One-Third of U.S. Oil and Gas Reserves are Located in Harvey’s Path

Hurricane Harvey is anticipated to strengthen to a category 3 storm as it reaches the Texas coast tonight through early Saturday, bringing high winds, coastal flooding, and torrential rains. Some areas could see 30 inches or more of rain —  the amount these coastal cities normally get in a year.

After hurricanes Katrina and Rita, we saw leaks and spills from dozens of pipelines and platforms offshore, and from damaged coastal facilities, that cumulatively amounted to at least 9 million gallons of oil. After Ike and Isaac, we saw similar leaks from drilling sites, processing and storage facilities, and petrochemical facilities inundated by flood waters resulting from sustained heavy rainfall. Forecasts for Hurricane Harvey suggest we may see similar problems as it moves ashore.

Christian developed the following map using Carto to show just how much oil and gas infrastructure is in Harvey’s projected path (in red). The green points below represent offshore platforms. The gray lines are pipelines.

Map Legend: The black points on the map are Forecast center locations for Hurricane Harvey, from NOAA’s National Hurricane Center. The red area shows the potential track area, from NOAA’s National Hurricane Center, the red path is the forecast path, again from NOAA’s National Hurricane Center The green dots represent offshore platforms, and the gray lines are pipelines, data from BOEM.

The black points on the map are the forecast center locations for Hurricane Harvey for the next few days, from NOAA’s National Hurricane Center (data downloaded at 2pm ET on August 24).  The red path connecting those dots is the predicted track of the storm.  The larger area enclosed in red shows the potential track area, indicating a high degree of uncertainty as the storm is predicted to stall over the coast after making landfall late Friday.  The green dots show the locations of offshore oil and gas platforms, and the gray lines show seafloor oil and gas pipelines; data from BOEM.

Satellite Imagery Reveals Scope of Last Week’s Oil Spill in Kuwait

A large oil spill was reported on August 10th off the southern coast of Kuwait near the resort community of Al Khiran. 

Imagery and Analysis

Sentinel-1 satellite imagery collected on the day of the spill shows a slick that covers 131 square kilometers. Based on our conservative estimate, assuming the slick is on average only 1 micron (1/1,000th of a millimeter) thick, this slick holds at least 34,590 gallons of oil. Early media reports of 35,000 barrels (=1.47 million gallons) seem far too high, based on how quickly the spill broke up and dissipated. 

Sentinel-2 multispectral satellite imagery collected on August 11 shows oil washing up on shore near Ras Al-Zour just north of Al Khiran, and Sentinel-1 imagery collected on August 14 shows remnants of the slick drifting along the coast to the north of Ras Al-Zour.

While the source and cause of this spill is uncertain, some have suggested it originated from a tanker offshore. Other reports speculate it is linked to the Al Khafji offshore oil field being developed by Kuwait and Saudi Arabia, which has pipeline infrastructure which runs to the shore. Operators deny the spill originated in their field.  At the same time the slick started, a pipeline laying vessel, the DLB 1600, was moving through the area. AIS data reveal this huge offshore construction vessel has been slowly moving eastward towards the infrastructure in the Al Khafji field for the past week, and on the 10th the DLB 1600 is visible on the Sentinel-1 image near the north end of the slick. One possibility we haven’t seen mentioned yet is the pipelay operation damaged some existing infrastructure on the seafloor — for example, an old pipeline still holding crude oil. The potential for anchor-dragging by the pipelay vessel to cause this type of damage is mentioned in this article describing plans to upgrade the DLB 1600 by installing dynamic thrusters; we don’t know if this upgrade has been implemented yet. By the 14th the DLB 1600 had closed to within 9 km of the Al Khafji field.

A second slick north of the first spill was reported today not far from where a huge $30 billion new oil complex is being built. Check out Business Insider’s short video for more context. We will update this post as new information becomes available.

ENI — Italian Firm Recently Approved for Offshore Exploration in Alaska — Responsible for Last Week’s UK Oil Spill

Blobs of oil and balls of tar washed ashore in northwestern England last week. The oily litter impacted a 15 kilometer stretch of coastline and originated from an OSI (offshore storage installation) that receives oil from the Douglas Complex, an offshore triple-platform central to the Liverpool Bay oil and gas production operations seen below.

The Douglas Complex is integral to the Liverpool Bay’s network because all oil and gas collected by its four satellite sites (Lennox, Hamilton, Hamilton East, and Hamilton North) is funneled through the Complex for processing. Natural gas products are then re-directed ashore to the Point of Ayr Gas Terminal and crude oil to the OSI. It was this latter-most connection, an oil tanker anchored in place, that failed in Liverpool Bay on July 10, 2017.

Radar imagery from  ESA’s Sentinel-1 satellite appears to show the slick resulting from this spill, as it drifts away from the storage tanker and heads toward shore. ASCAT satellite-derived surface wind data from the time of the spill confirms the wind was blowing from the north and east, consistent with the trajectory seen in these images. A spokesperson claimed that between 630-6,300 gallons of oil leaked; our conservative estimate, based on the size of the slick and an assumed average thickness of 1 micron, show this to be at least 6,843 gallons. Also note the half-mile gap between the OSI and a safety response vessel, the Vos Inspirer, on July 11 in the image that matches AIS vessel tracking data. An educated guess would be that the leak originated under water, potentially from the pipeline leading from the Douglas Complex, from the riser pipe from the seafloor to the OSI, or from the seafloor junction between the two.

U.S. Arctic Offshore Energy Policy Context

ENI, the Italian oil firm that accepted responsibility for the Liverpool Bay oil spill was recently granted access to drill for oil in US waters in Alaska’s Beaufort Sea. This approval comes on the back of President Trump’s executive order that recently reversed a permanent ban on new offshore drilling.

The policy change has faced substantial criticism from environmental heavy-weights, culminating in a lawsuit filed by Earthjustice, NRDC, Center for Biological Diversity, League of Conservation Voters, REDOIL, Alaska Wilderness League, Northern Alaska Environmental Center, Greenpeace, Sierra Club, and The Wilderness Society to challenge the executive order’s legality.

Risk, Risk, Risk.

Beyond legal concerns, one would be remiss not to acknowledge the intrinsic risk of Arctic drilling. ENI reported the UK spill to be up to 6,300 gallons, and this took place in a very favorable location for clean-up. But experts agree we are ill-prepared for an oil spill in the markedly less forgiving conditions of the Arctic. The head of the U.S. Coast Guard, Adm. Paul Zukunft, recently commented on the topic by saying:

We saw during Deepwater Horizon, whenever the seas are over four feet, our ability to mechanically remove oil was virtually impossible…Four-foot seas up there [in the Arctic] would probably be a pretty darned good day, so certainly environmental conditions weigh heavily in addition to just the remoteness.”

ENI might learn from Shell Oil’s failures. Shell canned a $7 billion offshore drilling project in Alaska’s Chukchi Sea after determining it was not financially worthwhile. Economic risk factors are furthered by International Energy Agency reports of an oil-supply “glut” and lowering crude prices amidst the rise of both renewable energy, and cheaper oil produced by fracking onshore.

Between supply-side risk, threats of lawsuits, and low oil prices, ENI is diving head first into a complicated, high-risk pool. Off the Fylde coast, authorities were quick to execute a plan after locals immediately brought the situation to their attention. As the Coast Guard continues to advocate for the basic resources needed for emergency preparedness and response in the Arctic, is this a gamble worth taking?

Persistent Oil Leak in Australian Waters Now Disclosed One Year After It Occured

Last week the Guardian reported on an oil spill on Australia’s North West Shelf that was detected in April 2016 but had not been made public until a performance report was recently issued by Australia’s National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA). Despite the spill being estimated to have gone on for two months and released 10,500 liters of oil the Guardian reports that NOPSEMA declined to reveal exactly where the spill had occurred or which company was responsible.

We had a look at operations currently in the area and identified a vessel which fits the description in the article. This is the FPSO OKHA operated by Woodside Energy. Our identification has now been confirmed as Woodside has admitted responsibility and the OKHA has been named as operating at the site.

Though this is being reported as the largest offshore leak in Australian waters last year Woodside states that the spill had no lasting impact on the environment.

On April 15, 2016 two likely response vessels appeared at the leak site. To the west is the dive support vessel Seven Eagle. About 900 meters to the east is the Nor Australis, an offshore supply vessel equipped with a ROV for underwater surveying.

We have examined imagery of the site from April 15th of last year, that is shortly before the OKHA returned to this location and around the time the leak was apparently first detected. Two response vessels appear at the leak site. The Nor Australis is an offshore supply ship equipped with a ROV which probably detected the leak. The dive support vessel Seven Eagle is a short distance to the west. We don’t see any signs of a slick in this image or in several others we checked. However it is still of concern that the report of an incident like this would be kept from the public for more than a year.

 

 

More Oil Spotted at the Taylor Energy Site

We posted about a slick emanating from the Taylor Energy site on April 28th. And surprise, surprise a mere 12 days later, what should we see but yet another slick.

In 2008 Taylor Energy set aside over $600 million to pay for work related to the chronic leak that we have covered extensively since it came to our attention in 2010. As you can see in this image collected by the European Space Agency’s Sentinel 2 satellite, as well as in numerous other images we have collected, their work to date doesn’t seem to have stemmed the leak.

Which begs the question: why is Taylor suing the government to return the $432 million remaining in trust? That money was set aside for work that is yet to be finished. Why would they think they have earned it back?
