16. It is only called "mud". It is actually a different material.
When I worked offshore oil we used barite, mixed with fresh water. It was a hell of a lot heavier that sea water. The weight of the column of barite countered the pressure of the oil and kept it down there until we were ready for it.

  -Why the hell can't they just pump sea water into it instead of mud which they will run out of Iwasthere  May-29-10 05:23 PM   #0 
  - I believe the viscosity of the mud helps hold back the oil comming out at 100,000psi  Odin2005   May-29-10 05:25 PM   #1 
  - That oil is under no such pressure.  RC   May-29-10 06:09 PM   #15 
     - You are neglecting the presssure of the miles of rock on the oil.  GreenStormCloud   May-29-10 06:18 PM   #19 
        - IIRC, and if BP isn't lying, the oil's at about 9,000 PSI.  backscatter712   May-29-10 06:23 PM   #22 
           - Apparently you have not seen any of the videos of the oil coming out of the pipe.  RC   May-29-10 06:34 PM   #24 
              - That would depend upon how big the escape hole is.  GreenStormCloud   May-29-10 06:42 PM   #25 
  - I think the idea is to put in something that goes in easy and comes out hard  HereSince1628   May-29-10 05:26 PM   #2 
  - Wow...that's gotta be the biggest leap I've ever seen here on DU...  PCIntern   May-29-10 05:27 PM   #5 
     - Yes, well it is BEST to be hyperbolic when answering  HereSince1628   May-29-10 05:43 PM   #11 
  - Not heavy enough. Once the well is filled, the column of mud must weigh enough to hold back  gristy   May-29-10 05:26 PM   #3 
  - That's what I've been reading too.  Trillo   May-29-10 06:21 PM   #21 
  - It's a pressure thing, has to be a dense material.  Avalux   May-29-10 05:26 PM   #4 
  - So what is the viscousity of the mud  Iwasthere   May-29-10 05:34 PM   #7 
     - the mud is quite viscous and heavy; they added pieces of rubber and golf balls to it.  Avalux   May-29-10 05:38 PM   #8 
     - I realize that  Iwasthere   May-29-10 05:46 PM   #12 
        - What do you suggest?  Avalux   May-29-10 06:32 PM   #23 
     - the viscosity is apparently...  IcyPeas   May-29-10 05:39 PM   #10 
     - The specific gravity of sea water is too small. Have you ever seen a rock float?  GreenStormCloud   May-29-10 06:16 PM   #17 
  - Perhaps corn starch as a thickener?  Warren Stupidity   May-29-10 05:28 PM   #6 
  - That's thinking in the right direction -- bentonite "mud" is actually referred to as "gel"  eppur_se_muova   May-30-10 01:29 AM   #32 
  - Fluid dynamics, sea water simply don't have the oomph for that  nadinbrzezinski   May-29-10 05:39 PM   #9 
  - This ain't mud like you played in as a child, its (there are many different kinds) very specialized  ThomWV   May-29-10 05:50 PM   #13 
  - Correct.  Ikonoklast   May-29-10 05:57 PM   #14 
     - I was working a well 17 miles from the Deepwater Horizon  TransitJohn   May-29-10 06:20 PM   #20 
        - The stuff I saw roughnecks using in OK looked more like a slurry.  Ikonoklast   May-29-10 06:50 PM   #26 
           - The pressure of the oil leaving the wellbore in this circumstance  TransitJohn   May-29-10 06:56 PM   #27 
              - What if it had a collector of some sort at the top?  Ikonoklast   May-29-10 07:11 PM   #28 
                 - Sounds interesting. N/T  GreenStormCloud   May-29-10 09:52 PM   #30 
  - It is only called "mud". It is actually a different material.  GreenStormCloud   May-29-10 06:13 PM   #16 
  - Well, you'll never get water to an ECD to equilibrate with the  TransitJohn   May-29-10 06:18 PM   #18 
  - That would help abate the flow of oil, but would not stop it.  WeDidIt   May-29-10 07:13 PM   #29 
  - Isn't the seafloor there like deep soft mud or quicksand?  Urban Prairie   May-29-10 10:11 PM   #31
