RE:RE:RE:AGMWhen you drill through a coal seam you need to be very careful with your drilling. Usually what happens is you get a drilling break, some very fast drilling as coal is easy to drill through. However, you need to stop drilling and work the pipe through the coal seam and let your drilling mud seal the coal seam. If you just drill through it and your drilling mud is doesn't have the correct properties, the coal will swell up and grab your drill string, then you are stuck. Because Tag sidetracked so much up the well they must have left some drillstring and tools in the well. If they would have been able to free the drill pipe, they would have not needed to sidetrack. Perhaps as well they lost a mud motor and a MWD tool. This will be costly. This will be a problem every time Tag drills through this coal seam. Coal is a bugger and you must be careful with it.
