The driller is here. They have one well drilled to 200'. The next well is 15 feet away and they are going to use the slurry of this well to fill the first one and the third well slurry for the second. The first well drilling slurry is in a pit and they will fill the last well with that. They dug a trench between then and the slurry runs in the trench to the well hole.
The well are in a triangle 15' apart.
question: I asked about grout in the well and he stated he likes to use the watery drill slurry/millings first and than finish off with grout.
Is this correct?
Is 3 wells in triangle 15ft apart correct?
he says he does all his wells this way...
