Abstract Scope |
Cementing geothermal wells that are used for energy production where higher temperatures have steam, or water and steam as continuous phases is challenging. Cementing issues between rock formations and casing may cause circulation loss and could potentially cause formation damage. Furthermore, wellbores are exposed to harsh fluids including geofluids, hydraulic fracturing fluid, drilling fluids, carbon dioxide, hydrogen sulfide, and more. In these conditions cement also undergoes expansion and contraction based on material thermal expansion as exposed to hot and cold cycles under the subsurface conditions. In cementing operations, use of suitable and sustainable additives can potentially improve the pore structure and mechanical strength thus preventing wellbore leakage by maintaining zonal isolation and enhancing mechanical strength. For this purpose, two sets of samples with: contaminating fluids and graphene nanoplatelets, at simulated thermal cycling were investigated to evaluate the petrophysical, microstructural, and micromechanical changes when compared to a control neat cement sample. |
