@Remi,

154 POB, on a single wellhead? Pls expatiate.

All but two of the 154 workers on the rig and a nearby support barge were evacuated and treated on a nearby platform. They were expected to be taken ashore on Monday evening.

@surveycash: That is an offshore rig, obviously, they are at end of drilling phase, so you would have both Drilling and completions crew on the the rig. Also due to harmmartan, it is possible you have personnel over flow because of helicopter delays or having personnel on the rig days before their operation. It is cheaper to keep personnel longer the rig than having downtime due to inadequate or non availability of required expertize. I hope I have communicated.

Pls house who knows the exact location of OML 86. I've been searching for a higher resolution map of Nigeria's concessions and licenses all day.

that is former texaco field, somewhere offshore bayelsa / delta state.

Not funny people.

Remii, I read on the news that it was a gas kick on an exploratory well, it probably wasnt handled well.
Any details on why it couldn't be contained? How do they intend to stop the fire?

until official report is out, you can only speculate. gas kick expands as it moves to surface as the volume double with half TVD distanced moved upwards (from gas law PV=K), if not detected of released in a controlled manner, it could lead to explosion on surface.

Killing: One option is drilling a relief well into the same wellbore with another rig to pump in kill mud. The well could also die on its own if the reservoir got depleted.

I may be wrong but this is from google.

Not sure u wld want to wait for an unquantified gas reservoir to deplete in this case. Plus mobilizing another rig to drill the relief well will involve some lead time. I just hope it doesn't escalate into an environmental disaster before they sort it out.

^^ you already have a disaster in your hand, it does not get worse, you can only prevent disaster before it occurred. there is fire burning on water that is all you have now, for sure it can not dry up the sea. as for relief well, it takes the same amount of time and tech to drill all wells in the same drilling zone, so you don't expect that to happen in less that 6 weeks, depending on depth of target and the ability of the directional drilling company to hit the well bore on first  attempt.

OML 86 is arrowed in black

transocean has been contracted to drill the relief well

Yay! Nice one guys. Glad we still have intellects on nairaland. Some site (nigerian) said the incident was triggered by maintenance work going-on on a nearby barge and they were bringin up all the conspiracy theories. The good thing is this well is just a gas well, imagine if it had oil with it, we would have been dealing with an environmental disaster. I guess chevron personnels wouldn't have been much on the rig. Does anyone kno about other operating firms with personnels on the rig?

^^^in regards to the oilspill - reports suggests the quantity of spill is in d region of approx 13barrels.

Probably condensate from the gas. It would probably vaporize on its own.
They are really lucky this was not an oil well,

maybe the environment is. but this is a great loss, especially for the families of 2 or 3 persons still missing. this a brand new rig, less than 2 years out of shipyard, owned and run by a Nigerian company. This is not a good for development of Local Contents initiatives.

d search for d missing men has been suspended

UPDATE AS AT 20/1/12
Chevron has discontinued the search for the 2 missing workers and they are now presumed dead. Work has begun to drill a relief well to kill this well and will take some time. Below are satellite images taken today over the rig fire location. Oil on the surface is now clearly leaking from the well.

I wonder if the FG (Dept of Petroleum Resources) is taking any action regarding this incident.

Two weeks gone and this rig is still burning.

Close out on this thread. Heard the fire quit on its own while a relief drilling campaign was mobilised. The well has since been killed, plugged and abandoned. No major environmental issues as it was a gas well, the condensate either burnt or was vaporised. 2 missing ppl from the incident were never found. May they rest in peace.

Hi, my name is Jonathan and I am a litigation assistant for attorneys in California who represent persons in the nearby coastal communities for damages suffered because of the KS Endeavor explosion.

We are interested in talking with anyone who may have information about what happened before, during and after the explosion, both in terms of what caused the blowout, and what pollution and other materials were released into the surrounding waters as a result.

If anyone out there has information on this tragedy, please post a reply to this thread and provide a way for me to get in touch with you. Or you can send me a direct message via the Nairaland website.

We will guarantee confidentiality if requested.
