Fines Migration Versus Mineral Dissolution In Co₂ Injectivity Impairment: A Critical Review And Conceptual Framework For Clay-Rich Sandstone Reservoirs, Umarov Shahzodbek Bakhromjon Ugl

Platform: A Journal of Engineering

Sustained injectivity is a controlling operational requirement for geological CO2 storage in deep saline aquifers because near-wellbore permeability loss can restrict injection rates, accelerate pressure build-up and reduce storage efficiency. In sandstone reservoirs containing reactive or mobile clay minerals, CO2-saturated brine may induce coupled geochemical and colloidal processes that cannot be interpreted through bulk porosity change alone. This review critically synthesises evidence on CO2-brine-rock interaction, clay mineral response, fines detachment, pore-throat restriction and injectivity impairment in sandstone systems. The reviewed literature indicates that mineral dissolution, secondary precipitation, salt precipitation, wettability alteration and fines migration can operate simultaneously, but their effects …

Building An Inclusive Workforce: Closing Equity Gaps In Community Colleges And Vocational Schools With Elliott’S Embodied Inclusion 360 Framework Plain Language Summary, Niki Elliott Ph.D.

Inclusion in Postsecondary Education

This paper explains why community colleges and vocational schools need to do more to support students who are neurodiverse (such as students with ADHD, autism, dyslexia, or mental health conditions), especially students of color and men of color. Community colleges and vocational schools serve millions of students and are often the main path to good-paying jobs in the skilled trades. However, many students who enroll, especially students with disabilities and students of color, do not complete their programs. The article argues that schools must move beyond basic disability accommodations and instead redesign how they teach, support, and structure learning environments.
