re: Assumption Parish sink hole environmental impact: Links in OP

I am a drilling fluid specialist (aka mud engineer) if someone can get me the dimensions of the cavern I can tell you exactly how much fluid/mud would be needed to fill cavern. It looks like the best way to do this is drill a vent hole and then a fill hole as you fill cavern then vent to a vessel. Any idea how far the Miss River is from here? This would be my solution if the river is w/ in 20 miles. Run 2 lines from river to site. Bring a tanker up river from Dilling fluid facilities in Venice w/ mud/fluid. A large tanker full would more than likely carry enough to do job. Then have another tanker to take on the vented material in an enclosed enivironment. Running 2 temporary pipelines above ground 20 miles would take 2-3 days at most depending on terrain. Bring in a drilling rig w/ in a mile of site and directionaly drill into bottom of cavern and begin injecting heavy mud (depending on pressures) and let the stuff vent out. After it stabalizes pump some cement to seal off hole made in cavern for injection. I know it is more complicated than this but it is an idea.
