SVE well diameter

[cdale]

trying to decide if there is a significant benefit of larger 4-inch wells over 2-inch wells for an SVE system. going with 4-inch adds 2-3k to my cost of installation of the wells. i can't find much info to help me decide. what are the other factors should i consider? the borehole diameter/annualar space for sand pack will be about the same either way.

What does "SVE" mean ?

soil vapor extraction...

In addition to cost, you should also consider your expected extraction rate. Often 4-inch wells are selected over 2-inch because the 4-inch wells are capable of higher extraction flow rates and will experience less friction loss.
