You seem somewhat knowledgeable with Methane geekery, so could give me some educated guesses?
I have seen some nice vids of burning tap water in kitchen sinks. How high would the methane concentration in water have to be, to achieve this
effect? Do you see any other circumstances, that are necessary for such an effect, other than methane concentrations?
Afaik depth currents in oceans can show some very peculiar attributes. There have been lots of methane gushed in the Gulf Basin lately. What do you
think, how high can the concentration in any given isolated stream or pool get?
I've spent my entire life in the gas processing industry. We are the downstream end of the oil and gas business. The next step after us is the
consumer. We work with natural gas and natural gas liquids (including crude oil) at temperatures and pressures similar to what the Maconda well is
leaking at. Actually we work with temperatures that are much colder. -166°F for Demethanizer overhead and -300°F for liquid methane / nitrogen
You will get more exposure to toxic things like Benzene from fueling your automobile and breathing fumes from that over your lifetime than you will
this spill. I never stand by my fuel nozzle when I'm fueling my car. I always turn the pump on and walk away. I do not return to the pump until it
clicks off. I would recommend that everyone do that.
Hydrocarbon phase behavior is an interesting topic. Especially when the hydrocarbon is a mixture at high pressure, somewhat cold temperatures, and in
the presence of water. Some of the Methane and Ethane (as well as other components), in the presence of water, at the conditions we are discussing,
will form a hydrate (which is a solid). Not might, will. The remaining components will exist as a liquid that contains methane, ethane, propane,
butane, pentane, hexane, etc. The liquid won't be as dense as the sea water but it will relatively close. That will allow it to remain in suspension
and slow it's rise to the surface (under water plumes). A couple of things complicate estimating what is happening in this situation. The use of
dispersants and the fact that the stream of hydrocarbon is being "jetted" into the surrounding water. There will be some "mixing" due to the
turbulence from the high velocity stream flowing into the surrounding sea water though not in the sense of a chemical bond forming. More like an
I don't know what to say about your methane / tap water vids. How did the methane get into the line? Did someone tap a gas line with a water line?
I've seen the results of what happens when someone accidentally tapped a fuel line and connected it to an air system. It was not pretty.
I think it's more than a little suspicious that I was told on 6/13 that the relief wells would be completed (by someone very close to the situation)
around 7/1 yet no mention of that was made of that until today and even then only briefly. In the meantime "they've" been ramping the flow
estimates up and fanning the flames of environmental discontent. I don't care what your degree is in or how long you've been doing what you do,
anyone that says that they know how much oil is coming out of the well is either a liar or an idiot. There is not enough information available to
accurately judge the flow from the well. This looks to me like a well orchestrated symphony of disinformation. For what purpose I am not sure.
