Dr. Bart Verberne and co-workers at Utrecht University sought evidence for gas production-caused, permanent compaction in drill core from the Groningen gas reservoir sandstone. This research involved a multi-disciplinary approach involving lab work in the ESL and elaborate microstructural analyses in the MINT facility. Read all about their findings in their paper, or in the UU press release.
