Shappy,hi....thanx 4 the background!
Just a general remark here,because ESPH deals a lot with the consequences of hyraulic fracturing...
As all eyes are glued on the oil spill desaster in the golf,there was something happening badly in onshore-drilling as well,in Clearfield,Pennsylv.,as they were drilling for natural gas there,and the whole thing exploded,with all the pressurized,contaminated water thrown out again...it looks the seal was not working as it was designed for...i suppose,that going forward,a lot of legislation will be created to cater for the issue of onshore-drilling as well,and its impact on the environment...this agenda will be huge for ESPH,as there are many States in the US of A going to exploit shale gas now,and increasingly more in the future....just some thoughts thrown in;))
