Drift Services Group’s Post

This week, an English man (Richard Lane) and an Irish man (Mark Smith) have been in Scotland and Wales – now there’s a joke in there somewhere other than the fact I’ve been nowhere. Basically, Paddy and Rich have been here there and everywhere mostly talking about properly engineering wells for open loop ground source heating projects. I made the really big mistake of asking what ‘properly engineering’ looks like. I wasn’t really interested. And you know that thing that happens when you say something and immediately regret it? Yeah. That happened. Because cue passionate and heated lecture about verticality, discharging and yields. So, just in case any of you Drifters need to know … one of the keys to the success of an open loop installation isn’t to just focus on your abstraction well, but your reinjection well as well (that’s too many wells). It’s about drilling in a straight line, maintaining critical verticality, it’s about the quality of the installation and ensuring care is taken when drilling to maximise yield. But it’s also about the potential for discharge and that you plan carefully to ensure the reinjection well is capable of taking the maximum volume of water back into the aquifer. Really wish I’d never asked – but at least they know what they are talking about, even if it is all…boring… And if you need boreholes planning and drilling perfectly, whether for water, ground source heat or any other reason, you know what to do. https://lnkd.in/eghWhi3M #GSHP #OpenLoop #Geothermal #Boreholes #WaterWells #AbstractionWell #Yawning #DrillingEngineering #GroundSourceHeat
