TheOilDrum.com shelburn comment re peak oil and ASPO

Thursday, June 3rd, 2010

This is such a perfect little summation. Background: shelburn operates ROV vehicles, or works in that part of the oil drilling industry. With the Deepwater Horizon blowout, he started posting a lot more, along with ROCKMAN at theOilDrum.com

There’s some really major statements made here in a comment he made today, and I think you should really give them some thought.

I’ve added in links to the relevant sites he mentions here, and included some explanations to make it easier to understand if you are new to these concepts and groups.

I have lurked around this site (theOilDrum.com) for about 4 years and finally signed up after I went to the APSO (sic, he means ASPO) (Assocation for the Study of Peak Oil) meeting last fall. Never really posted until this past month.

I have now advanced to the point of actually donating, something I never do in real life.

But this site is a beacon of reason and responsible discourse on energy matters that are either ignored, manipulated or totally misconstrued by the media and politicians and poorly understood by the general public.

Hopefully in some small way we can help spread the word about the end of cheap oil and prepare people for the coming transition.

My heartfelt thanks to Gail, Heading Out, Nate, Leanne, Prof Goose and all those listed on the right hand column, not to mention the posters who have provided me with a free education for the past few years.

I would encourage those who are just discovering TOD to help support this effort which is dependent on volunteers and your donations

The guys in the oil fields know peak oil is here now, the only ones who are still in denial are the American people as a group and a lot of politicians who cannot figure out a way to tell them this information without immediately ending their political careers.

shelburn joins an expanding line of petroleum industry insiders, geologists, and engineers, who understand that declining prodution rates are not some future event, they are here now, and are happening all over the world, and the race to maintain our present oil production levels globally is just not doing very well.

If you need a reminder, here’s one:

Less than four months ago, the United States Joint Forces Command (USJFCOM) issued a dramatic warning in its 2010 Joint Operating Environment[1] report about an event that is likely to change the world we live in:

By 2012, surplus oil production capacity could entirely disappear, and as early as 2015, the shortfall in output could reach nearly 10 million barrels per day.[2]

BP LRMP Video – Top Hat Deepwater Horizon Blowout Capping

Thursday, June 3rd, 2010

In case you’re wondering where this is all at.

The riser pipe tube was cut at about 100 ft or so from the BOP unit, then they tried to saw with the diamond band saw device the riser tube from the top of the BOP, but it got stuck and the diamonds wore out, so then they cut the riser pipe a bit above the BOP, which makes creating the seal between the below device and the BOP device a bit harder.

The LMRP Cap preparation work and installation is proceeding as planned. Today the riser has been cut. The LMRP Cap will be in place later in the week. To help understand this process the following videos are available.
Lower Marine Riser Package (LMRP) Cap

I couldn’t get the video to load right on this page, sorry, so just click to watch the LRMP video

And that’s where it stands right now.

You can also watch all the live underwater cameras on one screen at mxl.fi/bpfeeds2. That’s pretty cool.

How the Top Hat method works

Here shelburn from theOilDrum.com explains how the top hat works

Repost from previous thread

It is obvious that most people do not understand the basics of how the top hat is supposed to operate. And BP, per usual, has not thought it necessary to explain anything.

The Top Hat Seal

For a number of reasons the top hat seal is NOT a pressure seal. It is designed to try to keep seawater out, not to keep oil in.

Let me repeat – The top hat seal is NOT a pressure seal. It is designed to try to keep seawater out, not to keep oil in.

BP Deepwater Horizon Relief Wells

Monday, May 31st, 2010

Before you say to yourself, oh, this will all be fine, consider the complexity of achieving success with relief wells. As this author has already noted, it can take many weeks to mill through the original well casing once the relief well intersects it at around 18k feet. And that itself is hardly guaranteed, these wells are hard to drill, and frequently fail.

This guy considers, if the first relief well succeeds, a target date of around September to be realistic, and August to be too best case to be considered as a real goal. And that’s IF and ONLY IF the first well A: intersects the existing well, and B: doesn’t fail in the process.

In the Ixtac blowout, it took 10 months and numerous relief well attempts before they succeeded.

Here we have another oildrummer drilling guy, aliilaal, explaining a bit about why Relief Wells (RW) are so complicated. Keep in mind that the relief wells are what will actually fix the problem, everything else is just a stop-gap measure.

idle thoughts on problems in hitting the target with RW ….had said my 2 cents on wellbore surveys and now form the RW standpoint there are some things to consider with regards to RW target

1- like i’d said ….current technology’s theoretical limits can hit a 10ft radius ball with a confidence interval of 90%…this limit applies on RW with with a grain of salt since expected interception is 18000 rkb ….but really depth can be +- 50 ft on depth …the problem here is azimuth of RW (think 3d geographical grid) ….so essentially the target for the RW is not a circle but a rectangle (in cross sectional view of leaking well when looked at from right or left) of approx 75′ (length) x 2′ (width)

2- now there are two options to establish pressure communication b/w RW and LW (leaking well)…(1) mill into the LK csg or run a hot tap (pull along LK and run a perf gun)….high pressures will likely preclude a hot tap and most likely it will be the milling option

Now Imagine Trying to Handle an Arctic Deep Water Oil Blowout…

Monday, May 31st, 2010

Ok, so we’re reading up on the BP Deepwater Horizon oil blowout, we’re impressed by all the technology and resources being thrown at the problem. And it is in many ways very impressive, all those drill ships, and other deep ocean oil service vendors, ROV (remotely operated vehicles) control ships, pumping ships, etc, all lining up as they are requisitioned from other oil drilling activity in the Gulf of Mexico.

But the really scary thing is to contemplate this blowout up in the Arctic, where the next wave of deep water drilling is set to take place, and that’s what I suggest you start doing. Imagine having to move all these spill recovery and containment resources, drill ships, etc, up to the Arctic, it’s almost impossible to visualize, primarily because… well because it simply would not be possible to do this type of recovery effort up there.

On May 14th, I called Robert Thompson, the current board chair of Resisting Environmental Destruction on Indigenous Lands (REDOIL). “I’m very stressed right now,” he told me. “We’ve been watching the development of BP’s oil spill in the Gulf on television. We’re praying for the animals and people there. We don’t want Shell to be drilling in our Arctic waters this summer.”

As it happened, I was there when, in August 2006, Shell’s first small ship arrived in the Beaufort Sea. Robert’s wife Jane caught it in her binoculars from her living-room window and I photographed it as it was scoping out the sea bottom in a near-shore area just outside Kaktovik. Its job was to prepare the way for a larger seismic ship due later that month.

Since then, Robert has been asking one simple question: If there were a Gulf-like disaster, could spilled oil in the Arctic Ocean actually be cleaned up?

Improper Oil Booming on BP Deepwater Horizon Blowout?

Monday, May 31st, 2010

You might have come across this ‘Fucking Booming’ by FishGrease, but in case you haven’t, here’s a snippet and a few pictures to give you the idea:

Generally, boom is long and bright bright orange or yellow. It is not bright bright orange or yellow so you can see it, dear fledgling boomer, but so Governors, Senators, Presidents and The Media can see it. It has a round floaty part that floats, and a flat “skirt” that sinks. A RULE: the floaty part never floats high enough and the skirt never rides low enough. Some oil will ALWAYS go over the boom and some will ALWAYS go under it. Our task is to MINIMIZE both! We do that by fucking proper fucking booming. Here. This picture teaches you almost 100% of what you’ll learn in DKos Booming School, about fucking proper fucking booming:

proper booming

I lost my one copy of Photoshop, had to learn Gimp, and so the quality is sorta piece-of-shit-c*nt, but you get the idea. It’s fucking obvious. Boom is not meant to contain or catch oil. Boom is meant to divert oil. Boom must always be at an angle to the prevailing wind-wave action or surface current. Boom, at this angle, must always be layered in a fucking overlapped sort-of way with another string of boom. Boom must always divert oil to a catch basin or other container, from where it can be REMOVED FROM THE FUCKING AREA. Looks kinda involved, doesn’t it? It is. But if fucking proper fucking booming is done properly, you can remove most, by far most of the oil from a shoreline and you can do it day after day, week after week, month after month. You can prevent most, by far most of the shoreline from ever being touched by more than a few transient molecules of oil. Done fucking properly, a week after the oil stops coming ashore, no one, man nor beast, can ever tell there has been oil anywhere near that shoreline.
