Geothermal: TNO’s Rijswijk Centre for Sustainable Geo-energy (RCSG)
Project Description
An updated version of the 9-5/8” Enhanced Casing Installation (ECI), a level 3 Casing Drill system, with automated and mechanical Rotary Steerable System was tested using RCSG’s drill rig. The well was completed with sand screens placed over the Maassluis formation, composite casing featuring Huisman Geo’s unique coupling system, monitoring tubes and a glass fibre sensing system. One of the intended uses is to conduct tests required for the development of high temperature underground storage systems (HT-ATES).
Challenges
First time drilling with RCSG’s 160t rig; hybrid between water well & deep drilling equipment and requirements.
New Technology:
1. ECI’s automated Rotary Steerable System
2. Composite casing
3. Full well-length Glass fibre monitoring system
Role of WEP
Well engineering & operational support.
