My contractor (SW Ohio) has drilled the first of 3 holes, hit solid limestone at 20' all the way to 250'. U loop coils were just delivered and are 300' vs. 250'.

Should I have them drill the next two the additional 50' (wells are 16' apart, straight line). Will be reverse return and there would be 2@ 300' and 1 at 250 (already in well).

Tubing is 160 psi, 1". Grout is bentonite slurry.

So, is the extra 100' worth asking for more drill time (which won't be alot of cost...and I bought the crew lunch)...

What do you folks think... Crew will return at 8AM EST tomorrow...
