We have seen cases in TX where naturally occurring radiation remained in O&G piping that was removed and “Upcycled” for reuse in boat docks and other similar uses. Suffice to say it didn’t end well.
It’s a cool idea, but gas wells have pretty small diameters. You’re basically going to have to use lead in your tubing to make this work. You’re also going to need long section of pipe which reduces your height off bottom. You’re also going to need to need to extract all the water from the heel up to counteract the buoyancy forces. One of the saving graces is that you might be able to use some of the bond to do a partial decommissioning. Getting rid of the water will require that you effectively seal the wells. Geothermal wells have much larger diameter and they already produce electricity. May be a good place to start, you could probably come in under an existing contract. Cyrq Energy and Ormat are probably the best orgs to talk to about this.
