Abstract
The production casing for a pair of hot dry rock (HDR) energy extraction wells had to be designed for unique conditions. Two hot dry rock wells (EE-2 and EE-3) were drilled and production casing installed at Fenton Hill, NM for the Los Alamos National Laboratory HDR program. The design of the production casing and subsequent completion operations in these wells revealed that thermal cycling , anticipated operating pressures, and wear during downhole operations are major considerations for both casing specifications and installation procedures. The first well (Energy Extraction N. 2; EE-2) is intended to be the injection well and EE-3 the production well. The top joint strain in EE-3 was monitored during installation, cementing and tensioning.
