... of target reservoirs. Improved understanding of the physics and chemistry of subsurface CO 2 flow for the purposes of geological storage is required. As CO 2 is injected, geochemical reactions between CO 2 , brine, and minerals will occur, and this can lead to formation damage which compromises...

... of these lower permeability reservoirs cannot be produced economically without a hydraulic fracture completion. To lower surface treating pressures to levels that can be managed within current frac boat and surface iron limits, heavy weight brines are often used as the base fluid for these frac gels...

.... Surface-coated silica nanoparticles create in-situ CO 2 foam, which has a more favorable mobility ratio and therefore better sweep. These nanoparticles can also be used in carbon capture and storage (CCS) applications in injecting CO 2 foam into brine aquifers. This paper presents the results of core...

... dispersions also have an excellent brine tolerance, demonstrating stable suspensions over weeks in fluids containing up to 150,000 mg/L TDS. The dispersions are stable at downhole relevant temperatures, applicable at low and high pH levels and resistant to shear degradation. Finally, MFC originates from...

This study describes how to address challenges such as depth correlation (which affects plug-setting depth accuracy), low injectivity, completion restrictions, and heavy brines (which damage CT). To gain further understanding of operations, simulations are sensitized to identify solutions...

Water cut sensitivity studies examined both, 35,000 TDS (seawater) and 125,000 TDS, brine conditions while the water cut was varied from 5% to 80...

... Abstract The use of high-density brines has been always considered as afactor in minimizing formation damage during completion operations. However, these brines can be potentially damaging if it is not well designed. Under high temperature conditions, precipitations may occurcausing a rapid...

... Abstract The Red Sea is a textbook case of a modern-day oceanic rift basin forming as a result of continental break-up. A characteristic feature of this setting in the central and northern Red Sea are more than two dozens of isolated bathymetric depressions, "deeps", filled with brines derived...
