CNOOC Suizhong Oilfield Oil Spill Shut Down &Nbsp; Production Loss Far Exceeds Penglai Project

On the 11 day, the oil tanker operated on the C platform of Penglai 19-3 oil field.

At the same time, ConocoPhillips divers are also cleaning up oil-based mud on the seabed.

In recent months, CNOOC accident continued, a wave of uneven rise again.

Following the fire accident in Penglai's 19-3 largest oil and gas field in CNOOC and the biggest oil refining project in Huizhou, Dayawan refinery project, the central control of the central platform of Liaoning Suizhong 36-1 oil field was damaged yesterday, resulting in the oil falling to the sea and the oil field being shut down.

Oil spill is low, trouble has been eliminated.

Yesterday morning, the marine environmental protection department of the State Oceanic Administration received the 01:30 report of Tianjin branch of CNOOC, and the central control platform of Suizhong 36-1 oil field failed. The whole oil field was shut down, and the crude oil discharged from the flare of the process was released to the sea.

Emergency resources should be used immediately.

Initially estimated that the oil spill volume was about 0.1 to 0.15 cubic meters, and 1 square kilometers of oil film distribution was found in the incident area.

CNOOC Tianjin branch has launched emergency procedures.

The marine environmental protection department of the State Oceanic Administration said yesterday that after receiving the report, CNOOC immediately requested the CNOOC to take effective measures. At present, CNOOC has disposed of oil spill disposal measures such as spilled linoleum and spray dispersant, and arranged for 4 working vessels to carry the corresponding oil spill emergency resources to the scene.

At the same time, the Beihai sub Bureau has dispatched 18 and 21 ships from the coast guard to the emergency area to carry out emergency monitoring and monitoring.

Yesterday evening, CNOOC issued a press release.

The initiative to disclose information

Prior to the 19-3 oil spill accident in Penglai, the largest area of oil spill per day was 158 square kilometers, while the 36-1 oil field in Suizhong only found 1 square kilometers of oil film in the incident area.

CNOOC, a person in charge, told reporters that "0.1 to 0.15 cubic meters is very, very small. It may not even be 1 barrels of oil, which can be said to be a small amount of crude oil thrown out during the operation."

Penglai 19-3 Oilfield

loss

Production loss far exceeds Penglai 19-3

Although the oil spill event in Suizhong 36-1 oil field is far from that of Penglai's 19-3 oil spill, its impact on CNOOC crude oil production is much higher than that of Penglai 19-3 oilfield.

After the 19-3 oil spill in Penglai, the oil field did not stop production, and its impact on the crude oil output of the company was only about 1000 per day, while CNOOC produced about 900 thousand barrels of crude oil a day.

However, the 36-1 oil field in Suizhong is the largest self operated oil field that CNOOC has built and put into operation so far. Its output accounts for about 40%-50% of the annual output of Tianjin branch.

Industry analysis of its daily output may reach tens of thousands of barrels.

CNOOC official said that the output of the oil field is very large. Although the fault has been ruled out, the oil field is still in a state of shutdown, and it is hard to say when it will be able to resume production.

But the person said that if the impact of production is not long, I believe that it has little impact on output. If there is a significant impact, the company will disclose information to the market on the stock exchange.

CNOOC Hong Kong share price fell in recent days, dropping 2.96% yesterday to close at HK $17.68.

Influence

Oil spill in Penglai affects 4240km2 water quality

The area is equivalent to Qinghai Lake, the largest lake in China, of which the four category is 840 square kilometers.

The oil spill accident in Penglai 19-3 oil field not only caused four kinds of serious polluted seawater area of 840 square kilometers, but also led to the decline of water quality around 3400 square kilometers of sea area.

The affected area is 4240 square kilometers, close to the largest lake in China, Qinghai Lake.

The State Oceanic Administration also said that the Beihai environmental monitoring center of the Bureau recently intensified its monitoring, analysis and evaluation of the marine environmental impact caused by oil spill in Penglai 19-3 oil field, Bohai.

The results showed that as of July 11th, the oil spill in the 19-3 oil field in Penglai not only caused four serious polluted seawater area of 840 square kilometers, but also caused the water quality of the 3400 square kilometers of the surrounding area to decrease to third, fourth types of water quality, mainly concentrated in the surrounding waters of Penglai 19-3 oilfield and the northwest waters.

The outer line of the pollution area is 38 kilometers east of Long Island and 61 kilometers west of Jingtang Port.

At the same time, the seabed sediments near oil spill point were polluted by spilled oil and oil-based mud. The sediment quality of the sea area dropped from the first class to third, with an area of about 20 square kilometers.

In addition, since from July 6th to 11th, the sea area of over second types of water quality in Penglai's 19-3 oil field area is about 19 square kilometers, and the pollution area earlier has been greatly reduced.

countermeasure

Yantai fishery sector expands surveillance range

The day before yesterday, the State Oceanic Administration announced CNOOC 19-3 drilling platform again leaking oil.

To ensure timely monitoring of oil pollution trends, Yantai marine and Fisheries Bureau expanded the monitoring point and set up several contingency plans for possible pollution incidents.

After the oil spill, Yantai marine and Fishery Bureau set up monitoring points along the coast of Long Island county.

Yesterday, the reporter learned from the bureau that the scope of the monitoring points has been extended to a few dozen miles away from Long Island county.

During the interview, the official admitted that at present, except for Long Island County, they had received reports of abnormal deaths of marine organisms. However, there is still no evidence that the above incidents are related to the leakage of oil on the 19-3 platform.

Sun Zhaobo, director of the environmental protection section of the Yantai marine and Fishery Bureau, said that after the oil spill occurred, the Bureau set up nine monitoring points in the waters of Long Island and other places. At present, apart from the excessive oil quality of one monitoring point, other monitoring points have not yet found anomalies, but the pollution zone will change along with the changes in ocean currents and wind direction. This pollution zone will have an impact on seafood within its range.

For compensation, Sun Zhaobo said that there is no causal relationship between seafood death and oil leakage.

As for the indirect effects, such as whether the fish population in the sea area has been reduced, and whether the seawater quality has declined, all the relevant departments need to compare and take time and process.

Statement

First, the departments of the marine system and the provinces and cities around the Bohai sea should strengthen coordination and coordination, play chess in the next round, and do a good job in marine environmental protection work around Bohai.

Secondly, all oil and gas exploration and development activities shall be checked and checked, and spot checks shall be conducted on the basis of self-examination conducted by enterprises.

Three, we should further urge ConocoPhillips to take effective measures to find out the causes of oil spills as soon as possible and thoroughly investigate and deal with possible risks.

At the same time, we should speed up the trial of cases.

Four, marine environmental supervision departments should strengthen communication, coordination and cooperation with all coastal departments, and implement various measures.

At the same time, we should pay close attention to the issues of public concern, and publish relevant information impartially, objectively and timely.

unscramble

"Sea and land" go hand in hand at the same time, safety accidents happen one after another.

Target big pressure CNOOC suspected aggressive

Recently, CNOOC's star projects have successively experienced accidents. In the eyes of the public, excellent images, excellent team members and pparent and open information have been subverted.

It is worth noting that at the end of last year, CNOOC completed a "feat", that is, the first breakthrough in offshore oil and gas production of 50 million tons.

In fact, with the continuous production of new offshore oil fields, CNOOC's annual crude oil output has maintained a high growth rate compared with PetroChina and Sinopec.

Data show that the domestic annual output of new crude oil, sea accounted for 50%.

In addition to the sea, CNOOC also actively "ashore", the accident in Dayawan refining project is the only CNOOC oil refinery project.

Last year, the refinery also lost the SIEMENS Russia high speed train project and Shanghai World Expo general construction planning consultation project last year, and won the gold medal of IPMA international excellence project management, which has the reputation of project management "Oscar". PK

"It is impossible to completely eliminate the accident, but the scale of CNOOC is getting bigger and bigger, and the probability of its accident is certainly getting bigger and bigger, which requires CNOOC to improve the safety of production and management in an all-round way."

Lin Boqiang, director of China Energy Research Center, Xiamen University, told reporters.

CNOOC insiders also revealed that in order to achieve 50 million tons of oil and gas production, all oil fields are full of strength, the pressure of various production units is very large, to a certain extent, did increase the risk of safety risks.

A staff member engaged in safety production in a petroleum company told reporters that the oil and gas industry is a high-risk industry and an accident prone area. A big medal is no longer a safety card. Any slight loss may lead to an accident or even a major environmental disaster. How to look for experience and lessons from every accident is a test for an enterprise and an important index for measuring the management level of an enterprise.

It is understood that at present, CNOOC also announced the ambitious goal of building another Daqing oil field in the deep sea. This safety card is not to be relaxed at all times.
