Gas well flooding
Gas well flooding
(OP)
History- I am a civil engineer working on an old lanfil which is now used as a methan plant and distributor to frito lay. we began well maintainance here this month for the first time in several years and we are having a few problems with pumping out the wells.
Problem- these gas wells are ranged from 25 -65 feet of depth and some of them are flooded with rain water from over the years and also muck from the garbage it is getting methane from is mixed in the water. standard sump pump will work for a moment but will almost instantly clog with muck.
Question- What kind of pump or method may we use to get water out and Keep water out of the wells, (especially the ones to which consistantly let water in), so that the quality of methane stays it's best

You get resuspensioning pumps (the tend to be used in strom tanks to stop solids settling out) which might be used to get your muck into suspension so it can be pumped out by a submersible. Dont know what effect that will have on your methane.
Alternatively you might be able to use a positve displacement, sludge pump, type of arrangement. But that will depend on consistancy. This could be a diaphragm pump or a piston pump.
Is this permenant or temporary works? By the way, I have no idea on what affects quality of methane.

thanks tho for your help, I'm researching into them and will draw a conclusion from that. I just needed a starting point

Not ideal when man entry is required but I imagine that with methane you wont have anyone in from a confined space point of view.

Ussuri, I am trying to clean out gas wells that is only about 6 inches in diameter and 25-100foot depth which we would have no access too. we have a small diaphram pump which we've used for pumping out of our leachate tank and also used it on our smaller well but not for any of our deeper wells

Try typing 'air lifting on boreholes' into the google to see what comes back.It is abit more complecated and would involve positioning a drill rig back over the borehole to lower in metal rods through which we feed the compressed air. Again, this is obviously one step further involving more cost. It can be cheaper just to redrill a well adjacent.
