I wish I had access to the geological survey as I would bet a very large sum of money there was a vent or laccolith within the area that has
fractured.
The way I see it from a not entirely lay view point is the fracturing known of in february is what accessed the vent/laccolith , this resulted in a
"hot burp" of gas that finished the well and has precipitated the complete well failure.
Now this could be a blessing or curse as the lava associated with such structures is extremely viscous and under ENORMOUS pressure. It does not
"flow" it is expressed like putty so could aid in sealing up some of the well damage to the sea floor, however if the flow reaches the near surface
and manages to raise temps even a couple degrees it can cause a catastrophic phase change in the clathrates adding significantly to the methane
release.
My main thought here is that the area is riddled with volcanic activities of various sorts from simple brine lakes due to surface infiltration of salt
domes heating up and flowing into the low spaces of the ocean floor forming dense brine lakes of highly concentrated salt solutions. to hot mud flows
and asphalt "volcanoes" all of which point to an interaction between the volcanic regions and the plutonic formations including the oil bearing
strata.
Given these hard facts regarding the area it seems unlikely there are many wells absolutely clear of volcanic intrusion in the gulf or out of reach if
a major fracturing takes place which is looking more and more like perhaps what the seismic anomaly recently reported was( I am talking a fracture
without subsiding or shift so no classic earthquake. However a fracture that has linked the original damage from feb to a volcanic region and is what
would cause the gas belch that rocked the rig to the floor and fracked the seafloor.
Again what I would not give for an accurate geological survey of the 40-50 mile radius around the well site as this would be easily deduced from such
by noting the structures which lie between this well and the nearest source of volcanism. A highly crystalline granitic structure is the norm for the
area and as such is more brittle than some other types of more amorphous materials so fracturing is the likely event given the material.
I hope I have clarified my points about not completely discounting a volcanic component to the whole disaster and how such is a very big candidate for
the final cause of the rig failure.
As well shed some light on the actual type of vulcanism which is now occurring all around the area.
