The TEST CEM project presented at 56th US Rock Mechanics / Geomechanics Symposium

Posted August 15, 2022

The TEST CEM project was presented by Al Moghadam (TNO) at the 56th US Rock Mechanics / Geomechanics Symposium (Santa Fe, 26th-29th June 2022).

A methodology to model the stress evolution in cement plugs during hydration was presented.

New knowledge on cement behavior under lab and field conditions was shared and discussed, as for example how understanding the mechanisms responsible for the cement stress drop helps in designing better cement recipes that can maintain higher initial stress levels.

The well integrity modeling work was presented at the Celle Drilling 2022 conference (September 13-14)

Assessing the Impact of Temperature Cycles on well Cement in Low Enthalpy Geothermal Wells.

Current work on supercritical cement was presented at the Stanford Geothermal Workshop

Posted Nov. 1, 2021

This work is a part of a joint international effort to develop “sustainable geothermal well cement for challenging thermo-mechanical conditions” (Test-Cem) under the umbrella of Cofund GEOTHERMICA. The paper (below) describes an exploratory study of cementitious composites for applications in geothermal wells under super-critical conditions.
