Here, we present observations of biogeochemical alteration of wellbore cement after interactions with H 2 . Experiments were conducted with a wellbore cement core and shale submerged in synthetic formation brine...

... the reactivity of wet supercritical CO 2 , at 150°F and 3000 psi on Portland cement plugs (class G), for exposure of up to 5 weeks. For nanoporous media, such as cement, diffusion is believed to be the major mass transport mechanism. To quantify the extent of the alteration (mineralization/dissolution) on fluid...

... can be effectively stimulated via hydraulic fracking. The industry currently uses several geochemical signals (e.g. Si/Al and Si/Zr) to identify authigenic silica phases present in an unconventional reservoir. Cemented horizons are prime candidates for placing hydraulic fracks due to the strengthening...

... Abstract Hydraulic fracturing operation is a common method to improve the production of unconventional reservoirs. Pressure cycles created by alternating loading and unloading procedures of hydraulic fracturing is a crucial factor impacting cement sheath integrity. At high pressure condition...
