[QUOTE="Davy Crockett, post: 345679, member: 367"] WJ , The target formation for converted oil wells to water wells is the Fox Hills, probably around 1500 feet in that area of the state. I don't know much more about the program other than than that. I'd like to find one well location on a map and figure it out from there but my only guess that makes sense is these could be remote locations that ran the old stationary engines to pump the oil so no electricity ?? Getting electricity to the well location can cost more than drilling the water well in some cases , fox hills wells flow in lower areas. All just a guess while trying to figure out the feasibility of a project like this. They lay down the rods and tubing and most likely shoot off and lay down the 5-1/2 or what ever size casing below the target zone. But getting past the cement could be the hard part in my mind. Almost always the cement migrates back into the permeable formations plus who knows how big the annulus was washed out between the formation and surface casing with all the pump HP used while drilling surface.

When you clean your filters are you sure it's fine sand and not fine silt ? Easiest way is to take clean white 5 gal pail and run the hydrant with a hose and let it overflow for a while till you get some accumilated in the bottom then pour off the water and rub the contents with your finger , it will either smear or it will feel gritty. Without knowing the static water level and drawdown during enital well test and the screen/casing assembly it's about impossible to make a guess. You can PM me your location and I can find your well report online if you want or else I'd have to ask a bunch of questions before I could come up with a possible problem/solution. [/QUOTE]
