It was Upstream who first reported on the matter.
the Situation is now stable, and the well is stabilized, ” says Statoil spokesman Ola Anders Skauby to E24.
the petroleum safety authority norway has initiated an investigation and says that the situation is serious.
Statoil has tried to stabilize the depleted oil well on the Troll field in the north Sea after an accident the previous weekend.
the Bellona foundation believes that we have not been in the vicinity of such a serious situation on the Norwegian continental shelf for a long time. The risk of major accident is still significant. Statoil has in no way control and has not provided any information since Saturday. Here it is obvious that something is very, very wrong, ” says Bellona foundation leader Frederic Hauge VG.
Closed well
Then notified the oil company that the rig Songa Endurance experienced a brønnkontrollhendelse when a produksjonsstreng should be pulled out of the well. The well should be plugged, and there was some gas left in the reservoir.
According to Statoil, was well closed around the drill string with the de-sludging valve, or the BOP (blowout preventer), to prevent an accident.
Part of the crew on the rig were evacuated.
– BOP-a stopped the gas from leaking further up from the well. We had a plug and a valve in the produksjonsrøret to prevent the gas from flowing up on the rig, ” says Skauby.
Statoil: – Look seriously at the event
We worked the previous weekend to re-establish drilling fluid-barriers in the well, and have worked to push the gas down in the reservoir, said Skauby.
Statoil has no estimate on how long it will take to remove the gas.
–We want to make this as safe and controlled as possible, ” says Skauby.
the Oil company informs that there is still some gas in the produksjonsstrengen standing in the well, and that they are working with to remove this gas before you can go back to a normalized situation.
Statoil will now investigate the situation, and see it in the context of several other incidents the last time.
” We take these incidents seriously, and mobilized our emergency preparedness to be prepared for the worst possible outcome. So get your investigation show how serious events have been, ” says Skauby.
” Because we have had several events in a short time, we feel that it is appropriate to also refer to them collectively, he says.
Lost control of the well
the de-sludging valve was activated and the well was closed, according to Statoil. At the same time, personnel were evacuated from the platform.
During the operation, put you fixed the drill string and lost contact and control of the well. Large amounts of boremudd was sent down to attempt to achieve stability. In the afternoon went to tom, and new boats are being sent out and should arrive on the evening at 20 time with more boremudd.
the Bellona foundation is familiar with that one since this has been running shuttles with mud and boremudd from the country in six days. Bellona know that you do not have control on the reservoir and that boremudden disappear. It just disappears in the reservoir, and here is the danger of major accident significantly. Borestrenger is still stuck, and you do not have contact and control with the reservoir, ” says Frederic Hauge of the VG.
According to the joint rescue coordination centre Southern Norway was informed of the Songa about the evacuation in the north Sea on Saturday, 15. October at 09.40.
last year, wrote the E24 that Statoil had not met the emissions standards on the Troll field for many years. It led to oljekjempen asked the government to modify the requirements.
107 were aboard
107 persons were on board the drilling rig when the crew detected the gas on the drill floor. When rejected Statoil that it was a gas leak, but said it was found that the minor amounts of gas. A 20-century people were shortly after evacuated to nearby platforms.
Songa do not want to comment on the situation.
I have no comment to this, ” says Songa ceo Bjørnar Iversen to E24.
Ongoing event
the Psa considers the situation on the Troll an “ongoing incident”, and have already started the investigation of what happened on the “Songa Endurance” last Saturday.
the Case continues below the advertisement.
– It is a serious situation, in our opinion. Although Statoil has control, they work still to normalize the situation, ” says press contact Øyvind Midttun in the petroleum safety authority norway to VG.
Three incidents
the petroleum safety authority norway has started the investigation of two additional serious incidents in the last few days: A gassulykke on land at Sture terminal in Øygarden, where six people were injured, and a ranntilløp on the Statfjord A last Sunday.
We are worried over so many events in a short time, but it is too early to say whether there are any fellesnevnere here-. It is something we are now going to look at, ” says Midttun.
