Juke, just trying to get my head around the situation. I believe the initial cleanup included an attempt to remove (most of) the filter cake before the perforated liner was set. Now the liner has been set, if we still have some remnant filter cake and other debris impeding flow, I would assume that has:
(a) now worked its way in to clog up the slots and possibly cake the inside of the liner? (b) formed around / blocking the areas around the outside of the liner?
In any case, am I correct in assuming the initial attempts to further clear the well would involve leaving the liner intact? Especially in the case of (b), is that where the well pressure techniques might come in, in effect acting like a suction, given that mechanical techniques would not be available?
I found references to some of these well clean up tools which I assume are used in these situations: http://www.well-flow.com/clean_up_tools.html http://www.well-flow.com/clean_up_chemicals.html
Perhaps the chemical solutions could also be used in this case?
I'm assuming the liner would only have to be removed in the worst case scenario.
Does this sound right?
