some NEAT old video of Rolligon in this LINC:

The LINC at the top of Post # 332 has outrageous, older video footage, including driving the machine over a person. I also stand corrected, aparently they CAN navigate difficult terraine, contrary to my earlier posting.

That is just COOL!. I want one :)
 
Most of the rolligons are back from making their remote delivery. Between 15 & 20 Million$, for the 10 machines in these 2 photos.

Your gonna love the next story: THE CONDOR'S NEST
 
If anyone is looking for some we have three for sale ......... way under 1.5 million not even close. but not near as big either I will get the photos
this is the Baby as it is very small in comparison to the the others they all float

Alaska's Mt. Redoubt volcano erupted several times late Sunday and early Monday, sending an ash plume nearly 12 miles into the air, the Alaska Volcano Observatory reported.

The Anchorage Daily News reported that a fifth eruption took place at about 4:30 a.m. Alaska Daylight Time (AKDT), or 8:30 a.m. EDT.

The National Weather Service detected ash from the fifth eruption at 60,000 feet, far higher than most commercial jetliners fly.

Fine gray dust was falling Monday morning on small communities north of Anchorage, though the state's largest city itself was spared.

"It's coming down," Rita Jackson, 56, said early Monday morning at a 24-hour grocery store in Willow, about 50 miles north of Anchorage

The "Shared Services flights", BP/Conoco/Phillips 737's on the very first post of this thread, got turned around in mid flight, and went back to Anchorage this morning. So some unhappy Oilworkers are stranded at the Anchorage Airport, and some even Unhappier folks didn't get to go out on R & R!

PIPELINE! It's finally warmed up enough for the Pipeline construction crew to go back to work. It's -22, -41 with the windchill but rapidly warming. These first 2 pictures are of a side Boom Pipelayer and a "Caribou Shack" the welders hut. The pipe has already been welded and is getting coated and insulated here. Today is March 23, 2009.

The smaller pipe is "Water-IN", for water injection INTO the oil formation. The larger pipe is Oil Out from the wells. This system serves 4 pads and is about 6 miles long.

This Tall VSM (Verticle Support Member) will carry the pipes up out of the rack and over to a UTILADOR, an underground chase-way that passes under the road.

This is the "Lay-Down" area, for construction material storeage. It's 500' by 900' built entirely on a frozen lake. This lake is frozen solid to the Perma frost.

Here 4 machines are preparing to pick up a length of pipe and set it on the VSM's.

This is the "OTHER" reason gas is expensive. It takes allot of man power and cash to get the crude to be processed! Thank you LYNDON! These are excellent pictures and gives us a better understanding of what goes on in Alaska.
 
Lyndon, Great thread. Thanks!!!

Can you tell us more about the water-in processing? In particular, is freezing an issue? Do I assume correctly you use sea water and pump it at a relatively high speed to keep it from freezing?

OK. Here's a quick 'Primer' on Oil recovery:
Imagine you are drilling into a ballon that is pressurized and two thirds full of liquid. Initially the pocket of oil and gas is pressurized. sometimes as high as 12,000PSI. Now you stick a straw down into the oil and the pressure pushes it up to the surface. But eventually the pressure plays out so you have to pump the oil up. Oil usually comes as a mixture of sand, water, oil and gas. the sand and gravel tends to wear-out or destroy your pump.

Rather than pumping it out of the formation, it's more practicle to Keep the formation pressurized. So we have massive gas turbines, that drive huge pumps. These often range in the 20,000 to 50,000 HP Range. As Oil floats on Water, we layer in water under the oil and esentially "float" it up and out. This also prevents the formation from collapsing. Besides the water we also use Natural gas to keep the formation pressurized. We DON't use Sea Water. Between the Salts and the Algea, it tends to generate H2S (Hydrogen Sulfide) some really nasty stuff. H2S is:1)Leathelly Toxic in just a 1% mixture, 2)Explosive, it doesn't just burn good, it explodes!, 3) Highly corrosive. this tends to eat up your pipe. So the answer is to De-salinate the water, essentially Distill it.

The water goes thru insulated, and heat traced pipes to prevent freezing. The oil, which is hot when it comes out of the ground, also get's heat traced and insulated. We even further heat the oil to make it easier to transport. There are some pictures of the Oil Heaters earlier in this thread. I'll look up the Post number here shortly.

The "Post" I thought had the heaters in it has them hidden behind a snow pile! The two stacks blowing smoke in this photo are Oil Heaters. I'll get some better pic's later in the day.

TRACK 14Where the pipeline job is underway. It serves all 4 pads. the little lake, just above and to the right of {2009 Tele Atlas} is where the 4 pictures of the "Lay-Down" yard in Post #343 were taken yesterday.

The "Pad" that CFP sits on is to the left of the orange markers on the left side of this photo. All this snow is on Tundra, beyond the Pad. The pad is 6 to 8 feet above the level of the Tundra. where I'm parked to take this picture my truck is sitting on about 10 to 12 feet of packed snow. the far right side of the snow pile is about 30 feet abouve the tundra. This snow pile covers several acres. Today our equipment operators got an award for doing the best snow removal job in Prudhoe! Go Loader Bob!
