Descriptions
Hydrocarbon production from sandstone reservoirs causes elastic and inelastic reservoir compaction, potentially leading to surface subsidence and even seismicity, such as observed in the Groningen Gas Field, Netherlands. Inelastic compaction can partly be instantaneous, though rate-/time-dependent processes may play a role on the longer term. Therefore, compaction may continue even if production is stopped. To reliably evaluate the impact of post-abandonment behaviour, mechanism-based rate-/time-dependent compaction laws are needed. We performed triaxial compression experiments on Slochteren sandstone (reservoir of the Groningen field) samples, with porosity ϕ=14.6-18.9%, to investigate the effect of strain rate (rates of 10-6-10-8 s-1) under conventional triaxial and uniaxial strain (i.e. zero-lateral strain) boundary conditions. Complemented by additional experiments investigating effect of temperature and pore fluid pH, and microstructural analyses on undeformed and deformed materials, suggest that subcritical cracking, coupled with grain rearrangement, was the dominant mechanism causing inelastic deformation under triaxial and uniaxial strain conditions. The data provided in this dataset include mechanical and microstructural data on our Slochteren sandstone samples. The mechanical data were obtained from 11 conventional triaxial compression experiments at constant strain rate (abbreviated as “triaxial tests”), 9 uniaxial strain triaxial compression experiments at constant strain rate (abbreviated as “uniaxial strain tests”) and a single constant stress (creep) experiment (i.e. a “creep test”). The microstructural data include backscatter electron (BSE) images obtained for one undeformed sample and 6 deformed samples, and electron dispersive X-ray spectrometry (EDX) images on 5 undeformed samples.
