacket leg directly above four hydrocarbon plumes emanating from the seabed. The collected hydrocarbons are routed to a subsea separator (shown in light color) that separates the oil from the water and gas. Oil is sent to subsea oil containment vessels (shown in red) on top of the jacket. Offloading is accomplished via submersible hydraulic pump on a monthly basis to a surface vessel where the crude is then transported to shore and recycled.

MC-20 Federal Administrative Orders to Taylor Energy

When an oil spill occurs a complex federal framework of laws, executive orders, and regulations govern oil spill response, and permanently shutting down the cause of the spill.  This federal network expands when assessing the civil penalties and assessing environmental damages.  Specific federal government agencies are tasked with various aspects of the environmental incident.  The United States Coast Guard (USCG) is the lead response agency for the recovery and response stage of oil spill in coastal waters.  The US Department of the Interior (DOI) delegated oversight of oil spill planning and response to BSEE, which promulgated regulations governing oil spill response requirements found at 30 CFR part 254, Oil-Spill Response Requirements for Facilities Located Seaward of the Coast Line. The Bureau of Safety and Environmental Enforcement (BSEE) coordinates closely with the U.S. Coast Guard to determine how to effectively respond to incidents and to determine which agency will take the lead in the investigation.  The federal administrative orders provided have been specifically issued to Taylor Energy following the MC-20 Platform collapse and continuous leaking since 2004.  This orders are issued based on federal laws authorizing both USCG and BSEE’s roles in an oil spill based on extensive environmental policy and law including the Oil Pollution Act (OPA) of 1990 (33 U.S.C. §§ 2701 et seq.)”
