They were effected by fine migrations (which we knew) and that restricted gas flows The sizing of the proppants probably needs to be smaller Pumping of the proppants into the fractures needs to be done better There was some gel damage maybe originally from frac fluids due to poor gel breakers They may need to look at a clean out of the well
Apart from that everything is pretty much rosy!
They may need to build an underground processing facility as they are having that much trouble getting the gas out of the ground!!!!
