GLDA chelation lets seawater-based fracturing fluids maintain crosslinked viscosity and reduce formation damage from divalent ions.
A hardening fluid using calcium hydroxide nanocrystals, TEOS, and zinc sulfate strengthens acid-weakened wellbore walls and improves stability.
Layered direct ink writing forms a tougher wellbore cement composite that improves zonal isolation and helps prevent costly sheath failures.
Heating embedded eutectic alloy particles lets them melt into well cement fractures, then solidify to cut permeability and prevent annular pressure buildup.
A phosphonate acid blend improves wellbore scale inhibition in high-alkalinity, high-CO2 brines while maintaining stability and low corrosivity.
Higher-molecular-weight polyamides stabilize oilfield emulsions at high temperature while minimizing shale swelling and dispersion.
Swellable elastomer particulates in aqueous wellbore fluids form a filter cake that seals borehole walls, reduces fluid loss, and maintains stability.
Modified graphite-coated soft particles slow agglomeration and resist oxidation, enabling deep injection and durable water shutoff in hot, high-salt reservoirs.
An imidazolium-based aqueous inhibitor delays sulfate scale on HPHT wellbore walls, sustaining flow and avoiding acid washes.
A temperature-sensitive gel keeps foam stable in hot, high-salt gas wells, then weakens it at the wellhead to cut defoaming difficulty and chemical use.
Carboxybetaine zwitterionic surfactant in water-based drilling mud limits water uptake by shale, improving wellbore stability with lower toxicity.
A hydrophobic associative polymer improves slickwater shear resistance, drag reduction, and sand carrying in deep well fracturing.
A sulfobetaine zwitterionic surfactant delays sulfate scale onset in HPHT wellbores, protecting flow and equipment without acid washes.
Alkoxylated alcohol emulsions keep acid stimulation fluids stable at high temperature, improving acid placement while limiting corrosion and formation damage.
A high-pH drilling fluid with Mn-Zn-Fe layered triple hydroxide removes H2S in the wellbore while extending adsorption time and improving mud rheology.
